Air Pollution Control Methods

First, how to control air pollution, it is necessary to clarify the urban positioning, formulate urban planning scientifically, realize the rational distribution of urban population, optimize urban regional functions and industrial structure, promote the transformation of urban structure from heavy to light, and effectively reduce the burden on megacities. It is necessary to improve cities with over-concentrated population and industries, especially the “big city disease” caused by traffic congestion and environmental pollution caused by large cities, and strive to “relieve the burden” of cities. Urban planning should be formulated scientifically, the size of the urban population should be strictly controlled, the rational distribution of urban population should be guided, and the development environment should be improved. Properly promote the coordinated development of regions, decentralize some functions of the central city, optimize the industrial system and spatial layout, and transform from a production-oriented city to a service-oriented city.

Second, it is necessary to speed up the transformation of the development mode and the adjustment of the economic structure, strictly restrict high-emission industries, promote urban greening, and reduce the emission of air pollutants from the source. The increment should be actively controlled, and the stock should be optimized. In terms of increment, the environmental access threshold for industries with high energy consumption, high emission and overcapacity, such as thermal power, petroleum refining, organic chemical industry, steel, non-ferrous metals, cement, and building materials, should be further raised. On the one hand, it is necessary to strictly require the emission standards of industrial enterprises, intensify the technical transformation of the existing enterprises, further tighten the audit link of cleaner production, increase the inspection and punishment of key energy-consuming and polluting enterprises, and use “high standards and strict control”. The environmental protection management mechanism has forced enterprises to speed up technological innovation and industrial upgrading.

Actively encourage the development of strategic emerging industries, environmental protection industries and modern service industries, study and introduce subsidy policies for the purchase of new energy vehicles, and continuously optimize the industrial structure. Actively carry out urban greening construction, control the total amount of pollutant discharge, and effectively prevent and control air pollution. Plan and build an efficient, convenient, energy-saving and environmentally friendly transportation system to ease traffic congestion and reduce exhaust emissions. Develop smart transportation, improve the accessibility of urban traffic, and improve urban air quality by eliminating congestion.

Third, it is necessary to establish a more stringent environmental protection system, improve the air pollution monitoring, early warning and risk assessment mechanism, strengthen the construction of the environmental supervision system, and improve the air pollution response mechanism. It is necessary to effectively implement the newly revised “Ambient Air Quality Standards”, rationally arrange monitoring points, and strengthen the monitoring of fine particulate matter (PM2.5), ozone and other items. It is necessary to fully implement the emission permit system, and increase the emission reduction of air pollutants such as sulfur dioxide and nitrogen oxides.

It is necessary to strengthen the construction of an environmental supervision system, disclose environmental information, release air quality data in real time, and expand social supervision channels. In terms of monitoring capabilities, it is necessary to actively improve their own monitoring capabilities in accordance with the requirements of the new Ambient Air Quality Standards. It is necessary to establish a regional joint prevention and control mechanism to promote air pollution control, strengthen coordination and cooperation between regional organizations, establish and improve joint monitoring and joint forecasting mechanisms, and reduce the impact of external air pollution. It is necessary to promote the investigation and assessment of air pollution risks, and improve the management system focusing on prevention. It is necessary to do a good job in emergency management of air pollution, and constantly improve the emergency plan for heavily polluted weather.
