Method for accurately positioning pollution source by using accumulated dust and raised dust

Abstract

The invention discloses a method for accurately positioning a pollution source by using accumulated dust and raised dust. The method comprises the steps: obtaining road dust load data SL and road raised dust data, uploading the data to a cloud platform through a central control module, and building a road raised dust-accumulated dust space-time database; obtaining a raised dust multi-channel particulate matter particle size spectrogram a and a dust retention multi-channel particulate matter particle size spectrogram b, uploading data of a and b to a cloud platform through a central control module, and establishing a raised dust-dust retention multi-channel particulate matter particle size spectrogram space-time database; according to the flying dust-accumulated dust multi-channel particulate matter particle size spectrogram space-time database, judging the correlation between road accumulated dust and flying dust, and judging the correlation between the flying dust and the flying dust total type library, and deducing the flying dust pollution type; determining a pollution source according to the positioning information in the road dust raising-dust retention space-time database. According to the invention, the flying dust pollution emission source can be rapidly, accurately and efficiently judged. The method is high in temporal-spatial resolution, and can be directly used for work guidance of air pollution prevention and air quality fine management.

Description

technical field [0001] The invention relates to the field of sanitation, in particular to a method for accurately locating pollution sources by utilizing accumulated dust and flying dust. Background technique [0002] In order to further improve the ambient air quality and reduce the impact of road dust pollution on environmental quality, it is necessary to trace the source of dust pollution scientifically and effectively. At present, the research on dust traceability is mainly based on the monitoring of particle concentration and the production of pollution discharge inventory, but the monitoring of particle concentration cannot judge the specific type of dust pollution, and has little guiding effect on dust traceability; the compilation of emission inventory also has heavy workload, high cost, and representative disadvantages such as poor performance and low accuracy. [0003] The invention provides a method for quickly analyzing the type of dust and accurately locking th...
