摘要

流动电极电容去离子（FCDI）技术是近几年基于电容去离子（CDI）技术发展起来的新型脱盐技术。采用液体型流动电极，并外接直流电源，可吸附离子，实现水的净化。简要介绍了FCDI的发展及原理，详细阐述了运行模式、流动电极、电压、初始溶液浓度、pH值、离子种类、流速因素对FCDI脱盐性能的影响，提出FCDI技术具有低能耗、高效率的优点，解决了CDI技术不能连续脱盐、脱盐容量低等缺点，将来势必会成为海水淡化的一种主流技术。

Abstract：

Flow-electrode capacitive deionization(FCDI) technology is a new type of desalination technology developed based on capacitive deionization (CDI) technology in recent years. Through adopting liquid type flow-electrode and external DC power supply, the ions can be absorbed to realize water purification. The development and principle of FCDI were briefly introduced, and the effects of operating mode, flow electrode, voltage, initial solution concentration, pH value, ion type, and flow rate factors on FCDI desalination performance were elaborated in detail. FCDI technology has the advantages of low energy consumption and high efficiency, which solves the disadvantages of CDI technology such as continuous desalination and low desalination capacity. It will inevitably become a mainstream technology for seawater desalination in the future.

Key words： FCDI desalination rate adsorption capacity water treatment
