A method to solve the poor flow of water bodies in urban agglomerations

Abstract

The invention relates to a method for solving unsmooth flow of city agglomeration water bodies. According to the method, at least two stages of control guide weirs are arranged in the water flow direction at the water inlet side of a dead angle area of the water flow, a plurality of flow guide channels with gradually decreasing inner diameter in the water flow direction are arranged in the controlguide weirs, a water-permeable dam body with a trapezoidal longitudinal section is arranged on the downstream side of the last-stage control guide weir, and a plurality of rows of submerged plants are arranged downstream of the water-permeable dam body in the water flow direction, so that layer-by-layer diversion of the water flow is achieved; a water flow path is re-planned, so that the problemof unsmooth water flow generated under the conventional water flow condition is thoroughly solved, and the water flow dead angle environment pollution and the landscape effect are remarkably improved;and energy is saved, and the water flow direction and the flow rate can be efficiently guided and controlled, so that a water area in a water flow dead angle area fully flows, on one hand, the waterflow can be dredged, the flow rate can be stabilized, and on the other hand, the water quality can be purified once again.

Description

technical field [0001] The invention relates to the fields of river and lake water ecology and water environment management, in particular to a method for solving the problem of poor water flow in urban agglomerations. Background technique [0002] Urban water bodies are not only beautiful and pleasant landscapes, but also play a role in regulating floods, protecting biodiversity, maintaining ecological balance, preserving fresh water resources, supplementing groundwater, and regulating climate. They have good ecological, social, economic, and environmental benefits. benefit. Due to the poor fluidity of water bodies, urban water bodies have the characteristics of relatively simple aquatic ecosystems, relatively small water environment capacity, and poor self-purification ability of water bodies, resulting in a rather fragile ecological environment. If the pollution load exceeds the self-purification capacity of the water body, it will easily cause the reduction of aquatic a...

AI Technical Summary

Problems solved by technology

Conventional water diversion measures used to purify water bodies and increase fluidity mainly rely on artificial water circulation processes, but they cannot ultimately achieve the effect of improving water quality in dead ends of water flow

[0004] At present, in order to solve this problem, mechanical water circulation and aeration equipment are usually installed in the "dead corner" of the water flow, but on the one hand, this method consumes a lot of energy, on the other hand, it can only temporarily improve the problem, and the solution effect is not good, so it is difficult to fully realize water circulation
