An ecological management system of river biological hatching bed

Abstract

The invention relates to an ecological management system of a river channel biology hatching bed. The ecological management system comprises a river channel and a throttling dam. The throttling dam divides the river channel into an upstream section and a downstream section, and an overflowing opening is formed in the throttling dam. The ecological management system further comprises a reoxygenation region, the biology hatching bed, a biology hydrolysis canal and a sewage discharging region. The reoxygenation region is arranged at the downstream section corresponding to the overflowing opening, a reoxygenation facility is arranged inside the reoxygenation region, an outlet of the sewage discharging region is communicated with an inlet of the biology hydrolysis canal, an outlet of the biology hydrolysis canal is communicated with the reoxygenation region, an outlet of the reoxygenation region is communicated with an inlet of the biology hatching bed, and an outlet of the biology hatching bed is communicated with the downstream section. By the adoption of the technical scheme, microflorae inside the river channel can be enriched, a biology system inside the river channel can be improved, and the ecological food chain of the river channel can be perfected. Meanwhile, the ecological management system of the river channel biology hatching bed is high in restoration capacity, low in energy consumption, simple in management, high in controllability and capable of efficiently degrading water body pollution factors.

Description

technical field [0001] The invention belongs to the technical field of ecological management, and in particular relates to an ecological management system of a river biological hatching bed. Background technique [0002] Rivers are the blood of the earth. Purifying rivers will help improve the quality of the city and the living environment. In the initial stage of river management in my country, only the functions of flood control and drought relief, soil and water conservation and shipping were considered. With the development of the city and the improvement of the quality of life, river regulation began to focus on human and social effects. The governance models mainly focused on sewage interception, water diversion control, sediment dredging, and greening on both sides of the river. Solid waste and garbage, eliminate the dirty, messy and poor environment on both sides of the river, and mainly create a landscaped surrounding environment. A number of "riverside parks" bui...

AI Technical Summary

Problems solved by technology

[0005] The design structure of the traditional river channel for the biological food chain is relatively simple. Although the governance model has an ecological concept, it has not fully analyzed the overall biological chain, resulting in high operating costs, difficult management, poor controllability, and incomplete river flood control and drought relief facilities. , it is difficult to form a state of sustainable development, etc.
