The sewage enters the filler part of the anaerobic filtration treatment tank 11 through the sewage inlet diversion trench 110, and a large amount of microorganisms can be attached to the polyurethane filler to form an anaerobic biofilm. Under anaerobic condition, the anaerobic microorganisms on the surface of the filler can preliminarily remove organic pollutants in the sewage, hydrolyze the macromolecular pollutants which are difficult to degrade in the sewage into micromolecular pollutants which are easy to degrade, convert organic nitrogen into soluble inorganic nitrogen, improve the biodegradability of the sewage, and lay a good foundation for the biological treatment of the next stage.

The denitrifying bacteria in the facultative biomembrane reduce the nitrate in the sewage into molecular nitrogen (N) under the anoxic condition₂) And carrying out denitrification reaction. The aeration air source fan 20 intermittently aerates the anoxic biochemical treatment tank 12 through a first aeration pipe 123 arranged at the bottom of the anoxic biochemical treatment tank 12.

The sewage treated by the anoxic biochemical treatment tank 12 enters the aerobic aeration treatment tank 13 through the connecting pipe 15. The second aeration pipe 133 aerates the aerobic aeration treatment tank 13 through the aeration air source fan 20 to ensure that the dissolved oxygen in the aerobic aeration treatment tank is 2-4 mg/L. The combined filler has good microbial adhesion and high biofilm activity, and the filler has the function of cutting bubbles, so that the aeration effect can be further improved. Aerobic microorganisms in the biomembrane further remove organic pollutants in the sewage, nitrifying bacteria carry out nitration reaction under aerobic conditions to oxidize ammonia nitrogen in the sewage into nitrate nitrogen, phosphorus accumulating bacteria in the sewage carry out phosphorus release reaction in an anaerobic zone, and can excessively absorb phosphorus under aerobic conditions and remove the phosphorus in a residual sludge form, so that the phosphorus is removed.

The sewage treated by the aerobic aeration treatment tank 13 enters the tail end sedimentation treatment tank 14 through the overflow treatment tank 141. Wherein, a part of the sewage flows back to the anaerobic filtration treatment tank 11 through the reflux water pipe 143 in a way of air stripping reflux, and the other part of the sewage enters the disinfection treatment tank 142 and is discharged into the local storage water body after being disinfected by the immersed ultraviolet disinfection lamp tube 146.
