曝气-生态浮床处理景观水体富营养化研究

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。

Study on Eutrophication of Landscape Water Body Treated by Aeration-ecological Floating Bed

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.
