Abstract

Abstract:

Wet flue gas desulfurization(WFGD) process is the most widely used desulfurization process at the present stage in the world. A certain amount of wastewater would inevitably be brought about from this process. The causes and harms brought about in the desulfurization wastewater are introduced. The research status and shortage of desulfurization wastewater treatment process are expounded. Combining with the characteristics of water quality,the treatment method of all kinds of pollutants in desulfurization wastewater are summarized. On this basis,the methods for treating chloride,sulfate,COD and selenium in the desulfurization wastewater are forecast.

Key words: wet flue gas desulfurization, coal combustion, desulfurization wastewater, selenium pollution

摘要：

湿法烟气脱硫工艺是现阶段世界范围内应用最广泛的脱硫工艺,该工艺不可避免地会产生一定量废水。介绍了脱硫废水的产生原因及危害,对脱硫废水处理工艺的研究现状和不足进行了阐述,并结合水质特点综述了脱硫废水中各污染物的处理方法。在此基础上对脱硫废水中氯离子、硫酸根、COD及硒的处理方法提出了展望。
