摘要
采用一套由SBR反应器和一个内部填充多孔蜂窝陶瓷填料的生物滤池(BAF)构成的组合系统,研究了不同碳氮比,不同入口硝酸根浓度和CODCr及低温时溶解氧对于该系统反硝化效果的影响。结果表明,系统在有溶解氧时仍有较好的反硝化效果和COD去除率,在15℃低温下,通入2·0mg/L的溶解氧也可使系统具有良好的反硝化效果。
It is experimentally studied the influence of C/N ratio,higher nitrate radical and COD_ Cr ,low temperature under aerobic condition on denitrification by a SBR and a biofilm-filter filled with porous honeycomb ceramics.The results show that DO has great effect on denitrification efficiency of this system model,The result also illustrates that the aerobic denitrification efficiency is quite well even at a low 15 ℃ temperature with DO=2.0 mg/L as comparing with anaerobic dinitrification.
