Effects of electron donors on degradation of pentachlorophenol in a methanogenic fluidized bed reactor

摘要

Anaerobic reductive dechlorination of pentachlorophenol (PCP) and other chlorophenols was studied in a laboratory-scale fluidized-bed reactor (FBR). Complete dechlorination of PCP and subsequent phenol removal were achieved at 35 deg. C with a mixed culture from anaerobic sewage sludge, soil and compost, but only after reinocultionwith enrichments fed monochorophenols. The FBR was fed a mixture of glucose, butyric acid and methanol to provide carbon and electrons for the anaerobic culture.
