摘　　要：通过城市污水处理厂的活性污泥培养出好氧颗粒污泥并处理高浓度猪场废水,对pH值、溶解氧浓度、进水浓度等主要操作条件进行了单因素试验。实验结果表明,颗粒污泥具有良好的生物活性。在进水氨氮浓度较高(>800mg/L)、pH8左右、溶解氧浓度在2.0mg/L的条件下,稳定运行数天后,氨氮和COD的去除率均可达到80%以上。The paper gives some methods such as training aerobic granular sludge by anaerobic-aerobic interactive process, dealing with high concentration of ammonia nitrogen waste by mature aerobic granular sludge. The results show that aerobic granular sludge have good biological activity, the best condition is when Ammonia-Nitrogen concentration is more than 800 mg/L、pH 8,DO concentration is around 2.0 mg/L. Ammonia nitrogen and COD removal rate are above 80%.
