River flowing muddy water mud and sand holding and filtering treatment station

Abstract

The invention discloses a river flowing muddy water mud and sand holding and filtering treatment station which belongs to the technical field of the water conservancy project. The river flowing muddywater mud and sand holding and filtering treatment station comprises a mud and sand holding device, a filtering device and a membrane bag back-washing device. According to the river flowing muddy water mud and sand holding and filtering treatment station disclosed by the invention, the mud and sand holding device and the filtering device are arranged, the mud and sand holding device holds mud andsand in a muddy water body of a river, so that preliminary filtration of the muddy water body is realized; further filtration is realized through the filtering device, so that a water body which flowsinto the river is a transparent water body, and therefore, the muddy problem of the river water body is solved; and the back-washing device is arranged to realize automatic back-washing on a filtering membrane bag, so that the filtration effect of the filtering device is guaranteed, and therefore, the treatment station realizes long-term and effective mud and sand holding and filtering of river flowing muddy water.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a treatment station for intercepting and filtering river flowing muddy cement sand. Background technique [0002] As we all know, the turbidity of existing flowing rivers has increasingly become one of the problems that human beings need to solve, especially the artificial lakes in cities. Due to the turbidity of the water, the aesthetic effect and drinking needs of the city are affected. [0003] Taking Slender West Lake in Yangzhou as an example, the lake (river) water in the scenic spot has high turbidity. Because the upstream water source passes through the clay and sub-clay channels, the incoming water continuously brings in mud and sand, which increases the sediment at the bottom of the lake, making the water in the scenic spot turbid; There are no sand-cutting and mud-cutting measures that can accurately and symptomatically solve the turbidity of flow...

AI Technical Summary

Problems solved by technology

Dredging only treats the surface, but fails to solve the key problem of the continuous flow of mud and sand from the upstream water. However, the daily flow of Slender West Lake is as high as 720,000 cubic meters, and the sediment content of the water body is estimated to be 3 / 10,000, which is about 200 cubic meters per day. Flowing mud and sand enter, and since the bottom of the Slender West Lake Scenic Area is greater than the depth of the downstream river, most of the flowing mud will naturally be retained, and a small part of the flowing mud will flow down the river. Overall, it still makes it difficult to reduce the turbidity of the overall water body ;even with brutal dredging at the cost of destroying the ecosystem of native plant roots, the turbidity is still high
