Abstract

The invention relates to a real-time analytic method for an atmospheric particle source. The method comprises the following steps: measuring target atmospheric particles by online and offline measurement methods respectively to obtain online and offline particle composition data, comparing and analyzing the online and offline particle composition data to form an online chemical particle composition time sequence after quantitative calibration, and analyzing the receptor sources of the target atmospheric particles by a PMF (Positive Matrix Factorization) model and a CMB (chemical mass balance) model respectively according to the known source spectrum data of the target atmospheric particles and the online chemical particle composition time sequence after the quantitative calibration to obtain particle source analysis results based on the PMF model and the CMB model; performing optimization grouping on the particle source analysis results based on the PMF model and the CMB model to obtain an optimized real-time atmospheric particle analysis result. The method can be widely applied to atmospheric particle pollution control.

Description

technical field [0001] The invention relates to a method for analyzing the source of particulate matter, in particular to a method for analyzing the source of atmospheric particulate matter in real time. Background technique [0002] At present, rapid economic development and energy consumption have brought great pressure to my country's atmospheric environmental governance. The problem of air pollution in my country is very serious. Among the traditional three pollutants (SO 2 , NO 2 , PM 10 ) is not effectively reduced, the PM 2.5 The concentration level of secondary pollutants represented by is rising rapidly. Since the revision of the National Ambient Air Quality Standard in February 2012, PM 2.5 It has become the primary pollutant that exceeds the standard of urban air quality in my country. [0003] To control particulate matter, the source of particulate matter must first be determined. Therefore, source analysis of atmospheric particulate matter has become an i...
