| 摘 要： | 以富含90％±2％纯度聚磷菌(PAOs)的强化生物除磷系统(EBPR)为研究对象,考察了10℃厌氧、10℃好氧、20℃厌氧、20℃好氧4种运行条件下PAOs的衰减特征.结果表明:温度越高对应衰减速率越快,4个系统在1～9 d里衰减速率的平均值分别为:10℃厌氧:0.053/d; 10℃好氧:0.050/d;20℃厌氧:0.072/d;20℃好氧:0.145/d.其中4个系统由于细胞死亡引起的活性衰减速率分别为:10℃厌氧:0.019/d;10℃好氧:0.017/d;20℃厌氧:0.019/d;20℃好氧:0.03/d,占总活性衰减的比例分别为:35.8％、34％、26.4％、20.7％.在9d饥饿衰减期间,污泥中所含PHA与糖原的量总体呈下降趋势.相同温度下,糖原在厌氧衰减过程中降解速率大于好氧；在同样的厌氧、好氧衰减条件下,温度越高糖原降解速率越快.
