| 摘 要： | 由于垃圾焚烧飞灰富集的重金属浓度较高,为减少对环境造成二次污染,应进行妥善处理.本文研究了垃圾焚烧飞灰在600～1100℃之间重金属Pb、Cd、Cu、Zn的蒸发特性,并研究了添加剂CaCl2对重金属蒸发特性的影响.结果表明,在没有氯剂加入的情况下,重金属Cd、Pb的蒸发率较高,均在90%以上,Cu在80%左右,而Zn的蒸发最少,小于40%;当有氯剂加入时对所研究的重金属的蒸发都有不同程度地增加,其中以Zn的蒸发量增加最多.

| Abstract: | In order to reduce the secondary pollution caused by municipal solid waste incineration (MSWI) fly ash, it must be treated soundly before final disposal, because the content of heavy metals in MSWI fly is high. In this paper, the evaporation of heavy metals (Pb, Cd, Cu, Zn) were studied between 600 degrees C-1100 degrees C, meanwhile the influence of CaCl2 on heavy metals' evaporation was studied. The result shown that without chlorination agent, the evaporation for Pb and Cd were as high as above 90%, about 80% for Cu, less than 40% for Zn. It was also found the evaporation of the heavy metals was enhanced when chlorination agent was added, and for Zn the evaporation increase was the most. |
