摘　　要：考察了折流曝气生物滤池(BBAF)内的生物膜和微生物种群的分布特征。结果表明:BBAF各单池的比质生物量和比面生物量均随运行时间的增加而增加;沿流程方向各单池的比面生物量逐级递减,而比质生物量呈N字型变化;各单池的生物膜活性沿流程方向也呈N字型变化;由于各单池之间存在浓度梯度,可形成各自的微生物优势种属,有利于BBAF达到最佳运行效果。The spatial-temporal changes of biofilm and microorganism population in baffled biological aerated filter （BBAF） were investigated. The results indicate that biomass per unit area and biomass per unit mass of each filter in BBAF are increased with increasing run time. The biomass per unit area of each filter is decreased gradually along water flow, while the biomass per unit mass of each filter shows N shape change. The biofilm activity of each filter also shows N shape change. Because of concentration gradient, dominant microorganism population can be formed along the water flow in different filters, which improves treatment effect of BBAF.
