| 摘 要： | 受垃圾渗滤液影响,垃圾场周边土壤有机物含量增加。试验结果显示,随着土壤有机物含量的增加,土壤中有效态铁锰含量增大。垃圾场周边土壤中渗滤液有机物和金属铁锰共存时,大量的有机物质能活化土壤中的铁锰,增加其有效性,增强其在土壤中的迁移能力。从而造成垃圾场地下水较严重的铁锰污染。

| Abstract: | With the influence of waste leachate seeping, the concentration of organic substances in landfill soil was higher than that in unpolluted soil. This study indicated that the organic substances of waste leachate could active iron and manganese, enhanced the concentration of available form of iron and manganese, and amplified them the removal ability in soil. It was therefore the reason that caused the iron and manganese pollution in groundwater of landfill site. |
