PU hydrolyzed bubble film for treating pollution on rivers and lakes

Abstract

The invention relates to a PU hydrolyzed bubble film for treating pollution on rivers and lakes, which is characterized in that: 14 to 18 weight percent of indigenous flora promotion preparation, 10 to 14 weight percent of aquatic creature promotion preparation, 1.5 to 2.5 weight percent of natto plant polysaccharide kinase and 67 to 73 weight percent of hydrolyzed PU material are mixed and stirred uniformly, and then subjected to foam forming in a mold so as to produce the PU hydrolyzed bubble film. The PU hydrolyzed bubble film is planted in the rivers and lakes so as to hydrolyze and slowly release basic nutrient sources of biological diversity of the rivers and lakes, reduce rainwater consumption in flood season or solar evaporation consumption in dry season through non-disposable release, provide microelement organic nutrient sources for ecological microorganisms continuously, stabilize the basic life of living beings and strengthen breeding, make full use of metabolic activity of the microorganisms, degrade organic pollutants in the water, reduce the total quantity of pollutants of the rivers and lakes, keep the ecological balance of the biological diversity of the rivers and lakes, and ensure treating effect and stability.

Description

【Technical field】 [0001] This field belongs to the field of environmental protection, and specifically relates to a PU hydrolysis foam film used for treating river and lake pollution. 【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 drainage, storage, and pollution in the past have generally suffered from black and smelly phenomena. [0003] The root causes of the black and smelly rivers and lakes are as follows: 1. Rain and sewage diversion: Although a centralized domestic sewage pipe network is built in densely populated areas to intercept sewage and sewage to the sewage treatment plant, the sewage from the laundry of the migrants in the rented houses is discharged from the balcony. The sewage interception function is inc...

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
