Abstract：

In dyeing and printing wastewater treatment, how to efficiently separate dye/salt wastewater is an urgent problem. This project is to achieve efficient dye/salt selective separation and improve the membrane flux.Using polyvinylidene fluoride (PVDF) as the base membrane, carboxymethylcellulose (CMC) gel assisted by tannic acid was used to construct a stable gel layer through layer-by-layer cross-linking in order to reduce membrane contamination and improve the membrane flux, and then polymerised with polypyrrole on the surface of it in order to prepare a composite membrane to further improve the rejection rate.The microstructure, hydrophilicity, electrophilicity, dye/salt separation and operational stability of the membrane were investigated. The results showed that the membrane has high rejection of five typical dyes (>99%) and high flux to pure water [91.7 L/(m2·h)], and also has good dye/salt separation performance (dye rejection >99%, salt rejection <6%).
