Xinhuanet Wang Ying
Since January, the provinces have successively entered the local two sessions. At present, 30 provinces, autonomous regions and municipalities have held 2017 provincial-level local conferences, and local government work reports have also been released. At the two sessions, what small development and reform goals have been formulated by various provinces, and how to protect many social and livelihood topics that people care about? Let’s take a look.
Curing haze requires determination and goals.
In the winter of 2016, several rounds of smog that swept across many parts of the country made "governance" continue to be a high-frequency word in the work reports of local governments, and it has also become the top priority of this year’s work. To control smog, not only are all localities determined, but many provinces, including Beijing, Tianjin and Hebei, have also put forward clear targets for smog control.
Beijing proposed that in 2017, the average annual concentration of fine particles should be controlled at around 60 μ g/m3.
Tianjin proposed to switch to burning and shut down 7 coal-fired generating units and 380 coal-fired boilers, and shut down and eliminate 100 backward enterprises. The average annual concentration of PM2.5 decreased better than last year, and the national "Ten Atmosphere" target task was completed.
Hebei proposed that the average concentration of PM2.5 decreased by more than 6% this year.
Henan proposes to ensure that the concentrations of PM10 and PM2.5 decrease steadily, and the days with good air will last for more than 200 days.
Shaanxi proposed to strive to reduce the concentration of PM2.5 in Guanzhong area by more than 3% and increase the number of excellent days by an average of 5 days.
Jilin pointed out that the proportion of days with excellent ambient air quality in cities above prefecture level reached more than 75%.
Implement the river length system and take action in many places.
In December 2016, the "Opinions on Comprehensively Implementing the River Length System" issued by the Central Office and the State Council was announced, which clarified the main tasks of implementing the river length system and proposed to fully establish the river length system by the end of 2018. "Implement ‘ River length system ’ " It has become a key word in many local government work reports this year.
Ningxia proposed to implement the "river length system", strengthen the management of tributaries of the Yellow River, drainage ditches into the Yellow River, key lakes and urban black and odorous water bodies, completely ban the direct discharge of enterprises, severely crack down on the pollution of the Yellow River, and resolutely protect the "mother river".
Beijing has made it clear that it is necessary to strictly implement the "river length system", implement the regional compensation mechanism for water environment, and improve the water quality of national and municipal monitoring sections. We will build 29 ecologically clean small watersheds, complete the task of treating 57 sections of black and odorous water bodies, and completely eliminate the black and odorous water bodies in the built-up areas.
Yunnan proposes to pay close attention to the prevention and control of environmental pollution, fully implement the "river length system", and strengthen the protection and management of six major water systems such as the Yangtze River and the Pearl River and nine plateau lakes such as Dianchi Lake and Erhai Lake.
Digest "zombie enterprises" and continue to unswervingly go to production capacity
In December 2015, the Central Economic Work Conference listed "de-capacity" as the top five tasks of supply-side structural reform in 2016. In the past 2016, all localities have firmly "de-capacity", and key industries have achieved remarkable results in de-capacity. 2017 is the year of deepening supply-side structural reform. Accelerating structural adjustment and optimization, improving supply quality and level, and unswervingly "de-capacity" have become important topics in the work reports of local governments.
According to the actual situation of Hebei province, it is proposed that the word "go" should be the first, steel should be the most important, policy guidance should be strengthened, and strict investigation and verification should be carried out, and a ton of steel will never be added illegally.
Shanxi, Inner Mongolia and Qinghai all said that resolving excess production capacity will make better use of marketization and rule of law, and strictly implement relevant laws, regulations and standards on environmental protection, energy consumption, quality and safety.
Jilin’s goal of de-capacity in the new year is not only specific, but also specific to enterprises. It is clear that Tonggang Group will reduce the ironmaking capacity by 800,000 tons, and Yatai Cement and other enterprises will reduce the cement clinker capacity by 5 million tons.
Guangxi revealed that it will establish a database for "zombie enterprises" and establish a disposal mechanism for non-state-owned "zombie enterprises".
Anhui, Henan, Gansu and other places have also made firm determination to reduce production capacity in the government work report, and proposed that while completing the annual task of resolving excess capacity, it is necessary to prevent the resurgence of resolved excess capacity.
Sichuan and Yunnan clearly want to consolidate the achievements of steel de-capacity and severely crack down on illegal production and sales of "strip steel".
"Made in China" opens up new development ideas for all localities.
Overcapacity does not mean backwardness. To achieve better development of industries and enterprises, "de-capacity" must be coordinated with strategies such as "Made in China 2025" and "internet plus".
Zhang Qingwei, Governor of Hebei Province, said in his government work report that in 2016, the added value of equipment manufacturing industry in Hebei Province surpassed the iron and steel industry to become the first pillar industry. In 2017, Hebei will take intelligent manufacturing as the main direction, carry out special green manufacturing actions, and improve the quality and efficiency of traditional industries.
The work report of the Liaoning provincial government mentioned that in 2016, Liaoning implemented the Made in China 2025 Liaoning Action Program, and has promoted the construction of the first batch of 50 pilot demonstration enterprises for intelligent manufacturing and intelligent services, with high-end equipment manufacturing accounting for 17.2%. In 2017, we will aim at the middle and high end, consolidate and upgrade the equipment manufacturing industry, and promote the construction of 100 pilot demonstration enterprises for intelligent manufacturing and intelligent services.
Wang Xiaodong, acting governor of Hubei Province, said in his government work report that Hubei’s economy is in a difficult process of transforming old and new kinetic energy, and it is necessary to respond with new ones and adapt to changes, so that traditional kinetic energy can be rejuvenated and new kinetic energy can stir up the beam. In 2017, it is necessary to thoroughly implement the Made in China 2025 Hubei Action Plan and the Opinions on Accelerating the Implementation of internet plus Action, deepen the integrated development of manufacturing and Internet, focus on intelligent manufacturing, and accelerate the construction of a strong manufacturing province.
The government work reports of Ningxia and Xinjiang all mentioned the need to thoroughly implement the local action plan of Made in China 2025. Ningxia is particularly clear about speeding up the clean and efficient utilization and transformation of coal, and promoting the integrated and efficient development of coal chemical industry and petrochemical industry. In order to speed up the conversion of new and old kinetic energy, Xinjiang will support the technological innovation and transformation of traditional industries, promote the integration and development of manufacturing and the Internet, and promote the vitality of traditional kinetic energy.
