Problems solved by technology

[0003] The PMF method and the ABB method are published particle source apportionment methods. The PMF method is suitable for source apportionment of single particle size particles. The particle size of the atmospheric environment is complex. Results; ABB did not include the particle size distribution index of the source identification components, which could not fully reflect the particle size distribution of the particle group

Abstract

The invention relates to an SDABB source apportionment method, a system, terminal equipment and a computer readable storage medium. The method comprises following steps: step one, collecting and analyzing atmospheric particulate pollution sources and identifying labeling components in the atmospheric particulate pollution sources; step two, calculating the particle size distribution of the labeling components; step three, collecting and analyzing the components of environmental particulate pollution sources; and step four, utilizing a three dimensional factor analysis model of multisource spectrum matrix nesting parallel factor analysis to calculate the concentration matrix of the environmental particulate components; substituting the particle size distribution of the labeling components obtained in the step two into the algorithm to obtain a source spectrum matrix and a source contribution matrix, identifying the sources, and quantifying the contribution of the sources. The provided method has the advantages that the particle size distribution of labeling components of atmospheric particulate sources is substituted into a three dimensional factor source apportionment algorithm, the obtained results are more accord with the physical meaning of particle size distribution of particulate sources, and the accuracy of source apportionment results is improved.
