The aeration in the aeration tank and the lifting action of water flow enable the carrier to be in a fluidized state, and further form suspended growth activated sludge and attached growth biomembranes, so that the moving bed biomembranes use the whole reactor space, the superiority of attached phase and suspended phase organisms is fully exerted, and the advantages are exploited, the disadvantages are avoided, and the advantages are mutually supplemented. Unlike previous packings, suspended packings are called "mobile biofilms" because they are able to come into contact with the sewage many times. The suspended carriers of a certain amount improve the biomass and the biological species in the reactor, thereby improving the treatment efficiency of the reactor, and because the density of the filler is close to that of water, the filler is completely mixed with the water during aeration, and the environment for the growth of microorganisms is three phases of gas, liquid and solid. The collision and shearing action of the carrier in water makes air bubbles finer, and the utilization rate of oxygen is increased. In addition, each carrier has different biological species inside and outside, anaerobic bacteria or facultative bacteria grow inside, and aerobic bacteria grow outside, so that each carrier is a micro-reactor, nitrification reaction and denitrification reaction exist simultaneously, and the treatment effect is improved. The membrane component replaces a secondary sedimentation tank at the tail end of the traditional biological treatment technology, the concentration of the high-activity sludge is kept in a bioreactor, the organic load of biological treatment is improved, the occupied area of a sewage treatment facility is reduced, and the excess sludge amount is reduced by keeping low sludge load. Mainly utilizes the membrane separation equipment immersed in the aerobic biological tank to trap the activated sludge and macromolecular organic matters in the tank. The concentration of activated sludge (MLSS) in the membrane bioreactor system can be increased to 8000-10,000 mg/L or even higher; the sludge age (SRT) can be prolonged to more than 30 days. The membrane bioreactor can retain microorganisms with longer generation period due to effective interception, can realize deep purification of sewage, simultaneously nitrifying bacteria can be fully propagated in the system, has obvious nitrification effect, and provides possibility for deep phosphorus and nitrogen removal. Simple operation, strong controllability, thorough sewage and wastewater treatment, and investment and floor area saving.
