The invention discloses an integrated sewage treatment device and method. The device comprises a reaction bin, a driving motor is arranged at the top of the reaction bin, the output end of the drivingmotor is fixedly connected with a coupler, the bottom of the coupler is fixedly connected with a rotating rod, the bottom of the rotating rod penetrates through the reaction bin and is movably connected with a bearing, and the bottom of the bearing is fixedly connected with the joint of the reaction bin. Through arrangement of the reaction bin, a first water pump, a sedimentation tank, a filtering bin, a second water pump, a first electromagnetic valve, a second electromagnetic valve, a stirring plate, a rotating rod, a driving motor and a third water pump, the device can achieve the functionof the high device use rationalization degree, and solves the problems that the existing sewage treatment operation continuity is not strong, the device utilization rate is different, the device input amount is large, the cost is increased, and the treatment efficiency cannot meet the use requirements because the operation time of each stage of the sewage is difficult to coordinate and the operation time of each process is different.