Real estate regulation, destocking and stabilizing housing prices
Real estate destocking was an important part of local work last year. The Central Economic Work Conference held at the end of last year defined the development direction of China property market in 2017, and emphasized the need to promote the stable and healthy development of the real estate market. In 2017, many provinces continued to put the foothold of real estate regulation on destocking, and at the same time insisted on stabilizing the real estate market price.
The two sessions in Beijing pointed out that the goal of Beijing’s property market regulation is to stabilize housing prices and establish a long-term mechanism for real estate development. This year, we should vigorously promote the construction of affordable housing such as self-occupied housing and public rental housing, so that housing can truly return to the residential property.
In the government work report, Xinjiang Uygur Autonomous Region pointed out that the development of real estate industry should be organically combined with urbanization and urbanization of agricultural transfer population, and the real estate market should be regulated by classification and implemented according to the city and place to ensure a stable and healthy development.
Shenzhen proposes to adhere to the position that "houses are used for living, not for speculation", and comprehensively use financial, land and investment means to speed up research and establish a basic system and a long-term mechanism for the stable and healthy development of the real estate market to adapt to market rules, effectively reducing the "squeezing" impact of high housing prices on the real economy.
Shanghai also proposes to adhere to the positioning that "houses are used for living, not for speculation", strengthen the regulation of the real estate market, and strictly implement the regulation policies to promote the stable and healthy development of the real estate market. At the same time, Shanghai has put forward the goal of supplying 50,000 sets of various types of affordable housing.
Poverty alleviation, and the bottom line of people’s livelihood.
Development is for the people, and the results should benefit the people. In the crucial year of building a well-off society in an all-round way, all localities have paid more attention to poverty alleviation and improving people’s livelihood in their work.
Guizhou’s "Great Poverty Alleviation" strategy achieved gratifying results in 2016. Last year, Guizhou won the first battle to get rid of poverty, reducing the number of poor people by 1.208 million, launching the "first gun" of ex situ relocation and poverty alleviation throughout the country, and relocating 458,000 rural people. In 2017, Guizhou proposed to reduce the number of rural poor by more than 1 million.
In the work report of the Hunan provincial government, it is proposed that poverty alleviation should be taken as the first livelihood project to ensure that 1.1 million rural poor people will be reduced and 10 poverty-stricken counties and 2,500 poverty-stricken villages will be withdrawn this year.
This year, Hubei will continue to push forward poverty alleviation in a down-to-earth manner, and strive to lift 1.28 million people out of poverty this year, and nine poverty-stricken counties will take off their hats, and effectively implement all measures to tackle poverty from village to household.
Multi-measures continue to alleviate the difficulty and expensive medical treatment.
As an important concern in the field of people’s livelihood, the problem of difficult and expensive medical treatment has always been concerned. Adjusting the price of medical services, increasing the proportion of hospitalization reimbursement, and promoting the direct settlement of medical treatment for urban and rural residents in different places have been included in this year’s work plan by many local governments.
Beijing’s government work report puts forward that this year we should coordinate and promote the reform of medical care, medical insurance and medicine linkage, fully implement the separation of medicine, adjust the price of medical services, and promote the reform of compound medical insurance payment methods. At the same time, we should vigorously promote the sunshine procurement of drugs, improve the basic drug system, and promote the convergence of drug use between large hospitals and communities.
Tianjin has put forward the goal of "increasing the standard of residents’ medical insurance subsidy to 800 yuan and increasing the proportion of hospitalization reimbursement by 5 percentage points".
Hubei Province proposes to fully implement a unified basic medical insurance system for urban and rural residents, strengthen the effective connection of basic medical insurance, serious illness insurance and medical treatment, and ensure the direct settlement of medical treatment for urban and rural residents in different places.
It is clear that Henan should improve the pilot of instant settlement of medical treatment in different provinces, implement a unified basic medical insurance system for urban and rural residents, and raise the financial subsidy standard to 450 yuan per person per year.
Implementing the "Four Strictest" to Protect the Safety of Tongue Tip
Food is the most important thing for the people, and the safety on the tip of the tongue has always been concerned by the people. Strict food safety has also been written into this year’s work plan by many local governments. In view of the "safety on the tip of the tongue" of the people, many places emphasize the need to implement the "four strictest".
Tianjin listed "continuously strengthening the quality and safety supervision of food, medicine and agricultural products, so that the general public can eat with confidence" as this year’s work goal.
Hebei Province particularly emphasizes that it is necessary to implement the food and drug safety and security project in depth, continue to carry out centralized rectification of key areas, key areas and key links, adhere to the most stringent standards, the strictest supervision, the most severe punishment and the most serious accountability, and ensure the people’s "safety on the tip of the tongue".
Hubei’s government work report also made it clear that it is necessary to improve the unified and authoritative food and drug safety supervision system, implement the "four strictest" requirements, and ensure food and drug safety.
Guizhou also put forward the goal of "strictly implementing the food and drug safety responsibility system, strengthening inspection and testing, and improving the supervision system from production to consumption". (Comprehensive news from Xinhua News Agency, People’s Daily and Zhongxin. com)
How big is the power supply? I believe this is a problem that many DIY players will encounter when purchasing power. Most people’s solution is to follow the crowd, and I will choose how big others choose. In addition to seeking help in forums and post bars, the sales volume and evaluation of e-commerce platforms are also one of the reference standards.
Although this method can solve the problem of "which power supply to buy" temporarily, it can’t answer the fundamental question of "how much power to buy" in the long run. You can’t ask others for help every time you install the machine, can you?
So is there a way to do it once and for all without asking for help? Today, I will teach you a trick to easily choose the power supply suitable for your computer.
Let’s popularize the basic knowledge before teaching you how to choose the power supply suitable for your computer.
Our computer isIt is composed of CPU, graphics card, motherboard, memory, hard disk, peripherals and other hardware. When the computer is running, all parts of the hardware need to consume a certain amount of power. Generally speaking, the power consumption of CPU and graphics card is the highest, accounting for the vast majority of the overall power consumption of the computer.
Whether the computer can run stably is not only affected by the hardware itself, but also by the power supply that provides them with electricity.
Simply put, if the power consumption is higher than the overall power consumption of the whole machine, the computer will run stably; When the power supply is lower than the overall power consumption of the whole machine, it will be unstable. Therefore, it is particularly important to choose a power supply with sufficient power.
In fact, the solution is very simple, just buy a power supply with high power supply, but don’t forget that the higher the power supply often means the higher the price, and you need to pay more money for the high power supply.
The power calculator is good, but the update is not in place.
So, how can we calculate the overall power consumption required by the whole machine?
