脱硫废水零排放新型处理工艺

A New Zero Discharge Treatment Process for Desulfurization Wastewater

目前,国内多数燃煤电厂在处理脱硫废水时主要采取的方法为加药絮凝沉淀工艺,但这种工艺由于投运效率较低,因此已经不再适用于燃煤电厂实际需要。文章介绍了脱硫废水深层次处理工艺和零排放处理工艺流程,通过对一系列案例分析,总结出脱硫废水零排放新型处理工艺的应用要点。

At the present stage,most of the domestic coal-f ired power plants in the treatment of desulfurization wastewater,the main method is adding flocculating sedimentation process,but this process is no longer suitable for coal-f ired power plants because of its low operation eff iciency.This article introduces the deep treatment process and zero discharge treatment process of desulfurization wastewater,and summarizes the application points of the new zero discharge treatment process of desulfurization wastewater through a series of case analysis.
