With the implementation of the national rural revitalization strategy, higher requirements have been put forward for the governance of rural water environment. Efficient microbial technology utilizes the characteristics of easy reproduction and strong degradation of microorganisms to isolate, domesticate, purify, and expand cultivation of microbial colonies. On this basis, Chemical oxygen demand (COD), P, N, etc. in the water are used as nutrients, and suitable colonies are selected to breed rapidly in poor water environment, so as to rapidly degrade organic pollutants in the water and improve the quality of the water environment. By screening native microorganisms in water and selecting microbial strains from the dominant colonies as microbial colonies, carrier matrices are used for microbial degradation through live water circulation and adsorption immobilization processes. Compared with the separate addition of solidified carrier matrix group and the addition of free microbial group, the degradation rate of various pollutants has been greatly improved, which can be better applied to rural black and smelly Water purification purification projects.
