| 摘 要： | 对污泥生物淋滤过程中各种重金属元素的形态变化情况进行了测定，借助重金属化学形态转化规律，间接判断污泥重金属生物淋滤的转化机制。试验结果显示，Cu、Ni、Cd的生物淋滤是以直接机制为主的，Zn的生物淋滤过程是以间接机制为主的，Cr、Pb的生物淋滤过程属于混合机制，但其混合机理是有差别的。

| Abstract: | The variation of heavy metal speciation during the bioleaching of sludge were carried out. By virtue of heavy metal speciation transformation pattern, the transformation mechanism of heavy metal speciation during the bioleaching could be judged indirectly. The test results show that the bioleaching process of Cu, Ni, Cd are mainly dominated by direct mechanism, the bioleaching process of Zn is mainly dominated by indirect mechanism, and bioleaching process of Cr, Pb are mainly dominated by combined mechanism, while the chemical principle between Cr and Pb are different. |
