Problems solved by technology

[0005] At present, the methods for ecological restoration of eutrophic waters in China mostly use submerged vegetation restoration or only filter-feeding fish to control algae to purify water quality, and usually in small-scale (such as less than 100 mu) closed water bodies, or in It can artificially control the water level, artificially control the water flow and other water areas for ecological water treatment, but for larger-scale water bodies, it is difficult to achieve ideal results with this single method

Abstract

The invention relates to a compound microorganism bacterium agent which consists of Rhodopseudomonas palustris bacteria liquid, Alcaligenes faecalis bacteria liquid, Acinetobacter calcoaceticus bacteria liquid and bacillus megatherium bacteria liquid according to a volume ratio of 1:(2-3):4:2, wherein the amount of viable organisms in the four kinds of bacteria liquid is 2*10<8>cfu / ml. The invention also provides application of the compound bacterium agent in eutrophic water body treatment. The water body is subjected to pollution treatment through the four composite microbes, so that polluted substances in the water body are decomposed and metabolized, pollutants in the water body are degraded by stimulating growth of indigenous microorganisms in the environment, the index of each pollutant in the treated water body is obviously reduced, the dirt removal effect is good, and the removal rate is high.

Description

technical field [0001] The invention belongs to the field of biological technology, and in particular relates to a microbial composite bacterial agent and its application in the treatment of eutrophic water bodies. Background technique [0002] In recent years, the phenomenon of water pollution and eutrophication has been very serious. From a national perspective, among the 27 key lakes and reservoirs monitored, 20 lakes and reservoirs have water quality of IV-bad V, as high as 74%. Among them, the water quality of the "three lakes" (Taihu Lake, Chaohu Lake, and Dianchi Lake) is inferior to Class V, and the main pollution indicators are total nitrogen, total phosphorus, chemical oxygen demand, and chlorophyll a. Especially in May 2007, the Taihu Lake cyanobacteria bloom event directly affected the drinking water safety of Wuxi residents. The improvement of the environmental quality of surface waters is facing unprecedented challenges. [0003] In recent years, with the dev...
