Residual sludge reduction treatment device

The utility model relates to the technical field of sludge treatment, and discloses a residual sludge reduction treatment device which comprises a reaction tank, one side of the reaction tank is fixedly communicated with a first sludge inlet pipe, a sludge inlet pump is fixedly mounted on the first sludge inlet pipe, one end of the first sludge inlet pipe is fixedly communicated with a crushing barrel, and a crushing assembly is mounted in the crushing barrel. The crushing assembly is driven by a first driving motor, the upper part of the crushing barrel is fixedly communicated with a second sludge inlet pipe, and the other side of the reaction tank is fixedly communicated with a sludge discharge pipe. Sludge enters the crushing barrel to be crushed before entering the reaction tank from the second sludge inlet pipe, sludge agglomerates in the sludge can be effectively crushed, the mounting plate can stir the sludge in the crushing barrel while the crushing blades crush the sludge, and the crushing efficiency
