| 摘 要： | 在厌氧/缺氧(A/A)SBR反应器中考察了污泥龄对反硝化除磷系统效能的影响。结果表明,泥龄对污水中有机物的降解并无明显影响,进水COD基本上都能降解完全;系统脱氮效能受SRT影响不大,只要系统保持SRT大于多数反硝化菌的时代时间,脱氮率基本在90%以上。除磷效果则对SRT变化较为敏感,SRT过低和过高都不利于系统的稳定运行,当SRT为18 d时是维持污泥浓度和除磷效果的最佳结合点。 |
| 关 键 词： | 反硝化除磷 厌氧/缺氧SBR 反硝化除磷菌 泥龄 |

| Abstract: | The effects of biological solids-retention time(SRT) on denitrifying dephosphatation were studied by the anaerobic/ anoxic sequencing batch reactor(A/A SBR).The results showed that the influence of SRT on COD removal was quite limited.The influence of SRT on nitrogen removal was smaller,nitrogen removal ratio always was more than 90% when SRT was longer than generation time;the influence of SRT on phosphorus removal was the biggest,SRT was about 18 d,the reactor could operate stably. |
| Keywords: | denitrifying dephosphatation (A/A)SBR denitrifying phosphorus removing bacteria SRT |
