摘要
通过室内土柱实验,研究了垃圾渗滤液的特征污染组分氮、COD在包气带不同介质中的迁移转化特征。实验结果表明,岩性不同的包气带介质是影响氮素、COD迁移转化的重要因素之一,不同介质对氮、COD的净化能力不同;渗滤液对地下水不会造成氮素污染,但会造成有机污染。
Characteristics of nitrogenous and COD in leachate migration and transformation in different types of soils of water logged aeration zone have been studied through laboratory soil - column experiments. The results show that the composition of soil is an important factor which influences migration and transformation of nitrogen and COD. Decontamination capacity of nitrogenous and COD are different with different types of soils. Organism of leachate can result in contaminant to groundwater, but nitrogenous of leachate can not made contaminant to groundwater.
