The clean water in the water tank 12 is used to backwash the ceramic membrane 221 through the backwashing unit 44 or the membrane units 22 are washed through the cooperation of the backwashing unit 44 and the air supply assembly 3. When only the backwashing unit 44 is used, when the pressure sensors on the water inlet side and the water production side of the ceramic membrane 221 monitor that the pressure difference reaches a preset threshold, that is, the pollutants attached to the surface of the ceramic membrane 221 or in the membrane holes reach a certain degree, the control assembly 5 automatically starts the backwashing program, instructs the fourth valve body 42 to switch the valve position, disconnects the normal water production channel between the water production main pipe 41 and the water tank 12, connects the backwashing circuit, transports the qualified clean water stored in the water tank 12 to the water production branch pipe 223 of each membrane unit 22 through the water production main pipe 41, and the reverse water flow flows from the water production side of the ceramic membrane 221, penetrates the membrane holes and then flows from the water inlet side. Under the action of the water flow impact force, the fine pollutants and clogging impurities attached to the inner wall of the membrane holes are washed and stripped. When the backwashing unit 44 and the air supply assembly 3 cooperate, the control assembly 5 can start the air supply assembly 3 first or start the backwashing unit 44 first. The air supplied by the air supply branch pipe 222 of the air supply assembly 3 is sprayed out of the ceramic membrane 221 in the reverse direction, forms micro bubbles in the membrane holes, and the impact force generated when the bubbles burst can strengthen the stripping of stubbornly attached pollutants or the bubbles released by the perforated aeration pipe 34 / aeration disc rise and wash the outer surface of the membrane. The backwashing unit 44 transports the qualified clean water stored in the water tank 12 to the water production branch pipe 223 of each membrane unit 22 through the water production main pipe 41, the reverse water flow flows from the water production side of the ceramic membrane 221, penetrates the membrane holes and then flows from the water inlet side, and under the action of the water flow impact force, the fine pollutants and clogging impurities attached to the inner wall of the membrane holes are washed and stripped.

A flow meter can be arranged on the backflush pipe 441 to facilitate control of the flow rate. When the pressure difference monitored by the pressure sensors on both sides of the ceramic membrane 221 reaches the preset threshold, the control assembly 5 automatically starts the backwashing program, instructs the fourth valve body 42 to switch the valve position, and disconnects the normal water production channel between the water production main pipe 41 and the clean water tank 12, and connects the backwashing circuit between the backflush pipe 441 and the water production main pipe 41 to provide a path for the reverse water flow. The backflush pump 442 is started to extract the qualified clean water stored at the bottom of the clean water tank 12, which is then transported to the water production main pipe 41 through the backflush pipe 441, and then branched to the water production branch pipes 223 of the membrane units 22 to form a stable reverse flushing water flow. The characteristics of the diaphragm pump can achieve smooth output of water flow pressure, avoiding the impact on the membrane caused by sudden pressure rise and fall. The flow meter on the backflush pipe 441 collects backwashing water flow data in real time and feeds back to the control assembly 5; the control assembly 5 dynamically adjusts the power of the backflush pump 442 according to the degree of pollution, that is, the size of the pressure difference, to accurately control the backwashing flow.

When the flow is small, the multiple membrane units 22 are divided into a water production group and a gas supply group, so that the first valve body 224 of the gas supply group is opened, and the ceramic membrane 221 of the membrane unit 22 forms an aeration effect while reducing the adhesion of pollutants on the surface of the ceramic membrane 221. The second valve body 225 of the water production group is opened, the ceramic membrane 221 of the membrane unit 22 filters the sewage in the aeration tank 11, and the purified water is transported to the clean water tank 12 through the water production branch pipe 223. The first valve body 224 and the second valve body 225 are controlled by the control assembly 5 to realize accurate start and stop of the aeration and water production processes. Part or all of the membranes in the water production group and the gas supply group can be rotated after a preset time or when a preset condition is met. When the flow is large, all the membrane units 22 produce water, and the perforated aeration pipe 34 or the aeration disc is started to ensure sufficient oxygen supply.
