摘　　要：分别构建了传统人工浮岛和新型人工浮岛2组系统,对比考察了对主要污染物的去除效果,分析了对污染物降解的机理,比较了植株高度、根系生长及填料降解情况。结果表明,2组人工浮岛对去除COD、TN、NO3^--N、NH4^+-N等4个水质指标的差异明显(p<0.05),新型人工浮岛系统对TP的去除率为94.55%,且对TN、NO3^--N的去除效果要显著高于传统人工浮岛,其去除率分别达到了83.39%和81.50%。丝瓜络、玉米芯的添加和降解增大了污水的可生化性,强化了新型人工浮岛的脱氮除磷效果;种植了千屈菜的新型人工浮岛植株生长高度为传统人工浮岛的2.36倍。Two types of artificial floating islands(AFIs),traditional artificial floating island and new artificial floating island were constructed respectively,the main pollutants removal effects were compared and investigated,and the pollutant degradation mechanism was analyzed.The plant height,root growth and packing degradation of the two types of AFIs were compared.The results showed that,there were more significant differences between the two groups in removing COD,TN,NO3^--N and NH4^+-N(p<0.05).The removal rate of TP by the new AFI was 94.55%,and the removal efficiency of TN and NO3^--N was significantly higher than that of the traditional AFI,which was 83.39%and 81.50%,respectively;The addition and degradation of luffa sponge and corncob enhanced the biodegradability of sewage and enhanced the nitrogen and phosphorus removal efficiency of the new AFI;The plant growth height of the new type AFI planted with Purple loosestrife was 2.36 times higher than that of the traditional AFI.
