摘　　要：针对酒精废水中难生物降解的有机物,从氧化塘污泥中筛选分离出高适应能力和降解能力的高效优势菌群,将其投加到升流式厌氧污泥床反应器中进行中试。运行结果表明:利用高效优势菌群培养高活性的颗粒污泥,可大大强化UASB反应器的废水处理性能,35d即可完成系统的启动;反应器容积负荷从2.0kg/(m3.d)提高到39.0kg/(m3.d),COD去除率保持在90%左右,最高达到96%。Aiming at the resistant-biodegradable organics in alcohol wastewater, the dominant bacteria with good adaptability and high degrading capability were isolated from sludge of oxidation pond and put into the upflow anaerobic sludge bed（ UASB ）reactor for pilot test. The results indicate that the high activity granular sludge cultured with dominant bacteria can greatly enhance the wastewater treatment capability of UASB reactor. The startup of the system was achieved in 35 d. When COD volume load increased from 2.0 kg/（ m^3 · d） to 39.0 kg/（ m^3 · d） ,the removal rate of COD was kept at about 90%, while the maximum value was 96%.
