Degradation of Trichloroethylene and Trans-1,2-Dichloroethylene by a Methanotrophic Consortia in a Trickle-Type Bioreactor.

摘要

A trickle-bed bioreactor containing a consortium of microorganisms utilizing methane as the primary carbon source was used to treat a synthetic groundwater containing trichloroethylene (TCE) and trans-1, 2-dichloroethylene (DCE). With influent concentrations of TCE and DCE of 1 mg/L each and an average residence time of about 50 min, >50% of the TCE and >90% of the DCE was degraded. The reactor exhibited first-order kinetics with respect to TCE degradation. 5 refs., 1 tab. (ERA citation 14:003586)
