An integrated abrasion-resisting sludge muck treatment device is mainly suitable for treating mud sand excavated from urban construction and at least comprises a grinding part and a mud and sand separating part. Grinding pieces on the inner wall of a roller of the grinding part primarily crush treated mud sand entering the grinding part, the mud sand is sent to the mud and sand separating part, high-pressure dilution water nozzles are arranged on the outer side of the mud and sand separating part and dilute the mud sand entering the material separating part into dilute mud sand, and the dilute mud sand mixture with the particle size smaller than the large material preset particle size is allowed to pass through the mud and sand separating part; and the large material mixture with the particle size larger than or equal to the large material preset particle size is discharged from a discharging port. The grinding pieces are made of flaky materials into the regular geometrical shape. Due to the fact that the roller type mud and sand separating device is adopted in the device to treat the treated mud sand into dilute mud sand and the large material mixture, waste mud pulled by a mud truck from the construction site can be directly poured into the separating device and is rapidly treated into the dilute mud sand and the large material mixture, and accumulation cannot be caused.
