River and lake ecological restoration system

Abstract

The invention provides a river and lake ecological restoration system and relates to the technical field of river and lake water purification. The river and lake ecological restoration system providedby the invention comprises an upstream ecological purification floating island, a mid-stream aerated and medicated fountain, a downstream ecological purification floating island and an ecological pollution isolation fence, wherein the upstream ecological purification floating island is arranged on the upstream of a river or a lake, for the treatment of upstream river and lake water; the mid-stream aerated and medicated fountain is arranged on the bank of the river or the lake, for aeration and medication into mid-stream river and lake water; the downstream ecological purification floating island is arranged on the downstream of the river or the lake, for the treatment of downstream river and lake water; the ecological pollution isolation fence is arranged at a tributary entrance or a pollution discharging opening of the river or the lake for the interception of foreign pollutants. The river and lake ecological restoration system provided by the invention can more comprehensively treatthe upstream, the mid-stream and the downstream of the river or the lake and can simultaneously intercept the foreign pollutants to realize the systematic management of the river or the lake, therebybeing suitable for the large-area river or lake.

Description

technical field [0001] The invention relates to the technical field of river and lake water purification, in particular to an ecological restoration system for rivers and lakes. Background technique [0002] With the development of social production and the continuous improvement of people's living standards, people's pollution of rivers and lakes is becoming more and more serious. The pollution of rivers and lakes has become a problem that is increasingly concerned. Residential garbage, domestic wastewater, agricultural and animal husbandry waste, etc. are directly discharged into river lakes, causing a sharp increase in aerobic organic pollutants and nitrogen and phosphorus nutrient content in river lakes, resulting in eutrophication of water bodies, stench and blackness. [0003] The application range of traditional ecological restoration technology is narrow, the restoration method is relatively simple, and the restoration area is only a small part of the water area, rat...
