| 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).

| Abstract: | 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 0.1 L/mg and influent ammonia nitrogen loading was lower than 0.08 kg/(m3.d), effluent COD was steadily 30 mg/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 0.08 kg/(m3.d). |
