摘　　要：不同填料曝气生物滤池在相同条件下进行挂膜实验.进水流向为上流式,挂膜方式为复合接种挂膜,即先用活性污泥闷曝接种,然后逐步提高进水流速,直到滤料表面形成稳定的生物膜.结果表明,33 d后挂膜成功,在温度为16～24℃,水力停留时间(HRT)为1 h,DO为6 mg/L的情况下,沸石BAF的去除率分别为27%和84%;组合填料BAF去除效果最好,去除率分别为32%和92%.The startup of Biological Aerated Filter （BAF） was compared by zeolite and zeolite -biochemical cotton combined packing. The flow direction was upflow. The filter was filled with activated sludge, and oxygen was supplied by the air compressor, and the primary elarifier effluent and the secondary clarifier effluent of a wastewater treatment plant were fed to the different BAFs, with incremental flow rate of feed water, until the media of BAFs were covered with stable biofilm. The results showed that the start - up of Biological Aerated Filter was successful after 33 days. In the conditions of the temperature was 16 -24 ℃ , HRT was 1 h and DO was 6 mg/L,the removal rate of CODMn and NH4 ＋-N on zeolite BAF was 27% and 84%. The removal of zeolite-Biochemical Cotton filler BAF was best, which was 32% and 92%.
