Trace method of pollution source in emergencies

Abstract

The invention provides a method for tracing pollution sources in emergency events. The method is characterized by comprising steps of 1, constructing source-quality response scene databases, to be more specific, creating fixed and mobile pollution source databases in certain ranges of river basins and hydrological scene databases of river basins where projects are located, simulating pollution statues of the project river basins due to pollutants of each pollution source under the conditions of different hydrological scenes and different emission amounts and creating the source-quality response scene databases in project regions; 2, carrying out source tracing analysis and computation, to be more specific, investigating and screening the pollution sources in the source-quality response scene databases according to feature information of the pollutants and hydrological regime information, finding out possible pollution sources which meet requirements of screening targets, constructing target libraries, analyzing pollution procedure fitting degrees of the target libraries, sorting the target libraries according to the fitting degrees, determining risk sources which possibly cause the emergency pollution accidents, and further conforming the risk sources by means of verification. The method has the advantage that the locations and the pollutant emission amounts of the pollution sources can be quickly determined by the aid of the method.

Description

technical field [0001] The invention belongs to the fields of environmental science, environmental engineering and environmental management; in particular, it relates to an engineering application method for tracking and tracing pollution sources of emergencies based on a source-mass response scenario database. technical background [0002] Sudden water pollution incidents in river basins are serious water environmental incidents that cause water environmental pollution, affect the normal functions of water bodies, and damage normal production and life. In reservoirs, lakes, rivers and other water bodies, the location of the discovery of water pollution incidents is usually not the source of water pollution. Carrying out source tracing of water pollution problems is an important part of cutting off the source of pollutants from the source for emergency response to sudden pollution incidents. In recent years, foreign scholars have carried out research on the traceability of w...

However, so far, the numerical calculation method for the inverse problem of mathematics and physics is still immature compared with the forward calculation, and when performing the inverse calculation, the calculation accuracy and calculation conditions are still important constraints that restrict its application in practical engineering. question
