Method for calculating tracing contribution of sudden accidental water pollution source at a point source

Abstract

The invention relates to a method for calculating the tracing contribution of a sudden accidental water pollution source at a point source, which is effective in rapid tracing of a river basin and environmental management and protection of the river basin. The method includes: according to the natural geographical features of the river basin, determining the control area corresponding to the control section of the river basin; using the monitoring data of the pollution source and the statistical data of the pollution source to budget regarding the pollution source in the river basin; using a one-dimensional unsteady water quality model to establish the relationship between pollution source and water quality of the section; using the relationship between pollution source and water quality of the section to calculate the contribution coefficient of the pollution source within the river basin and characterizing the contribution of pollution sources. The method is novel and unique, easy tooperate and use, accurate in calculation, and high in efficiency, makes full use of the basic information of the existing pollution source, quickly feeds back the state of the pollution source in theriver control section in a short time, locks the pollution source which has relatively greater contribution to the river water quality in the river basin, provides the support for the pollution tracing of the river basin, and is effectively used for the environmental protection and treatment of the river.

Description

technical field [0001] The invention relates to the environmental protection of river basins, in particular to a method for calculating the contribution degree of point source sudden water pollution source accident traceability. Background technique [0002] Water is the source of life and the primary basis for maintaining the sustainable development of the ecological environment. With the advancement of industrialization and new urbanization, the water environment in my country's river basins is facing new challenges. Water pollution incidents occur frequently, which poses a threat to river water quality and People's health is a threat. Therefore, it is very important to quickly and accurately grasp the relevant information of pollution sources for emergency disposal. [0003] At present, scholars at home and abroad have studied a variety of river water pollution accident traceability algorithms, which can be roughly divided into the following categories: one is to infer po...

Problems solved by technology

[0004] The existing methods have their own advantages and disadvantages, but the problem is that due to the technical problems of the method itself, when dealing with the source tracing of sudden pollution incidents, it will lead to a large workload of pollution source tracing, which consumes a lot of time and energy, and cannot be carried out in a timely and effective manner. The work of investigation and traceability affects the management and governance of the river basin, and is not conducive to the protection of the river environment. Therefore, there has been no public report on how to provide a calculation method for the contribution degree of point source sudden water pollution source accident traceability.
