摘　　要：新型双循环两相(BICT)生物脱氮除磷工艺是以序批式活性污泥法为基础的废水处理技术。应用该工艺以城市污水为水源进行的中试试验研究结果表明,运行模式对系统反硝化和吸磷效果影响显著。在适宜的负荷和运行模式下,新工艺可实现对进水碳源的充分利用,TN和TP的平均去除率可达81.6%和90%,出水TN和TP可分别控制在15 mg/L和0.5 mg/L以下。The new biological denitrification and dephosphorization process, bi-cyclic two-phase （BICT） biological process, is based on the sequencing batch reactor activated sludge process. While using urban sewage as water sources, the pilot experimental study results show that the effects of operation running modes on the system efficiencies of denitrification and phosphorus uptake are significant. With appropriate load and operating mode,the new process can realize the full utilization of the influent carbon source. The average removal rates of TN and TP can be as high as 81.6% and 90% ,respectively. The effluent TN and TP can be controlled at 15 mg/L and 0.5 mg/L below, respectively.
