| 摘 要： | 为了更好地实现并维持稳定的部分亚硝化效果,以低氨氮人工配水为研究对象,采用连续流完全混合式活性污泥法(CSTR),在常温条件下对部分亚硝化工艺的影响因子和准佳工况进行了研究。结果表明,HRT=(3.0±0.2)h,DO为0.40～0.50 mg/L,回流比R=20%～30%时,平均氨氧化率为53%,且工艺出水NO2--N/NH4+-N平均为1.11∶1,适宜作为系统长期稳定运行的工况。若持续缩短HRT会导致反应器内污泥浓度降低,部分亚硝化效果受到影响。反应器在上述工况运行时,DO=0.50 mg/L是亚硝化率下降的临界浓度;系统进出水pH差值可良好表征出水亚硝酸盐氮与氨氮浓度的比例。 |
