Abstract

The invention discloses a method for predicting the influence of river sewage outlet arrangement in a plain river network area on river water quality. The method comprises the following steps: S1, constructing a river network hydrodynamic water quality coupling model; S2, determining predicted pollutants; S3, inputting the predicted pollutant information discharged from the river sewage draining exit into a river network hydrodynamic water quality coupling model; S4, determining a prediction range; S5, determining a prediction scheme for predicting the influence of pollutants on the river water quality; and S6, simulating the migration conditions of pollutants under different pollution discharge working conditions based on the established river network hydrodynamic water quality coupling model, and determining and predicting the influence distance of the pollutants on the river water quality. According to the invention, a river network hydrodynamic water quality coupling model is established. Main pollutants are selected as evaluation indexes, the space migration and transformation rule of discharged pollutants is described, the influence ranges of sewage discharge on the water quality under different working conditions are determined, and a basis is provided for analysis of the influence of arrangement of a river sewage draining exit on the river water quality and the water ecological environment.

Description

technical field [0001] The invention relates to a method for predicting the impact of the setting of sewage outlets in plain river network areas on river water quality, and in particular to a method for predicting the impact of setting sewage outlets in plain river network areas on river water quality by using a river network hydrodynamic water quality coupling model . Background technique [0002] The newly revised "Water Law of the People's Republic of China" proposes three new basic management systems in terms of water resource protection, namely, water function zoning, supervision and management of river discharge outlets, and protection systems for water sources. These three basic systems jointly build the basic framework of water resources protection supervision and management, which is in line with the actual situation of our country, and embodies the basic idea of ​​combining water resources quantity and quality, and combining functional requirements and protection r...
