NOVELTY - The utility model claims a aminated oxide graphene and graphite-phase carbon nitride composite modified film. polyamide skin layer of the composite modified membrane comprises polysulfone hollow fibre organic ultrafiltration membrane, distributed on the polysulfone hollow fibre organic ultrafiltration membrane on one side surface of the laminated structure and composite the polysulphone hollow fibre organic ultrafiltration film of the side surface of the laminated structure comprising aminated graphene oxide layers and nitride sheet. The utility model claims a composite modified membrane distribution sheet structure on the polysulfone hollow fibre organic ultrafiltration membrane, and then compounded with a layer of polyamide skin layer on the polysulfone hollow fibre organic ultrafiltration membrane, so as to form tight SL g-C3N4/NGO/ polyamide composite layer structure, greatly improving the hydrophilicity of the film surface, and greatly reduces the film functional layer of the forbidden band width (Eg) value, and has excellent visible light catalytic ability and catalyzing and degrading organic substance ability, and greatly improve the membrane flux. anti-pollution ability is obviously improved and the cost is low.
