摘　　要：应用复合微生物菌剂和菖蒲对复合垂直流人工湿地系统进行生物强化研究,探讨其能否提高系统的处理效果。将该系统在无强化、复合微生物菌剂强化和植物及复合微生物菌剂同步强化3种工况下的试验处理效果进行比较,发现植物及复合微生物菌剂同步强化工况下的系统处理能力有显著提高,COD和TP出水浓度达到GB 18918—2002《城镇污水处理厂污染物排放标准》一级A排放标准,NH+4-N出水浓度达到二级A排放标准。Low nitrogen and phosphorus removal capacity had been revealed when integrated vertical flow constructed wetland were on trial to treat urban sewage. In this study,compound bacterium agent and acorus calamus were applied for biological enhancement for an integrated vertical flow constructed wetland. Comparisons had been made on the system's treatment effects under different conditions such as non-enhancing,compound bacterium agent enhancing,and cogradient enhancing of acorus calamus and bacterium agent,and the results showed that after the cogradient enhancement,the system' s purifying capacity had been enhanced greatly. The COD and TP of effluent could reach Rank A in the first class discharge standard of China and the effluent's NH+4-N could reach Rank A in second class discharge standard.
