Problems solved by technology

However, there are few studies on the river-inflow coefficient of pollution sources, and most of them refer to empirical formulas or survey methods to determine the river-inflow coefficient of pollution sources.
The pollution source inflow coefficient obtained by the above method has problems such as poor data accuracy, time-consuming, and uneconomical, etc., which affects the actual application calculation.

Abstract

The invention provides a method for calculating a river basin pollution source river entry coefficient based on a one-dimensional water quality model. The method comprises the steps of determining a river basin calculation range, and defining start and stop positions of upstream and downstream boundaries of a calculation area; collecting basin hydrological data and water quality data, and calculating pollution source emission statistical data in a regional range. Hydrological water quality data of upstream and downstream boundaries in the calculation area and emission data of pollutants in theregional range are obtained and substituted into an amphibious pollutant mass conservation equation, and a river entry coefficient of a basin pollution source can be calculated by utilizing a planning solving method. The model provided by the invention is simple in structure, and has the main characteristics of being simple and convenient, strong in operability and relatively high in simulation precision, and the river entering coefficient of a pollution source in the drainage basin can be well solved.

Description

technical field [0001] The invention specifically relates to a method for calculating the river basin pollution source inflow coefficient based on a one-dimensional water quality model. Background technique [0002] The pollutants that cause water pollution can be divided into point source pollution and non-point source pollution according to the source. Point source pollution refers to water pollution caused by industrial wastewater and urban sewage entering the sewage receiving body through fixed and monitorable sewage pipes. . Non-point source pollution, also known as non-point source pollution, refers to pollutants discharged from an uncertain location, which, with the help of precipitation and other effects, flow into the receiving sewage through processes such as surface runoff, soil erosion, and underground leaching. Non-point source pollution generally includes pesticides and fertilizers used in agriculture, feces and urine discharged from livestock and poultry bree...
