Abstract

The invention discloses a rapid sludge dewatering system and a dewatering method, and belongs to the technical field of sludge dewatering. The sludge rapid dehydration system comprises a dehydration auxiliary agent tank, a sludge activation stirring device, a filter pressing device, an extrusion granulation device and a drying device, the drying device comprises a machine shell, and the interior of the machine shell is divided into an upper space and a lower space through a breathable conveying belt horizontally distributed in the length direction of the machine shell; wherein the upper spaceis divided into a plurality of air entraining channels through an upper partition baffle, the lower space is divided into a plurality of air entraining channels through a lower partition baffle, and air enters through an air inlet in one end of the machine shell and then sequentially and alternately enters the lower air entraining channels and the upper air entraining channels. By the adoption ofthe scheme, sludge can be dewatered rapidly and efficiently, deep dewatering of the sludge is achieved, the application process is easy to operate, and energy consumption is low.

Description

technical field

[0001] The invention belongs to the technical field of sludge dewatering, in particular to a rapid sludge dewatering system and a dewatering method. Background technique

[0002] Sludge (printing and dyeing sludge, coal washing sludge, urban surplus sludge, waste paper papermaking sludge, etc.) is a sediment formed by the migration, transformation, and precipitation of substances in water during the purification process of domestic sewage and industrial wastewater. Or the bottom mud deposited by suspended matter in the water body. Therefore, sludge is a solid waste (actually a semi-solid waste) formed with the purification of various types of water. The characteristics of sludge are high water content (moisture content ≥ 80%), large volume, high organic matter content, various metal elements, fine particles, poor air permeability, and a large number of active microorganisms. It will cause serious secondary pollution to the environment. The cost of sludge t...
