Method for restoring existing lake water ecosystem

Abstract

The invention discloses a method for restoring an existing lake water ecosystem. According to the method, basic condition improvement (water level maintenance, water quality improvement and bottom mud improvement), a filamentous alga (spirogyra) preventing technology, a transitional zone flushing preventing technology system, a water inlet front reservoir treatment system, shallow water zone sinking and floating leaf vegetation planting, deep water zone sinking vegetation planting, food net chain rebuilding, a sediment-water interface biological system, a microbial film reinforcing system, a species diversity habitat system and an ecological water purification system long-acting management are included. Through the method, water pollution loads are effectively lowered, the water self-purification capacity is improved, water is clear and free of heterochrome and peculiar smells, and therefore the water is suitable for being touched by people.

Description

technical field [0001] The invention belongs to the technical field of water environment pollution control, and in particular relates to the restoration of an existing lake water ecosystem. Background technique [0002] With the development of industry, the continuous improvement of people's living standards, and the continuous deterioration of the global environment, the control of water pollution and the improvement of the ecological environment have entered a relative bottleneck period; the water cycle system is fragile, the quality of the water environment is declining, and the water function is degraded. Research on urban sewage collection and treatment, surface runoff pollution control, urban water function restoration, and water body ecological landscape construction. A series of advanced water pollution control, ecosystem construction and restoration, and waterscape optimization technologies have been developed for urban rivers, water supply reservoirs, natural lakes...

AI Technical Summary

Problems solved by technology

[0004] At present, in the treatment technologies of existing lakes with deteriorating water quality, power water exchange, mechanical filtration, chemical disinfection, and microbial strain stocking technologies are mostly used. The above technologies can make the water quality of the lake clear, but they all have high costs and short effect periods. , high maintenance costs, secondary pollution and no fundamental solution to the problem, can not completely solve the development of water eutrophication

In addition, these technologies are single technologies, and the degree of technology integration is not high, which limits the application of technology
