摘要:

为实现火力发电厂废水零排放的目标,对脱硫废水预处理工艺、脱硫废水浓缩处理工艺以及末端浓盐水的蒸发结晶处理工艺进行技术对比,选取适合电厂实际情况的技术方案。处理后的冷凝水可以作为工业水,使电厂水处理系统实现闭式循环,没有任何外排水,真正实现废水零排放。

Abstract:

To realize thermal power plant waste water zero emission, technology of desulfurization waste water preprocess, desulfurization waste water concentrated treatment and tail strong brine evaporative crystallization was compared. The propitiated proposal was selected. Postprocessed condensate water could be used as industrial water, and realized power plant water treatment system closetype circulating. There is not any water discharged. Waste water zero emission was realized.
