A kind of cloths-PVA hydrophilic membrane was prepared using polyvinyl alcohol as coating material and terylene filter cloths as base material, which had high porosity rate and little resistance. The feasibly of treating oil/water emulsion was studied. This membrane was used to treat 1000mg/L O/W emulsion under the pressure of 0.05MPa, the permeate flux was about 140L/m2, h and the rejection of oil was about 82.3%.
