| 摘 要： | 鉴于非生物方法处理城市污泥重金属存在成本高、污染大等缺点，重点探讨了城市污泥中重金属的赋存形态、生物有效性及微生物治理（厌氧、好氧、生物淋滤）、动物处理和植物富集等生物技术去除重金属的机理。提出以生物治理为主，非生物处理为辅的工艺是今后去除城市污泥中重金属的发展方向。

| Abstract: | Due to drawbacks of high cost and heavy pollution in treating heavy metal in urban sludge with non-biological methods, the existence form and biological effectiveness of heavy metal in urban sludge and the heavy metal-removing mechanism of biological technologies such as microbial treatment （anaerobic, aerobic and biological leaching） , animal treatment and plant enrichment were discussed. It was suggested that the technology with biological treatment as major and non-biological treatment as assistance was the development direction of removing heavy metal from urban sludge after now. |
