摘　　要：近年来,污水处理技术不断发展,涌现了很多新方法和手段。利用磁场强化降解污(废)水中的污染物(尤其是高浓度和低浓度的污染物)已成为一项新型的水处理技术。磁技术可以单独使用也可以与其他水处理技术联合使用,其在处理过程中能耗低、易于操作、无二次污染且成本低,是一项极具发展前景的技术。对近几年国内外该方向的研究成果进行了系统阐述,重点介绍了磁场在水处理中的作用原理、磁技术在各类高难度废水处理中的实际应用,并对今后磁技术在水处理中的应用进行了展望。In recent years, wastewater treatment technologies have undergone continuous development, and a large number of new methods and means have emerged. Among them, degrading pollutants in wastewater by using magnetic field has become a new type of wastewater treatment technology （ espe- cially high concentration and low concentration of pollutants）. The magnetic technology can be used a- lone or combined with other technologies. The degradation process has low energy consumption, easy control, no secondary pollution involved, especially, low cost, which makes magnetization a highly prom- ising technology in wastewater treatment. The development process of magnetic technology in wastewater treatment at home and abroad in recent years is described, including the mechanism of magnetic wastewater treatment and the practical application of the magnetic technology in treatment of refractory wastewaters. Future applications of magnetic technology in wastewater treatment are prospected.
