Problems solved by technology

Because this method is based on a 3×3 km grid, the accuracy is not detailed enough to effectively manage a large number of small, scattered, and random pollution sources, and the pollution process is ever-changing, which is closely related to meteorological factors such as wind direction, wind speed, and humidity. The method of human eye recognition by inspectors is not flexible and accurate enough

Abstract

The invention relates to a pollution source identification method and a system thereof. The pollution source identification method includes the steps that a monitoring area is divided into a pluralityof grids; monitoring devices are laid in the grids to establish a monitoring network; raw data are collected from the monitoring network, and the raw data include meteorological data, geographical data and pollution data; the suspected pollution source grid is determined by analyzing the raw data; and an air pollution diffusion model and original data are used for predicting the location of the maximum pollution concentration in the suspected pollution source grid.

Description

Technical field [0001] The present invention generally relates to the field of environmental monitoring, and specifically relates to a pollution source identification method and system. Background technique [0002] Atmospheric pollution refers to the phenomenon that the content of some substances in the atmosphere reaches a harmful level and even destroys the ecological system and the conditions for the normal survival and development of human beings, causing harm to people or things. Harmful gases such as ammonia, sulfur dioxide, carbon monoxide, nitride and fluoride discharged from human life or industrial and agricultural production can change the composition of the original air, cause pollution, cause global climate change, and disrupt ecological balance. [0003] Pollution sources refer to the sources of pollutants that cause environmental pollution, and usually point to places, equipment, devices, or human bodies that emit harmful substances or have harmful effects on the en...
