摘　　要：研究了温度和F/M的变化对A2/O系统TTC-ETS活性的影响,分析了TTC-ETS活性与COD降解的相关关系;通过低C/N冲击下TTC-ETS活性和理化指标的比较,讨论了以TTC-ETS活性表征系统运行状况的优劣.结果表明,一定范围内,温度与F/M均与TTC-ETS活性成正相关,TTC-ETS活性(TF/TSS.t)变化范围约13.2~48.3 mg/(g.h),最大值约为60 mg/(g.h);TTC-ETS活性与COD去除率相关性显著,并且TTC-ETS活性可预警系统的异常状态,当TTC-ETS活性为41.0 mg/(g.h)时,COD去除效率最高.The influences of variations of temperature and F/M on the TYC-ETS activity have been experimentally studied. The correlation between TTC-ETS activity and COD degradation was also analyzed. Comparing TTC-ETS activities with physical and chemical indexes when high C/N ratio impacted A2/O process, the advantages and disadvantages of using TTC-ETS activity to characterize the status of A2/O process were illustrated. The results showed that both temperature and F/M were positively correlated with TTC-ETS activity. TTC-ETS activity was in the range of 13.2-48.3 mg/（g·h） and the maximum value was 60 mg/（g·h） which had a significant relationship with COD removal rate. In this system, abnormal state was pre-warned by TTC-ETS activity. The highest removal rate of COD appeared when TTC-ETS activity was 41.0 mg/（g·h）.
