The principle of integrated equipment for sewage treatment is based on the organic combination of the activated sludge microbial method and the biofilm biological method for biochemical treatment of sewage. In the treatment process, a large number of microorganisms grow on fixed and floating biological carriers to form a biofilm. As water and air impact and agitate the sewage, the bacteria and biofilm are renewed. During aeration, biological carriers are utilized to enhance the contact efficiency between microorganisms, pollutants in the sewage, and oxygen. The alternating effects of anaerobic, anoxic, and aerobic environments generated by the overall treatment equipment improve the purification capacity of different types of microbial communities for sewage, strengthening the removal of organic matter and the efficiency of nitrogen and phosphorus removal.

Scope of Application: Industrial and urban sewage treatment, among other fields.
