摘要：

Previous study using batch method showed that an integrated technique using a combination of zero-valent iron and an anaerobic microbial community (FeMB) showed good degradation efficiency for perchloroethylene (PCE). In this study, a permeable reaction barrier (PRB) with FeMB as reactive media was simulated in remediation columns. It was proved that PCE was retardation adsorption and degraded in remediation columns. A mathematical model was developed and used to simulate the transport and transformation of PCE in remediation columns, and was also used to predict the fate of PCE in groundwater in different conditions. Results showed that FeMB PRB might be an environmentally desirable technology and the model could describe successfully the transport and transformation of PCE in remediation columns.
