| 摘 要： | 活性污泥培养初期,由于污泥尚未大量形成,细菌消耗的营养和溶解氧少,曝气量大大少于稳定运行期间的曝气量。以缙云污水处理厂为例,对培养初期污泥沉降比(SV30)与溶解氧(DO)以及化学需氧量(COD)去除率之间的关系进行了探讨。

| Abstract: | In initial period of raising activated sludge,less nutrition and dissolved oxygen were needed by bacteria because the sludge was not yet massively formed, the aeration volume was much less than that in the state of steadily operating.Taking Jinyun Sewage Treatment Plant for example,it was researched the relation of sludge settling ratio(SV_(30)) with dissolved oxygen(DO) and removing rate of COD in initial period of raising activated sludge. |

| Keywords: | activated sludge dissolved oxygen sludge settling ratio |
