Technical Field

[0001] The utility model relates to a recovery device for an ABF membrane bioreactor, belonging to the technical field of ABF membrane bioreactors. Background Art

[0002] ABF membrane bioreactor (MBR) is a new sewage treatment technology that combines membrane separation technology and biological treatment technology. It filters the mixed liquid in the bioreactor through membrane components to achieve mud-water separation and improve the effluent quality of sewage treatment. Compared with the traditional activated sludge method, MBR has better mud-water separation effect and higher pollutant removal efficiency. The effluent water quality is excellent and stable and can be directly reused or discharged.

[0003] Before sewage enters the ABF membrane bioreactor for treatment, it first needs to be pretreated to remove large particles of impurities to prevent clogging of the membrane components. However, existing treatment devices generally only filter large particles of impurities in sewage through filtering devices, and the treatment effect is poor. In addition, it is not convenient to uniformly recover the large particles of impurities in the sewage after being processed by the filtering device, which reduces the practicality of the device.

[0004] Therefore, a recovery device for ABF membrane bioreactor is proposed. Utility Model Content
