Sludge reduction and degradation equipment in sewage treatment

The utility model discloses sludge reduction and degradation equipment in sewage treatment, which comprises a bottom plate, a sludge box is fixedly mounted at the top of the bottom plate, a hose penetrating through and extending into a degradation box is fixedly mounted on one side of the sludge box, the degradation box is fixedly mounted at the top of the bottom plate, and a motor is fixedly mounted on one side of the degradation box. According to the sludge reduction and degradation equipment in sewage treatment, the control valve is rotated to convey an active material of the active cylinder into the sludge box through the material pipe, then the water pump is started to pump sludge into the sludge box, the sludge is discharged from the sludge box through the material pipe, and the sludge is discharged from the sludge box through the material pipe. And at the moment, a motor is started, an output shaft of the motor rotates to drive a lead screw to rotate, a threaded ring is made to rotate, then a connectin
