摘　　要：对污泥热处理过程中重金属的行为进行了模拟实验研究,针对处理过程中痕量金属(主要是Cd和Zn)的迁移行为及条件进行讨论.实验表明,该两种物质在过程中其迁移规律呈现与处理体系温度变化直接相关的变化趋势.介绍相互关系、变化趋势等实验结果.As the extension of sewage treatment,the output of municipal sludges is increasing constantly for every countries.And sludge treatment and disposal has been a topic in environmental science and municipal engineering that need to be resolved as soon as possible.This paper made simulation experiment research on the behavior and mechanism of mentals produced in the heat treatment process.It focused on two priority metals： Cd and Zn.The results indicated that migratory disciplinarian of the two substances suited the system temperature directly.
