On May 23rd, the environmental monitoring data released by the Ministry of Ecology and Environment showed that this year 1-mdash; In April, the concentration of PM2.5 in the Beijing-Tianjin-Hebei region was 69 μ g/m3, down 18.8% year-on-year; The concentration of PM10 was 122 μ g/m3, a year-on-year decrease of 12.9%. Continuous improvement has become the main theme of air quality in this region.
The key points of governance are clear, and the management is becoming more and more sophisticated.
Industrial, coal-fired and motor vehicle emissions are the main sources of air pollutants in Beijing, Tianjin and Hebei and its surrounding areas, but the actual situation varies from place to place. Nearly five years after the implementation of the "Ten Atmospheric Articles", the air pollution control in Beijing, Tianjin and Hebei and its surrounding areas has changed from "grasping the eyebrows and beards" to refinement.
Last year, the central government allocated a financial fund of about 700 million yuan to start a special project on the causes and treatment of heavy air pollution, and formed 28 expert groups to go to "2+26" cities to carry out "one city, one policy" follow-up research, carry out refined source analysis, and put forward comprehensive solutions for urban air pollution prevention and control and regional overall solutions with strong operability, which provided strong support for refined haze control in various places. According to their own characteristics, all localities also clarify the key points of governance.
The latest round of PM2.5 source analysis released by Beijing recently shows that local emissions account for 2/3 of the main sources of PM2.5 in the whole year, while mobile sources such as motor vehicles account for the largest proportion of local atmospheric PM2.5 sources, reaching 45%.
Closely following the current changes in the sources and structure of air pollution, Beijing has made the treatment of high-emission vehicles a top priority, at the same time, it has expanded the low-emission area from the Sixth Ring Road to the whole city, and accelerated the elimination of "National III" heavy-duty diesel vehicles.
Since April 20, Beijing has implemented a closed-loop management mechanism for heavy-duty diesel vehicles, and no vehicles with excessive emissions will go through the formalities for entering Beijing. By the end of April, more than 10,000 cargo vehicles had been granted permits to enter Beijing, and 62 blacklisted vehicles were intercepted on the spot.
In Hebei, "scattered and polluted" enterprises are still a "cancer" that harms the air quality, and it is difficult to get rid of the roots and resurgence from time to time. Facing difficulties, we can work hard to create more blue sky! According to the requirements of the provincial party committee and the provincial government, the office of the leading group for air pollution prevention and control in Hebei Province mobilized all localities to carry out re-investigation, re-cleaning and re-rectification, demanding that no dead ends be left, both the symptoms and the root causes be treated, and at the same time, the combination of dredging and blocking and supporting the treatment should be carried out to effectively solve this chronic disease.
"Tianjin is a traditional industrial city, and its energy structure is biased towards coal. In addition, in winter, heating is a rigid demand, so coal cleaning has always been a key task of atmospheric control." Wen Wurui, director of Tianjin Environmental Protection Bureau, said that in 2017, Tianjin exceeded the annual task of cleaning and heating issued by the state. This year, it is proposed to "warm" and "blue sky" and strive to complete the "coal to gas".
Not only is the governance focus clear, the measures are promoted in an orderly manner, but the target management of improving the atmospheric environmental quality in Beijing, Tianjin and Hebei is also moving towards refinement. Taking Beijing as an example, the "Beijing Blue Sky Defence War 2018 Action Plan" has decomposed the annual pollutant concentration control indicators into all districts and counties. While implementing the project emission reduction, it needs benefits from management, highlighting the fine governance and the rule of law.
Responsibility is implemented at all levels, and strict accountability is unambiguous.
Not long ago, because the air quality improvement target set in winter was not completed, the main responsible comrades of the three municipal governments of Jincheng, Shanxi, Yangquan and Handan, Hebei, went to Beijing for an interview with the Ministry of Ecology and Environment, and their cities were also suspended from the environmental impact assessment of construction projects that added air pollutants.
If there is a goal and an assessment, there is a responsibility to investigate, which is nothing new in the prevention and control of air pollution in Beijing, Tianjin and Hebei in recent years.
