Research and application progresses of flue gas desulfurization (FGD) wastewater treatment technologies in coal-fired plants
摘要
Abstract
Water quality and influence factors of flue gas desulfurization(FGD) wastewater and characteristics of treatment technologies were summarized. Future development of FGD wastewater treatment technologies was pointed out. Understanding the characteristics of FGD wastewater is critical to managing its impacts on wastewater system of power plant,the use of coal and limestone,as well as the design and operation of the scrubber. FGD wastewater treatment technologies are classified into four categories,namely,traditional treatment technologies,such as chemical precipitation,advanced treatment technologies,such as biological treatment,zero discharge technologies,such as evaporation treatment in flue duct and other technologies,such as vapor-compression evaporation,respectively. Because of the low discharge standard in China,all technologies except precipitation pond can meet the standard. Up till now,chemical precipitation,as a mature technology,is widely applied in many power plants,which can make FGD wastewater meet the discharge standard,but has low treatment efficiency on Cl−、Hg and Se. By viewing the FGD wastewater treatment situation in China,evaporation treatment in flue duct,as zero discharge method,is considered a potential technology,which has low operating cost but has the possible problems of system corrosion and negative effect on fly ash reuse.关键词
