| 摘 要： | 在上海市某区人工湿地中,选取了4个不同尺度的人工湿地工程进行水质监测,研究人工湿地全年对污染物及病原菌的去除效果.在稳定运行状态下,季节变化对于TP、细菌总数和粪大肠杆菌群的去除效果影响不大,但是对于CODCr和NH_3-N的影响作用比较大.4个人工湿地系统对于CODCr、NH_3-N、TP、细菌总数和粪大肠杆菌群均有较为稳定的去除效果,出水均能达到《城镇污水处理厂污染物排放标准》(GB18918-2002)中一级B排放标准.

| Abstract: | Four constructed wetlands of different scales from one district in Shanghai were selected to research the removal effect of contaminant and pathogenic bacteria in the systems all year round.In the condition of stable operation,seasonal variation has little influence on the removal effect of TP,total bacterial count and fecal coliforms,however,it has great influence on the removal effect of CODCrand NH_3-N.The four systems had steady removal efficiencies for CODCr,NH_3-N,TP,total bacterial count and fecal coliforms,the effluents had reached the level 1 Bstandard of GB18918-2002. |
