A kind of integrated treatment method of sludge in drainage pipe network

Abstract

The invention discloses an integrated treatment method for drainage pipe network sludge, which includes a sludge excavation step and a sludge-water separation step; the sludge excavation step includes: a preliminary sludge cleaning step, a deep sludge cleaning step, and an over-thick sludge The cleaning step, the cleaning step of large stones or obstacles, the mud-water separation step includes: the initial stirring step, the re-stirring step, and the screw conveying step; the initial stirring step and the re-stirring step also include the step of adding a sludge curing agent . By applying the method, sludge excavation and sludge treatment can be realized at the construction site at the same time, and the whole process is safe, efficient, clean and environmentally friendly, greatly improving the operating efficiency, and simultaneously reducing operating costs and labor intensity of workers.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to an integrated treatment method for drainage pipe network sludge. Background technique [0002] During the flood season every year, due to the sludge accumulation in the drainage pipe network, the smooth drainage is affected. After the heavy rain, more and more cities will experience serious water accumulation on the road surface caused by the sludge accumulation in the urban drainage pipe network, which may even lead to traffic congestion in this section of the road. Interruption has seriously affected people's life and production. Therefore, the underground drainage pipe network needs to be cleaned regularly. Conventional circular drainage pipes have special maintenance equipment. The dredging of box culverts is generally carried out by manual dredging. However, manual dredging requires interception, drainage, and exhaust, and is inefficient. The ma...

Problems solved by technology

[0002] During the flood season every year, due to the sludge silt in the drainage pipe network affecting the smooth drainage, more and more cities will experience serious water accumulation on the road surface caused by the sludge silt in the urban drainage pipe network after the heavy rain, which even leads to traffic congestion in this section of the road. interrupted, seriously affecting people's life and production

Therefore, the underground drainage pipe network needs to be cleaned regularly. Conventional circular drainage pipes have special maintenance equipment. The dredging of box culverts is generally carried out by manual dredging. However, manual dredging requires interception, drainage, and exhaust, and is inefficient. The main thing is not safe

In addition, the collected sludge often contains a lot of water, which is not convenient for transportation and subsequent disposal, and often fails to meet the relevant requirements of current environmental protection regulations.
