Abstract

The invention relates to a municipal sludge dewatering and curing method, and relates to the field of sludge treatment. The method comprises the following steps: S1, stirring: pumping sludge into a box body, and stirring through a stirring device; S2, pumping the coagulated and uniformly stirred sludge into a mud-water separation box, adding a flocculating agent into the mud-water separation box, and stirring the sludge to form pasty slurry; S3, filter-pressing: carrying out filter pressing on the stirred pasty slurry through a plate-and-frame filter press, so as to filter-press the sludge into a mud cake; and S4, crushing: crushing the mud cake through a crusher so as to enable the mud cake to become powder. In step S1, when the sludge is stirred, a smashing device is arranged in the box body, and the caked sludge is smashed through the smashing device. The method has the effect of ensuring sufficient stirring of sludge, so that the working efficiency of sludge curing is improved.

Description

technical field [0001] The present application relates to the field of sludge treatment, in particular to a municipal sludge dehydration and solidification method. Background technique [0002] At present, municipal silt refers to the muddy waste generated in the process of urban construction and public facilities maintenance. This kind of waste directly enters the urban drainage system and rivers, which will seriously affect the drainage function of the city due to the deposition of solid particles. The release of pollutants endangers the urban environment. The usual Sinotrans push and release not only causes waste of land resources but also affects the quality of the surrounding environment. [0003] The existing patent application number is the Chinese patent of CN202011643515.5, which proposes a method for dehydrating and solidifying reservoir silt, which includes the following steps: S1, setting up a cofferdam in the reservoir, the cofferdam closes part of the waterway...
