| 摘 要： | 本文以高渗透压渗流试验装置模拟已被污染的浅层地下水越流通过弱透水层污染深层地下水的过程,研究了有机污染物(菲)通过饱和粘性土弱透水层时的自然衰减特征,以及非生物因子-配位体对于弱透水层中菲迁移转化的影响作用。研究表明,菲的衰减曲线明显分为三阶段:初期吸附截留显著期,中期微生物降解旺盛期,后期微生物降解稳定期;溶液中共存离子HCO 3-、Ca2+与菲形成络合物,SO42-参与菲的生物降解;溶液中主要配位体不同时,菲与阴、阳离子之间相互作用的方式也不同,以络合作用为主。渗透水中菲含量有99%以上被衰减,仅有极少量菲穿透弱透水层。

| Abstract: | High osmosis percolation testing device are designed to simulate the process of contaminated shallow groundwater causes deep groundwater pollution when leakage occurs in the aquitard.The natural attenuation experiment of organic pollutants(phenanthrene) through saturated soil aquitard is specially examined.Experiment of the benthic impact of non-living factor-ligand on the transformation of phenanthrene in the aquitard is also conducted.The results show that the attenuation curve can apparently be divided i... |
