Embodiment Construction

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0039] Such as figure 1 As shown, a method for traceability of air pollutants for industrial parks, the method for traceability of air pollutants for industrial parks includes the following steps:

[0040] Step S1: collect observation data through monitoring points and judge exceeding standards;

[0041] In practical applications, a certain pollutant is found to exceed the standard: the excessive discharge of pollutants is detected by the installed sensors. ...

Abstract

The invention discloses a source-tracing method of atmospheric pollutants for an industrial park. The method comprises the following steps: collecting observation data by monitoring points and judgingwhether the observation data is out of limit or not; screening areas according to observation data out of limits; and obtaining observation data obtained by screening and collected in the areas and performing back calculations on a model according to a source position estimation model; obtaining a result and verifying the result. The source-tracing method has the following advantages: concentration data collected by a monitoring station around a diffusion source park is utilized to estimate source intensity magnitude and concrete positions of diffusion sources; and additionally, the method can be suitable for scenarios with variable source intensity and wind field data.

Description

technical field [0001] The invention relates to the technical field of traceability of pollutants, in particular to an industrial park-oriented method for traceability of atmospheric pollutants. Background technique [0002] At home and abroad, there are many studies on traceability methods of air pollutants, mainly focusing on nuclear proliferation. The traceability of air pollutants is generally used for the transportation and source analysis of conventional pollutants (especially PM2.5) in a large area. There are few studies on traceability analysis of air pollutants in small areas. In Rao SK (2007) Source estimation methods for atmospheric dispersion. Atmos Environ 41(33):6964–6973.doi:10.1016 / j.atmosenv.2007.04.064 (source estimation methods for atmospheric dispersion), the traceability algorithm is divided into forward and backward two categories. Forward methods usually use Bayesian inference to estimate diffusion sources, and backward algorithms directly solve the ...
