Abstract:The domestic municipal sludge due to the historical problems of temporary film closed stacking problems is common. In a temporary sludge storage area, the sludge needs to be taken out for drying treatment and then sent to the power plant for incineration in order to solve the environmental problems and restore the land use function of the temporary storage site. In the process of sludge taking, it is easy to cause the secondary pollution and the operation safety problems due to odor leakage. With the closed suction technology, the sludge can be pumped to the sludge drying equipment in a fully closed state. The most of sludge can be suctioned out of storage area through the traction to realize the movement of the sludge suction device under the film. The cleaning operation will be carried out immediately after the completion of suction until all the sludge in the storage area is removed. Through the practical verification, the suction storage technology has the advantages of high speed, environmental protection and controllable sludge moisture content compared with the conventional sludge digging technology, which can be referred for the similar projects.
