Construction method of bow-shaped ecological corridor for purifying low-pollution water entering the river

Abstract

The invention provides a construction method for a bow-shaped ecological corridor for purifying low-pollution water flowing into a river, and belongs to the technical field of resource and environmental protection. The construction method of the bow-shaped ecological corridor used to purify the low-pollution water entering the river includes the construction of the water diversion system into the river and the construction of the water-passing corridor. The construction of the water-passing corridor adopts the following methods: a. Set up a U-shaped water barrier in the channel, and the water barrier will enclose the low-pollution water flowing into the river and flow in a U shape; b. Set up several water barriers composed of water barriers and grilles in the water corridor ; c, laying geomembrane at the bottom of the water corridor; d, laying zeolite above the geomembrane; e, setting multiple cleaning pipes between two adjacent water barriers; Laying fishing nets on the water surface; g, laying floating plants on the fishing nets of the water corridor. The invention can realize the acceleration and purification of the rainfall runoff of pipe row or ditch row of various rivers and agricultural production drainage pollutants.

Description

technical field [0001] The invention belongs to the technical field of resources and environment protection, and relates to a bow-shaped ecological corridor, in particular to a construction method of a bow-shaped ecological corridor for purifying low-pollution water entering a river. Background technique [0002] With the effective control of point source pollution such as industrial wastewater and urban domestic sewage in our country, non-point source pollution mainly caused by rainfall runoff and agricultural production drainage have replaced point sources as the most important source of water environmental pollution. [0003] At present, through the construction of sponge cities in China, good results have been achieved in reducing the stock of rainfall runoff and reducing the pollution load in drainage; at the same time, many effective methods have been developed in terms of rural non-point source pollution control, especially In terms of farmland non-point source pollut...

Problems solved by technology

[0004] Due to the small per capita arable land area in my country, it is impossible to build water corridors that can meet their needs, and the treatment technology of riverside and pond systems is at the expense of production such as water aquaculture, and due to the layout of riversides and ponds, it is also Limits the practical application of the technology
