选取黄菖蒲、旱伞草、水葫芦等为浮岛的复合植物,以水竹为基质制作生态浮岛,分别在以太阳能为动力的曝气设备下进行单倍曝气和双倍曝气的实验下,比较来探究其净化污染水体的效能和 N、P等富营养物质去除率.实验表明:在室温条件下,双倍曝气情况COD、总氮和氨氮的去除率分别是35.5%,71.4%和81.5%,溶解氧浓度迅速提高达临界值7.8mg/L至平衡态.单倍曝气情况下,总磷的去除率较高为82.2%,该生态浮岛对污染水体中的COD、氨氮、总氮和总磷等具有很好的净化效果,实现了对污染水体的快速修复作用.%Select Huang Changpu,such as water hyacinth,Cyperus alternifolius composite plant floating island,water for ecological floating island to the matrix,respectively,single and double aeration aeration aeration equipment for power under the solar experiments to explore the removal rate of purification of the polluted water efficiency size and N,P and other rich nutrition level.The experiment shows that under the condition of double aeration,the removal rate of COD and total nitrogen and ammonia nitrogen is higher at room temperature. The removal rates of total nitrogen and ammonia nitrogen are 35.5%,71.4% and 81.5%respectively,and the dissolved oxygen concentration increases rapidly to a critical value of 7. 8mg/L to equilibrium. Single aeration conditions,the phosphorus removal rate was as high as 82.2%,the ecological floating bed has good purification effect on polluted water in COD,ammonia nitrogen,total nitrogen and total phosphorus,to achieve a rapid repair of polluted water.
