摘　　要：对Z市B水厂和S水厂的活性炭滤池运行状况开展了长期运行监测。结果显示,中原地区黄河原水的活性炭吸附周期为3个月,BAC对氨氮和COD_(Mn)的去除率与季节性温度变化呈正相关;重力流活性炭滤池通过生物降解作用去除氨氮和COD_(Mn)的能力优于上向流活性炭滤池,更适用于有机物浓度较低的原水深度处理。另外,还发现活性炭的生物量、微生物数量和微型动物种类可以作为活性炭生物降解去除氨氮和COD_(Mn)能力的评价指标。Performances of the biological activated carbon （BAC） filters in B and S water treatment plants in Z City were monitored for a long time. The results showed that, for the Yellow River raw water in the central plains region, the activated carbon adsorption cycle was 3 months, and the removal rate of ammonia nitrogen and CODMn in BAC were positively correlated to the seasonal changes in temperature. The capability of removing ammonia nitrogen and CODMn of the gravity flow activated carbon filter was superior to that of the upflow filter, and was more suitable for the treatment of the raw water with low concentration of organic matters. In addition, it was found that the BAC biomass, the microbial poulation, and microfauna species could serve as indicators to evaluate the capacity of ammonia nitrogen and CODM, removal.
