| 摘 要： | 采用厌氧-交管好氧缺氧工艺处理城市污水，在厌氧段水力停留时间为初时，COD的去除率达37．5％，污水的BOD／COD由进水的0．492上升到出水的0．557。AAA段在AP＝50％，空气阀开闭周期为60min时，可以去除765％的T－N。本文对AAA段脱氛的效果进行了分析。

| Abstract: | Anaerobic-alternating aerobic-anoxic process (AAA) was employed to treat municipal wastewater. 37. 5 % COD was removed and the BOD/COD of wastewater increased from 0. 492 to 0. 557 when HRT of anaerobic stage was 3h. 76. 5% of T-N was removed during AAA stage when aeration fracti0n (AF) and the air on/off cyc1e period were kept at 50% and 6O min respectively. The factors affected the nitrogen removal of AAA stage were discussed in this paper. |
