The invention discloses a high-dryness sludge treatment machine which is compact in structure and is capable of realizing high-dryness sludge discharging. The high-dryness sludge treatment machine comprises an ultrasonic conditioning tank, a drum thickener, a multi-section type S-shaped pressurizing dehydrater and an electroendosmosis dehydrater, which are connected in sequence, wherein a stirrer and an ultrasonic reactor are arranged in the ultrasonic conditioning tank; the drum thickener comprises a drum; the drum is arranged in a drum box body; the surface of the drum is coated with drum screen cloth; the drum screen cloth is a polyester fiber net with the porosity of 40 meshes; a drum sludge inlet pipe and a drum sludge outlet pipe are arranged on the drum box body; the ultrasonic conditioning tank is connected with the drum thickener through the drum sludge inlet pipe; the drum thickener is connected with the multi-section type S-shaped pressurizing dehydrater through the drum sludge outlet pipe; the multi-section type S-shaped pressurizing dehydrater is connected with the electroendosmosis dehydrater. According to the high-dryness sludge treatment machine disclosed by the invention, five treatment means of chemical flocculation, ultrasonic conditioning, drum thickening, belt type extruding dehydration and electroendosmosis dehydration are integrated; the water content rate of treated sludge is below 60 percent.
Description
technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a high-dryness sludge treatment machine capable of realizing high-dryness sludge discharge. Background technique [0002] Sludge treatment is a new topic in sewage treatment and environmental improvement. The dewatering machines used in traditional sewage plants are mainly old-fashioned belt-type thickening and dehydrating machines, most of which are open structures, with poor operating environment and large structures. The moisture content of dehydrated sludge is generally high, and most of them exceed the international requirement of 80% moisture content. Requirements, resulting in high energy consumption for subsequent drying of the product. In order to improve the dehydration efficiency, in the prior art, the rotary drum thickening dehydrator and the belt press dehydrator are connected together for sludge treatment, and the dehydration effect of the sludge has been ...
