Then the staff puts flocculant through the delivery port 7 to flocculate and precipitate the remaining impurities in the wastewater. The treated water first passes through the filter screen 20 to filter the sediment, and then passes through the activated carbon plate 21 to further adsorb small particles of debris. Then the treated water is pumped back into the water tank 1 through the pump 9 to complete the water recycling.

[0026] Furthermore, the rotating motor 4 is arranged at one end of the cylinder frame 3, and the output end of the rotating motor 4 is connected to an output shaft 22 extending to the other end of the cylinder frame 3.

The surface and inner wall of the drum 6 are respectively provided with water through holes and rotary blades 17; the rotating motor 4 drives the device to work, and the water through holes on the surface of the drum 6 are convenient for the water from the water tank 1 to enter the drum 6, and secondly, it is convenient for the waste water at the bottom to pass through and fall into the water filter bin 11 after cleaning.

[0027] Furthermore, the dense mesh sieve plate and the bottom of the water filter bin 11 are both sloped, and the water filter bin 11 is divided into an upper and lower layer by the dense mesh sieve plate, and the lower end side of the upper layer is open and the lower end side of the lower layer is closed, and the water outlet 6 is arranged on the lower end side; the wastewater in the drum 6 falls into the water filter bin 11, and the wastewater is first screened by the dense mesh sieve plate, and the large particles of debris after screening slide along the slope, and the water flow falls into the water outlet 6.

[0028] Furthermore, a cover plate 18 is provided on the top of the recovery box 8, and a delivery port 7 is provided on the side of the top of the cover plate 18 near the water outlet 6. A water inlet is opened on the surface of the cover plate 18 at a position corresponding to the water outlet 6, and a filter screen 20 is provided inside the partition near the water inlet, and an activated carbon plate 21 is provided inside the partition away from the water inlet. The connection position of the return pipe 12 is located on one side of the partition away from the water inlet; the two partitions can divide the recovery box 8 into three sections: front, middle and rear. After passing through the water outlet 6, the water flows through the water inlet and then falls into the front section of the recovery box 8. Then the staff delivers flocculant through the delivery port 7 to flocculate and precipitate the remaining impurities in the wastewater. The treated water first passes through the filter screen 20 to reach the middle section, and then passes through the activated carbon plate 21 to reach the rear section, and then the treated water is pumped back into the water tank 1 by the water pump 9.

[0029] Furthermore, a water filling port 14 is provided on the top of the water tank 1 to facilitate water filling.
