An important way to promote the environmental industry's goal of carbon reduction is to promote the recycling of resources. Membrane separation technology has unique advantages in resource recovery and advanced treatment of industrial wastewater. However, the great promise of traditional organic membrane is hampered by challenges associated with organic solvent tolerance, lack of oxidation resistance, and serious membrane fouling control. Moreover, the high concentrations of organic matter and inorganic salts in the membrane filtration concentrate also hinder the wider application of the membrane separation technology. The emerging cost-effective graphene oxide (GO)-based membrane with excellent resistance to organic solvents and oxidants, more hydrophilicity, lower membrane fouling, better separation performance has been expected to contribute more in industrial wastewater treatment. Herein, we provide comprehensive insights into the preparation and characteristic of GO membranes, as well as current research status and problems related to its future application in industrial wastewater treatment. Finally, concluding remarks and future perspectives have been deduced and recommended for the GO membrane separation technology application for industrial wastewater treatment, which leads to realizing sustainable wastewater recycling and a nearly "zero discharge" water treatment process.
促进环境产业碳减排目标的一个重要途径是促进资源回收。膜分离技术在资源回收和工业废水的高级处理方面具有独特的优势。然而，传统有机膜的巨大前景受到与有机溶剂耐受性、缺乏抗氧化性和严重的膜污染控制相关的挑战的阻碍。此外，膜过滤浓缩物中高浓度的有机物和无机盐也阻碍了膜分离技术的更广泛应用。新兴的具有成本效益的氧化石墨烯（GO）基膜具有优异的有机溶剂和氧化剂耐受性、更高的亲水性、更低的膜污染、更好的分离性能，有望在工业废水处理中做出更大的贡献。在此，我们全面介绍了 GO 膜的制备和特性，以及其在工业废水处理中的当前研究现状和未来应用中存在的问题。最后，为了实现可持续的废水循环利用和近乎“零排放”的水处理过程，我们对 GO 膜分离技术在工业废水处理中的应用进行了总结和展望。
