| 摘 要： | 就曝气时间段DO的变化对处理效果的影响进行了实验，研究结果发现DO在3．0mg／L时COD去除率达90．7％；CASS工艺对NH3-N的去除效果随DO浓度降低而变坏；对TN的去除最佳点也是在130浓度为3．0mg／L时，去除率为73．3％；对TP的去除率在DO浓度为1．0～3．0时均能达到94％；CASS出水均能达标排放。

| Abstract: | This article is studied on the aeration time period DO deal with the effect of the changes.We fond the DO at 3.0 mg/L,the COD removal efficiencies is 90.7%,the NH3-N removal effect reduce with the DO concentration,to TN removal,the best point in the DO concentration of 3.0 mg/L,the removal rate of 73.3%,to the removal of TP,the DO concentration of 1.0 to 3.0 hours can reach the removal rate of 94%.The CASS water leakage can attain a designated standard the emissions. |
