摘　　要：颗粒污泥是厌氧反应器稳定运行和高效能的载体。以IC厌氧反应器处理低浓度废水——啤酒废水为例，采用城市污水厂的好氧剩余污泥启动IC反应器，培养过程分为3个阶段：驯化启动期、颗粒污泥出现期和颗粒污泥成熟期。污泥完成颗粒化后，IC反应器OLR负荷稳定在10kg（COD）／（m3·d），COD去除率为75％左右。讨论了颗粒污泥的粒径分布、沉降性能、污泥活性等性质。以期为培养国产的厌氧颗粒污泥积累经验。Granular sludge is the carrier of IC （internal circulation） reactor with steady running and high performance. As a case of brewery wastewater, aerobic residual activated sludge of municipal sewage factory was used to start-up IC anaerobic reactor for treatment of low strength wastewater. The process was divided into three stages： sludge taming, granular sludge forming and maturing. After the sludge has been matured, the organic loading rate （OLR） of IC reactor could steadily keep at 10 kg （COD）/（m3.d）, and the COD removal rate would maintain at about 75%. In respect to granular sludge, its grain-size distribution, settling property, activities, and etc. were discussed so as to accumulate experiences for cultivating anaerobic granular sludge.
