| 摘 要： | 在传统A2/O工艺基础上,提出了将缺氧池置于厌氧池前面的分点进水倒置A2/O工艺。通过改变α（进入厌氧区的污水分量）与β（进入缺氧区的污水分量）的比例,考察对倒置A2/O工艺脱氮除磷效果的影响。实验结果表明,当α：β为7∶3时,达到最佳的脱氮除磷效率,分别为74.3%和71.2%。

| Abstract: | Based on the conventional A2/O process,the reversed A2/O process for step feed was put forward that an anaerobic tank was put before anoxic tank.The effect of step feed on nitrogen and phosphorus removal by reversed A2/O process was investigated by adjusting the proportion of α（the inflow of sewage into the anaerobic stage） to β（the inflow of sewage into the anoxic stage）.It was found that the optimal efficiency was up to 74.3% and 71.2%,respectively when the ratio of α to β was 7 to 3. |
