摘　　要：本文研究了以褐铁矿和石英砂为填料的缺氧生物滤池的启动,以及在不同水力停留时间下处理模拟生活污水脱氮除磷的性能。结果表明,褐铁矿为填料的滤池启动更容易达到稳定并且处理效果好于石英砂组。水力停留时间(HRT)为12 h,进水化学需氧量(COD)、总氮量(TN)、总磷量(TP)平均浓度分别为101 mg/L、12.2 mg/L、2.06 mg/L,褐铁矿组比石英砂组各去除率分别高2.3%、4%、57.4%;出水COD和TP含量均达到一级A排放标准^([1])。褐铁矿为填料在厌氧/缺氧条件下能够促进氮磷的去除,相比于石英砂更适合作为填料。This paper studies the performance of anoxic biofilters with limonite and quartz sand as fillers, and the treatment of nitrogen and phosphorus in simulated domestic wastewater at different hydraulic residence times. The results show that the filter starting with limonite as filler is more stable and the treatment effect is better than the quartz sand group. The Hydraulic retention time（HRT） was 12 h, and the influent Chemical oxygen demand（COD）, total nitrogen（TN）, and total phosphorus（TP） concentrations were 101 mg/L, 12.2 mg/L, and 2.06 mg/L, respectively. The limonite group had 2.3% and 4% higher removal rates than the quartz sand group, respectively. 57.4%; effluent COD and TP content meet the Class A emission standard. Limonite as a filler can promote nitrogen and phosphorus removal under anaerobic/anoxic conditions and is more suitable as a filler than quartz sand.
