An ecological water purifying agent used for urban river course purification

Abstract

An ecological water purifying agent used for urban river course purification is disclosed. The water purifying agent is obtained by mixing complex microorganisms, bio-enzymes, a curing agent and plantextract products. The complex microorganisms include bacillus coagulans, nitrifying bacteria, denitrifying bacteria, rhodopseudomonas palustris, photobacteria and yeast. The bio-enzymes include lipase, amylase, laccase and cellulase. The curing agent includes zeolite powder, attapulgite clay and montmorillonite. The plant extract products include bamboo juice and a moringa oleifera extract product. A preparing method of the ecological water purifying agent used for urban river course purification is also disclosed. The water purifying agent has advantages of significant water purification effects through combined functions of the bio-enzymes, the curing agent and the plant extract products, and great practical significance for urban river course purification.

Description

technical field [0001] The invention relates to the field of water body purification, in particular to an ecological water purifier for urban river purification and a preparation method thereof. Background technique [0002] According to a survey of water eutrophication by the United Nations Environment Program (UNEP), 30%-40% of lakes and reservoirs worldwide are being affected to varying degrees. In the past 20 years, the eutrophication of my country's water bodies has developed rapidly. At present, 77% of lakes and 35.8% of reservoirs are in a state of eutrophication. Although the degree of eutrophication of rivers is generally not as serious as that of still water bodies such as lakes and reservoirs, reports on eutrophication of rivers have increased day by day in recent decades. It can be seen that eutrophication has become the most important environmental problem in my country's water environment protection. [0003] At present, the main methods used for the treatment...

Problems solved by technology

[0005] Most of the existing microbial preparations are microbial composite preparations mixed with microorganisms and biological enzymes, which simultaneously degrade various pollutant indicators (COD, ammonia nitrogen, TP, etc.). There are often many restrictions: (1) during storage and transportation, due to the existence of biological enzymes, its storage conditions will be more stringent, and improper storage and transportation conditions will inevitably seriously affect the working efficiency of the preparation after it is put into actual use; ( 2) When microbial composite preparations are put into water bodies, most microbial preparations are prone to poor impact resistance or other practical application conditions, resulting in unsatisfactory treatment effects