There are two ways, one is to calculate the overall power consumption of the whole machine through the known power consumption of each part of the hardware. Obviously, this method is time-consuming and laborious, and it is necessary not only to find the power consumption of each part of hardware, but also to add them one by one, which inevitably leads to the risk of mistakes.
The second method is obtained through a power calculator. There are some power calculators on the Internet. You can automatically calculate the required power by selecting the configuration of your computer, which is very convenient.
But most of these calculators are old, and the support for many new models of hardware is not in place. You may not find your own hardware at all.
PSU Calculator to find out.
The following is the key point that the author wants to talk about. Since the power calculator is more convenient than manual search, is there a power calculator that supports the existing hardware better?
The answer, of course, is yes, which is also the purpose of this paper. It is a power calculator from Cool Extreme.
This power calculator is called PSU Calculator, which can only be found from Cool Extreme. The English interface is not very friendly to us, but fortunately, the support for new hardware is good, and it can be found in 8-generation Core and 10-series graphics cards.
After opening the link of PSU Calculator, you can see a very detailed table, including motherboard, CPU, memory, graphics card, hard disk, keyboard and mouse, fan and other devices, and you can even overclock the frequency of CPU and graphics card to calculate the appropriate power supply. I have to say that this power calculator is very careful and worth learning from domestic manufacturers.
How many watts of power do the high, medium and low platforms need?
After knowing that there is a good thing called PSU Calculator, let’s try to calculate how many watts of power are needed for high, medium and low platforms based on the current mainstream hardware configuration.
1. High-end platform: i7-8700K+GTX 1080
Let’s take a look at the high-end platform of i7-8700K+GTX 1080. Other configurations are fixed as two 8GB memories, a SATA SSD+ and a 7200 rpm mechanical hard disk.
After selecting the configuration, click Calculate in the lower right corner to calculate the required power supply.
It can be seen that there are two powers in the lower right corner, one is Load Wattage, and the other is Recommended PSU Wattage. Load Wattage refers to the typical load of this configuration, such as the power required for running a 3D game, and Recommended PSU Wattage is the recommended power, which we shall take as the standard.
The typical load of this configuration is 401W, and the recommended power is 451W W. It can be seen that the power required by this high-end configuration is not as high as we thought, and the power supply of 500-600W can meet it.
For example, Hangjia’s JUMPER500 power supply has a rated power of 500W, and has passed the 80PLUS white-label certification, with 12V single-channel 40A current output and active PFC+ dual-transistor forward scheme. The price of 299 yuan is very cost-effective.
2. Mid-range platform: i5-8400+GTX 1060
For the mid-range platform, we take the i5-8400+GTX 1060 as an example. Other configurations are still fixed as two 8GB memories, a SATA SSD+ and a 7200 rpm mechanical hard disk. Calculated by PSU Calculator, this configuration only needs 362W W.
We can choose a 400W power supply for this mid-range configuration. For example, this Longba 400 power supply of Jinhetian has a rated power of 400W, adopts an enhanced 12V output (18A), double copper PCB design and a 12cm hydraulic fan. The power supply is stable and the heat dissipation is more efficient, and the price is only 159 yuan, which is very affordable.
3. Low-end platform: AMD Ruilong 2200G+ set display.
Here we positioned Ruilong 2200G as the living room entertainment center, so we didn’t increase the solo display. The recommended power calculated by PSU Calculator is 212W, and the power consumption is very low, so it is enough for us to choose a 300W power supply.
For example, the C5 power supply of Xingu, a nuclear-powered cruiser, has a rated power of 300W, a 12V output of 252W(21A), accounting for 84%, and the peak power can reach 400W W. Moreover, it adopts a 12cm PWM intelligent temperature control fan, which can reduce noise while providing large air output. The price is more affordable, only 119 yuan.
Well, the above is the author taking the current mainstream configuration as an example, and calculating the required power through PSU Calculator to choose the power supply he needs.
The purpose of this paper is to tell you that you can use PSU Calculator as a small tool when purchasing power supply, so you don’t have to ask for help from others or calculate manually. Interested friends may wish to collect it and try it first.

On October 29th, 220 provincial highway Qingtian-Taishun section of Taishun Nanpuxi-Xiaocun section and Taishun Fengyang-Shiyang section both passed the work feasibility review, which marked a substantial breakthrough in the preliminary work of Qingtian-Taishun section of 220 provincial highway.
The starting point of this project is located near Yangshan Township at the junction of Wencheng Taishun, connecting with Fenglin-Dongyang Section of Qingtian-Taishun Highway, passing through Nanpuxi Town and Xiaocun Town, and intersecting with Sixiao Line.
220 provincial highway Qingtian to Taishun highway Taishun Fengyang to Shiyang section, the starting point of this project is located in Yinshantang, southwest of Fengyang Township, which is connected with the connecting line of 331 provincial highway Xiaocun, passing through Sixi, Dongxi, Xuexi and Shiyang, and the ending point is connected with Wenfu Highway.
On October 29th, the Municipal Development and Reform Commission and the Municipal Transportation Bureau hosted a review meeting on the feasibility study report of the section of Qingtian-Taishun Highway 220 from Nanpuxi to Xiaocun in Taishun and the section of Qingtian-Taishun Highway 220 from Fengyang to Shiyang in Taishun. Provincial Highway and Transportation Management Center, representatives from Municipal Natural Resources and Planning Bureau, Water Conservancy Bureau, Ecological Environment Bureau, Shanguan Center, wencheng county Transportation Bureau, Taishun County and invited experts attended the meeting.
On October 28th, a group of experts made an on-the-spot reconnaissance to gain an in-depth understanding of the on-site situation of the project and the difficult problems existing in the promotion.
At the review meeting, the design unit reported the feasibility report document in detail, and the design consulting unit reported the preliminary review opinions. After carefully listening to the opinions and suggestions of various departments and towns, they exchanged views on the necessity of the project and the selection of the scheme, and the meeting passed the review opinions in principle.
At the meeting, the Municipal Transportation Bureau affirmed Taishun’s work of "doing big traffic and doing big traffic", and gave strong support to the promotion of Taishun section of Qingtian-Taishun Highway of Provincial Highway 220. At the same time, combined with the preliminary work of Taicang Expressway and the future tourism development corridor, it put forward opinions and suggestions on the guarantee of factors such as project prophase, capital and land use.
Cheng Yi, deputy county magistrate, said that the construction of this project is of great significance for the towns and villages along the line to realize the "fast outside and smooth inside" traffic, and should meet the travel needs of the people to the maximum extent. With the Wen Tai Expressway about to be completed and opened to traffic, it is necessary to promote the deep integration and development of the eco-tourism industry in the towns and villages along the line, optimize the industrial layout and reserve development space. It is necessary to closely focus on the development idea of "establishing a county by ecology and rising green" and minimize the interference to the environment on the basis of meeting the technical indicators.
