| 摘 要： | 以砾石为填料采用生物滤池法和以纤维束为填料采用生物接触氧化法，分别预处理沈抚灌渠污水。试验结果表明，在水力停留时间在3．5h，控制气水比分别为5：1和4：1的反应条件下，砾石填料对COD和NH3-N的平均去除率分别为53．9％和53．6％；纤维束软填料对COD和NH3-N的平均去除率分别为55．7％和47．7％。前者对COD和NH3-N的处理效果都达到了预定要求，而后者对NH3-N的处理效果没有达到要求。

| Abstract: | Biofiltration Tank packed with gravels and Biological Contact Oxidation Tank packed with fascieuli were used to per - treat the sewage of Shen - Fu Irrigation Ditch. The results showed that at the conditions of 3.5 h for HRT and 5： 1 and 4：1 for air/water ratio, respectively, the removal efficiency on COD and NH3-N of gravel packing in biofiltration tank achieved about 53.9% and 53.6% respectively, which met the predetermined requirements. Meanwhile that for Faseiculi wadding were 47. 7% and 47.7%, failed to meet the predetermined requirements. |
