摘要
用能进行还原脱氯的微生物富集物接种，在小型试验装置内成功地培养出了具有还原脱氯功能的颗粒污泥。五氯苯酚能被这种颗粒污泥完全脱氯并进一步分解为甲烷和二氧化碳。四氯乙烯和其他氯代乙烯能被颗粒污泥还原脱氯为乙烯。这种脱氯的颗粒污泥可用来处理含有五氯苯酚和氯乙烯类的废水和地下水。
Anaerobic granular sludge was used to treat hazardous chlorinated hydrocarbons,such as pentachlorophenol (PCP), tetrachloroethylene (PCE) and trichloroethylene (TCE). Granular sludge capable of reductive dechlorination of the above chltorinaed compounds was developed in laboratory-scale anaerobic reactors.using microbial cultures enriched with these chlorinated compounds as inocula. The PCP-degrading granular sludeg dechlorinated and then degraded PCP into methane and CO2. The PCE/TCE-dechlorinating granular sludge dechlorinated PCE.TCE and other chlorinated ethylenes into ethylene. These dechlorinating granular sludge could be applied in the treatment of wastewater and groundwater contaminated with chlorophenols and chlorinated ethylene.