It is reported that the planned 220 provincial highway from Qingtian to Taishun (to be approved) starts from qingtian county, Lishui, enters Zherong County, Fujian Province, and connects with the planned provincial highway in Fujian. Among them, the Taishun section of scripture is connected with Taishun Lianyun after it becomes Yangshan Mountain, and enters Fujian after passing through Nanpuxi Town, Shinohara Village, sixi town, Dongxi Town and Shiyang Town.
Taishun section of Qingtian-Taishun Highway of 220 Provincial Highway is the main communication channel to speed up the construction of north-south traffic in the region, which will improve the layout of the national and provincial trunk highway network in Zhejiang Province and further promote the economic and social development in the border areas of Zhejiang and Fujian. At present, the engineering feasibility, preliminary design and construction drawing review have been completed in the sections from Fenglin to Dongyang in Xiaocun and from Shiyang to Zhejiang and Fujian.

August is coming, and the long summer vacation is drawing to a close. For the "Little Bean Bag" and parents who are about to enter the first grade, the rest of the time is full of expectation and anxiety. So, how can we help "children" transition to "primary school students"? What preparations should parents make? The reporter interviewed relevant experts.
Listening to the weather forecast and remembering the temperature helps to exercise children’s concentration.
"After entering the first grade of primary school, children are particularly prone to discomfort in four aspects: schedule, attention, self-care ability and living habits." At the 48th public lecture of Haidian Family Education Lecture Hall held recently, Xiao Ying, the principal of the primary school affiliated to Beijing Petroleum Institute, shared with her parents the experience of making a good connection between young and old.
Xiao Ying said that in terms of schedule, kindergartens mainly focus on activities and games, and there are not many teaching activities. The primary school has a systematic three-level curriculum, no special nap time, and the schedule is completely different from that of kindergarten. Therefore, it is easy for children to get up in the morning and doze off in the afternoon after entering school. In this regard, she suggested that parents should arrange their schedules reasonably and try to put their children to sleep around 8: 30 in the evening. In addition to going to sleep early at night, parents can consciously train their children not to take a nap or take a purposeful trip from August, so that children can gradually get used to not taking a nap.
Xiao Ying also found that primary school students who have just entered the first grade still have problems such as not being able to dress themselves, tie their shoelaces, pack their schoolbags, not caring for their school equipment and drinking water on their own initiative. She suggested that parents can help their children master their self-care ability by teaching methods, deliberate repeated practice, inspection and supervision. At the same time, it is also necessary to cultivate children to actively develop health habits and etiquette habits that are suitable for primary school learning.
Lack of concentration is also a big challenge. Xiao Ying said that the concentration time of primary school students is between 20 minutes and 25 minutes, which is because the development of children’s nervous system is still developing. With the increase of age, the situation of inattention will gradually improve. Parents can help their children improve their attention in advance through a series of methods. For example, exercise concentration by listening to the weather forecast and recording the temperature of each city; Train the breadth of attention by listening to the extended sentences and repeating them. "These methods are mainly through language communication, so that children can grab words and keywords, thus improving their attention. In addition, you can also play games such as catching and throwing balls with your children to improve your attention. "
Don’t go to preschool blindly, which will easily lead to inattention.
With the approach of school, the psychological counseling center of primary and secondary schools in Beijing has received many anxious and confused parents. One of the topics that parents are most concerned about is whether it is necessary to "stupid birds fly first" and use the summer vacation time before entering primary school to find one-on-one tutoring or enroll their children in preschool classes.
Wen Fang, director of the psychological counseling center for primary and secondary schools in Beijing, gave his own advice from the perspective of psychological development. The most direct consequence of "flying first for a while" during the holiday is that children lose the patience to listen carefully when they get to class. "There is nothing to learn in class, and children are easy to stay. In the long run, it is easy to cause bad habits of inattention. When it comes to in-depth and difficult parts, children are not willing to listen. "
Chu Zhaohui, a researcher at the China Academy of Educational Sciences, said that parents should take a long-term view in terms of children’s growth and development. He told reporters that there is a famous "twin climbing stairs" experiment in psychology: let a pair of identical twins practice climbing stairs, and one of them starts practicing in the 48 th week after birth and practices for 10 minutes every day; The other started the same training at the 53rd week after birth. At 54 weeks, one child practiced for 7 weeks, while the other only practiced for 2 weeks. So, which of the two children climbs the stairs at a higher level? The experimental results are unexpected. Children who have only practiced for two weeks can climb stairs faster. "Therefore, some training institutions claim that after training, children are more focused and their memory is enhanced compared with untrained children. In fact, such a comparison is of no value to children’s growth and development, because some abilities can be naturally developed by children after a certain period of time. "
Li Zhuo, the lifelong honorary principal of Beijing Shijia Primary School, specially wrote a parent handbook "Welcome to Grade One" for parents who are facing young convergence. He introduced that in some countries in East Asia and Europe, children began to attend the first grade at the age of 5. What is the purpose of 5-year-old children trying to learn in class? In order to understand the rules of the classroom and sit still in the classroom. From this point of view, it is still very valuable to enter the preschool training place to experience it. However, it should be noted that the preschool class is to feel the upcoming classroom learning style in advance, rather than to receive the knowledge of the first and second grades of primary school in advance. In addition, another important role of preschool classes is to let children show some possible problems in advance in the upcoming primary school life. In this way, parents can be reminded in time so as to find countermeasures earlier.
Excessive expectation and extreme weariness of learning, and school attitude reflects family problems.
Taotao is going to primary school soon. Within a few days of receiving the notice, the school organized entrance education to help them know the new environment they will study in advance and know their future classmates. Unexpectedly, after entering the school, he added a new habit in this holiday: grinding his grandfather to go to his new school every day. When the school is closed during the holidays, he just looks at the door for half a day. The scorching sun often makes him sweat all over, but grandpa can’t even persuade him to go to a cool place. Grandpa was distressed and helpless, so he had to find the psychological counseling center of primary and secondary schools in Beijing. "Is my grandson sick?"
Contrary to surging, there is another extreme who comes to the psychological counseling center of primary and secondary schools in Beijing: in the distant home, "going to school" has almost become a taboo topic at home. As long as someone mentions going to primary school, Yao Yao immediately turns his face and cries and makes trouble. Mom and dad are very worried. "I’m tired of learning like this before I go to school. What can I do in the future?"
