A novel technology of preparation of felt-metal supported modified polyvinyl alcohol(PVA) ultrafiltration(UF) membrane was invented, which could avoid the blockage of the holes of support layer and the leakage of the casting solution through the holes of support layer. Felt-metal supported ferric sulfate modified PVA composite UF membranes were prepared by the innovative technology. The results show that the composite membranes are used to treat 1 000 mg/L oil/water emulsion at trans-membrane pressure from 0.25 to 0.45 MPa, the permeate flux is from 36 to 52 L/(m2 · h), and the retention of chemical oxygen demand(COD) is over 92%. The composite membrane resistance increases with the increase of trans-membrane pressure.
