Problems solved by technology

[0002] With the development of industry, the situation of water pollution continues to deteriorate, and the shortage of water resources has seriously threatened people's lives. Microbiological treatment of sewage is now widely used in industrial sewage, domestic sewage and other fields as an effective method, and only microbial treatment of sewage is used. The method is very limited, the treatment capacity is small, and the effect is slow. There is an urgent need for a bacterial agent that can handle a large amount of sewage and quickly treat sewage, and comprehensively improve the sewage treatment capacity, so that the sewage can meet the basic discharge standards.

Abstract

The invention discloses a preparation method of microbial environment-friendly sewage treatment agent, comprising the following steps: activation of D61 cation exchange resin; activation of Pichia pastoris CGMCC 2.1801; activation of Bacillus megaterium CGMCC 1.223; activation of Pichia pastoris CGMCC 2.1801 and activated Bacillus megaterium CGMCC 1.223 were inoculated into the mixed strain medium for mixed culture to obtain a mixed bacterial solution; the mixed bacterial solution was mixed with activated D61 cation exchange resin, magnesium sulfate, activated carbon and plant ash to obtain a microbial environmental sewage treatment agent. Through repeated research and practice by the applicant, the present invention finds that the microbial environment-friendly sewage treatment agent of the present application can be directly used for sewage treatment, especially for the removal of nitrogen, phosphorus and potassium in industrial sewage, wherein the removal rate of nitrogen can reach about 96%, and the removal rate of phosphorus can reach about 96%. The removal rate can reach about 85%, and the removal rate of potassium can reach about 88%.
