摘要
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. The results show that the attenuation curve can apparently be divided into three stages. The coexistence ions HCO-3 and Ca2+ in the solution form complex with phenanthrene, SO42- participate in the biodegradation. When the bodies of non-living factor-ligand are different, the zwitter-ion reaction affected with phenanthrene is different, complexation is empirical. Over 99%of phenanthrene is depleted, only a little phenanthrene penetrate the aquitard.
