Abstract
Recently, soil and groundwater contamination has been becoming a serious social problem in illegal dumping sites and improper final disposal sites. In addition, a large-sized illegal dumping sites are newly found one after another. The cost effective methods for remediation of such contaminated sites are necessary. In this study, to apply in-situ bioremediation has been investigated as a pretreatment (detoxification) method in order to reduction treatment cost of removed wastes. As the first step, in this study, we carried out a feasibility study on anaerobic bioremediation.To develop numerical model for anaerobic bioremediation, biodegradation term was introduced to the general convection-dispersion equation. To obtain detradation rate constant, vial tests were conducted, whence dechlorination process of PCE was observed. In addition, column tests provided dispersivity, porosity and retardation factor of PCE. Next, the developed numerical model was applied to hypothetical field to predict effectiveness of anaerobic bioremediation. As a result, distribution and time course of concentration of PCE and its by-products were estimated.
