Produced water is the largest wastewater generated in oil and gas industry and its handling has become a significant issue of environmental concern. Due to its massive production, it has caught the attention of the researchers to find the most effective solution. As the front-runner of advanced fiber materials, electrospun nanofiber membrane (NFM) has high potential for oily wastewater treatment since it offers promising properties such as huge surface area, high porosity, tuneable wettability, great permeability and small basis weight. However, fouling issue and low mechanical strength of NFM will mitigate membrane performance over time. Therefore, membrane surface modification methods are applied to reduce fouling and promote crosslinking of nanofibers to improve the mechanical strength of membrane. In this review, it highlights and summarizes the research and development starting from the design concepts and the synthesis of nanofiber membranes and how membrane modification is important for effective oil/water separation.

采出水是石油和天然气工业中产生的最大废水，其处理已成为环境关注的重要问题。由于其大量生产，它已引起研究人员的关注，以找到最有效的解决方案。作为先进纤维材料的领先者，电纺纳米纤维膜（NFM）具有处理含油废水的巨大潜力，因为它具有广阔的表面积，高孔隙率，可调节的润湿性，良好的渗透性和较小的单位面积重量等广阔前景。但是，结垢问题和NFM的低机械强度会随着时间的流逝降低膜的性能。因此，应用膜表面改性方法来减少结垢并促进纳米纤维的交联以提高膜的机械强度。在这篇评论中
