After the industrial wastewater enters the tank body 1 through the water inlet pipe 3, the valves on the multiple shunt pipes 14 are opened, and then the industrial wastewater can be shunted into the multiple filter bags 15 to be filtered by the multiple filter bags 15. The filtered liquid is discharged from the water outlet pipe 4. After the filter bags 15 are used for a long time, some solid impurities will remain inside. At this time, a cleaning liquid (which can be pure water or other media) can be added to the water tank 6 first. The pump body 7 is driven to operate electrically (the pump body 7 is powered by external power facilities). The cleaning liquid in the water tank 6 is pumped out by the water extraction pipe 8, and the cleaning liquid is shunted from the multiple slender pipes 10 on the external pipe 9 and dispersed in the water inlet pipe 3 through the multiple nozzles 12. Then the cleaning liquid enters the multiple filter bags 15 through the multiple shunt pipes 14. Subsequently, the multiple servo motors 17 are driven to operate to drive the inner support shaft 18 and the inner stirring blades 19 thereon to rotate uniformly, continuously stirring the cleaning liquid in the multiple filter bags 15, so that the cleaning liquid reacts more closely with the filter bags 15, thereby accelerating the cleaning of the filter bags 15 and completing the self-cleaning of the filter bags 15.
