| 摘 要： | 以四川某城市为例,对医疗垃圾焚烧飞灰进行了重金属的浸出特性实验,探讨了不同液固比、初始pH值及浸取剂对飞灰中重金属Cu、Zn、Pb、Cd、Ni的浸出影响.结果表明,重金属的浸出率随着液固比的增加而增加;重金属在酸性条件下较易浸出,而在碱性条件下渗滤较少;不同的浸取剂对重金属的浸出也有一定影响.

| Abstract: | The leaching experiments are performed to conduct discussions on the relationships among liquid-to-solid ratio,initial pH value and the leaching effects of leaching solvents on heavy metals(Cu,Zn,Pb,Cd,Ni) in fly ash.It is concluded that the leaching ratio of heavy metals increases with the L/S,heavy metals are easy to leach under acid condition,while hardly leach under alkaline condition,and leaching characteristics are also influenced by the different leaching solvents. |

| Keywords: | medical waste fly ash liquid- to- solid ratio content of heavy metal |