Director Wen Fang said that both extreme psychological states need to attract parents’ attention. Generally speaking, the extreme expectation of going to school shows that children feel the lack of emotion in the family. "Adults at home pay little attention and have to look forward to looking for attention in the new environment outside." He reminded that children in this situation are easy to "make bad friends" and are eager to find channels for emotional communication and venting, so "bad companions" have an opportunity.
However, children’s mentality of avoiding going to school reflects the opposite state. "This kind of child tends to rely too much on family ties, which is not conducive to the child’s transformation from a natural person to a social person." Wen Fang suggested that in this case, the family environment and work standards should strive to be in line with the school. Parents should not do everything, but encourage their children to take the first step independently.
Who is in charge of children’s schooling? Consistency in family education is very important.
Recently, the psychological counseling center of primary and secondary schools in Beijing has also received counseling from many family groups. Before the children went to school, there were signs of internal family wars. Take Nuo Nuo’s family as an example. Parents’ commuting time conflicts with school time, so they can’t pick up and drop off, so they have to leave this arduous task to their grandparents. Unexpectedly, my grandparents insisted on one point: "Since the children are here, we have to listen to everything, and parents have to give up." The two sides couldn’t talk it over, so they came to the consultation center for expert help.
Director Wen Fang said that a very important principle in family education is "consistency". He put forward several four-word principles: division of labor and cooperation, cooperation and co-management; Close contact to enhance trust; Actively demonstrate and comply with regulations; Grasp the principle and give priority to development.
In fact, parents who have no time to take care of their children full-time do not need to feel sorry and worry too much. A previous survey report by the Family Education Committee of China Education Association showed that grandparents’ participation in parenting would not adversely affect the parent-child relationship between parents and children; If grandparents only partially participate in children’s upbringing and do not play a leading role in it, it will not have a negative impact on children’s adaptability to life.
In the handbook for parents, President Li Zhuo also analyzed the question of "who will take care of the children". Nowadays, most of the young parents work full-time. At the beginning of school, most parents will discuss who has more flexible working hours and who has more energy after work, who will mainly manage the children’s study. "It is important to have available time and energy, but over the years, after contacting many parents with different personalities and different communication methods, I think the best choice criterion for this matter is: who is more willing to take care of the children." President Li Zhuo said.
Li Zhuo said that because of the will, it is easier to find management methods, spend more time observing children, have more patience to communicate with children, and help children sum up rules and skills. If, unfortunately, the party who is more willing to do it is busy, then the two sides can negotiate a good division of labor after full discussion. For example, after a plan is made, it will be implemented by the party with more time, and the children will continue to feedback and adjust each other during the learning process until they find the most suitable rhythm and form of family learning.

According to the news of @ Look at the Taiwan Strait on June 6, one more dead person and a 53-year-old woman were killed in the poisoning case of Baolin Tea Room in Taipei, which caused septic shock yesterday (5) and was finally declared dead.
According to Taiwan media citing local health bureau data, at present,A total of 24 cases were reported in the Baolin case, of which 5 died and 1 was still being treated.The remaining 18 people have returned home to recuperate.
[previously reported]
On the evening of March 28th, the Health and Welfare Department of Taiwan Province held a press conference to introduce the investigation progress of the suspected food poisoning incident in "Baolin Tea Room" in Taipei, saying that after the autopsy analysis of the first death case,It was confirmed that the toxic substance "rice yeast acid" was detected..
All cases had a meal in a "Baolin Tea Room" in Xinyi District from March 19th to 22nd, and they ate food made of the same ingredients, such as kway teow and rice flour, and all of them had symptoms within a short time after eating, among which acute liver failure and other organ failure would occur in severe cases.
"rice fermentative acid"1 mg can be fatal.
According to reports,
"rice fermentative acid"
Fermented grains, coconuts and edible fungi, etc.
Produce after pollution
Strong toxicity, colorless and tasteless.
And is stable at high temperature.
It mainly affects important organs such as liver, brain and kidney.
It only takes 1 mg to kill.
"rice fermentative acid"
It is also fermented corn flour products and deteriorated fresh tremella.
And other metamorphic starch products.
The main cause of food poisoning.
As "frequent visitors" on people’s dining tables, starch foods such as cold rice noodles, rice rolls, and potato flour kway teow may be contaminated under the conditions of unsanitary environment, deteriorated raw materials, improper storage, prolonged soaking and humid storage environment.
Rice yeast acid has strong heat resistance, which can not be destroyed by boiling at 100℃ or high-pressure cooking (120℃). After eating, it will cause poisoning, and the onset of poisoning is acute and the disease develops rapidly. Once the food contaminated with rice yeast acid is eaten, the incubation period is usually 30 minutes to 12 hours, and a few of them are one or two days.
The first manifestations are nausea and vomiting, diarrhea and abdominal pain, dizziness and weakness.
In severe cases, headache, muscle spasm, jaundice, hepatomegaly, subcutaneous hemorrhage, hematemesis, hematuria, oliguria, unconsciousness, irritability, shock and even death occur.
At present, there is no specific antidote, and the mortality rate of acidosis by Aspergillus oryzae is over 50%.
There are many cases of "rice yeast acid" poisoning.
As early as 2018,
A seven-year-old girl from Zhejiang
Because of eating soaked for 2 days and 2 nights.
Poisoning by black fungus
Lead to systemic multiple organ failure
After more than a week of rescue
Whole body blood was replaced four times.
Still didn’t wake up.
In fact, dried auricularia auricula itself is not toxic, but auricularia auricula may produce a kind of bacteria called "Pseudomonas cocoanum" in the process of foaming, which will produce mycotoxins.
July 2023
Xiaolan (pseudonym) and aunt in Yongcheng, Henan Province
Poisoning after eating cold rice noodles
My aunt died unfortunately
The doctor told his family
Two people are acidosis by rice yeast.
In this regard, many netizens said that
"Fresh ingredients are the most important"
How to prevent "rice yeast acid" poisoning?
Experts suggest that before eating fermented food, make sure its storage, processing and cooking methods are correct to avoid eating expired or deteriorated food. When eating fermented food, we should pay attention to hygiene and avoid cross-contamination. When making fermented food, we should pay attention to hygiene and temperature control to avoid bacterial growth.
"Once you suspect that you or your family members have" rice yeast acid "poisoning, you can stimulate your throat with chopsticks or fingers to induce vomiting and vomit the food you just ate." If you are suspected of eating "fermented rice acid" by mistake, experts suggest vomiting as soon as possible, and keep the rest of the food for medical inspection.
