Abstract

The invention discloses a black and odorous water body treatment microbial inoculum and a preparation method thereof. The treatment microbial inoculum comprises polyacrylamide, persulfate, ferrate, polyaluminum chloride, zeolite and compound microorganisms. The compound microorganisms comprise sulfur bacteria, nitrifying bacteria, Pseudomonas aeruginosa, Bacillus subtilis, Candida tropicalis and actinomycetes. The preparation method comprises the following steps: co-culturing strains in the compound microorganisms to obtain a compound bacteria solution, and then performing centrifugal drying to obtain compound microorganisms; processing sulfate and the ferrate into a solution A, processing the polyacrylamide, the polyaluminum chloride and the compound microorganisms into a solution B, adding the solution A into the solution B mixed with the zeolite in batches, performing stirring for a period of time, and performing vacuum low-temperature drying to obtain the target microbial inoculum.The microbial inoculum prepared by the method provided by the invention can improve the BOD removal rate and COD removal rate of sewage to 99% or above, and can effectively solve the problems of lowblack and odorous water body treatment efficiency and easy secondary pollution.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a black and odorous water treatment bacterial agent and a preparation method thereof. Background technique [0002] In the process of urbanization, due to the impact of human activities, a large amount of pollutants enter the water body through atmospheric deposition, wastewater discharge, rainwater erosion, etc., and finally deposit in the bottom mud and gradually enrich. The bottom mud of eutrophic rivers is generally seriously polluted , The pollutants in the sediment are repeatedly mixed with the water body, making it difficult for the water quality to meet the standard. The aggravation of sediment pollution is mainly caused by human factors. In the process of rapid economic development, a large amount of organic pollutants enter the river, and organic pollutants accumulate in the river sediment, which will cause the water body to stink and black, while T...
