燃煤电站废水零排放技术方案探究

Inquiry of Zero-discharge Technology Scheme of Wastewater from Coal Fired Power Plant

燃煤电站中废水经处理后复用,复用不了的废水可以采用反渗透浓缩处理,以减少废水量。在气候合适的地区可建设蒸发池,依靠自然蒸发使多余的废水耗散到大气。在不能依靠自然蒸发耗散废水的地区,采用反渗透浓缩加蒸发结晶的技术方案,达到废水零排放。

The waste water in coal fired power plant can be reused after treatment, and the waste water that cannot be reused can be treated by reverse osmosis concentration to reduce the amount of waste water. Evaporation pools can be built in areas with suitable climates to release excess waste water into the atmosphere by relying on natural evaporation.In the areas where natural evaporation can’t be relied on to release waste water, the reverse osmosis concentration plus evaporation crystallization technology scheme is adopted to achieve zero waste water discharge.
