[0002] Biofilm filtration is a technology that uses biofilms for filtration and treatment. During the biofilm filtration process, microorganisms will attach to the surface of the filter medium to form a layer of biofilm. This biofilm can effectively capture, degrade and transform pollutants in the water, such as organic matter, nitrogen, phosphorus, etc. The biofilm has a large specific surface area and a rich microbial community, and can purify sewage or other liquids through the metabolic activities of microorganisms.

[0003] During the biofilm filtration process, microorganisms will attach to the surface of the biological filler to form a biofilm, which can effectively capture, degrade and transform pollutants in the water. The biofiller will now be used to purify the water quality in the freshwater plant.
