Drainpipe net sludge integrated treatment method

Abstract

The invention discloses a drainpipe net sludge integrated treatment method. The method comprises sludge excavation and sludge-water separation. The sludge excavation process comprises sludge primary cleaning, sludge deep cleaning, over-thick sludge cleaning and large-block stone or barrier cleaning. The sludge-water separation process comprises primary stirring, re-stirring and spiral delivery. The primary stirring and re-stirring processes comprise sludge curing agent addition processes. The method synchronously realizes sludge excavation and treatment on construction scene, is safe and effective in the whole process, is clean and environmentally friendly, greatly improves work efficiency and reduces a work cost and labor intensity.

Description

Technical field [0001] The invention belongs to the technical field of environmental protection, and specifically relates to an integrated treatment method for sludge in a drainage pipe network. Background technique [0002] During the flood season every year, due to the sludge siltation of the drainage pipe network affecting the smooth drainage, after heavy rains, more and more cities will experience serious water accumulation on the road surface caused by the sludge siltation of the urban drainage pipe network, which may even lead to traffic on the road section. The interruption has severely affected people's lives 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 the efficiency is low. The main thing is insecurity...

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.
