[0002] In recent years, with the rapid development of city, the river eutrophication, nitrogen and phosphorus over standard and other problems caused by human activities and life pollution into river are increasingly intensified. At present, there is still a big gap in the collection and treatment capacity of urban domestic sewage, and the separation of rainwater and sewage is not in place. Black and odorous water bodies, heavily polluted river scattered sewage discharge, rainwater and sewage mixing, sewage overflow and other situations occur frequently, and sewage treatment and purification work needs to be carried out urgently.

[0003] MBBR technology, as one of the important means to treat domestic sewage, mainly uses the biological membrane formed by the adhesion of suspended carrier filler to treat pollutants in raw water through the assimilation and dissimilation of microbial membrane microorganisms. Different microorganisms can grow and metabolize using organic matter or inorganic matter in different environments such as anaerobic, anoxic and aerobic. Through the adsorption, degradation and transformation of bacterial microorganisms, protozoa and metazoan, the removal of pollutants in water body is realized, and the preparation of microbial inoculant used has important practical value.
