| Résumé: | Transport of Clostridium bifermentans DPH-1 was characterized from laboratory-made column tests using fully saturated Toyoura sand. The conventional transport models were fitted to the column test results to investigate the applicability of prediction and assessment of bacterial transport in actual subsurface or ground water. Laboratory column tests confirmed that the transport characteristics of Clostridium bifermentans DPH-1 in activating tetrachloroethylene dechlorination could be described by mobile-immobile two-region model. The parameters of two-region model i.e. peclet number, retardation factor, fraction rate of mobile water and stanton number were characterized by fitting results. These parameters were also justified by a verification experiment. Two-region model parameters suggested that bacterial injection into the ground at a large concentration is difficult for rehabilitation of widely dispersed contaminated ground water |
