| 摘 要： | 曝气-过滤一体化装置将生物反应器与过滤机理有机结合，较好地维持了反应器中的高污泥浓度，实现了水力停留时间（HRT）与污泥停留时间的分离。采用连续流间歇曝气工艺对该装置的脱氮除磷效果进行了研究。实验结果表明：在HRT为8h，运行方式为曝气2h、停曝2h的条件下，COD去除率为95．55％，NH3-N未检出，TN为84．90％，TP为93．69％，出水各项指标都达到了GB8978-1996（污水综合排放标准》一级排放标准要求。 |

| Abstract: | The integrated aeration-filtration reactor,which combines a bioreactor with a filter, maintains a higher sludge concentration and realizes the separation between HRT and SRT.Continuous flow-intermittent aeration technology was adopted to study the nitrogen and phosphorus removal effects of this reactor.Under the optimized operating conditions of HRT 8 h,intermittent aeration cycle 2 h- 2 h,the removal rates of COD,NH_3-N,TN and TP are 95.55%,100%,84.90%,and 93.69%, respectively,which can meet the first grad... |
