Sludge dewatering system

The utility model belongs to the technical field of sludge dewatering, concretely relates to sludge dewatering system, including flocculation reactor, dewatering device and extruding -desiccation machine in advance, flocculation reactor is last to have sludge inlet and an overflow mouth, and flocculating agent conveyer pipe, two bleeder sweetgum fruits of mud conveyer pipe are crossed total pipeline and are connected with sludge inlet, install the sludge pump on the mud conveyer pipe, the overflow mouth passes through pipeline and dewatering device's access connection in advance, and the feed inlet of extruding -desiccation machine corresponds the setting with dewatering device's export in advance. Through the cooperation of each unit among the whole sludge dewatering system, reduced the dehydration pressure of extruding -desiccation machine, promoted ultimate mud mass dryness fraction, reduced the subsequent processing degree of difficulty of mud, make mud and flocculating agent fully react through vortex reactor, reduced the quantity of flocculating agent, reduced sludge dewatering's cost, eliminate a large amount of free water through the rotary filtering machine, destroy lessly in the dehydration to wadding group, be favorable to the extrusion dehydration in later stage.
