摘　　要：在室内设计4组不同植物群落和1组无植物对照净化生活污水,定期测定污水中COD、总氮、氨氮和总磷浓度,从中挑选出对污染物去除效率较好的群落组合。结果表明:茭草+金鱼藻+金鱼藻群落配置净化污水效果最好,COD、总氮、氨氮和总磷净化效率分别为75.0%、97.3%、90.0%和84.2%,对照净化效果最差,COD、总氮、氨氮和总磷净化效率分别为32.5%、23.8%、38.3%和26.4%。5个试验组的净化能力强弱依次为:群落1>群落2>群落4>群落3>对照。Some plant combination communities with better living sewage purification effect were selected by la- boratory simulation with different plant species. Four groups of plant combination and a control group without any plants were designed in the experiment, and the concentration values of COD, total nitrogen, ammonia nitrogen and total phosphorus in the treated sewage samples were periodically determined. The experiment showed that the best purification results were obtained by the Community Type 1 and the removal efficiency for COD, total nitrogen, am- monia nitrogen and total phosphorus efficiency was 75.0% , 97.3% , 90.0% and 84.2% individually. Whereas the worst purification effect was resulted from the control group, whose removal efficiency for COD, total nitrogen, ammonia nitrogen and total phosphorus was 32.5% , 23.8% , 38.3% and 26.4% respectively. The purification capacity of the five treatment communities was ranked in the declining order as Community 1 〉 Community 2 〉 Community 4 〉 Community 3 〉 Control.
