When there is a lot of floating scum on the surface of the secondary sedimentation tank, by lowering the liquid level of the tank (opening the scum skimming valve 24), the floating scum on the liquid surface will automatically flow onto the scum skimming and water guiding plate 22, and the water and floating scum on the surface of the sedimentation tank 11 will flow along the scum skimming and water guiding plate 22 into the scum skimming pipe 23 and then be discharged outwards (the slag discharging time can be set in advance according to the sewage properties and treatment scale, and is automatically controlled by the background and regularly discharged automatically). After the slag discharging is completed, the scum skimming valve 24 is powered off and closed. When the water level of the sedimentation tank 11 rises, it discharges water normally along the first water outlet 14.

When the water level of the sedimentation tank 11 rises to the normal water level, the water will flow into the water outlet weir frame 31 through the third water outlet 33 and then be discharged normally through the first water outlet 14 (the first water outlet 14 is slightly lower than the L-shaped horizontal end of the water outlet weir frame 31).
