A method for fast emergency calculation of maximum pollutant load exceeding standard in river of small watershed

Abstract

A method for fast emergency calculation of maximum pollutant load exceeding standard in river of small watershed is provided, which includes such steps as plotting the connection graph of flow rate, pollutant load and correspond proportion, calculating the maximum pollutant load of river in small watershed, calculating the maximum pollutant load of river in small watershed, calculating the maximumpollutant load of river in small watershed, calculating the maximum pollutant load of river in small watershed. (2) summarizing the actual load of pollutants entering the river within the accumulative monitoring period; 3) simultaneously calculating the maximum load of pollutants into the riv within the same period; (4) calculating the amount of pollutant reduction needed to enter the river, reducing the pollutant discharge of the polluting enterprises into the river or calculate the amount of water transfer, timely transfering water, and preventing the river reach from exceeding the standardof pollution, thereby realizing the river water environment protection. The method of the invention is novel, unique, easy to operate, accurate in measurement, and effectively solves the water environment protection of small watershed rivers (sections), and has remarkable economic and social benefits.

Description

technical field [0001] The invention relates to a fast emergency calculation method for exceeding the maximum load of pollutants in a small watershed river, in particular to a fast emergency calculation method for exceeding the standard of a small watershed river pollutant maximum load in a typical northern region. Background technique [0002] The typical characteristics of rivers in small basins in the north are the lack of natural runoff, and most of them are sewage rivers, which are mainly affected by the discharge of point source pollutants into the river. The water source of the river is mostly the tail water of the sewage treatment plant. On the basis of drawing lessons from the advanced experience of foreign river basin water environment management, my country's river basin management is becoming more and more systematic and refined, especially in the water environment management of large river basins. Although my country has established a relatively complete emergen...

Problems solved by technology

[0004] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide a fast emergency calculation method for the maximum load of pollutants in small watershed rivers, which can effectively identify the excessive pollutants in small watershed rivers, and diagnose the impact of small watershed rivers. Polluted river sections, quickly give emergency treatment measures for river pollutants in small watersheds, and realize water environment protection issues
