摘　　要：从理论上分析了FGD废水与灰水的作用机理,研究了FGD废水对循环冲灰系统中的重金属排放和碳钢腐蚀的影响。结果表明:重金属排放浓度取决于灰水pH值,絮凝吸附作用有利于进一步降低重金属残留量。The reaction mechanism of the FGD wastewater and ash - sluicing water were analyzed theoretically. The simulation experiment of the impacts of FGD wastewater on the heavy metal emission and carbon steel cor- rosion in circulation ash - sluicing water system were studied. The results indicated that the heavy metal emis- sions density was decided by the pH value of ash - sluicing water and the flocculation adsorption was advantageous to further reduction of the heavy metal residual quantity.
