The biological water purification process has attracted much attention, and the pollutants in the sewage are extremely complex. The main components of general domestic sewage are metabolic wastes and food residues. Industrial wastewater may contain more metals, phenols, formaldehyde and other chemicals. In addition, sewage also contains a large number of non-pathogenic microorganisms and a small amount of pathogenic bacteria and viruses. Biological treatment of sewage is to take the mixed microbial community in sewage as the main body of work to absorb and transform various organic pollutants in sewage, and at the same time, through diffusion, adsorption, coagulation, oxidative decomposition, precipitation and other functions to remove pollution in water thing.

The most common sewage treatment methods are mainly aerobic biological treatment or anaerobic biological treatment according to different types of sewage treatment. The above two methods mainly use the aerobic microbial community and anaerobic biological community to eliminate or degrade. The sewage is dirty.
