摘　　要：燃煤电厂脱硫废水中含有较高浓度的Cl-,过量的Cl-会影响脱硫效率、降低石膏品质、导致设备的腐蚀加剧,因此,Cl-的脱除是制约燃煤电厂废水零排放的关键因素。文章介绍了脱硫废水的组成特性,综述了化学沉淀法、吸附法、离子交换法、电解法、氧化法和萃取法等脱硫废水除氯技术的最新进展。在对脱硫废水除氯技术进行分析总结的基础上,提出了脱硫废水除氯技术的产业化应用瓶颈,并对其研究和发展进行了展望。Flue gas desulfurization wastewater(FGDW)of coal-fired power plants contains a relatively high concentration of Cl-.Excess Cl-will affect the flue gas desulfurization efficiency,reduce the quality of gypsum,and cause the corrosion of equipment to increase.Therefore,the removal of Cl-is a key factor restricting the zero-emission of wastewater from coal-fired power plants.This article introduced the composition characteristics of FGDW,and reviewed the recent advances on FGDW dechlorination technologies such as chemical precipitation method,adsorption method,ion exchange method,electrolytic method,oxidation method and extraction method.Based on the analysis and summary of FGDW dechlorination technologies,the industrial application bottleneck of FGDW dechlorination technologies is proposed,and its research and development are prospected.
