Most of the commercial nanofiltration membranes are composite nanofiltration membranes obtained by interfacial polymerization of polyamines and polyacid chlorides on ultrafiltration membranes with non-woven fabrics. During the operation of the membrane, membrane fouling is caused by inorganic salt scale, colloid, organic matter and other factors in the environment, resulting in a decrease in water quality and water flux so that a significant reduction in membrane life and an increase in operating costs. Therefore, it is necessary to improve the pollution resistance of the film. The hydrophilic modification of the membrane can improve the anti-pollution performance of the membrane. This paper discusses the preparation and research progress of the hydrophilic composite nanofiltration membrane from three aspects: new monomer development, active layer modification and new base film development and the current research content is summarized and some of the contents that need urgent research are proposed.
