摘　　要：将水泥、碎石、粉煤灰及活性材料CRLT-1等制作的透水混凝土生态膜在渠式反应器中进行挂膜实验,通过实验对2种挂膜方法进行了比较,对2种挂膜方法下填料上的生物量和生物活性及反应器对COD和NH3-N等指标的去除情况进行了测定和分析。结果表明,逐渐增加进水流量的循环挂膜法可以加快反应器启动,10d后COD的去除率稳定在69%左右,启动时间少于直接采用设计流量进水的循环挂膜法,2种情况下生物活性在4.19～4.85mgO2/g·h之间。Porous concrete eco-films made from cement,crushed stones,coal ash and activated material CRLT-1 was used to carry out start-up experiment in cannel reactor.Two start-up methods were compared,and biomass attached to porous concrete eco-films and its biological performance during the start-up were analysed.Results showed that the start-up with incremental flow rate can accelerate the microorganis accumulation in the cannel reactor system and shorten the start-up time comparing with nominal process flow rate,with removal efficiency of COD up to 69% in 10 days and biological performance in 4.19～4.85mgO2/g·h.
