| 中文摘要 |
| 试验表明,生物接触A/O工艺对官厅水库入库水中COD、氨氮等污染物有明显的去除效果,可以有效地改善官厅水库入库水的水质.在单位供气量(空气/氨氮)≥0.1L/mg,进水氨氮负荷≤0.08kg/(m3·d)的条件下,处理后出水COD稳定在30mg/L左右,氨氮去除率＞60%,TN的去除率为1.0%～31.3%.进水氨氮负荷是主要的控制参数,应控制在≤0.08kg/(m3·d). |

| The results of the experiments showed that biological contact A/O process had evident removal effect of contaminations such as COD、ammonia nitrogen in water entering into Guanting Reservior and could successfully resume the quality. Under the conditions that air supply flux(gas/ ammonia nitrogen)was more than 0.1L/mg and influent ammonia nitrogen loading was lower than 0.08kg/(m3·d), effluent COD was steadily 30mg/L around, ammonia nitrogen removal rate was higher than 60%, and TN removal rate was 1.0%～31.3%.The main control parameter was influent ammonia nitrogen loading, which was proposed to be lower than 0.08kg/(m3·d). |
