Watershed sudden water pollution rapid tracing method

Abstract

The invention relates to a rapid tracing method for sudden water pollution of a drainage basin. The method comprises the following steps: obtaining the distribution of a potential pollution source area of a water pollution source; monitoring water quality components in the potential pollution source area; pollutants exceeding the highest allowable discharge concentration of the comprehensive sewage discharge standard or higher than three times of background values are selected as composition characteristic pollution factors; building a traceability model; calculating a risk sensitive area of the polluted water flow source probability in real time; and counting the pollutant concentration in the risk sensitive area and the contribution of each industry to the pollutant concentration in a drain outlet discharge list. According to the method, the water pollutant concentration of the drainage basin and the contribution of each pollution discharge point in the list to the pollutant concentration of the risk area of the drainage basin can be accurately simulated, the water environment quality of the drainage basin can be effectively monitored, the problem of excessive pollution dischargeof a key pollution discharge port is solved, the calculated amount is small, and a traceability result can be quickly obtained.

Description

technical field [0001] The invention belongs to the technical field of water environment management, and in particular relates to a rapid source tracing method for sudden water pollution in a river basin. Background technique [0002] The time and place of sudden water pollution accidents have great uncertainty, and it is also difficult to determine the way and degree of harm, which will easily lead to the failure of normal operation of social life and production order, and cause serious damage to the water system and ecological environment. pollution and injury. It is necessary to find effective and reliable pollution source traceability methods, quickly and accurately find out the time and location of pollution sources that lead to sudden water pollution, and make correct preventive measures and first aid decisions. [0003] The pollution source traceability methods that have been proposed so far include genetic algorithm-based methods, water quality model-based methods, ...
