Abstract

The decomposition of high concentration pentachlorophenol (PCP) loaded on granular activated carbon (GAC) was studied by dielectric barrier discharge (DBD) plasma. The effects of discharge voltage, treatment time, gas kinds and flow rate on PCP degradation efficiency were discussed. The results indicated that increasing discharge voltage and treatment time could enhance the degradation efficiency of PCP. The injection of O₂ was more effective than that of air for the degradation of PCP, and the degradation efficiency firstly increased with O₂ flow rate increasing, and then decreased.
