Recently, Hebei, Jilin, Shaanxi and other places have successively deployed comprehensive air pollution control work in 2018. Among them, Hebei clearly clarified the target value of major pollutants in the year; Shaanxi listed iron smog as the number one environmental protection project. According to data from the Ministry of Environmental Protection, in the past two years, under the comprehensive management of various departments, air pollution prevention and control has achieved phased effects, and various air quality improvement targets have been fully realized. Experts pointed out that the next step is to speed up the adjustment of industrial structure, energy structure and traffic structure, and fundamentally solve the problem of frequent air pollution in Beijing-Tianjin-Hebei and surrounding areas.

Multi-ground control of spring air pollution prevention and control work

At the end of February, Hebei Province held a meeting on comprehensive management of atmospheric pollution. In 2018, Hebei will highlight the comprehensive control of air pollution in key areas, deepen the adjustment of industrial structure, energy structure and transportation structure, improve the monitoring and control system, and strengthen the building of environmental protection at the grassroots level. Strengthen law enforcement inspections and special inspections to promote continuous improvement of the province's air quality. The goal is that the average concentration of fine particulate matter (PM2.5) in the province in 2018 will be reduced by more than 6% from 2017 to 61 μg/m3.

For specific work deployment, Hebei Province requires all levels of departments to do a good job in top-level design, formulate a three-year operational plan and a “guarantee bottom line, retreat ten” concentrated attack plan; do a good job in coal-fired pollution control, promote clean heating; Prevention and control, resolutely go to production capacity, pay close attention to the "disintegration" enterprises and key industries rectification; do a good job in pollution prevention and control in the transportation sector, speed up the adjustment of freight structure; accurate emergency reduction, the maximum degree of "shrinking time peaks." At the same time, we must strictly implement the responsibility, strengthen supervision and law enforcement, and seriously assess accountability to ensure the successful completion of the annual target tasks.

Prior to this, Shaanxi Province held an iron fist treatment conference. The meeting stressed that it is necessary to firmly establish and practice the concept of “green water and green hills are Jinshan Yinshan”, and to include iron fists to promote smog control in the number one project of environmental protection. Shaanxi Province proposed that the iron fist cure is the bottom line task to promote high quality development. The province must conscientiously implement the three-year action plan for the blue sky defense war, and adhere to the "six strategies" of reducing coal, controlling vehicles, suppressing dust, treating the source, prohibiting the burning, and increasing the green, and putting all tasks into practice. Strictly ensure the entry of projects, do a good job in energy conservation and emission reduction, strengthen afforestation, promote industrial transformation and upgrading, develop clean production, promote green lifestyles, and promote the continuous improvement of the province's air quality.

In addition, the Environmental Protection Bureau of Changchun City of Jilin Province recently requested the environmental protection departments at all levels in the city to further strengthen the control over the prevention and control of air pollution in the spring, and adopt effective measures such as daily punishment, seizure and seizure, production restriction, and administrative detention, and increase the number of enterprises. Investigate and punish illegal discharges such as smuggling and super-discharging, and effectively improve the quality of the city's spring atmospheric environment. At the same time, clear the list of key inspection companies under the division of responsibilities and early warning of heavy pollution, and check the implementation of tasks. Further strengthen the real-time monitoring of all online data to ensure the normal operation of pollution prevention facilities.

Air pollution control has entered a critical period

At the end of February this year, the Ministry of Environmental Protection held a regular press conference to introduce the progress of air pollution prevention and control work. Liu Bingjiang, director of the Department of Atmospheric Environment Management of the Ministry of Environmental Protection, said that since the implementation of the "Air Pollution Prevention Action Plan" (referred to as "Atmosphere Ten"), the national air pollution prevention and control has made progress in stages, the overall air quality has improved, and the key areas have improved significantly.

Specifically, as of the end of 2017, the concentration of PM10 in cities and above in the country decreased by more than 10%; the concentration of fine particulate matter (PM2.5) in the Beijing-Tianjin-Hebei, Yangtze River Delta and Pearl River Delta regions decreased by 25%, 20%, 15% or so. The air quality improvement targets identified in the "Atmosphere Ten" are fully realized.

