The mud scraper connected to the scraper arm rotates with the scraper arm and scrapes together the inert sludge settled at the bottom of the sedimentation tank so as to be discharged together. The mud is scraped into the central mud pit, and the inert sludge can be discharged from the inert sludge discharge pipe by using water pressure; the activated sludge suction pipe connected to the scraper arm rotates with the scraper arm and absorbs the sludge settled in the middle of the sedimentation tank into the activated sludge storage tank, and then use water pressure to discharge the activated sludge from the active sludge discharge pipe; when the working bridge and the scraper arm rotate, the scum scraper set on the connecting bracket connecting the working bridge and the scraper arm will settle The scum on the surface of the pool is scraped together.

The utility model has the following advantages and beneficial effects: the driving device of the utility model is connected with a working bridge, the working bridge is connected with the scraper arm, and the lower end surface of the scraper arm is connected with a mud scraper and an activated sludge suction pipe. When rotating along the sedimentation tank, the scraper and the activated sludge suction pipe work at the same time, the scraper scrapes the inert sludge at the bottom of the sedimentation tank, and the activated sludge suction pipe collects the activated sludge in the middle of the sedimentation tank. The utility model has a simple overall structure and is easy to realize, and simultaneously and separately collects activated sludge and inert sludge, and has low power consumption.
