中文摘要：

为解决包头市某生活污水处理厂出水氨氮含量偏高的问题,采用以新型聚乙烯SDC为生物填料的上流式Biostyr曝气生物滤池（BAF）处理该生活污水,进行了接种挂膜实验,考察了BAF对该生活污水COD、TN及NH4^＋-N的去除效果以及温度和溶解氧含量对NH4^＋-N去除效果的影响。结果表明,在水温为17.4～22.2℃、进水体积流量为12L/h、进气体积流量为36L/h、气水体积比为3：1的条件下,BAF系统在17d内生物膜成熟;系统稳定运行后,COD、TN、NH4^＋-N的平均去除率分别为82.54%、70.36%、86.82%,出水水质满足GB 18918-2002一级A标准,为BAF在该厂的实际应用提供了参考。

英文摘要：

To solve the problem of high concentration of the effluent NH4^＋-N in a sewage treatment plant of Baotou, Inner Mongolia, an up-flow Biostyr biological aerated filter（BAF） with a new type of polyethylene SDC filtering material was used to treat domestic sewage. To understand the removal efficiencies of COD, TN and NH4^＋-N, the inoculate biofilm formation methods was used. The effect of water temperature and DO content on NH4^＋-N removal was studied. The results showed that when water temperature varied from 17.4～22.2 ℃, at the volume quantity of 12 L/h, air/water volume ratio of 3：1, the biofilm formation of BAF reactor was achieved after 17 d. After the biofilm formation, the average removal rates of COD, TN and NH4^＋-N were82.54%, 70.36% and 86.82% respectively, the effluent quality was satisfactory with the first level A criteria specified in the GB 18918-2002, and provided useful reference for practical application of BAF.
