摘　　要：[目的]研究曝气与生态浮床组合处理景观水体富营养化的效果。[方法]选取黄花鸢尾和花叶菖蒲组合作为生态浮床,将生态浮床和曝气-生态浮床进行对比研究,研究曝气-生态浮床对景观水体中总氮(TN)、总磷(TP)的去除效果。[结果]生态浮床对景观水体中的TN、TP的去除率分别为85.14%和40.98%;曝气-生态浮床对景观水体中的TN、TP的去除率分别为93.17%和53.28%。在生态浮床处理景观水体中,增加曝气能够对景观水体中TN、TP的去除率提高10%左右。[结论]曝气-生态浮床能够很好地去除景观水体中TN、TP,是处理景观水体富营养化的有效方法。[Objective]To the effects of aeration and ecological floating bed treatment on eutrophication of landscape water body. [Method]Iris pseudacorus Linn and Acorus tatarinowii cv. variegata were selected as the ecological floating bed,and comparative study was conducted between the ecological floating bed and the aeration-ecological floating bed,the removal rate of ecological floating and the aeration-ecological floating bed on TN,TP was studied. [Result]The results showed that the removal rate of TN and TP in the landscape water by ecological floating bed was 85. 14% and 40. 98%,respectively. The removal rate of TN and TP in the landscape water by aeration-ecological floating bed was 93. 17% and 53. 28%,respectively. The removal rate of TN and TP in landscape water can be increased by 10% in the treatment of landscape water by adding the aeration. [Conclusion]The combination of aeration and ecological floating bed can remove TN and TP in the landscape water well,which is an effective method to treat the eutrophication of landscape water body.
