Effect of immobilized bacteria and algae filler on enhanced nitrogen and phosphorus removal in constructed wetland

  • 摘要: 针对人工湿地氮、磷去除效果较差的现状,以固定化菌和固定化菌藻作为基质填充,探讨对照(砾石)组、固定化菌组和固定化菌藻组在人工湿地中对氮、磷的去除效果。结果表明:固定化菌组和固定化菌藻组增强了湿地体系耐负荷冲击能力及稳定性,在湿地运行初期便可快速去除水体中的污染物,固定化菌藻组、固定化菌组和对照组分别在湿地运行的第40天、48天和56天开始稳定出水,固定化菌组和固定化菌藻组出水水质稳定性均优于对照组,且达到GB 18918—2002《城镇污水处理厂污染物排放标准》一级A标准;固定化菌藻组中的藻粉及其吸附的有机物可作为补充碳源,强化氮的去除,固定化菌藻组出水的化学需氧量(CODCr)与氨氮(NH3-N)、总磷(TP)浓度达到GB 3838—2002《地表水环境质量标准》Ⅴ类水质标准,其对CODCr、NH3-N、TN、TP的去除率分别为58.10%、81.47%、86.70%和85.54%。
