Abstract

The invention relates to a composite microbial preparation for treating a black and odorous river and a preparation method thereof. The composite microbial preparation is made from: Thiobacillus denitrificans powder 40-60 parts, composite Bacillus powder 10-40 parts and composite Saccharomyces cerevisiae powder 10-40 parts. Strains for degrading sulfides and organics in black and odorous sediment and suitable for growing in the black and odorous sediment are specifically screened, the combination of Thiobacillus denitrificans efficient in degrading hydrogen sulfide and removing nitrogen, Bacillus amyloliquefaciens capable of generating rich enzymes such as protease, amylase and cellulase, Saccharomyces cerevisiae, Candida utilis and facultative anaerobic Bacillus licheniformis enables the preparation to quickly improve the water quality of the black and odorous river and remove sediment blackness and odor.

Description

technical field

[0001] The invention relates to the technical field of treatment of black and odorous rivers, in particular to a composite microbial bacterial agent for rapidly controlling black and odorous rivers and reducing sediment and a preparation method thereof. Background technique

[0002] With the development of my country's economy and the increase of population, the water consumption is constantly increasing, and a large amount of farmland runoff without effective treatment, industrial wastewater and domestic sewage are discharged into rivers, and some rivers are almost reduced to pollution-inducing rivers. The pollution concentration has far exceeded the self-purification capacity of the river, and most of the river has been in a state of black and odor for a long time, seriously affecting the life of residents along the river and the image of the city. A large number of water pollutants are silted up, the thickness of the sediment is increasing, and the cross s...
