摘要
采用Ｈｕｎｇａｔｅ厌氧技术和ＭＰＮ法，研究了升流式厌氧污泥床（ＵＡＳＢ）处理含五氯酚（ＰＣＰ）废水的微生物数量及其分布．结果表明：ＰＣＰ对微生物有一定的毒害作用，经一段时间后各功能群细菌逐渐被驯化，并有效地降解含ＰＣＰ废水．电镜检测表明活性污泥以颗粒状为主，其功能群细菌以杆状菌和丝状菌占优势．
This experiment was conducted to study population and distribution of microorganisms in upflow anaerobic sludge beds(UASB) which were used to treat pentachlorophenol(PCP) wastewater. The results showed that PCP wastewater was poisonous to the anaerobes in short time. Scanning electron microscopy revealed that the most active sludges were granular aggregates and made up predominantly of bacterial rods.
