| 摘 要： | 讨论了城市排水污泥中重金属的含量和形态分布特征，分析了堆肥处理对污泥中重金属结合形态转化的影响。根据不同学者的研究结果，提出堆肥处理可降低污泥中Zn、Cu、Pb、Mn等重金属的活性，并指出堆肥处理是降低污泥在土地利用中重金属污染风险的途径。

| Abstract: | This paper discussed the content and morphological distribution of heavy metals in sewage sludge, and analyzed the influence of composting treatment on the morphological transformation of heavy metals in sewage sludge. According to the research results published, it was put forward that the composting treatment can decrease the activity of some heavy metals, such as Zn, Cu, Pb and Mn, in sewage sludge. Consequently, the environmental risk of these heavy metals in land application of sewage sludge can be reduced by composting treatment. |
