| 摘 要： | 采用盆栽土培试验，研究了工业污泥(化工厂底泥)及城市污水处理厂剩余污泥中重金属存在的形态与含量，以及两种污泥连续施用对潮土重金属含量及酶活性的影响。结果表明，两种污泥中的重金属主要是以非交换态存在，城市污水处理厂剩余污泥中总的重金属含量比工业污泥低，而重金属的有效性比工业污泥高；污泥的施用能增加潮土中脲酶的活性，多酚氧化酶及中性磷酸酶的活性与污泥的施用量有一定相关性，并与土壤中交换态Zn、Cu含量呈一定负相关，土壤多酚氧化酶及过氧化氢酶活性可作为土壤中重金属Zn污染的指示指标；污泥的施用有提高潮土中交换态Cu、Zn及Pb含量的趋势。 |

| Abstract: | Pot culture experiments were conducted to study the effect of industrial and sewage sludge on some enzyme activities and heavy metal concentrations in alluvial soil.The results showed that the heavy metals in both industrial and sewage sludge were mainly non-exchangeable,and those in sewage sludge had a lower concentration but a higher bio-availability than in industrial sludge.The application of sludge could increase the activities of soil urease,polyphenol oxidase and neutral phosphatase,and the polyphenol oxidase and neutral phosphatase activities showed a reverse relationship with the concentrations of soil exchangeable Zn and Cu.Soil polyphenol oxidase and catalase activities could be used to indicate the Zn pollution in soil. |
| Keywords: | Sludge Alluvial soil Soil enzyme activity Heavy metal |
