摘要：

湿法脱硫工艺是现阶段全世界范围内应用最为广泛的烟气脱硫工艺,在湿法脱硫工艺中,不可避免的要产生一定量的废水。文章结合烟气脱硫废水的水质特征,简要综述了烟气脱硫废水处理工艺中中和、沉淀、混凝以及污泥脱水等各步骤的处理方法和研究进展等,并指出了现阶段我国在烟气脱硫废水处理研究和设计中存在的一些不足。

关键词: 烟气脱硫, 废水处理, 中和, 沉淀, 混凝

Abstract:

Wet lime(stone)-gypsum flue gas desulfurization(FGD) is the most popular process at present worldwide,but wastewater containing a lot of pollutants in the process occurs.The specialty of the wastewater is described.In addition,the treatment method and progress of research on the steps,such as neutralization,precipitation,flocculation and sludge dewatering,etc,are reviewed briefly.At the end,some deficiencies of the process are pointed out.

Key words: flue gas desulfurization, wastewater treatment, neutralization, precipitation, flocculation
