At present, the urban pipe network has the conditions of rain and sewage converging and miscibility, so that a large amount of sewage is directly discharged into a river channel, and the phenomenon of poor water quality of river channel pollution is caused. The water quality of the water body drainage has the characteristics of large water quantity change, large pollutant concentration change and the like, and a plurality of ecological measures are aimed at drainage treatment at present, but the ideal effect is not achieved. The ecological floating island can be used for improving the water quality of the water body drainage, but has slower purification rate and general purification effect, and can only play an auxiliary role in drainage treatment. The membrane aeration biological membrane reactor (MABR membrane reactor) is a novel sewage treatment technology combining a gas separation membrane technology and a biological membrane method water treatment technology, and the working principle is that air enters the membrane wire through a pumping device and then penetrates through a membrane layer from the inside to be fused into a water body, and the MABR membrane reactor adopts a bubble-free aeration mode to supply oxygen, so that air bubbles cannot be generated to impact microorganisms attached to the membrane wire, and the growth of the microorganisms is facilitated. Due to the fact that the concentration of oxygen utilized by microorganisms on the surface of the membrane wires is different, an anaerobic layer, a facultative layer and an aerobic layer can appear, synchronous nitrification and denitrification of a water body are achieved, and the efficiency of pollutant removal is high.
