What are the methods to control smog?

First, improve air quality monitoring and establish an air quality release system and an early warning mechanism for heavy polluted weather. According to the actual situation, small ground air quality detection points are set up and equipped with mobile monitoring equipment to fully reflect the real situation of air quality and make preparations for air pollution control. Learn from the mature experience of weather forecast information release, establish an efficient air quality release system and early warning mechanism with the participation of radio stations, television stations, newspapers, internet and other forms of media, provide air quality information and early warning information of heavily polluted weather such as smog, and provide behavioral suggestions for people to travel and exercise according to the air quality.

Second, introduce emergency measures and establish a long-term mechanism to deal with serious air pollution such as smog. Formulate emergency plans for heavy air pollution, such as restricting bus travel, stopping polluting enterprises, sprinkling water in large yards to suppress dust, stopping work at construction sites, and stopping students' outdoor activities when heavy smog and heavy pollution weather occur.

Third, strengthen the control of dust. The results of scientific research show that the proportion of dust in the ambient air in many cities exceeds 25%. At present, there are many construction sites in towns (streets), and measures such as enclosure and dust prevention, vehicle sand washing and water spraying are not in place. It is suggested to strengthen the inspection, supervision and punishment of violations in construction sites, powder yards and other places and during transportation to reduce the harm of dust.

Fourth, further promote the rectification of the waste plastic industry. On the basis of comprehensive improvement of the waste plastics industry, we will continue to maintain a high-pressure situation on the waste plastics processing industry, establish a long-term supervision mechanism, and strengthen daily supervision to prevent the illegal processing of waste plastics from rebounding.

5. Strictly control heavily polluting industries. Strengthen the rectification of heavily polluting industries, and suggest using remote monitoring systems and other facilities to implement supervision, increase the inspection, supervision and punishment of violations, and strictly control pollutant emissions.

Six, strengthen the construction of public transport, reduce automobile exhaust emissions. Further strengthen the construction of public transport system, try out the hybrid power of bus and taxi, optimize the line design, extend the travel time and reduce private car travel. At the same time, it is also necessary to control the mass sales of private cars, actively manufacture, promote and sell electric environmentally-friendly cars, strengthen the environmental detection of automobile exhaust, and improve the qualified rate of automobile exhaust detection.

Seven, improve the assessment and supervision system. Establish an assessment system for air pollution control, improve the supervision system, confirm the main body of responsibility, and set the responsibility target; Establish a supervision and supervision system with the participation of competent departments, regulatory agencies, news media and the people, and form a situation in which the whole society participates in air pollution control.
