| 摘 要： | 实验采用人工配水,对生物膜系统中COD和氮的去除进行了研究。实验中pH控制在7.0～7.5左右,温度为20℃～28℃。本实验研究了不同溶解氧、水力停留时间和碳氮比对总氮去除率的影响。实验结果表明,生物膜系统中同时硝化和反硝化具有一定的可行性。在C/N比为8∶1,水力停留时间6h时,溶解氧为0.5～1.0mg/L时,总氮的去除率达53.6%。

| Abstract: | The removal of COD_(mn) and nitrogen in biofilm system was studied with pH controlled in 7.0~7.5 and temperature in 20℃~28℃ in the experiment. The impact of various DO, hydraulic retention time and ratio of C/N on removal efficiency of TN was discussed. Results showed that simultaneous nitrification/denitrification is feasible in biofilm system, with removal efficiency of TN up to 53.6% when C/N ratio of 8:1, hydraulic retention time of 6h and DO 0.5~1.0 mg/L. |
