| 摘 要： | 依据好氧硝化和缺氧反硝化生物脱氮除碳工艺原理，设计了一体化生物膜法A/O反应器，并将其应用于生活污水处理，取得了理想的处理效果。实验结果表明，水力停留时间HRT＝12 h，COD进水浓度处于150～500 mg/L范围内，COD的去除率均在90%以上，且出水均在40 mg/L以下；当C/N比为8.5以下时，NH3-N去除率高于90%，其出水浓度小于5 mg/L；当C/N比为7.5左右时，具有较高的总氮脱除效果，TN去除率可达到70%。 |
| 关 键 词： | 一体化A/O工艺碳氮比(C/N) 脱氮 |

| Abstract: | Based on the principle of anoxic/oxic (A/O) process,the integrative biofilm A/O reactor was designed and applied to carbon & nitrogen removal for domestic sewage, and the satisfactory results are achieved. The results showed that the removal rate of COD is more than 90% and the effluent COD is less than 40 mg/L when HRT is 12 h and the influent COD concentration is from 150 mg/L to 500 mg/L, and the removal rate of NH3-N is more than 90% and the effluent NH3-N<5 mg/L when carbon to nitrogen (C/N) ratio is less than 8.5. Nitrogen removal is effective, the removal rate of total nitrogen (TN) is more than 70% when C/N ratio is about 7.5. |
