摘　　要：石灰石-石膏湿法烟气脱硫(FGD)工艺是目前运用最普遍的火力发电厂脱硫工艺,在脱硫过程中会产生一定量的脱硫废水,由于其水质特殊,必须设置单独的处理设施。文章简要介绍了脱硫废水产生原因,对脱硫废水水质、水量特点进行阐述,结合工程实例介绍脱硫废水处理工艺,从设计和运营方面分析脱硫废水处理工艺存在的问题并给出优化建议与措施。The limestone-gypsum wet flue gas desulfurization(FGD)process is the desulfurization process used widely in power plant at present,which will produce a certain amount of desulfurization wastewater,and because of its special water quality,the treatment facilities must be set up individually.The paper introduces briefly the reasons of desulfurization wastewater production,expounds the characteristics of water quality and water quantity of desulfurization wastewater.In combination with the engineering examples,the paper introduces the desulfurization wastewater treatment process,and analyzes the existing problems of desulfurization wastewater treatment process from the design and operation,as well as puts forward the optimizing suggestions and measures.