After the diagnosis is confirmed, the patient can be treated with hemodialysis according to the clinical symptoms, and the symptomatic treatment can be given according to the severity of the disease.
△ Video: "Challenge Impossible"
CCTV News:Today is "119" Fire Day, and some people call fire fighters "retrograde heroes", because whenever there is a crisis, all people are retreating backwards, and only fire officers and soldiers are going retrograde. Touched by the spirit of courage to take responsibility and dedication for these lovely people, their superb skills are also impressive and admirable.
No, recently, an armed police fire fighter in Gansu province showed his exquisite skill of blindly cutting steel wires on light bulbs with a toothless saw in the inspirational program "Challenge Impossible".
Fire fighters blindly cut steel wire bulbs on the bulbs without any damage.
The soldier’s name is Li Haifeng, and his challenge is to blindly cut the steel wire fixed above the light bulb through a thick steel plate with a toothless saw.
△ Toothless saw
The distance between the steel wire and the bulb is only 0.01 mm.
After 45 seconds, the steel wire broke with a bang, and Li Haifeng quickly received the force, and the light bulb was not damaged at all.
In the end, Li Haifeng challenged successfully and won applause and exclamations at the scene. Of course, such skills are not limited to stage performances, but are more used in Li Haifeng’s rescue work.
For example, once, a 16-year-old boy couldn’t get the ring off his hand. After trying to cut the ring with tools such as steel bar breaker, pliers and saw, Li Haifeng decided to use a toothless saw.
He wrapped the boy’s hand with a towel in order to prevent the sparks from cutting from hurting his skin. During the cutting process, he kept watering the boy’s hands to cool down because of the fever.
In the end, Li Haifeng sawed off the ring with a toothless saw and successfully saved the boy’s finger.
After 17 years of practice, I have developed an extraordinary stunt.
When Li Haifeng challenged to cut the steel wire, he relied on hearing and touch. He said, "The right ear captures the sound of the engine, and the left ear distinguishes the friction of the grinding wheel." The summary of a short sentence embodies the sweat and hardships of 17 years.
In 1999, 19-year-old Li Haifeng joined the army from Hebei and became a fire fighter of Gansu Baiyin Fire Brigade. A few years before joining the army, Li Haifeng has been the squad leader of the rescue class, specializing in demolition technology. In 2010, he began to try to cut the steel wire on the light bulb with a toothless saw. From the initial watching to the later blindfolded cutting, Li Haifeng exchanged three years of tenacity and sweat for the unique skills in the country today.
"In three years, I chopped up more than 1,000 light bulbs." Li Haifeng said that from the initial lack of confidence and the discouragement of countless failures, he experienced painful hardships again and again. "Now, I have formed a deep feeling with the light bulb."
Facing the test of life and death, be a pioneer in emergency rescue again and again.
Since joining the army at the end of 1999, this military uniform has given Li Haifeng a strong sense of mission. At the age of 36, he rescued 188 people in distress, protected tens of millions of materials and property, and won many honors. He is currently the deputy director of the training department of Gansu Provincial Public Security Fire Brigade, and his injuries are as many as the awards he won.
Over-training and accidents in many rescue accidents, Li Haifeng suffered six fractures, numerous minor injuries, severe varicose veins in both legs, and unbearable pain at the fracture site every cloudy day. And he said: "There will be a lot of aerial work in fire fighting and rescue, and there will be many accidents in emergency rescue, which will inevitably lead to sprains and bruises, which is normal."
△ Li Haifeng blindly cut the steel wire fixed above the bulb through a thick steel plate with a toothless saw.
Now I have a skill, but I was afraid at the beginning. Li Haifeng recalled that in 2000, not long after he joined the army, he once performed a extinguishing task, and the squad leader asked Li Haifeng to set up the gas tank. "After the rescue of personnel was completed, in the face of the explosion of liquefied gas at any time, at the moment when all firefighters were ready to evacuate, the captain asked me to help the liquefied gas tank immediately. To be honest, I hesitated for a moment, because I was really scared. The liquefied gas tank was still breathing fire and could explode at any time. " Despite his inner fear, Li Haifeng did it at once. Just turning 20, he felt as if he had passed by death.
△ Li Haifeng participated in the second season of "Challenge Impossible".
I have participated in various rescues for more than 3,000 times in 17 years, but the more I have seen life and death, the deeper I feel awe. "I remember a multi-person car accident in Baiyin No.1 Road in 2013. When we rescued one of the ladies, she had no signs of life. At that time, her son kept crying, and her husband immediately knelt down and kept kowtowing to us and begged us to save her. At that time, I felt my heart was bleeding, and I really felt very ‘ Incompetence ’ . Life is particularly fragile, and all fame and fortune are not important in front of life. "
This job also gives Li Haifeng few opportunities to reunite with his family. Li Haifeng’s wife said in the program, "Although we get together less and leave more, the day we marry Li Haifeng, we are ready for all the psychological preparations we need to bear as a military spouse." A simple sentence made the host Dong Qing and many viewers shed tears on the spot.
Li Haifeng’s soul-shaking skill display is precisely because of his deep sense of responsibility and mission. He explained the word "hero" in peacetime with the most practical actions.
According to the website of the Emergency Management Department, the Emergency Management Department released the basic situation of natural disasters in 2022 on the 13th. In the whole year, 112 million people were affected by various natural disasters, 554 people died and disappeared due to disasters, and 2.428 million people were resettled. 47,000 houses collapsed and 796,000 houses were damaged to varying degrees; The affected area of crops is 12,071.6 thousand hectares; The direct economic loss was 238.65 billion yuan. Compared with the average in recent five years, the number of people who died and disappeared, the number of houses collapsed and the direct economic losses decreased by 30.8%, 63.3% and 25.3% respectively.
According to reports, the Ministry of Emergency Management, together with the Ministry of Industry and Information Technology, the Ministry of Natural Resources, the Ministry of Housing and Urban-Rural Development, the Ministry of Transport, the Ministry of Water Resources, the Ministry of Agriculture and Rural Affairs, the Health and Wellness Commission, the Statistics Bureau, the Meteorological Bureau, China Banking and Insurance Regulatory Commission, the Grain and Material Reserve Bureau, the Forestry and Grass Bureau, the China Red Cross Society, China State Railway Group Co.,Ltd. and other departments and units, approved that in 2022, China’s natural disasters will be dominated by floods, droughts, windstorms, earthquakes and geological disasters.
