摘要
对目前国内外燃煤锅炉烟气脱硫废水处理的多种方法,如混凝-沉淀法、流化床法、人工湿地法、单质铁法、微滤膜法、生化法和改良混凝-沉淀法等进行了分析评述。研究发现,开发技术集成度大、流程短、药剂种类和用量少、一次性投资以及运营费用低的工艺技术是未来发展的方向,而改良混凝-沉淀法脱硫废水处理技术符合要求,是一项值得加强应用研究和推广的新技术。
Analysis of the flue gas desulfurization （ FGD） wastewater treatment technologies, including floccula-tion-precipitation process,fluid bed process, constructed wetlands process,hybrid zero-valentiron process, microfiltration membrane process, biochemistry process and improved flocculation -precipitation process, in coal-fired power plant were made.The methods, whichis of higher develop integration degree, shorter flow, less types and dosage of regents, lower cost in investment and operation, are worth to be anticipated.The im-proved flocculation-precipitation process, namely the one-step FGD wastewater treatment method that needs to be developed in application research, is a new way that matches these requirements.
