氧化石墨烯复合膜在含油废水处理中的研究进展

氧化石墨烯（GO）膜在水处理方面有较好效果，但纯氧化石墨烯膜稳定性差，抗污性差，通量低，对于油水分离不能达到最优的分离效果。通过引入功能材料进行物理和化学方法改性后，氧化石墨烯修饰的复合膜和氧化石墨烯基复合膜，水通量、防污性能和油水分离效率得到有效提高。本文介绍了国内外具有代表性的氧化石墨烯复合膜在含油废水处理方面的研究，并简要探讨了复合膜去除含油废水的机理，此外对氧化石墨烯复合膜材料的发展前景进行总结和展望。

Research progress of graphene oxide composite membrane in the treatment of oily wastewater

Graphene oxide (GO) membranes have good effects in water treatment, but pure graphene oxide membranes have poor stability, poor fouling resistance, and low flux. They cannot achieve optimal separation effects for oil-water separation. After physical and chemical modification by introducing functional materials, graphene oxide modified composite membranes and graphene oxide-based composite membranes have effectively improved water flux, antifouling performance and oil-water separation efficiency. This paper introduced the research on the treatment of oily wastewater with representative graphene oxide composite membranes at home and abroad, and briefly discusses the mechanism of the composite membrane in the process of oil/water separation. In addition, the development prospects of graphene oxide composite membrane materials are summarized and prospected.
