Pollution source tracing method

Abstract

The invention relates to a pollution source tracing method. The method comprises the steps that a vector A is formed by taking an initial pollution source as a starting point and taking the reverse direction of a wind direction in a domain of the initial pollution source as a direction, a sub-grid group B intersected with the vector is acquired through the vector, after the sub-grid group B is acquired, sub-grid regions of which the pollutant concentration is greater than a preset value is screened, and a sub-grid group C is formed by the sub-grid regions; if the sub-grid group C is an empty set, namely, the number of sub-grid regions in the sub-grid group C is zero, namely, no pollution source exists in the headwind direction of the initial grid, it can be judged that the initial pollution source in the initial grid is the pollution source, otherwise, reverse tracing is sequentially conducted on the sub-grids in the sub-grid group C according to the reverse direction of the vector A through the reverse tracing method until the pollution source in a to-be-detected region is found. Compared with an existing traceability method, the method is simple and effective, the traceability accuracy is high, electronic expression can be easily carried out through a computer system, and the traceability efficiency is high.

Description

technical field [0001] The invention relates to a source tracing method, in particular to a pollution source tracing method. Background technique [0002] With the improvement of environmental protection requirements, the regulatory authorities have gradually increased the monitoring and traceability of various pollutants. The existing traceability method is mainly to trace the source through manual monitoring, which is less efficient due to the increasing concealment of pollution sources. In order to improve the traceability efficiency, some pollutant traceability systems have emerged to realize automatic monitoring and traceability of pollution sources. However, the existing pollutant traceability systems use relatively complicated algorithms, and generally do not combine meteorological data to trace pollution sources. It makes it impossible to timely and accurately intelligently identify and locate the source of the odor, and even produce false positives and false negati...
