There is no need to build a fixed pipeline, which not only hinders the operator's walking, but also lacks flexibility. The water hose is flexible and can be easily disassembled and stored. One water hose can correspond to multiple sewage pumps, reducing cost investment.
[0025] In one embodiment of the present invention, the sludge return pump room 2 is connected to the first sludge dewatering room 21, the sedimentation tank 1 is connected to the oxidation ditch 4, the oxidation ditch 4 is connected to the first grit tank 5, the first grit tank 5 is connected to the first fine screen tank 6, the first fine screen tank 6 is connected to the first sewage lift pump room 7, the first sewage lift pump room 7 is connected to the first coarse screen tank 8, the first coarse screen tank 8 is connected to the first water inlet tank 9, and the first water inlet tank 9 is provided with a plurality of flow channels, two of which flow to the two first coarse screen tanks 8 respectively. After the sewage sludge flows through the two first coarse screen tanks 8, it flows to the respective corresponding first sewage lift pump rooms 7, lifts the upstream water to the height required by the subsequent treatment unit, enables it to realize gravity flow, and then flows to its respective first fine screen tank 6. The first coarse screen tank 8 and the first fine screen tank 6 are mainly used to filter large amounts of sewage.

After treatment, it flows to the corresponding sedimentation tank 1, and then the sewage sludge is pumped into the biochemical pool 3 for reaction treatment through the sewage pump outside the sludge return pump room 2. The remaining sludge in the sludge return pump room 2 flows to the sludge dewatering room 21 for treatment and then transported outward. Some sludge that does not flow into the sludge dewatering room 21 flows back to the oxidation ditch 4 for recirculation.
