Historic village pollution interception and water body purification system

Abstract

The invention relates to a historic village pollution interception and water body purification system, which comprises an ecological embankment, a sidewalk, filtering islands and a water separation dam, wherein the ecological embankment is positioned on the shore of a water body and is of a slope type structure; the ecological embankment and the water body are separated by the sidewalk; a filtering wall is arranged at one side, in contact with the sidewalk, of the ecological embankment; a plurality of water discharging openings are formed in the bottom of the sidewalk; the filtering islands are positioned at one side, near the shore, in the water body; a water flow region is formed between the two filtering islands; the filtering islands and the water flow region are separated by a water permeable baffle wall and a water separation dam arranged on the water permeable baffle wall; the filtering islands are divided into an upper layer and a lower layer; the lower layer is a filtering material layer; the upper layer is a soil layer; the filtering islands are of rectangular or arc-shaped structures, and are provided with openings in a direction towards the upper stream of the water body so as to accommodate the flowing water from the upper stream.

Description

technical field [0001] The invention relates to water environment treatment and water body ecological restoration technology basin, in particular to an ancient village pollution interception and water body purification system. Background technique [0002] The water bodies in many ancient villages are neglected. In addition, the rainwater runoff on the shore, farmland receding water and other sewage discharges lead to the accumulation of pollutants in the water environment. The quality has also gradually declined. [0003] The existing water treatment methods mainly include physical methods, chemical methods and ecological restoration methods, each of which has advantages and strengths, but also has shortcomings and defects. [0004] With the increasing awareness of the ecological environment, water body improvement projects have attracted more and more attention. People began to respect and protect the natural features and ecological functions of rivers and other water bod...

AI Technical Summary

Problems solved by technology

The purification effect of the invention patent is obvious, but the patent has the following defects: ①The environmental changes and disturbances of the original river are relatively large, destroying the original ecological environment; ②The engineering volume is large; ③The ecological system is monotonous; Poor degree

The invention patent is easy to operate and has remarkable effects, but the patent has the following defects: ① completely changes the flow rate and flow of the river, and destroys the original living environment of organisms; ② causes the downstream of the rubber dam to lack water, or even dry up; ③ the rubber dam The downstream ecological environment will further deteriorate
