However, with the increase of the service life of the membrane equipment, when the pressure of the water inlet pressure gauge 4 is increased to 0.3Mpa, gas backwashing is required, and the specific operation process is that the water inlet valve 3 and the water inlet pump 2 are kept in an open state, the water outlet valve 6 is closed, the gas washing valve 8 is opened, then the gas washing fan 10 is opened, the gas washing pressure gauge 9 is controlled to be smaller than 0.1Mpa in the gas washing process, and gas washing is stopped when suspended substances SS of water inlet and water outlet are felt to be almost in a macroscopic state, and the gas washing process is generally considered to last for 10-20 s.

The stone processing sewage integrated treatment device adopts main equipment such as a water inlet pump 2, a macroporous membrane device 5, an air washing blower 10, a water washing pump 12 and the like. The production of the phenomena can be avoided by combining a sewage collecting tank, a water inlet pump 2 room, a vertical flow sedimentation tank, a horizontal flow sedimentation tank, a sewage regulating tank, a plate and frame sludge regulating tank, a plate and frame filter press, a sludge centrifugal regulating tank, a sludge centrifugal machine and the like and combining the process steps shown in the figure 3.
