| 摘 要： | 用没ＰＨ值溶液对炉前原煤、灰化灰、底灰、飞灰进行了对比淋滤试验。重点考察了Ａｓ、Ｚｎ、ＰＢ、Ｎｉ、Ｓｒ等５种元素的淋出行为。发现溶液的ＰＨ、淋滤时间，特别是元素的性质及其赋存状态对元素的淋滤难易程度有重要影响，所分析的５种元素中，Ｓｒ以强淋滤为主，Ｐｂ和Ａｓ以强淋滤和中等淋滤为主，Ｎｉ以中等淋滤为主，而Ｚｎ则为难淋滤元素。

| Abstract: | he comparative leaching experiments of coal(C),ashing ash(AA),fly ash(FA) and bottom ash(BA) have been carried out under different PH conditions.The leaching behaviour of As,Zn,Pb,Ni and Sr have been investigated in detail.The results have shown that the pH values of solution,leaching time,and particularly,the properties and species of the elements existed have heavily influenced on the leaching behaviour of elements.Among the 5 elements analysed,the leaching ability of Sr is strong,Pb and As strong to middle,Ni middle and Zn weak. |
