摘要: The contamination of groundwater by organic compounds is becoming more common and severe. A diesel tracer, a light non-aqueous phase liquid (LNAPL), was selected to carry out experiments contaminant migration in fractured porous media. At the same time, trials remediation methods were conducted using distilled water. experimental results showed that dominant flow obvious media than owing effect fractures on migration. mechanism revealed movement oil-driven air water-driven oil. dispersion parameters these calibrated through calculated areas measured areas, numerical method. predicted indicate greater injection rate, shorter time penetrate However, relative LNAPL experiments, oil processes slower longer at rate.
