Sanitary protection of atmospheric air

Sanitary protection of atmospheric air - the complex of legislative, organizational and technical measures aimed at the protection of atmospheric air from harmful emissions.
One of the main causes of pollution of atmospheric air of harmful substances is the receipt of flue gases containing sulphur dioxide, soot, carbon monoxide, hydrocarbons, sulfur compounds, ash from the combustion of solid and liquid fuel in boiler plants, power plants, thermal power plants, industrial facilities, internal combustion engines (see the Smoke, Dust). The most significant sources of pollution are the enterprises of chemical and petrochemical industry, ferrous and nonferrous metallurgy, cement plants and other
Sources of air pollution in rural conditions can be mechanical and repair shops, livestock farm production processing of animals and food products. Air pollution can also occur in the processing fields of chemical substances: pesticides, herbicides, insecticides, defoliants and other, which are used to combat agricultural pests, weeds etc.,
The number of industrial emissions into the atmosphere of populated areas depends on many reasons: the production capacity, the availability of treatment facilities and their efficiency, technological process, frequency of emission, the height of tubes, meteorological conditions (speed, wind direction, humidity and other).
Sanitary atmospheric air protection includes the complex of measures on rational accommodation of productive forces, the layout of settlements (see), the development of technological schemes of production processes, eliminating or reducing to a minimum the harmful emissions into the atmosphere. Positive role in the improvement of the air basin of the cities plays gasification and electrification held at the national scale.
In order to reduce the harmful influence of industrial emissions on the health of the population and sanitary living conditions and life of the population of the sanitary legislation establishes the sanitary protection zone (see) between the source of pollution of atmospheric air of residential areas (SN 245 - 71).
For cleaning of industrial emissions of dust and ash applied pylepodavitel (dry and wet), electrostatic precipitators and a setup that produce mechanical and electrical cleaning. For trapping gases and vapors use scrubbers (hollow and with a nozzle), irrigated absorptive liquid, towards which moves be cleaned gas; barbacari - tanks for air purification, noise through a layer of absorption of a liquid, absorbers - tanks containing layer sorbent (activated carbon), through which bottom-up skipped gas being cleaned. Sanitary authorities shall exercise supervision over the operation of existing treatment plants through control over the degree of clearing of emissions and checking the correctness of technical magazine on the operation of treatment facilities. Terms of emissions of radioactive substances are regulated by the Sanitary rules of work with radioactive substances and ionizing radiation sources" № 333 - 60.
When sanitary inspection of sources of atmospheric pollution must take into account the character of production from the point of view of emission of harmful substances into the atmosphere, sanitary and topographic characteristics of the plant site, its size, the presence of the sanitary protection zone. Great importance is the predominant winds (see wind rose).
Total control over observance of measures of sanitary protection of atmospheric air is carried out sanitary and epidemiological service.
