The invention discloses a preparation method and application of a photocatalytic sewage treatment membrane, and relates to the technical field of sewage treatment. The preparation method of the photocatalytic sewage treatment membrane comprises, by means of vacuum suction filtration, modifying 8-mercaptoguanosine-polydopamine modified g-C 3 N 4 and/or 5-mercaptouracil-polydopamine modified Then, it can be filtered on the cellulose acetate membrane with g-C 3 N 4 . The photocatalytic sewage treatment membrane prepared by the invention has excellent membrane flux, improves the retention of organic pollutants, enhances the degradation of organic pollutants under the condition of visible light, effectively prevents the problem of membrane fouling, and improves the membrane flux , to enhance the membrane separation performance, especially in oil-water separation, it has excellent separation effect, and has great application prospects in water purification treatment. |
