| 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.

| Abstract: | 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(A~2/O) process,the advantages and disadvantages of using TTC-ETS activity to characterize the status of(A~2/O) process were illustrated.The results showed that both temperature and F/M were positively correlated with TTCETS activit... |
