| 摘 要： | 在0.15MWt循环流化床燃烧试验台上进行了城市垃圾与煤混烧试验,对焚烧后的灰渣中重金属的特性进行了研究。研究结果显示,重金属在焚烧产物中通常以不同的化合物形态存在,改变垃圾与煤混烧时的燃烧工况条件,可以改变重金属的化合物形态,从而改变重金属在灰渣中的分布;灰渣中重金属的浸出毒性低于危险废物浸出毒性鉴别标准中的限定值。

| Abstract: | Experiments of co-firing of MSW and coal was made in a 0.15 MWt circulating fluidized bed combustor and the characteristics of heavy metals in the ash samples were analyzed. The results show that the heavy metals exist in ash in different compound forms. The compound forms and the distribution of the heavy metals in ash are changed with the co-firing conditions. The extraction toxicity of the heavy metals in ash is less than the regulation values of the identification standard for hazardous wastes. |
