Comprehensive treatment method for repairing in-situ biological diversity in rivers and lakes

Abstract

The invention relates to a comprehensive treatment method for repairing the in-situ biological diversity in rivers and lakes, which is characterized in that the bottom sediments in water areas are quickly purified by taking indigenous bacteria from the rives and the lakes and regulating the pH value; the colonization of the original zoological biological diversity is strengthened by utilizing the nutrition preparation of a PU (Polyurethane) hydrolysis bubble film to degrade organic pollutants. The invention has the advantages that foreign ecological strains are not introduced, thus no variety appears, no secondary or micro-pollution nuisance appears; an automatic aerator is not arranged and sludge is not cleaned, thus the operation and maintenance cost and the investment of equipment are greatly reduced, the effect is obvious and good; and the cannel drainage function and the natural purification function are not influenced in the course of treatment and after the treatment.

Description

【Technical field】 [0001] This field belongs to the field of environmental protection, and specifically relates to a comprehensive treatment method for in-situ biodiversity restoration of rivers and lakes led by the technology of purifying and rejuvenating native bacteria, multiplication and cultivation. It is widely used in closed and semi-enclosed eutrophic water bodies such as rivers, lakes, reservoirs, aquaculture ponds, etc., where sewage is not completely intercepted, cannot be intercepted into the pipe network, and cannot be dredged for a while, and rivers and lakes that are affected by tides and change for original ecological biological Restoration of diversity. 【Background technique】 [0002] Due to the rapid increase of the population in the convenient urban area of ​​the economic development, the improvement of people's living standards, and the expansion of the urban and rural areas, the rivers and lakes that used to be used as landscapes, irrigation, flood draina...

AI Technical Summary

Problems solved by technology

However, it is unreasonable to take engineering measures for river regulation at present. The water source of rivers and lakes must rely on the flood season to intercept sewage, that is, to cut off the flow. During the dry season, most of the biodiversity is lost; sludge cleaning, water replenishment, and water diversion are only to transfer sludge pollution and pollution. The diluted water body is transferred to the downstream, causing the water quality of the water area to deteriorate; sometimes hardware facilities are built or aerators are installed in rivers and lakes
