摘要：

A 75 liter immobilized microbe biological reactor with a bed retention time of 20.5 hours was used in a continuous flow mode to remediate contaminated groundwater containing ethylene dichloride (EDC), tetrachloroethylene, and trichloroethylene, with EDC being the predominant contaminant. The reactor was initially seeded with Xanthobacter autotrophicus, a demonstrated halogenated aliphatic substrate utilizer. The reactor was operated for forty‐two days. Material balance determinations for primary volatile aliphatics of concern indicated an average of 90.2% mineralization of EDC, 81.7% of the trichlorethylene (TCE) and 64.0% of the tetrachlorethylene (TeCE). In addition to Xanthobacter autotrophicus, four indigenous bacterial species from the groundwater had successfully acclimated to the reactor bed.
