How to take health precautions when air pollution enters a high incidence period in autumn and winte

Keep warm and pay attention to your diet.

First, reduce the emission of polluting gases, such as the desulfurization process on the factory, reduce dust emissions, etc.;

Second, take measures such as central heating to save energy and reduce pollutant emissions;

3. Plant more trees and afforestation, improve the underlying surface, and reduce wind and dust;

Fourth, encourage more public transportation to reduce energy waste and greenhouse gas emissions;

Fifth, regional coordinated control, air pollution is not a city's problem, and pollutants will be transported to its periphery under specific weather conditions. Wait a minute.

1. Rationally arrange the industrial layout and urban functional zoning.

The rational layout of industry should be fully considered in combination with urban planning. Industrial zones should generally be located at the edge of the city or in the suburbs, and should be located on the downwind side of the local maximum frequency wind direction, so that the exhaust fumes blow the residential area with the least number of times. Harmful industrial enterprises shall not be built in residential areas.

2. Strengthen greening.

In addition to beautifying the environment, plants also have the functions of regulating the climate, blocking, filtering and adsorbing dust, and absorbing harmful gases in the atmosphere.

3. Control coal pollution.

Using raw coal desulfurization technology, about 40% to 60% of inorganic sulfur in coal can be removed. Priority is given to low-sulphur fuels, such as low-sulphur coal and natural gas, which contain less sulphur.

The development of new energy, such as solar energy, wind energy, nuclear energy, combustible ice, etc., but the current technology is not mature enough, if it is used, it will cause new pollution, and the consumption cost is very high.

4. District central heating.

The establishment of large electric heating plants and heating stations for district central heating and heating, and the implementation of district central heating and heating, especially the thermal power plants and heating stations located in the suburbs, are very effective measures to eliminate smoke and dust for northern cities with dense low chimneys and heating in winter.

5. Treatment of waste gas from transportation vehicles.

Reduction of vehicle exhaust emissions. The main thing is to change the combustion design of the engine and improve the combustion quality of the oil, and strengthen traffic management. To solve the problem of automobile exhaust, it is generally necessary to install a catalytic converter to make the fuel fully burned and reduce the emission of harmful substances.

6. Chimney dust removal.

Sulfur dioxide control technology in flue gas can be divided into two categories: dry (using solid powder or granules as absorbent) and wet (using liquid as absorbent). The higher the chimney exhaust chimney, the more conducive to the diffusion and dilution of flue gas.

Air pollution and its deterioration not only endanger people's normal life, but also threaten people's physical and mental health. The following is the AA information compiled by Xuela, for reference only, welcome to read.

Prevention and control measures for air pollution (1) Adjust the industrial layout and industrial structure.

Unreasonable industrial layout is one of the main causes of air pollution in China's cities, and it is very necessary to improve the unreasonable industrial layout and rationally utilize the atmospheric environmental capacity. In adjusting the industrial layout, it is necessary to take ecological theory as the guide and comprehensively consider economic, social, and environmental benefits.

The readjustment of the industrial structure is to optimize the industrial structure with unified economic, social, and environmental benefits on the premise of ensuring the realization of the region's economic goals, eliminate backward processes and equipment that seriously pollute the environment, speed up technological transformation with energy conservation and consumption reduction, comprehensive utilization, and pollution control as the main contents, and adopt clean technology with a high technical starting point to control industrial pollution.

2) Improve the energy structure and actively take energy-saving measures.

Taking the opportunity of the country's west-to-east gas transmission and west-to-east power transmission, we will accelerate the adjustment of urban energy structure; By demarcating high-polluting fuel ban zones, we will promote the use of clean energy such as electricity, natural gas, and liquefied gas, reduce the consumption of raw coal in cities, promote clean coal technology, promote the development of cogeneration and central heating, and effectively control soot-type pollution. The principle of the "Technical Policy for the Prevention and Control of Pollution from Coal-fired Sulfur Dioxide Emissions" requires that the emission of coal-fired SO2 should be carried out with comprehensive prevention and control measures that combine energy conservation and rational use, coal quality, efficient and low-pollution combustion, and terminal treatment, and strict sulfur dioxide emission pollution control requirements according to the economic feasibility of the technology to reduce sulfur dioxide emissions. First of all, it is necessary to restrict the production and use of high-sulfur coal, encourage the use of high-sulfur coal for power plant boilers, large-scale industrial boilers and furnaces, and install flue gas desulfurization facilities (4)(5)(3)(3).

1. Afforestation is too old to serve.

2 Reduce the combustion of chemical fuels.

3. Install the automobile exhaust gas purification device.

4. The discharge of industrial exhaust gas should be purified.

1 Air pollution.

A more holistic concept, in a narrow sense, refers to the concentration of NO2, NOX, SO2 and PM10 in the air that greatly exceeds the natural value. In different functional areas, the indicators of comparison are also different (China is divided into three categories). The causes of formation vary depending on the specific contaminant.

For example: NO2 and NOx - car exhaust; SO2 – the use of high-sulfur coal; PM10 – Building Dust and so on. There are also additional parameters for different regions, such as Daqing (oil) – consider HC (hydrocarbons).

The method of prevention is to find the source of pollution corresponding to the pollutants and control them from the source; improved technologies (e.g. desulphurization and dust removal technologies); planting trees, increasing urban green coverage, and more.

2 Global warming.

It is mainly caused by various greenhouse gases covering the earth like a blanket, so that the hot gas cannot be released. Such as CO2, CH4, etc.

The way to prevent it is to reduce CO2 emissions.

3 The ozone hole over Antarctica.

It is the result of the decomposition of O3 by fluorinated compounds catalyzed by sunlight.

The prevention and control method is to reduce the use of fluorinated compounds (e.g. optimization of refrigerants).

4 White pollution.

It mainly refers to the pollution of polymeric compounds such as foam plastics, which are difficult to decompose due to the large molecular weight difference of these polymers and the strong intramolecular bonding effect.

The prevention and control method is to reduce the use of disposable lunch boxes, etc.

1 refers to polluted air.

2 refers to an increase in temperature.

3 is formed by atmospheric pollution.

4 refers to plastic bags.

Respiratory diseases, if inhaled some heavy metal substances in the body, such as lead, can also affect the nervous system.
