Abstract

In this study, a two-liquid-phase (TLP) bioreactor was conducted to enhance the biodegradation efficiency and rate of PAH. Phenanthrene was degraded efficiently irrespective of the type and the amount of water-immiscible liquid (WIL). The degradation efficiency of anthracene was much higher in paraffine oil than in silicone oil because the mass transfer of anthracene was different in the two WILs. Pyrene was only transferred from soil to WIL during 5 days. It seemed that the degradation of PAH in the TLP bioreactor was mainly dependent on the mass transfer of PAH.
