摘　　要：电容去离子(CDI)技术因具有高效、节能、环保、经济等优异性能,自20世纪60年代发明至今,一直得到研究者的广泛关注。在查阅资料的基础上,从理论研究、工程应用、材料研究3个方面介绍了CDI技术的发展历程,并分析了其理论原理、电化学反应过程、能耗与经济性,并从运行条件和电极优化2个方面对效率的优化提升进行了深入探讨,介绍了CDI技术装置国内外产业化应用情况,提出了CDI技术不仅在脱盐及污水处理领域具有较大发展空间,在环境废物资源化回收方面同样具有广阔的应用前景。Capacitive deionization（CDI） technology has attracted extensive attention since invented in 1960 s due to its outstanding performance, such as high efficiency, low power input, environmental friendly and low cost. On the basis of data access, the development history of CDI techonlogy was introduced from three aspects,including theoretical, engineering and material. Meanwhile, the theoretical basis, electrochemical reaction process,energy consumption and economy property were summaried. Afterwards, two common methods to improve the desalination performance, the optimization of operation condition and electrode material, were expounded. Then,The industrialization of CDI technology was introduced. The author stated that CDI technology not only has a bright future in the field of desalination and wastewater treatment, but also in the area of resource recovery.
