[0019] 1. The user connects the water inlet pipe with the tail water treatment pipe, so that the tail water is discharged into the filter barrel through the water inlet pipe, and the filter barrel filters the tail water debris. The filtered water is then discharged through the discharge pipe, so that the debris is collected in the filter barrel. The user opens the control valve 2 to discharge the debris through the sewage pipe, so that the debris can be effectively discharged;

[0020] 2. The user connects control valve 1 with the high-pressure water pipe, and then opens control valve 1 to allow clean water to flow into the interior of the nozzle through the curved pipe, and then the water is sprayed out through the nozzle by pressure, thereby effectively and quickly cleaning the interior of the filter barrel.
