Preferably, the branch passages are located on the same horizontal plane.

Preferably, the flat membrane module includes the bracing piece, the top of bracing piece is provided with filters the membrane frame, filter the bottom of membrane frame and install vibrating motor through the mount pad, one side of vibrating motor is provided with the outlet pipe, be provided with the solenoid valve on the outlet pipe, the one end of outlet pipe is provided with the ultrasonic wave vibrting spear through the fixing base.

Preferably, the upper surface of the flat membrane component is provided with a water collecting main pipe, the side surface of the flat membrane component is connected with a water collecting branch pipe, the bottom of the water collecting branch pipe is connected with an aeration pipe, and the side surface of the aeration pipe is uniformly distributed with air dispersing nozzles.

Preferably, the distribution channel is arranged along the periphery of the edge of the sewage treatment pool.

Preferably, the size of the wastewater treatment basin is 14 x 2.5 x 3 m.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a pipe or cell wall of pipe or cell body are equipped with a plurality of passageways that communicate with the main entrance that run through the wall thickness, the open end of a passageway is located in the sewage treatment pond, it is a plurality of the passageway is at body axial direction interval arrangement, has realized that the multiple spot is intake, has solved because the too big water distribution of membrane pool is inhomogeneous, prevents the high sewage treatment quality poor technical problem who causes of local region pollutant concentration.

Further, drive the vibrations of filtration membrane frame through vibrating motor, make the dirt of filtration membrane break away from the body and discharge outside the pipe, prevent that long-term use from making the filtration membrane blockked up, influence filtration rate.
