Atmospheric pollution traceability diffusion analysis method and device

Abstract

The invention provides an atmospheric pollution traceability diffusion analysis method and device, and relates to the technical field of atmospheric pollution traceability. The method comprises the following steps: determining pollution sources according to an environment sensitive point and an upwind direction of a prevailing wind direction at the environment sensitive point, the pollution sources comprising a full-emission pollution source and a partial-emission pollution source; calculating the emission source intensity of pollutants emitted by the pollution source at the preset height of the pollution source; based on the local meteorological data of the pollution source, the sounding meteorological data of the city where the pollution source is located and the city topographic data, according to the emission source intensity, calculating the total ground concentration of environment sensitive points is obtained through a CALPUFF model; according to the total ground concentration of the environment sensitive points, determining the emission contribution rate of pollutants emitted by the pollution source to the environment sensitive points through a Gaussian diffusion model. According to the invention, the spatial precision of atmospheric pollutant emission monitoring can be improved.

Description

technical field [0001] The present application relates to the technical field of air pollution traceability, in particular to an air pollution traceability diffusion analysis method and device. Background technique [0002] At present, some air pollution diffusion analysis methods, based on the detection data uploaded by the environmental monitoring equipment deployed in the industrial park, can realize the real-time dynamic traceability of the polluting enterprises as the source traceability of the industrial park and the surrounding environmental sensitive points. It is mainly applicable to the dynamic traceability of horizontal diffusion. In practical applications, the pollutant gases emitted by most polluting enterprises diffuse in the vertical direction. Control the concentration of pollutants discharged by enterprises in industrial parks. Contents of the invention [0003] In order to improve the spatial accuracy of air pollutant emission monitoring, the present app...