Liu Bingjiang said that the system of air pollution prevention and control has been initially established nationwide. The governance structure of the joint management is initially established, the decomposition tasks are refined, the responsibilities are layered, and the annual assessment is implemented. At the same time, central environmental protection inspections were carried out in 31 provinces (autonomous regions and municipalities); and intensive inspections on “2+26” urban air pollution prevention and control were carried out. Party and government have the same responsibility and responsibility, and they have been effectively and effectively implemented.

Second, the regional joint defense joint control achieved major innovation. Establish a coordination mechanism for air pollution prevention and control in key areas such as Beijing-Tianjin-Hebei and Yangtze River Delta, break the boundaries of administrative divisions, and focus on solving the worldwide problem of long-distance transmission of atmospheric pollution and mutual influence between regions.

In addition, the environmental rule of law guarantees more powerful. The Law on Environmental Protection and the Law on Prevention and Control of Atmospheric Pollution have been revised and promulgated successively, and law enforcement means such as daily punishment, production stoppage, seizure and seizure are more abundant. By organizing special law enforcement inspections for air pollution prevention and control, environmental violations such as excessive discharges have been curbed.

Adjust energy structure and industrial structure

Liu Bingjiang pointed out that at present, China's ambient air quality is generally better in the national scope and average level, the key areas have improved significantly, and the prevention and control of air pollution has made significant progress in stages, but compared with the needs of the people's growing and beautiful ecological environment. Big gap. First, the problem of heavy air pollution in some areas and parts of time is still outstanding; second, regional progress is unbalanced, and work in some areas is relatively lagging; third is coal-based energy structure, industrial structure dominated by heavy chemicals, and road goods. The transportation structure based on transportation has not changed, and the discharge of pollutants is large. The overall situation of air pollution prevention and control in China is still grim.

In response to the next step, Liu Bingjiang said that the Ministry of Environmental Protection will, in accordance with the requirements of the party's 19th National Congress and the Central Economic Work Conference, thoroughly summarize the implementation of the "Atmosphere Ten" and formulate a three-year combat plan to win the blue sky defense war. Clarify specific campaigns, timetables and roadmaps, focusing on key areas such as Beijing-Tianjin-Hebei and surrounding areas, the Yangtze River Delta, etc., focusing on superior strength, strengthening regional joint defense joint control, and one battle and then one battle to ensure greater success in three years. Results.

Specifically, in terms of adjusting the industrial structure, it will comprehensively promote the “disintegration” enterprises and clusters to comprehensively rectify, integrate all fixed pollution sources into environmental supervision, comprehensively install online monitoring of all key industrial pollution sources, and clarify enterprises with uncertified emissions and emissions. In the end, the time limit will be corrected. Implement special emission limits for atmospheric pollutants in key areas to achieve deep treatment. Major projects for ultra-low emission transformation in the steel and coking industries.

In terms of accelerating the adjustment of energy structure, the coal-burning units with heavy pollution will be eliminated and the supply of clean electricity will be increased. In key areas, we will increase the protection of natural gas and electricity supply, and significantly reduce the total consumption of coal terminals.

In the area of ​​heavy pollution weather response, the air quality forecasting and forecasting system will be further improved, and the six regional air quality forecasting and forecasting centers will be promoted to form capacity and function as soon as possible. Improve the emergency plan for heavy polluted weather, optimize the start-up standards, compact the emergency emission reduction list measures, implement regional emergency response, and strive to reduce the time of heavy pollution.

Chai Fahe, chief scientist of the atmospheric environment of the Chinese Academy of Environmental Sciences, pointed out that in the prevention and control of heavy pollution, on the one hand, it is necessary to speed up the adjustment of industrial structure, energy structure and traffic structure, and fundamentally solve the atmosphere of Beijing-Tianjin-Hebei and surrounding areas. On the other hand, we must actively study the air quality situation and take effective measures to reduce the impact of heavy pollution.
