The water treated by the front-stage station is injected into the MBAR membrane reaction tank 10 through the water inlet 11, and the aerator 31 starts to work. The aeration is supplied to the bottom aeration plate 30 through the aeration pipe 32, and the MABR membrane reaction tank achieves the purpose of oxygenation. The mixed aqueous solution, under the action of the suction force of the bacterial clean water suction port 41, passes through the capillary pores of the MABR membrane group 20 and is pumped into the inner pores of the MABR membrane group, which greatly improves the solid-liquid separation efficiency.
