The invention discloses a pretreatment device for wastewater reuse. The device comprises a shell, wherein a water inlet is formed at the upper end of the shell; a water draining pipe is arranged at the lower end of the shell; a reflux device is arranged on the water draining pipe; a second filtering film is arranged in the water draining pipe; a motor and a control switch are arranged on the upper surface of the shell; the motor is electrically connected with the control switch. The pretreatment device for wastewater reuse firstly treats the wastewater in the manner of multi-level filtering, can save time for the subsequent wastewater treatment and can prolong the service life of the related device in the subsequent treatment link; a sewage draining port which is capable of being manually opened and closed is formed on the device; the sewage draining port is under a closed state in a filtering process, so that the sewage can be more sufficiently filtered; the sludge in the sewage can be discharged after the filtering is ended, so that the preparation for the filtering at the next time can be made; a stirring device is arranged for continuously stirring the wastewater in a filtering process, preventing wastewater lamination and blocking, so that the filtering efficiency is increased; the reflux device is arranged for further increasing the efficiency of wastewater treatment.
