Technical Field

[0001] The utility model relates to the technical field of biological filter tanks, and more specifically, to a structure of a stainless steel biological filter tank. Background Art

[0002] As a common sewage treatment process, biological filter tanks can effectively remove suspended solids, ammonia nitrogen, organic matter and other impurities in sewage. In biological filters, granular fillers with high specific surface area are generally loaded, which can filter and intercept suspended solids while serving as a carrier for the growth of microbial films, so that organic matter, ammonia nitrogen and other impurities in sewage can be degraded by biochemical reactions with the biofilm on the surface of the filler.

[0003] Microorganisms reacting with sewage will also produce sludge, which stays between the microbial fillers, reducing the biological filter's ability to treat sewage. Currently, the biological fillers are generally backwashed by pumping water from the outlet side into the microbial fillers, but the sludge is located between the fillers, the flushing efficiency is low, and the flushing effect is not ideal.
