The method is characterized in that: the pumping mode adopts a non-clogging submersible sewage pump to lift sludge, and the sludge-lifting submersible sewage pump has the characteristics of no clogging, low noise, low energy consumption, convenience in installation and maintenance and the like. The sedimentation tank can be provided with a plurality of longitudinal drainage grooves or drainage pipes; the siphon mode adopts a vacuum pump to form vacuum, and is simple and reliable; the walking mode is a track mode, and the program controls the all-weather timing start of the mud scraper. After the activated sludge scraper is started, the walking speed of the sludge scraper can be controlled according to the distance between the horizontal flow sedimentation tank and the flocculation tank, and the activated sludge at the bottom of the tank can be more effectively extracted.

The driving device is a PLC controlled electric cabinet, a frequency converter is configured to control the speed of the walking motor, and the walking direction and the distance from the flocculation tank are judged by a program. The horizontal flow sedimentation tank is divided into 4 subareas. The part close to the flocculation tank is a head part, and the head part has the most active sludge and can move slowly (operate at low frequency speed), so that the mud scraper can have enough time to suck out bottom sludge at the part. The part close to the head subarea is a slow subarea, the part has more sludge and the walking speed is controlled to be operated at a medium and slow speed frequency. The slow speed partition is a constant speed partition, the part of sludge layer is not thick, and the part of sludge layer can be quickly sucked up by operating at a medium speed. The tail part of the horizontal sedimentation tank is a rapid subarea, the sludge is less, and the mud scraper can rapidly operate the section and return to an area with more sludge layers, so that the sludge is accelerated to be extracted. This operational mode can reduce the number of times that the mud scraper made a round trip to walk for the row's mud speed of sedimentation tank, the water yield of discharge and the electric quantity of mud scraper operation simultaneously when more can practicing thrift the silt of taking out.
