High-viscosity wastewater MBR membrane frame Technical Field The utility model relates to the technical field of sewage treatment, in particular to a high-viscosity wastewater MBR membrane frame. Background MBR technology combines biological treatment and membrane filtration, and is widely applied in the field of sewage treatment. In the prior art, MBR membrane frames are typically composed of a membrane module, an aeration system and a support structure. The membrane component is used for intercepting microorganisms and pollutants in water to realize purification of water quality, and the aeration system is used for generating water flow by introducing air into the membrane pool so as to prevent sludge from depositing on the surface of the membrane and simultaneously provide oxygen required by the microorganisms. The structure ensures that the MBR technology has the advantages of high efficiency, small occupied area, good effluent quality and the like. However, due to the special nature of the wastewater, the viscosity of the sludge is high, the sludge is difficult to stir effectively in the traditional aeration mode, the sludge is easy to deposit on the surface of the membrane, the membrane flux and the operation efficiency are affected, secondly, the non-uniform aeration can cause dead zones in the membrane tank, the sludge in the dead zones cannot be stirred effectively, the precipitation risk is further increased, in addition, the high sludge concentration and viscosity can also cause the increase of aeration energy consumption and the difficulty in maintenance, and an active cleaning mechanism is lacked, so that the chemical cleaning period of the membrane assembly is shortened, the membrane wire breakage rate is increased, and the economical efficiency and the reliability of the MBR technology are seriously affected.
