In order to maintain a certain membrane flux and prolong the service life of the membrane component, the ultrafiltration system stops filtering and carries out periodic backwashing. The backwashing process is to reversely permeate the ultrafiltration produced water or tap water through the hollow fiber membrane and scrub the surface of the hollow fiber membrane filaments to remove sediments. After backwashing is started, the water inlet adjusting valve 25 is closed, the water suction pump 39 continues to operate, the cleaning agent adjusting valve 53, the water injector 54 and the tap water connection adjusting valve 56 are opened, so that after the water suction pump 39 sucks the purified water in the water collecting tank 48, the purified water is mixed with a cleaning agent in a certain proportion when water is discharged, the cleaning agent and the cleaning agent enter the membrane reversely through the water suction pipe multifunctional medium pump 40, after the membrane is soaked for a short time, backwashing water enters the ultrafiltration fibers from the clear liquid side and flows to the concentrated water side through the membrane, pollutants on the surfaces of membrane pore passages and the curtain type ultrafiltration membrane are washed away through large-flow backwashing water, and the washed pollutants are discharged through the emptying pipe 60 and the adjusting valve 61.
