采用SBR反应器培养好氧颗粒污泥,考察了低曝气量下好氧颗粒污泥的性能. 研究表明,低曝气量下,好氧颗粒污泥具有较高处理效能,其对校园污水中COD、氨氮和磷的去除率最高可分别达到93.8%、87.7%、87.8%.降低曝气量有利于磷的去除,对COD去除的影响不大,对氨氮去除的影响较大.当曝气量为0.2 m3/h时,氨氮去除率最高. 降低曝气量,DO浓度的变化不显著. 好氧颗粒污泥能在低曝气量下稳定运行,在保证污染物去除率的前提下可降低能耗,节约能源.

SBR has been used for the cultivation of aerobic granular sludge ,and the performances of aerobic granu-lar sludge at low aeration rate are investigated. The research shows that ,aerobic granular sludge at low aeration rate has higher treatment efficiency. Its removing rates of COD ,ammonia-nitrogen and phosphorus from the sewage in the campus are 93.8%,87.7%,and 87.8%,respectively. Reducing aeration rate is good for the removal of phospho-rus,but the influence on the removal of COD is not much,and the influence on the removal of ammonia-nitrogen is greater. When the aeration rate is 0.2 m3/h,the ammonia-nitrogen removing rate is the highest. Reducing the aeration rate,the change in DO concentration is not obvious. Aerobic granular sludge can work stably at low aeration rates. The energy consumption can be lowered,and energy sources can be saved,under the precondition for ensuring the pollutant removing rates.
