利用生物活性炭流化床(Biological Activated Carbon Fluidized Bed,BAC-FB)与传统活性污泥法工艺(Conventional Activated Sludge,CAS)对生活污水进行了对比试验研究,对启动时间、处理效果以及沉降性能等进行了探讨.结果表明,同等工况下两工艺相比,BAC-FB启动时间更短,污染物去除率更高,处理效果更加稳定,且可以有效脱除氨氮,不易出现污泥膨胀等问题.BAC-FB出水基本达到国家一级A排放标准,CAS出水仅达国家二级排放标准.BAC-FB技术对于城镇污水处理厂活性污泥法技术升级具有很好的参考价值.

Biological activated carbon fluidized bed(BAC-FB)and conventional activated sludge (CAS)processes were applied to treat domestic sewage.At the start-up time,treatment result and settling performance were studied.The results showed that under the same run control,BAC-FB had shorter start-up time,higher pollutants removal rate and especially ammonia nitrogen removal efficiency.In BAC-FB,reactor state was more stable and no sludge bulking occured.BAC-FB reached standard A of the first grade in(GB 18918-2002),and CAS reached only the second grade.Upgraded work of activated sludge technology in municipal wastewater treatment plant can draw good lessons from this study.
