Membrane separation technology has been widely used in the treatment of dyeing and printing wastewater for the selective separation of dye/salt mixtures. However, the current low commercial membrane flux and inevitable fouling issues greatly reduce the treatment efficiency. In this study, tannic acid (TA) surface functionalization and etching were used to prepare TA@MIL-53(Fe) powder with hydrophilicity and photocatalytic activity. The photocatalytic active material was introduced into the polyamide (PA) selective layer through vacuum filtration-assisted technology to prepare a new high-flux self-cleaning composite membrane. The effects of the material on the composite membrane and the photocatalytic self-cleaning mechanism were characterized by SEM, AFM, FTIR, and UV-vis. The results showed that when the addition of TA@MIL-53(Fe) was 0.02 wt%, the performance of the composite membrane was optimal, with a flux of up to 64.2 L·m-2·h-1·bar-1, and the dye retention rates for MB and TB were both above 95%. At the same time, the prepared membrane had a low removal rate for salts. In addition, compared with the flux recovery rate (FRR) of the membrane after hydraulic cleaning, the FRR of the MPTA-0.02 composite membrane after photocatalytic self-cleaning reached 96.5%. Meanwhile, the MPTA-0.02 composite membrane exhibited good self-cleaning performance and long-term stability. This provides a new approach for the development of dye/salt separation membranes with excellent fouling resistance
