Abstract

The utility model relates to the technical field of rain and sewage diversion, and particularly discloses a pontoon type rain and sewage separator which comprises a tank body, wherein a baffle plate is fixed in the tank body and divides the tank body into a water outlet area and a rain water distinguishing area. When rainwater flows into the rainwater distinguishing area through the rainwater inlet pipe, the rainwater in the rainwater distinguishing area gradually accumulates to drive the pontoon to float, the pontoon floats to drive the connecting shaft and the sealing sheet to rotate, the sealing sheet seals the sewage outlet pipe when rotating, at the moment, the water re-accumulated in the rainwater distinguishing area flows into the water outlet area from the overflow groove and is conveyed into the pipeline for dredging the rainwater from the rainwater outlet pipe, and because the sewage outlet pipe is sealed, the rainwater at the top of the building is directly conveyed into the water outlet area when conveyed through the sewage inlet pipe and is conveyed into the pipeline for dredging the rainwater from the rainwater outlet pipe, so that the rainwater is guided into the ditch, and the influence on the sewage treatment plant when the rainwater is conveyed to the sewage treatment plant from the sewage outlet pipe is prevented.
