Abstract

Embodiments herein relate to a membrane bioreactor for strengthening membrane fouling control and method thereof. The embodiments may solve problems associated with existing techniques in the field of water treatment. The membrane bioreactor may include a reactor wall, a membrane element, a collecting pipe, a water collecting pipe, a vacuum table, a suction pump, a cleaning unit, an air compressor, an aeration pipe, an aeration head, an inlet pipe, and a drain pipe. The existing techniques related to membrane fouling control has problems such as complexity to operate, difficulties to clean online, and uses of chemicals, which may cause secondary pollution. The embodiments relate to a device that includes a set of automatic mechanical transmission units. With cleaning parts installed at terminals of the device, the surface of the pollution layer of the flat membrane may be cleaned periodically to achieve in situ membrane fouling control, an increase of water production capacity and backwash cycle, and improvement of the efficiency of the membrane bioreactor.