In April 2017, the Ministry of Environmental Protection dispatched 5,600 environmental law enforcement officers from all over the country to carry out a one-year intensive supervision on the prevention and control of air pollution in "2+26" cities, and put forward a "five-step method" of supervision, assignment, inspection, interview and special supervision to conduct pressure at different levels.
At the end of February this year, some plastic enterprises in the jurisdiction failed to implement the peak production requirements of heating season and carried out production in violation of regulations, in accordance with the "Beijing-Tianjin-Hebei and surrounding areas 2017— Provisions on Quantitative Accountability for Comprehensive Control of Air Pollution in Autumn and Winter of 2018, Langfang City, Hebei Province gave administrative punishment to Comrade Yao Yuntao, deputy secretary of the county party committee and county magistrate who presided over the work of Wen ‘an County Party Committee and county government. This is the first accountability event after the implementation of the "quantitative accountability" system.
"There is a barbecue at the villagers’ activity station 50 meters west of the south gate of Jindi Community, a high-rise building in Liyuan Town", "The fumes from many restaurants on the southeast side of No.35, Zuojiazhuang Beili, Zuojiazhuang Street disturb the people" and "Lugouqiao Township Beijing Jingyuan Xincheng Catering Co., Ltd. has a direct discharge of fumes" … … Recently, the Beijing Municipal Environmental Protection Bureau interviewed the main leaders of 10 sub-district offices and township governments for these "small things", informed the existing problems, put forward rectification requirements, further transmitted environmental pressure to the grassroots, and urged the implementation of air pollution prevention and control measures.
The sources of air pollution are complex and diverse, and it is really not easy to manage them. The course of atmospheric governance in Beijing, Tianjin and Hebei has continuously proved that only by putting pressure in place and responsibility in place can the blue sky defense war be more successful.
Highlight joint prevention and control, and reduce and discharge benefits in a unified way.
Bai Zhiming, a Beijing citizen, thought that he could get a higher residual income by selling his national II car to neighboring provinces, but when he inquired, there was no place to pick up such a car in the surrounding areas. "I’m glad I can’t sell it, otherwise this high-emission tail gas may be blown back to Beijing from the surrounding area."
Bai Zhiming’s experience is a microcosm of the joint prevention and control of air pollution in Beijing, Tianjin and Hebei and its surrounding areas in recent years. Since April 1, 2016, Beijing, Tianjin and Hebei have unified the "National V" standard for motor vehicle emissions. There are still many such "unification".
Punch the "messy pollution" collectively. In the "2+26" cities of Beijing-Tianjin-Hebei air pollution transmission channel, more than 62,000 enterprises involved in gas "scattered pollution" have been investigated and rectified, which is estimated to contribute about 30% to the decline of PM2.5 concentration. To find the problem enterprises, timely clean up and rectify. On the one hand, this measure obviously improves air quality, and at the same time activates production factors at a deeper level, promotes the transformation and upgrading of traditional industries, and realizes win-win environmental, economic and social benefits.
Say "no" firmly to small boilers. In 2017, 56,000 small coal-fired boilers were eliminated in "2+26" cities, and 3.94 million "double-generation" cities were completed, replacing about 10 million tons of loose coal. A "coal-free zone" of tens of thousands of square kilometers will be built in Beijing-Tianjin Baolang.
Join hands to stop the heavy haze. At present, three-day accurate air quality forecast and seven-day potential analysis have been realized in the region, and the accuracy of pollution process forecast is close to 100%, and the accuracy of pollution level forecast is over 75%. According to estimates, the actual air quality pollution degree is reduced by 1-mdash compared with the predicted results by carrying out heavy pollution weather response; Two levels.
"Practice has proved that strengthening regional joint prevention and control is in line with the law of air pollution transmission and diffusion and mutual influence between regions, and it has grasped the crux of the problem and is very effective." Chai Fahe, deputy director of the National Joint Center for Air Pollution Prevention and Control and chief scientist of china environmental science Research Institute, said that although the overall air quality in the region has improved, the total amount of emissions is still large, and the situation is still grim. Only by reducing emissions jointly can we win more blue sky.
