Description

technical field [0001] The invention relates to the technical field of atmospheric pollution source analysis, in particular to a method and device for analyzing atmospheric particulate matter pollution sources. Background technique [0002] At present, in order to study the impact of pollutants on the environment, the purpose of environmental governance and protection is generally achieved through the control of pollution sources. In order to achieve reasonable management and control of various pollution sources, the source apportionment method is mainly used to study and analyze the contribution of various pollution sources to each pollutant in the environment, that is, to analyze the source of each pollutant in the environment. [0003] However, the inventors found that the emission conditions of pollution sources, meteorological factors, and the transformation process or chemical reaction of pollutants in the atmosphere will affect the accuracy of pollution source analysi...

Problems solved by technology

[0003] However, the inventors found that the emission conditions of pollution sources, meteorological factors, and the transformation process or chemical reaction of pollutants in the atmosphere will affect the accuracy of pollution source analysis to a certain extent.

However, the source apportionment methods of the current receptor model methods such as the PMF model and numerical model methods such as the NAQPMS model do not pay attention to the above factors that affect the accuracy of source apportionment. Therefore, the source apportionment results of the current source apportionment methods are not accurate.

Due to the disadvantages of current source apportionment methods, in order to obtain accurate analysis results of pollution sources for various environmental pollutants, it is necessary to further subdivide pollution sources through researchers on the basis of current source apportionment results, in order to achieve refined pollutant source apportionment , this kind of refined source analysis method is more cumbersome and complicated
