When the device is implemented, wastewater is discharged into the water distribution pipe from the water inlet, the water distribution pipe distributes water uniformly, the wastewater is distributed into the filter cylinder, the wastewater enters the upper interlayer in the filter cylinder and then enters the middle interlayer through the input pipe. The wastewater is filtered by the filter membrane, and soluble metal ions and compounds in the wastewater are filtered out and filtered for multiple times under the combined action of the stock solution runner net, the concentration filter screen, the polyvinyl alcohol compact layer, the polypropylene membrane layer and the ion exchange membrane, so that the optimal effect of water purification is achieved. The surface of the polypropylene film layer is crosslinked with the polyvinyl alcohol compact layer, so that the surface hydrophilicity is obviously enhanced, and the pollution resistance of the surface is improved. The filtered water enters the lower interlayer from the output pipe, then is collected to the water outlet pipeline and is discharged from the water outlet. After the equipment runs for a period of time, the filtering capacity is reduced due to the blockage caused by impurities in the wastewater, the equipment stops running at the moment, the backwashing water inlet is opened, the filter element in the filter cylinder is backwashed by clean water, and washing liquid is discharged through the backwashing water outlet.
