摘要
石灰石—石膏湿法脱硫工艺是目前国内应用最广泛的脱硫工艺,随着国家环保标准的日益严格,减少脱硫废水排放、提高水资源的回收利用率,逐渐成为燃煤电厂下一步环保工作的重点。文中介绍了燃煤电厂处理脱硫废水的3种典型工艺,通过案例分析,论述了废水零排放的可行性,并提出了具体建议和措施。
The limestone-gypsum wet flue gas desulfurization technology has been the main desulturization technology at present. With the environmental standards becoming more and more strict, reducing the discharge of desulfurization wastewater and enhancing the reclamation of water gradually become the focus for coal-fired power plants. In this paper, three typical flue gas desulfurization wastewater treatment technologies are, discussed based on variation analysis. Zero discharge feasible of desulfurization is proven. In ad- dition, specific measures are proposed.