Affected by extreme weather, major disasters occurred, such as floods in the Pearl River basin, breaches of the Raoyang River, a tributary of the Liaohe River, flash floods in Datong, Qinghai, Pingwu and Beichuan in Sichuan, droughts in summer, autumn and winter in the Yangtze River basin, and forest fires in southern China. The Luding 6.8 earthquake in Sichuan caused heavy casualties. The Emergency Management Department strengthened overall coordination, made every effort to do a good job in emergency rescue and disaster relief, and minimized casualties and property losses.
The main features of national natural disasters in 2022 are:
First, the distribution of natural disasters in China is uneven in time and space, with frequent occurrences in summer and autumn and severe disasters in the central and western regions.
From January to April, the disaster situation was generally stable and light, except for the 6.9 earthquake in Menyuan, Qinghai Province on January 8 and the freezing rain and snow disaster in some parts of southern China in February. After entering summer and autumn, severe rainstorm and flood disasters occurred in South China, Jiangnan and Liaohe River Basin, rare drought in summer and autumn and winter in Yangtze River Basin, local mountain torrents and mudslides in Sichuan, Heilongjiang, Gansu and Qinghai, as well as major disasters such as Lushan 6.1 earthquake in Sichuan, Marcand 6.0 earthquake swarm and Luding 6.8 earthquake. During the period from long summer to beginning of winter, the number of deaths, disappearances and direct economic losses caused by various natural disasters accounted for 92% and 91% of the total annual losses respectively. There are 10 provinces with direct economic losses of over 10 billion yuan due to disasters throughout the year.
Second, the flood disaster is "heavy in the north and south, light in the middle", and local mountain torrents frequently recur.
In 2022, there were 38 regional rainstorm processes in China, with an average precipitation of 606.1 mm, 5% less than normal. Floods exceeding the warning level occurred in 626 rivers in 28 provinces across the country, and there were 10 numbered floods in large rivers. Among them, the Pearl River Basin formed two consecutive large floods, and the Beijiang River experienced the biggest flood since 1915. The biggest flood occurred in Liaohe since 1995; The flood situation of the Yellow River, Huaihe River and Haihe River is generally stable. South China has experienced nine regional rainstorm processes in the first flood season, and the precipitation in the Pearl River Basin is the highest in the same period since 1961, resulting in large basin floods. In July and August, serious floods occurred in Liaohe River Basin. Sudden flash floods in Sichuan, Qinghai and other places caused heavy casualties. In the whole year, 33.853 million people were affected by floods, 171 people died and disappeared due to disasters, and the direct economic loss was 128.9 billion yuan. In addition, there are 5,659 geological disasters such as landslides, collapses and mudslides in China, mainly small and medium-sized, mainly concentrated in Central South, South China and Southwest China.
Three, the Yangtze River Basin has a rare history of continuous drought in summer, autumn and winter, which has a wide range of influences and heavy losses.
In 2022, affected by the strong subtropical high and La Ni? a phenomenon, the average temperature in China was high, and there were successive droughts in winter and spring in the Pearl River basin at the beginning of the year, in spring and summer in Huanghuaihai and Northwest China from April to June, and in summer, autumn and winter in the Yangtze River basin. Among them, the drought in the Yangtze River basin is the most serious meteorological and hydrological drought since the complete measured data are available, and the number of days above the moderate drought is 77 days, 54 days more than the normal period, which is the highest in the historical period since 1961. At the peak of the drought, 52.452 million people were affected, 7.585 million people needed life assistance due to the drought, the affected area of crops was 60.902 thousand hectares, and the direct economic loss was 51.28 billion yuan.
Fourth, the temporal and spatial distribution of forest and grassland fires is relatively concentrated.
In 2022, there were 709 forest fires in China, with an area of 4,689.5 hectares of forest affected and 17 people killed. In terms of time distribution, March-April and September-October are the high incidence periods of forest fires, with 521 cases, accounting for 74% of the whole year. In terms of spatial distribution, affected by factors such as high temperature and drought, there were 503 forest fires in six provinces of Hunan, Guangxi, Jiangxi, Hubei, Guangdong and Chongqing, accounting for 71% of the country. There were 21 grassland fires in China, including 16 in Inner Mongolia and Qinghai, accounting for 76% of the country.
Five, the strong convective weather process is less, the wind and hail disasters are lighter, and the lightning strike events are relatively prominent.
In 2022, there were 37 regional strong convective weather processes in China, the number of which was less than the average in recent years. From the time point of view, it is mainly concentrated in summer, and the number of deaths and missing persons and direct economic losses caused by strong convective weather account for 73% and 69% of the annual losses caused by wind and hail disasters respectively. Regionally, it is mainly distributed in North China, Northwest China and Southwest China. There are many casualties caused by lightning strikes in Qinghai and Sichuan. On the whole, the wind and hail disasters in 2022 were lighter than normal, causing 9.306 million people to be affected, 88 people died and the direct economic loss was 16.67 billion yuan.
Six, moderate and strong earthquakes in the western region are more active, and the loss of earthquake disasters is biased.
In 2022, there were 27 earthquakes of magnitude 5 or above in mainland China, which increased on average compared with previous years, mainly concentrated in western areas such as Qinghai, Sichuan and Xinjiang. The earthquake with the highest magnitude in the whole year was the Menyuan M6.9 earthquake in Qinghai on January 8, and the earthquake with the heaviest loss was the Luding M6.8 earthquake in Sichuan on September 5. In 2022, the earthquake disaster losses were heavier than normal, resulting in a total of 940,000 people affected, 122 people died and disappeared due to the disaster, and the direct economic loss was 22.45 billion yuan.
Seven, the number of typhoons landing is small, and the landing sites are relatively concentrated.
In 2022, there were 25 typhoons in the Pacific Northwest and the South China Sea, which was basically the same as normal, and four of them landed in China, which was less than normal. On July 2nd, Typhoon No.3 "Siam Ba" landed on the coast of Dianbai, Guangdong, becoming the first typhoon to land. Three of the four landfall typhoons landed in Guangdong, and the 12th typhoon "Meihua" landed four times in Zhoushan, Zhejiang, Fengxian, Shanghai, Qingdao, Shandong and Dalian, Liaoning, which was the first typhoon to land in different parts of mainland China for four times since 1949. The direct economic loss caused by typhoon disaster in 2022 was 5.42 billion yuan, which was lighter than normal.
8. Low temperature rain, snow and freezing affect the southwest and central and southern regions, and the local snowstorm in Xinjiang is serious.
