摘　　要：作为21世纪水处理领域的核心技术,膜分离近年来在材料制备和水处理工艺应用等领域取得了显著进展。但是,膜污染始终限制着膜技术的推广应用。通过在膜前采用一定的进水水质预处理措施可有效减缓膜污染,达到稳定系统运行的目的。为了系统认知和理解当前常用的预处理措施,选择混凝、吸附、氧化和预过滤四类预处理方法进行综述,对其膜污染控制效果、机理和应用局限性进行分析比较;并对上述技术领域的创新性发展进行总结,涉及电絮凝的应用、新型吸附剂开发与使用、高级氧化效能提升与风险防控等方面。此外,对某些新兴的水质预处理方法如高压静电场技术、电磁结合技术进行了介绍与应用展望。通过以上分析总结发现,膜前预处理工艺的发展方向是更加简便、集成、低耗和高效,其中技术应用的经济性和简便程度是制约预处理工艺成功应用的关键因素。As the core technology in the 21st century,membrane separation technology in water treatment and wastewater reclamation has made great progress in recent years.Nevertheless,membrane fouling has always been a major obstacle hindering the application of membrane technology.It has been proved that membrane fouling can be effectively reduced by using some pretreatment methods prior to the membrane process.At present,the conventional pretreatment methods mainly include coagulation,adsorption,oxidation,and prefiltration,but they have some disadvantages.Optimization and application of these technologies have been reviewed in the present work.Simultaneously,some emerging processes have been suggested and briefly reviewed.
