Pollutant total amount control method based on control section water quality standard reaching

Abstract

The invention discloses a pollutant total amount control method based on control section water quality standard reaching. The pollutant total amount control method comprises the steps of carrying outdata collection, field investigation and monitoring; investigating and analyzing the pollution source current situation and the water environment quality current situation of the research area, and identifying a main pollution source and a main standard exceeding factor; constructing a nested river network hydrodynamic mathematical model and a water quality mathematical model; calibration is carried out according to the water quantity and water quality synchronous monitoring data; according to the pollution source investigation result and the model calibration result, calculating an allowabledischarge amount; providing a water quality improvement scheme. According to the method, a nested regional hydrodynamic water quality mathematical model is established by dividing a research region range and a calculation unit, the allowable discharge calculation research of the region is developed on the basis, and a water quality improvement scheme is provided, so that technical support and theoretical reference basis are provided for pollutant reduction and environmental improvement schemes.

Description

technical field [0001] The invention relates to the field of numerical simulation of the water environment, in particular to a method for controlling the total amount of pollutants based on the water quality of the control section reaching the standard. Background technique [0002] With the development of the economy and the growth of the population, the water consumption is increasing day by day. The shortage of water resources and the pollution of the water environment will gradually become the bottleneck restricting the economic development. The discharge of domestic sewage and industrial wastewater is increasing. The lag of construction has caused a series of problems such as direct discharge of urban domestic sewage, coupled with the impact of rural non-point source pollution and industrial point source pollution, resulting in periodic and seasonal water quality in some areas exceeding the standard, which requires our great attention. We need to carry out research on t...