In 2022, China was affected by 35 cold air processes, 5.9 times more than normal. In February, the average temperature in the south was the lowest in the same period since 2009. The southwest and central and southern regions were seriously affected by the low-temperature rain, snow and freezing disasters, and the direct economic losses accounted for 80% of the annual losses caused by the low-temperature rain, snow and freezing disasters. From November 26th to December 1st, the strongest cold wave weather since winter brought severe cooling, strong winds and dust, rain and snow to most parts of the country, and extreme snowstorms in Altay and Tacheng areas of Xinjiang caused casualties. In 2022, low-temperature freezing and snowstorm caused a total of 870.7 thousand hectares of crops to be affected, and the direct economic loss was 12.45 billion yuan.
CCTV News:Coal-fired power generation will remain the main part of China’s power supply structure for a long time. Data show that in 2018, China’s installed power capacity reached 1.9 billion kilowatts, of which coal-fired power capacity reached 1.01 billion kilowatts, accounting for 53%; The power generation is 4.45 trillion kWh, accounting for 64%.
With the challenges of carbon emission, environment and power generation cost becoming more and more severe, it is urgent for coal-fired power enterprises to find a feasible way to transform.
A few days ago, "Growing with the Republic — — The interview group of "New Media Entering New State-owned Enterprises" went to Taizhou Power Generation Co., Ltd., the national energy group, to see how this "garden power plant" did a good job in efficient and clean utilization of coal.
Built the world’s first million kilowatt ultra-supercritical secondary reheating project.
In the workshop of Taizhou Power Generation Co., Ltd., reporters saw two million kilowatt ultra-supercritical secondary reheat coal-fired units. One of them is the world’s first million kilowatt ultra-supercritical secondary reheat coal-fired generator set. The performance test shows that its power supply coal consumption is 265g/kWh, and its power generation efficiency reaches 47.82%, which is the best in the world.
"This equipment was jointly developed by Shanghai Electric and China Electric Power Consulting Group under the leadership of National Energy Group, which is 2 percentage points higher than the conventional primary reheating efficiency. "Chen Xuwei, general manager and deputy secretary of the Party Committee of Taizhou Power Generation Co., Ltd., National Energy Group, said. He further explained that an increase of 2 percentage points means that the coal used for generating primary electricity is 2 percentage points less. For example, the average coal consumption in our country is 300 grams per kilowatt-hour, and 2 percentage points means that 6 grams of standard coal is saved per kilowatt-hour. The higher the coal price, the better the economy of secondary reheating.
It is understood that the secondary reheating technology is promoted and implemented under the background of comprehensively improving the efficiency of energy conversion and utilization, implementing the strategy of energy conservation and emission reduction, reducing the total coal consumption and optimizing the coal consumption structure in order to cope with greenhouse gas emissions and alleviate environmental pressure in China, aiming at building a more efficient new generation of thermal power generating units.
At that time, there was no precedent for a million kilowatt secondary reheat unit in the world. "Face ‘ There is no overall scheme design, boiler, steam turbine and other major equipment, and no control system ’ ‘ Three noes ’ Problems and major challenges, we organize relevant units to address ‘ The key technology of million kilowatt secondary reheating ’ Joint research was carried out, and 15 major and technical schemes, such as overall technical scheme, boiler scheme, steam turbine scheme, spring base scheme, secondary reheat DCS control strategy, temperature regulation mode and bypass control technology, steam turbine shafting stability and start-up mode, were repeatedly demonstrated and reviewed to ensure that key technologies are advanced and reliable. " Chen Xuwei said.
After the two units were put into production, the third-party test showed that the coal consumption of power generation was nearly 6 g/kWh lower than the best level in the world today, and 14 g/kWh lower than the average level of domestic conventional one-time reheat units, and the power generation efficiency was 47.82% and 47.95% respectively. " In three research reports released in 2015-2016, the International Energy Agency commented that the secondary reheat unit of Taizhou Power Plant is currently the most efficient coal-fired unit in the world.
"According to our statistics, in recent years, 65% of the units in the whole East China and South China have adopted the secondary reheat technology in the projects under construction or design." Zhang Shishan, Party Secretary and Deputy General Manager of Jiangsu Electric Power Co., Ltd., National Energy Group, said.
Up to now, there are 21 secondary reheat units under construction or put into use in China. "We are more optimistic about ‘ Belt and Road ’ If you can go out, the prospect of this technology will be broader. " Chen Xuwei said.
Take the lead in exploring ultra-low emission path
The secondary reheat unit has not only made remarkable achievements in improving efficiency, but also reduced the emission of atmospheric pollutants by 5 percentage points compared with the conventional one million units every year, and achieved ultra-low emission of soot, sulfur dioxide and nitrogen oxides.
Standing at the height of the factory, you can see the white gas rising from two giant chimneys and gradually melting into the sky. "Out of the chimney, water vapor accounts for the majority. If we raise its temperature, we can’t actually see anything. The control of pollutant discharge is mainly in three aspects: sulfur dioxide, nitrogen oxides and soot. Our sulfur dioxide emission level is about 10 mg/m, and the national standard is 35 mg/m, and we are fully capable of reducing this level to a lower level; Nitrogen oxides, the national standard is 50 mg/m, and our average annual emission level is about 38-39 mg/m; Smoke and dust, the national standard is 10 mg/m, and our current average operating level is 2 mg/m, far superior to the national ultra-low emission level. " Chen Xuwei introduced.
It is reported that as early as 2012, at the beginning of the design of the secondary reheat unit, Taizhou Power Generation Co., Ltd. took the lead in proposing the ultra-low emission technical route of "six power plants+single tower double cycle+wet electrostatic precipitation", which was the first project in China to meet the gas emission standard.
Construct a full coverage governance system for unorganized discharge, air control, wastewater control and noise control; The coal yard is closed and reformed in the form of dry coal shed and windbreak and dust suppression net; Take the lead in building wharf shore power system to realize "zero emission" of generator air pollutants during the ship berthing … …
Taizhou company has always taken green environmental protection as the premise of its work and actively explored the road of green development.
100% comprehensive utilization of solid wastes
In addition, Taizhou Power Generation Co., Ltd. insists on turning waste into treasure, actively expands the sales channels of fly ash, slag and gypsum, and actively implements the deep processing of fly ash. The products such as fly ash, slag and gypsum sold are widely used in roads, high-speed rail, bridges and municipal construction, etc., to achieve 100% comprehensive utilization of solid waste.
According to Chen Xuwei, in recent years, the sales profit of heating and solid waste of Taizhou Power Generation Co., Ltd. accounted for more than 20% of the total profit of the enterprise. In 2018, the sales of ash is 87 million, gypsum is franchised by another company, and the price of first-class ash has reached 230 yuan/ton.
