| Abstract: | Through the static simulating experiment which was designed to study the static adsorption of petroleum pollutant by gravel,the equilibrium isothermal adsorption equation was determined.A soil column experiment was performed to investigate the dynamic transport of petroleum pollutant in gravel.A model of petroleum pollutant transport in gravel was developed and its parameters were determined.The petroleum pollutant adsorption by gravel conforms to Langmuir isotherm.The adsorption amount is very small and the retardation factor Rd is only 1.06.The ability of petroleum pollutant to transport in gravel is very strong.The model predicted that it only takes 5 days to transport through the gravel of 20m in thickness,and 10 days through that of 100m in thickness. |
