| 摘 要： | 通过移动床生物膜反应器处理低C/N比生活污水的试验研究,探讨了填料填充率、曝气量和水力停留时间对处理效果的影响,确定出了适合反应器的填充率为53%,最佳曝气量为0.07L/h,最佳水力停留时间为8h。在该实验条件下,COD平均去除率在85%左右,TN去除率最高为62%,平均生物浓度2.63mg/L,生物膜活性强,结果表明反应器对低C/N比生活污水有较好的处理效果。

| Abstract: | Treatment of sewage with low C/N ratio was studied by experiment,and the effects of carriers,aeration quantity and hydraulic retention time(HRT)on treatment efficiency were discussed.Results showed that under the optimal carriers rate of 53%,aeration quantity 0.07L/h and HRT 8h,average removal efficiency of COD and TN could reach more than 85% and 62% respectively.Aeration biological concentration could reach 2.63mg/L,which indicated that the reactor has strong capability for treatment of sewage with low C/... |
