Problems solved by technology

However, when the contribution concentration of multiple pollutants in multiple areas in the study area is studied, the traditional "zeroing method" calculation needs to reset the simulation separately, which requires a large amount of calculation and is time-consuming. In addition, the diffusion of pollutants is accompanied by complex chemical reactions. , the sum of the contribution concentrations of each emission source is not equal to the contribution concentration of all emission sources, so the zeroing method will also lead to a certain error
In addition, some researchers use the ADMS model to calculate the relationship between pollutant emissions and air quality [Xiao Yang, Mao Xianqiang, Ma Genhui. Estimation and calculation of regional atmospheric environmental capacity based on ADMS and linear programming. Environmental Science Research, 2008, 21(3): 13 -16], but limited by the model, the research on the emission contribution of multiple pollutants in multiple regions requires a huge amount of calculation and is difficult to achieve

Description

technical field [0001] The invention relates to the technical field of air environment planning management and pollution prevention and control, in particular to an air pollution source classification method based on pollutant source identification technology. Background technique [0002] In recent years, with the deepening of air pollution control, and with the deepening understanding of pollution characteristics such as acid deposition, photochemical smog, and haze, the public has begun to realize the existence and seriousness of air pollution problems. my country's air pollution has changed from soot-type pollution to composite pollution where soot and motor vehicle exhaust pollution coexist. Atmospheric oxidation capacity continues to increase, and quite a few areas have faced severe situations where multiple regional pollutants coexist in high concentrations at the same time. This problem has not only become a serious environmental problem with Chinese characteristics,...
