电厂脱硫废水零排放处理工程实例

Case study on the zero discharge treatment of desulfurization wastewater from a power plant

以山东某电厂脱硫废水零排放处理工程为例,介绍了脱硫废水零排放处理流程、主要工艺以及项目调试运行情况。从运行效果来看,采用混凝沉淀+多介质过滤+DTRO+蒸发结晶可完全实现脱硫废水的零排放要求,膜浓缩产水及蒸发器凝液符合回用要求。

Taking the zero discharge of desulfurization wastewater treatment project of a power plant in Shandong as an example,the processing flow,main process,the project debugging and site operation of the zero discharge of desulfurization wastewater are introduced. According to the operation effect,the zero discharge requirements of desulfurization wastewater can be realized completely by means of coagulation sedimentation＋multi-medium filtration＋DTRO＋evaporation crystallization. The water produced from membrane concentration and evaporator condensate meet the reuse requirements.
