Integrated process and equipment for eutrophic water body control

Abstract

The invention discloses an integrated process and equipment for eutrophic water body control. The process comprises multiple stages of fast filtering work procedures, a strong oxidation work procedure and a deep adsorption work procedure, wherein the multiple stages of fast filtering work procedures operate in a serial connection way. Suspended substances and algae cells in the water body can be fast filtered; phycotoxin, nitrogen and phosphorus nutrients and organic contaminants can be effectively removed; meanwhile, the effect of improving the water body dissolved oxygen can be achieved, so that the control effect of resolving the current problems and eliminating the root causes is achieved. In addition, through technology integration, the developed equipment is portable and intensive; the moving and the transportation are convenient; the process and the equipment are particularly applicable to the prevention and the emergency treatment of slight eutrophic water body algae bloom in urban view and scape lakes, medium-and-small-sized reservoirs and semi-sealed gulfs.

Description

Technical field [0001] The invention belongs to the field of water environment treatment, and specifically relates to an integrated process and equipment for treatment of eutrophic water bodies. Background technique [0002] The rapid development of social economy has led to an intensified process of eutrophication in lakes and reservoirs. The main manifestations are the decrease of dissolved oxygen, the increase of nutrient content, the deterioration of water quality, and the increase of planktonic algae content. The extreme manifestation is the outbreak of water blooms. It will not only cause serious harm to the water environment, destroy the ecological balance, and even cause the water area to lose its use function, causing major losses in water resources and regional economy. Therefore, the control of natural water body eutrophication risks and the rapid and effective emergency treatment of sudden water quality incidents, effectively reducing the input of nutrients and pollu...

AI Technical Summary

Problems solved by technology

Its disadvantages are: phosphorus treatment efficiency is low, and it occupies a large area

Its disadvantages are: the addition of chemical agents increases the solid content in the water body, which is likely to cause secondary pollution of the water quality, and the treatment cost is relatively high

Its defect is that it destroys the algae cell body, causes the release of algae toxin, easily produces secondary pollution, and has an impact on water safety
