Natural running water ozone ultrafiltration membrane water purification treatment method

The invention relates to a natural flowing water ozone ultrafiltration membrane water purification treatment method which is characterized by comprising the following steps: S1, injecting algae-containing self-flowing water into a coagulation tank, adding a flocculating agent into the coagulation tank, and reacting for a certain time to obtain a coagulation liquid; s2, the coagulated liquid enters a circulating slag removal box, a partition plate is arranged in the circulating slag removal box, the coagulated liquid forms vertical circulating flow in the circulating slag removal box, algae floating objects are discharged out of a slag discharging pipe, and sediment is discharged out of a bottom sludge discharging pipe; a clear liquid obtained after deslagging is mixed with ozone through a gas-liquid mixing pump to form a gas-water mixture; s3, the gas-water mixture is filtered by a self-cleaning filter and then enters an ultrafiltration membrane purifier; purified water filtered by the ultrafiltration membran
