An Ecosystem for Reducing Pollutants from Stormwater Outlets Entering the Lake

Abstract

The invention discloses an ecological system for reducing pollutants in a lake's rainwater discharge outlet, which includes a lake discharge outlet, an inspection well is arranged at the lake outlet, a solid waste collection basket is arranged in the inspection well, and the lake outlet is peripherally arranged There is a biofilm treatment zone. The two ends of the biofilm treatment zone extend to the lakeshore on both sides of the lake outlet. The biofilm treatment zone includes floating beds connected in sequence. Wet plants are planted on the floating beds, and artificial aquatic plants are suspended on the floating beds. The floating bed is connected with the foundation pile of the floating bed through nylon ropes, aquatic plants are planted in the area surrounded by the biofilm treatment belt, and a fountain aerator is also arranged in the area surrounded by the biofilm treatment belt. The invention is easy to use, simple in construction technology, and has no civil engineering content. It has a wide range of applications and is easy to maintain. While reducing the pollution load, it has the effect of enriching the water surface landscape.

Description

technical field [0001] The invention mainly relates to the professional fields of environmental engineering and ecology, and in particular relates to an ecological system for reducing pollutants in lake rainwater discharge outlets. It is suitable for small and medium-sized lake water bodies with sewage outlets, and can reduce pollutants entering the lake while enriching the water surface landscape. Background technique [0002] Natural water bodies, especially small and medium-sized lakes in cities, have become a good place for people to get in touch with and get close to nature. These lakes often shoulder the functions of water bodies for people's leisure and entertainment. However, due to the development of cities, small and medium-sized lakes in cities often become places for sewage discharge. Sewage outlets and rainwater outlets carry various non-point source runoff pollutants directly into the lake, polluting the water quality, and further damaging the lake's ecosystem,...

AI Technical Summary

Problems solved by technology

[0003] The first essence of water pollution control and ecological restoration of small and medium-sized urban lakes is to control water first, and then to intercept pollution. However, some urban lakes are often located in the core areas of cities and towns. Extensive confluence outlets, coupled with well-developed surrounding businesses and dense residential buildings, make it relatively difficult to promote the work of sewage interception and management.
