摘　　要：采用SBR反应器培育形成了直径在1.2-1.4 mm之间的好氧颗粒污泥,此时废水的COD降解率在90%以上;出水中硝酸盐氮值保持在5 mg左右,硝化与反硝化达到了平衡.随后利用该颗粒污泥对化学制药废水进行处理,结果显示:氨氮和COD的降解率都很低;颗粒污泥发生了解体,出水变得浑浊.Aerobic granular sludge is cultivated in the SBR reactor successfully. The average diameter is between 1.2- 1.4mm. The characteristics and application of aerobic granular sludge are investigated. Followng results have been obtained：Nitrate nitrogen value in the effluent is sustained in around 5mg and this shows the nitrification and denitrification reaches the equilibrium,at the same time, the removal rates of COD is more than 90%. Then the aerobic granular sludge is used to treat chemical plarmaceutical wastewater. The results show that the rate of degradation of ammonia nitrogen and COD are all quite low. Aerobic granular sludge is disintegrated and the effluent is turbid.
