Ecological water diversion method for treating water environment of Binjiang water body

Abstract

The invention discloses an ecological water diversion method for treating the water environment of the Binjiang water body. The method comprises the following steps: step 1, defining a watershed rangeas a research range; step 2, carrying out synchronous monitoring on the field hydrology-water quality; step 3, carrying out the generalization of a sewage discharge port; step 4, constructing a waterenvironment mathematical model, wherein the water environment mathematical model comprises a hydrodynamic model and a convection diffusion model; step 5, verifying the rate of the model; step 6, setting an improvement scheme; step 7, performing discussion and analysis on an obtained calculation result. According to the invention, based on the standard-reaching requirement of the water quality ofthe surface water, the water quality of the surface water is predicted based on the joint measures of the sewage interception for a small part of the directly discharged sewage and the ecological water supplement in the near future. Meanwhile, in the far future, the water quality of the surface water is predicted based on the sewage interception for most of the directly discharged sewage. In the near future, the directly discharged sewage of a certain proportion is connected into a sewage treatment system through a sewage connecting pipe. Meanwhile, the water quality of the surface water is enabled to reach the standard by combining the ecological water diversion means of the Binjiang water body. In the far future, most of the directly discharged sewage is directly connected into the sewage treatment system through deepening treatment. As a result, the water quality of the surface water can reach the standard.

Description

technical field [0001] The invention relates to an ecological water diversion method for improving the water environment of a riverside water body, and belongs to the technical field of water environment improvement. Background technique [0002] With the acceleration of urbanization in China, the population of large cities has increased rapidly, and the discharge of urban waste water has also increased rapidly, resulting in substandard surface water. Based on the demand for surface water quality to meet the standard, in the near future, the surface water quality will be predicted through the joint measures of direct discharge of sewage, a small part of sewage interception and ecological water replenishment; predict. [0003] Methods to control and improve urban water bodies include measures such as source control and pollution interception, and ecological water replenishment. Source control and pollution interception is to eliminate the pollution of waste water to the env...
