Description

Dredging sludge system

Technical Field

The utility model relates to a ditch mud technical field specifically is a ditch mud system.

Background

The sludge for dredging the channel is the sediment sludge dredged and fished out in the drainage pipeline maintenance, is the sediment dredged and fished out in the drainage pipeline maintenance, has complex characteristics, and is a mixture of household garbage, muck, sand stone, organic sludge and sewage. If the sludge in the through ditch in the urban pipe network is not cleaned in time, the problems that drainage of a drainage pipeline is not smooth and accumulated water and sewage overflow are caused easily are caused, the sludge deposited in the pipeline enters a river channel along with rainwater in a rainy day to cause serious pollution events, and the harm is great.

Along with the increasing attention paid to the maintenance work of drainage pipelines, the amount of sludge in the channels is increased. Storage and disposal of a large amount of sludge are troublesome problems. The current method is to adopt temporary disposal of drying in the nearby green land after cleaning and then directly sending into the landfill site for landfill, which not only affects the environment of the green land around the pipe network, but also refuses to receive the partial sludge gradually because of complex components and large change of water content. With the continuous construction of urban pipe networks, the daily amount and yield of sludge will be greatly increased, the treatment contradiction caused by the increase is further aggravated, and the search for new sludge treatment measures is urgent.

Therefore, how to design a ditch sludge system becomes a problem to be solved currently.
