Prevention and control technology of air pollutants, prevention and control measures of air pollutio

The prevention and control measures of air pollution are as follows:

1. Reduce pollutant emissions;

2. Strictly control the new production capacity of high-energy-consuming and high-polluting industries;

3. Vigorously promote cleaner production and vigorously develop public transportation;

4. Accelerate the adjustment of the energy structure and increase clean energy such as natural gas and coal-to-methane;

5. Strengthen the constraints of energy conservation and environmental protection indicators;

6. Implement a new mechanism for energy conservation and emission reduction with both incentives and constraints, increase the collection of sewage fees, strengthen international cooperation, and vigorously cultivate environmental protection and new energy industries;

7. Use laws and standards to "force" industrial transformation and upgrading;

8. Construct a responsibility assessment system for atmospheric environment remediation targets in various provinces (autonomous regions and municipalities);

9. According to the pollution level, take measures such as limiting production and emissions of heavily polluting enterprises and restricting the movement of motor vehicles in a timely manner;

10. Establish a code of conduct for the whole society to "breathe together and work together", and mobilize the whole people to participate in environmental protection and supervision.

Law of the People's Republic of China on the Prevention and Control of Air Pollution

Article 30. Enterprises, public institutions, and other producers and operators violating the rulesLaws and RegulationsWhere the discharge of air pollutants causes or may cause serious air pollution, or relevant evidence may be lost or concealed, the competent departments of ecology and environment of the people's governments at or above the county level and other departments responsible for the supervision and management of atmospheric environmental protection may take administrative compulsory measures such as sealing and seizure of relevant facilities, equipment, and articles.

The first is to reduce pollutant emissions. The second is to strictly control the new production capacity of high-energy-consuming and high-polluting industries. The third is to vigorously promote cleaner production. Fourth, accelerate the adjustment of the energy structure and increase clean energy such as natural gas and coal-to-methane. Fifth, strengthen the constraints of energy conservation and environmental protection indicators.

(1) Reduce combustion. central heating, limiting the number of cars, and putting an end to the burning of firecrackers, especially the fireworks and firecrackers of government agencies and units are the first to be solved;

2) improve refrigeration technology and limit the use of freon refrigerants;

3) Governance of corruption and implementation of environmental management. Turning fines into governance;

4) Limit indiscriminate felling and exponential afforestation.

2. Legal basis:

Article 2 of the Law of the People's Republic of China on the Prevention and Control of Air Pollution.

To prevent and control air pollution, the goal should be to improve the quality of the atmospheric environment, adhere to the source control, plan first, change the mode of economic development, optimize the industrial structure and layout, and adjust the energy structure. To prevent and control air pollution, comprehensive prevention and control of air pollution such as coal burning, industry, motor vehicles and ships, dust, and agriculture shall be strengthened, joint prevention and control of regional air pollution shall be promoted, and coordinated control of air pollutants and greenhouse gases such as particulate matter, sulfur dioxide, nitrogen oxides, volatile organic compounds, and ammonia shall be implemented.

2. The harm of air pollution to human health.

A person needs to breathe air to stay alive. An adult breathes about 20,000 times a day and inhales 15 20 cubic meters of air. Therefore, polluted air has a direct impact on human health.

The harm of air pollutants to the human body is multifaceted, manifested as respiratory system damage, physiological dysfunction, digestive system disorders, nervous system abnormalities, mental decline, carcinogenesis, and disability. The smoke of this catastrophe is known as the "smoke of murder." When the concentration of pollutants in the atmosphere is very high, it can cause acute pollution poisoning, or worsen the symptoms, and even kill thousands of people in a few days.

In fact, even if the concentration of pollutants in the atmosphere is not high, the human body breathes this polluted air for many months, which can cause diseases such as chronic bronchitis, bronchial asthma, emphysema and lung cancer.

1. The main methods of solid particulate matter are: gravity sedimentation, cyclone dust removal, inertial dust removal, electrostatic precipitator, bag dust removal, wet dust removal, venturi dust removal, etc.

2. For automobiles, the reduction treatment is mainly carried out by three-way catalyst; In most cases, flue gas denitrification is based on absorption-oxidation technology, such as electron beam irradiation, plasma technology, etc. However, at present, it is mainly by controlling the combustion temperature of the boiler and other combustion conditions (mainly in terms of the supply of combustion air).

3. CO and hydrocarbons, mainly through full combustion and catalytic oxidation to deal with large-scale low-concentration pollutant gases; At the same time, there are also methods of absorption and adsorption.

4. Heavy metals are removed by cooling and dust removal facilities.

5. Ozone (secondary pollutant) is mainly controlled by controlling and reducing the concentration of hydrocarbons in the air and NOx.

6. Radioactive gas (radon gas), ventilation technology is the most effective control technology at present.

The prevention and control measures of air pollution are as follows:

1. Reduce pollutant emissions;

2. Strictly control the new production capacity of high-energy-consuming, high-disturbance and polluting industries;

3. Vigorously promote cleaner production and vigorously develop public transportation;

4. Accelerate the adjustment of the energy structure and increase clean energy such as natural gas and coal-to-methane;

5. Strengthen the constraints of energy conservation and environmental protection indicators;

6. Implement a new mechanism for energy conservation and emission reduction with both incentives and constraints, increase the collection of sewage fees, strengthen international cooperation, and vigorously cultivate environmental protection and new energy industries;

7. Use laws and standards to "force" industrial transformation and upgrading;

8. Construct a responsibility assessment system for the atmospheric environment remediation targets of various provinces (autonomous regions and municipalities);

9. According to the pollution level, take measures such as limiting production and emissions of heavily polluting enterprises and restricting the movement of motor vehicles in a timely manner;

10. Establish a code of conduct for the whole society to "breathe together and work together", and mobilize the whole people to participate in environmental protection and supervision.
