| 摘 要： | 底泥污染是城市河流污染的重要研究内容,也是世界范围的突出环境问题之一。介绍了河流底泥重金属主要以可交换态、碳酸盐结合态、铁锰氧化态、有机结合态、残渣态等形态存在,讨论了pH、氧化还原电位(Eh)、温度、盐度等因素对底泥重金属迁移的影响。综合比较了清淤底泥处理的不同方法,提出控制清淤底泥重金属迁移的首选工艺为黏土物质钝化/稳定化。

| Abstract: | Sediments contamination is not only an important task on studying urban river pollution but also a prominent issue affecting the world environment.This paper presents the main states of heavy metal pollutants in sediments,that is,exchangeable,bound to carbonates,bound to hydrated oxides of iron and manganese,bound to organic matter and others.Factors such as pH,Eh,temperature and salinity that contribute to the transport of heavy metal pollutants in sediments are also discussed.The passivation and stabilizi... |
