Abstract

The invention discloses a pressure-filtration electro-osmotic dewatering mechanism provided with a flocculating agent dropping device. The pressure-filtration electro-osmotic dewatering mechanism comprises the flocculating agent dropping device, a flocculating agent adding port, a motor, a sludge outlet, a belt drive unit, a rotating shaft, stirring blades, a flocculating agent outlet, a sludge storage tank, a screw pump, a pressure filter, a hydraulic device, hydraulic rods, filter discs, a sludge inlet pipe, a pressure filter water outlet, a sludge squeeze channel, a first transmission chain, a cathode filter screen, a wastewater tray, first chain wheels, an annular upper guide rail, a second transmission chain, a pressure device, second chain wheels, an anode plate, a sludge cake outlet, a sludge cake conveyer, delivery rollers, a conveyor belt, a conveyor belt motor, a continuous-current plant, a first continuous-current plant, a second continuous-current plant, and an annular lower guide rail; wherein the upper end of the flocculating agent dropping device is provided with the flocculating agent adding port. Electroosmosis efficiency is improved as far as possible; sludge processing efficiency is high; and processing quality is high.

Description

technical field [0001] The invention relates to the technical field of sludge dewatering equipment in the water treatment industry, in particular to a pressure filter electroosmotic dewatering mechanism with a flocculant feeding device. Background technique [0002] At present, sludge dehydration is an extremely important link in the sewage treatment process. This link needs to complete two processing tasks: the sedimentation sludge in the sewage that has completed the harmless treatment is separated, and the moisture content of the preliminary separated sludge is as high as 99. ﹪, it must be dehydrated and reduced, and the volume of the sludge after dehydration and reduced is greatly reduced, so as to facilitate the follow-up projects such as landfill and incineration of the sludge. Generally speaking, the water content of the sludge after dehydration and reduction is about 80%, and it is in the state of mud cake, and the volume is reduced to 20-30% of the original. The sl...
