随着纺织产业的兴起，印染废水的治理问题已成为行内关注的热点，其关键是如何高效分离有机染料和无机盐。疏松纳滤膜因其疏松的膜结构，在实现高染料截留率的同时具有良好的盐渗透性，在印染废水的治理方面具有独特优势。针对印染废水的治理问题，着重综述了近年来采用相转化法制备疏松纳滤膜的研究进展，研究了纳米材料改性对所制备疏松纳滤膜性能的影响,并对其存在的问题进行深入分析，以及对未来采用相转化法制备疏松纳滤膜的研究方向进行了展望。

With the rise of the textile industry, the treatment of printing and dyeing wastewater has grown up to be a hot spot in the industry. The key is how to efficiently separate organic dyes and inorganic salts. Due to its loose membrane structure, the loose nanofiltration membrane has a high dye rejection rate and good salt permeability, which has unique advantages in the treatment of printing and dyeing wastewater. Article focuses on the research progress in the preparation of loose nanofiltration membranes by phase inversion. The effect of nanomaterial modification the performance of the prepared loose nanofiltration membranes. The existing problems are analyzed, and the future research direction of using phase inversion method to make loose nanofiltration membrane is prospected.
