Black and odorous river branch repairing system and application thereof

Abstract

The invention provides a black and odorous river branch repairing system and application thereof, and relates to the technical field of black and odorous water body treatment. The black and odorous river restoration system comprises an ecological floating island and an electrode electrolysis device arranged in sludge at the bottom of the black and odorous river, wherein the ecological floating island treats pollutants in a water body of the black and odorous river through a floating island platform. The electrode electrolysis device is used for electrolyzing and removing bottom mud pollutants in the black and odorous river. Meanwhile, the ecological floating island further comprises an electric energy control system arranged on the water surface, and the electric energy control system can provide energy for the black and odorous river branch repairing system. According to the black and odorous river repairing system, through mutual cooperation of all the units, various pollutants in bottom mud can be degraded through an electrolytic method while the black and odorous river water body is treated, then the water body treatment process and the bottom mud electrolysis process are combined, and the technical effect of synchronously treating the overlying water body and the bottom mud of the black and odorous river is achieved.

Description

technical field [0001] The invention relates to the technical field of black and odorous water treatment, in particular to a black and odorous river surge restoration system and its application. Background technique [0002] At present, the treatment technology of black and odorous water mainly adopts the combination of physical technology, biological and ecological treatment technology, of which physical technology mainly controls source pollution, sediment dredging and restoration, enhanced aeration and living water circulation technology, etc. Biological and ecological treatment technologies mainly include constructed wetlands, ecological floating islands, microbial agent technology, etc. Among them, ecological floating islands are widely used in the treatment of black and odorous water bodies. Traditional ecological floating islands have the problems of low pollutant removal rate and unstable treatment effects easily affected by the environment. By adding physical and ch...

AI Technical Summary

Problems solved by technology

However, the above-mentioned black and odorous water treatment technology mainly has the following disadvantages: First, in the existing technical scheme, iron carbon and microbial agent are mixed in the geotextile bag, and after a period of reaction, the flocs such as iron sludge will affect The permeability of geotextile bags is not conducive to the contact between bacterial agents and pollutants, resulting in weak stability of black and odorous water bodies. The second point is that it is necessary to arrange multiple geotextile bags and erect aeration pipes, which requires a large amount of work. At the same time, it is necessary to maintain the pipeline and replace the bag regularly. Since the pipeline is arranged near the bottom mud, the maintenance cost is relatively high

Third, the microbial agent is expensive and is a consumable material, which makes the overall treatment cost of the river relatively high
