Sludge dewatering device for water supply and drainage

The invention discloses a sludge dewatering device for water supply and drainage, and relates to the technical field of sludge treatment for water supply and drainage. Comprising a rack, a discharging frame is fixedly installed on the surface of the bottom end in the rack, a collecting hopper is fixedly installed on the surface of the top end of the rack, a box is arranged at the lower end of the collecting hopper, a rotating disc is arranged in the box, and a mounting box is arranged at the lower end of the rotating disc. According to the sludge dewatering device, sludge can be stirred and mixed before formal dewatering operation through the arranged aggregate bin assembly structure, so that the situation that impurity particles are different in size and uneven in concentration is avoided, meanwhile, a part of water is conveniently separated out, and the subsequent dewatering time is shortened; after the sludge is lifted to a certain height, a gap between the sludge and the dewatering net is controlled by ut
