Atmospheric grid monitoring
is very popular because of its scientific nature
, which can effectively improve the efficiency of smog management and provide data for environmental supervision. According to the spatial layout of the entire area and the distribution of pollution sources, monitoring sites are arranged to form a grid, and the entire area is monitored in real time and dynamically to monitor the overall status and trends of air quality in the area in real time.
Appropriately increase the grid density in some sensitive areas of the region. For example, the major fixed sources of pollution, industrial parks, road traffic, urban and rural "small scattered" pollution re-emergence areas and other sources of emissions are monitored. Scientific assessments of the pollution status of organized and unorganized sources in the area and their impact on ambient air quality are conducted. influences. At the micro level, it can monitor the discharge of pollutants from pollution sources (such as construction sites, factories, etc.) and their impact on the surrounding area in real time; at the macro level, it can reflect the dynamic changes of air quality in the entire area.
Many researches and applications can be carried out using the data of atmospheric grid monitoring, including the analysis of pollution origin, cluster analysis, etc. So what are the specific application fields of atmospheric grid monitoring ?
1. Dust sources: Including soil dust and sand, construction sites, road dust and other emission sources;
2. Coal-fired sources: Including electric coal-fired, heating, industrial boilers, and urban and rural civil scattered combustion sources;
3. Motor vehicle sources: including various types of motor vehicle agricultural machinery, construction machinery and other emission sources;
4. Emission sources of volatile organic compounds: including petrochemical, chemical, surface coating, industrial enterprises using solvents, various types of oil storages, and emission sources of oil products at gas stations;
5. Other pollution sources: including sources such as straw burning, outdoor barbecue, and external transportation;
6. Particulate matter: including primary particles directly discharged from pollution sources and secondary particles generated by chemical reactions of pollutants discharged from pollution sources in the atmosphere;
7. Ozone: It is not a direct discharge pollutant. It is a secondary pollutant generated by photochemical reactions of nitrogen oxides, volatile organic compounds, and the like in the ambient air under the action of strong sunlight.
