[0002] With the gradual improvement of people's living standards, the sewage in life has gradually increased, so people have begun to pay attention to the treatment of sewage. A biofilm is a membranous substance composed of microorganisms, their surface secretions, and other impurities. The biofilm is used for sewage treatment mainly by using the microorganisms in the biofilm attached to the solid surface to metabolize and transform organic substances, ammonia nitrogen, phosphorus, etc. that can be utilized by organisms in the sewage, so as to achieve sewage purification. The biofilm method is a type of aerobic biological treatment technology for wastewater that is parallel to the activated sludge method. It is a fixed-film method and is the artificialization and intensification of the sewage soil self-purification process, mainly removing dissolved and colloidal organic pollutants in wastewater. The treatment technologies include biological filters (ordinary biological filters, high-load biological filters, tower biological filters), biological rotating disks, biological contact oxidation equipment, and biological fluidized beds, etc.
