New measures for prevention and control of atmospheric pollution in North China The rapid expansion of urban scale in North China, the rapid development of urban agglomerations, the large concentration of heavy industries such as steel, coking, petrochemicals, and the rapid increase in vehicle ownership have resulted in a high concentration of pollutants in this region. . In addition, many cities in North China such as Beijing, Shijiazhuang, Xingtai and Handan are located in the piedmont plain of Taihang Mountain. The specific geographical location makes the meteorological conditions that are not conducive to the spread of pollutants appear frequently, thus causing the continuous occurrence of haze pollution. In order to promote the prevention and control of air pollution in North China and improve regional air quality, the countermeasures and suggestions are as follows:
First, transformation and upgrading, and promote structural adjustment.
In order to combine the actual industries of steel and cement in North China and the heavy industrial structure, on the one hand, increase the promotion of industrial transformation and upgrading, eliminate backward production capacity and retain advanced production capacity; on the other hand, increase industrial restructuring and resolutely curb production capacity. Excessive and backward production capacity projects were launched. In this regard, Dongguan environmental protection people reminded that we must effectively promote the elimination of backward production capacity and prevent the slogan-style production capacity from being eliminated. The North China region should base itself on a national chess game and jump out of North China to see North China, focusing on the transformation and upgrading of backward industries such as steel, cement, electrolytic aluminum and coking, and the elimination of backward production capacity. Second, it is necessary to strengthen control over new production capacity and make assessments, which are not in line with national industries. The policy must be resolutely stopped, blocking the increase in backward or excess capacity from the source.
Second, based on the actual, reduce coal consumption.
The North China region is not only a coal-producing and coal-consuming area, but also a hard-hit area with smog weather. The pressure on air pollution prevention and control is enormous. At the same time, there is not enough water, nuclear energy and other energy sources in North China to replace coal. For this reason, it is necessary to reduce coal consumption based on actual conditions in the region.
1. Strictly control the increment and total amount of coal. On the basis of resolutely not adding new coal consumption, the total coal consumption will be reduced by increasing new energy substitution and improving coal combustion efficiency; 2. Forming scale effect. It is necessary to increase the integration of coal-fired power generation projects, and to close large and large units to form large units. In this way, on the one hand, it can form scale effect, on the other hand, it is also conducive to the implementation of desulfurization and denitrification treatment; the third is to increase government subsidies, subsidize enterprises that implement coal-fired substitution and coal-fired treatment, and use it for rural winter heating. Coal is subsidized to provide clean coal and briquette.
Third, coordinate linkages and give full play to joint efforts.
The prevention and control of air pollution in North China is a game of chess. It must be based on the overall situation of the region and form a combination of governance to achieve the goal of prevention and control.
1. Dongguan environmental protection experts reminded that under the unified coordination and guidance of the Ministry of Environmental Protection, we should solve the problem of air pollution in the region and unify the prevention and control measures to ensure that the targets of air pollution prevention and control in the region are unified, the strategies are synchronized, information is shared, and air pollution is formed. The synergy of governance.
2. When formulating goals and work plans, focus on the overall situation of the region while focusing on the overall situation of the provinces, achieve the goal of regional prevention and control, and achieve a game of prevention and control, and reverse the embarrassing situation of the current war.
3. It is clear that the people's governments at all levels are responsible for the prevention and control of air pollution, and all relevant departments, including the environmental protection department, are responsible for the decomposition of responsibility, and they must perform their duties and responsibilities.
4. To achieve air pressure enforcement and iron accountability for air pollution prevention and control, and form a high-pressure situation against environmental violations. It is necessary to fully leverage the "two high" judicial interpretation to severely punish environmental violations and form a powerful shock.
5. Realize information sharing and do a good job in emergency warning. Establish an information reporting mechanism for key enterprises related to gas in North China, establish a regional air quality monitoring network, and an information exchange and management system, prepare and improve emergency plans, and establish a consultation mechanism.
Fourth, propaganda and guidance, create an atmosphere.
Governments at all levels should vigorously carry out publicity and education on air pollution prevention and control, scientifically popularize knowledge on prevention and control of air pollution, and let the public fully understand the current situation, progress and difficulties faced by air pollution prevention, and mobilize and guide the public to participate in and supervise air pollution control. To strengthen effective communication with the media, we must give full play to the role of public opinion guidance and supervision of the news media, as well as take the initiative, pass positive messages through the media, and create a public opinion environment conducive to the work.
