| 摘 要： | 城市污水处理厂的剩余污泥中含有很多对环境有害的重金属,如何降低这些重金属的析出风险,是污泥土地利用前必须解决的关键问题之一。通过BCR提取法分析了生石灰投加前后污泥中重金属的形态分布。结果表明,生石灰能钝化污泥中的重金属,明显降低污泥中不稳定态重金属的含量。

| Abstract: | There are many heavy metals which are harmful to environment in sewage sludge.How to minimize the mobility of heavy metals is one of the main problems when sewage sludge is used for land.The BCR method is used to analyse morphological distribution of heavy metals in sludge modified by lime or not.Results showed that heavy metals could be stabilized by the addition of lime in sludge. |

| Keywords: | sludge heavy metals lime stabilization |
