摘要
随着工业化发展,高盐有机废水的排放对环境造成严重影响。传统处理方法能耗高且效率低,而纳滤技术凭借其对多价离子和有机物的选择性截留,展现了良好的处理效果。综述了纳滤技术在高盐有机废水处理中的应用进展,分析了膜的分离机制、材料改性、工程应用及影响因素。并探讨了纳滤与其他膜技术耦合应用的潜力以及未来发展方向和面临的挑战,为高盐有机废水的高效处理提供参考。
With industrial development,the discharge of high-salinity organic wastewater has caused serious environmental impacts.Traditional treatment methods are energy-intensive and inefficient,while nanofiltration(NF)technology,due to its selective rejection of multivalent ions and organic compounds,has shown promising treatment effects.This paper reviews the application progress of NF technology in the treatment of high-salinity organic wastewater,analyzing the membrane separation mechanisms,material modifications,engineering applications,and influencing factors.It also discusses the potential of coupling NF with other membrane technologies and explores future development directions and challenges,providing a reference for the efficient treatment of high-salinity organic wastewater.
