Analysis of the diversity of microbial communities in typical domestic sewage

This review paper mainly introduces the relationship between domestic sewage treatment and microbial communities. First, the paper provides an overview of the source and composition of domestic sewage and the importance of microbial diversity in domestic sewage treatment. Then, the paper summarizes the current research status of microbial communities in typical domestic sewage. In the second part, the paper explores the factors affecting the microbial diversity in domestic sewage[i]. Then, in the third part, the paper describes the diversity of microbial communities in typical domestic sewage, respectively from the biological classification community composition and functional classification community composition. In the fourth part, the paper explores the ecological functions of microbial communities in domestic sewage. Finally, in the fifth part, the paper analyzes the influence of the traditional sewage treatment process and the new sewage treatment technology on the microbial community, and introduces the indicator role and assessment method of the microbial community. It provides an important reference for further research and optimization of domestic sewage treatment.
