基于近几年国内外研究进展，总结了现有的废水脱氯技术及其应用，对比分析了各种技术的优缺点。以电解法、烟道蒸发法和膜分离技术为例，介绍了其在脱硫废水零排放中的应用。统计了各种废水脱氯方法在脱硫废水中应用的相关文献情况，综合考虑实际运行情况及处理成本等因素后发现，烟道蒸发法和膜分离技术可能是最适合我国脱硫废水脱氯从而实现零排放的经济可行的方法。

Based on global research progress in recent years, available chloride ion-removal technologies for wastewater and their applications are summarized, and their advantages and disadvantages are compared and analyzed.Taking electrolysis, flue evaporation and membrane separation methods as examples, their applications in desulfurization wastewater are introduced.In addition, the relevant literature on the application of various methods in treating with desulfurization wastewater is also counted.Taking account into the operation and treatment costs, it can be concluded that flue evaporation and membrane separation technologies might be the superior economic and feasible methods for chloride ion-removal of desulfurization wastewater in China.
