Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage, in particular to a normalized silt removal device. Background Art

[0002] At present, the urban drainage system is still mainly based on combined rainwater and sewage. The drainage pipe network system in the combined rainwater and sewage system can collect domestic sewage, industrial wastewater and rainwater (referred to as rainwater and sewage) at the same time. Rainwater and sewage are transported to the sewage treatment plant through the pipe network system, and then discharged into the receiving water body or nature after treatment.

[0003] In the dry season, sewage is intercepted and sent to the sewage treatment plant, and in the rainy season, excess rainwater and sewage overflow and are discharged into the water body. For the combined rainwater and sewage drainage network, due to the low flow rate on sunny days, a large amount of pollutants will be deposited in the network, and on rainy days, the deposited pollutants will be washed into the water body. In addition, the pollutants generated by rainwater washing the ground and the overflowing sewage will cause overflow pollution to the receiving water body.

[0004] Therefore, the most urgent problems to be solved today are the overflow pollution of drainage pipes in the rainy season, the black and smelly problems at the outlet end after the rainy season, and the problem that some pipeline inspection wells are set in the middle of the road, making maintenance inconvenient.

The silt crushing and flushing unit includes a sludge crusher and a high-pressure flushing gun controlled and operated by a water supply and power supply unit. The hanging bracket is suspended on the chain-type guide rail and moves along the chain-type guide rail in the inspection well and drainage pipeline. The silt crushed and flushed by the silt crushing and flushing unit is transported to the ground outside the inspection well by a sludge suction and mud collection truck.

[0006] The invention patent with publication number CN114534321A provides a pool sludge sweeping and suction cleaning device.
