Small-flow river water cleaning and pollution stopping system

Abstract

A small-flow river water cleaning and pollution stopping system comprises shore-based ecological beds, relaxation hydrophilic tribunes, ecological filtering beds and diversion rubber dams. The shore-based ecological beds are arranged on two shores of the river and in a slope structure, the shore-based ecological beds and water are separated through the relaxation hydrophilic tribunes, filtering layers are arranged on the side of the shore-based ecological beds, which are in contact with the relaxation hydrophilic tribunes, and a plurality of drainage openings are formed in the bottom of the relaxation hydrophilic tribunes. The ecological filtering beds are arranged in the water of the river and close to the sides of the shores, the middle of the two ecological filtering beds is a central region of the river, and the ecological filtering beds and the river central region are separated by permeable retaining walls and the diversion rubber dams on the permeable retaining walls. The ecological filtering beds are divided into upper and lower layers, filtering material layers are arranged on the lower layers, and soil layers are arranged on the upper layers. The ecological filtering beds are in rectangular or cambered structures and opened towards the river upstream direction to collect water from the upstream.

Description

technical field [0001] The invention relates to water environment treatment and river ecological restoration technology basins, in particular to a small-flow river water purification and pollution interception system. Background technique [0002] The flow of some rivers is small, or the water flow is small for a period of time with the change of seasons, while the rainwater runoff on both sides of the river, the receding of farmland and some other sewage discharges lead to the accumulation of pollutants in the river water environment, As a result, the pollution of rivers is increasing, the water environment is deteriorating, and the quality of human settlements is gradually declining. [0003] The existing methods of river governance mainly include physical methods, chemical methods and ecological restoration methods. Each method has advantages and strengths, but also has shortcomings and defects. [0004] With the increasing awareness of the ecological environment, river ...

AI Technical Summary

Problems solved by technology

[0007] The technical problem to be solved by the present invention is: in order to overcome and solve the problems of small flow river water purification and pollution interception treatment and the defects of the above invention, the present invention provides a small flow river water purification and pollution interception system with simple operation and less investment The project can not only purify the river water, maintain the green land, but also intercept and purify some pollution without affecting the normal flood discharge of the river, and at the same time achieve the harmony and unity of the river and the bank and beautify the environment
