The invention discloses a
wastewater treatment device with a multi-level multi-particle
diameter circulation smashing device. The
wastewater treatment device comprises a device body, a motor, a through
pipe, the multi-level multi-particle-
diameter smashing device, a disintegrating
slag collection device, a through water pipeline, a connecting
pipe, a first filter plate, a second filter plate, a water tank, a pressure pump, a water outlet hole and a water inlet hole, the motor is fixedly mounted at the top of the device body, the through
pipe is fixedly connected with the top of an inner cavity of the device body, the multi-level multi-particle-
diameter smashing device is arranged at the bottom end of the through pipe, and the bottom of the multi-level multi-particle-diameter smashing device is connected with the disintegrating
slag collection device. By the aid of the multi-level multi-particle-diameter smashing device and the disintegrating
slag collection device, large-particle pollutants are effectively smashed and stored, blockage of the device caused by the large-particle pollutants is avoided, the device is conveniently installed and cleaned, manual labor intensity is reduced, smashed pollutants can be directly taken out by the aid of a connecting rod and a pulling plate, and the pollutants are conveniently treated.
