Research on the Migration of Naphthalene in the Typical Aquifer Medium in a Petroleum Contaminated Field

Through the column simulation experiments, this paper researched on the naphthalene migration in the typical aquifer media-gravel sand and coarse sand in a petroleum contaminated field. The research also quantified the retardation of the two medium to the important petroleum component-naphthalene, by giving the retardation parameter after the chlorine breakthrough experiment. The results showed that the migration of naphthalene in the medium is not only influenced by the convection and the dispersion, but also the adsorption and the biodegradation, which is much stronger in the coarse sand than it is in the gravel sand.
