摘　　要：使用透水混凝土生态膜作填料,利用渠式生物膜反应器,对生活污水进行处理。结合实验数据,对新型反应器中填料上生物膜的活性进行了分析。实验表明,其活性(以耗氧速率SOUR表示)在3.23～6.25 mgO2/g.h之间,其生物膜量在3.16～10.72mg/cm2之间,生物膜量的变化趋势是沿程下降,而SOUR却是上升的。Domestic sewage was treated by a canal-type biofilm reactor with concrete eco-film as filling, and the activity of the biofilm on the filling in the reactor was analysed. It was showed that its activity （being expressed with oxygen consumption rate SOUR） was within 3.23 ～6.25mgO2/g .h; its biofilm biomass was within 3.16～ 10.72mg/cm^2 and was descendent along the length of canal-type reactor while SOUR was ascending.
