Slow-release microorganism microbial inoculum for government of black and odorous water body and preparation method of slow-release microorganism microbial inoculum

Abstract

The invention discloses a slow-release microorganism microbial inoculum for government of a black and odorous water body and a preparation method of the slow-release microorganism microbial inoculum.The slow-release microorganism microbial inoculum comprises the preparation raw materials of microorganism microbial liquid, an adsorption agent, an activator and an entrapping carrier. The slow-release microorganism microbial inoculum has various microorganism kinds, and is high in microorganism loading quantity, coexistent and alternative in microorganisms, long-acting in stability, shock-resistant, free from secondary risks, high in removal efficiency of pollutants and the like. When being applied to the black and odorous and eutrophic water bodies, the slow-release microorganism microbialinoculum can rapidly adapt to environment, the activator can promote quick propagation of the microorganisms, pollutants in the water bodies can be effectively removed, COD, NH3-N, TP and total nitrogen in the water bodies are effectively reduced, odor taste of the water body is eliminated step by step, and the transparency of the water bodies is improved.

Description

technical field [0001] The invention relates to a slow-release microbial bacterial agent for treating black and odorous water bodies and a preparation method thereof. Background technique [0002] Black and odorous urban rivers are one of the most prominent environmental problems in China today. Since the reform and opening up, my country's economy has developed rapidly and the urban population has increased rapidly. Most of the industrial wastewater and domestic sewage are directly discharged into rivers or lakes without effective treatment. With the continuous increase of organic pollutants flowing into rivers and lakes, the self-purification capacity of rivers and lakes has been exceeded, resulting in changes in water ecology, and finally resulting in seasonal or year-round black and odorous phenomena in water bodies. Since the release of the "Water Ten Measures" in 2015, the management of urban black and odorous rivers has always attracted attention. The Water Ten Arti...

AI Technical Summary

Problems solved by technology

The main treatment methods are: artificial aeration, sediment dredging, water diversion, coagulation and sedimentation, magnetic separation, ecological floating bed, artificial wetland, biological growth promotion, etc., but these methods have a long purification cycle and poor treatment effect, basically treating the symptoms Does not cure the root cause, the treatment cost is relatively high, and it is difficult to apply continuously for a long time

[0005] The microbial agents on the market today generally have problems such as single strains, competition among strains, poor adaptability, inability to fix and attach to the river bed, one-time action, high price, and unsatisfactory treatment effects for black and odorous water bodies.
