| 中文摘要 |
| 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. |
| 英文摘要 |
| The influences of variations of temperature and F/M on the TTC-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). |
