The invention discloses an efficient sewage treatment method based on an MBR (Membrane Bioreactor) membrane. The method comprises the following steps: carrying out sludge precipitation after sewage passes through a grid plate (12) in an adjusting tank (1); enabling the sewage to enter a facultative tank (2) through a three-way solenoid valve (14); when the temperature of the sewage in the facultative tank (2) is relatively high, enabling the sewage in the adjusting tank (1) to flow into the facultative tank (2) through an underground cooling pipe (15); when the temperature of the sewage in the facultative tank (2) is relatively low, controlling the three-way solenoid valve (14) to enable the sewage in the adjusting tank (1) to pass through a heating water tank (16) and flow into the facultative tank (2); driving a wind power driving rod (8) by a wind power impeller (7) to rotate, and driving two driven gears (42) through a driving gear (46); driving two MBR membrane bodies by the driven gears (42) to rotate and move; forming pressure difference by the sewage between an upper membrane layer (411) and a lower membrane layer (412), so as to improve the filtering efficiency; after purifying, discharging the sewage through a water drainage pipe (26); meanwhile, driving an aeration wheel (9) to rotate incessantly along with the wind power driving rod (8), so as to enlarge the aeration area and improve the utilization rate of equipment.
