摘　　要：利用中试规模的美人蕉河岸带处理受污染河水,并与无植物空白带的处理效果进行对比。结果表明,美人蕉河岸带在夏、秋季改善河水水质的效果好于冬、春季。在夏季美人蕉河岸带对COD、NH4+-N、TP和浊度的去除率分别为45.29%、68.06%、77.78%、99.23%,在冬季对河水水质也有一定程度的改善。美人蕉河岸带可以稳定河水的温度及降低河水早晚温差,起到了改善局部水环境的作用。美人蕉河岸带与空白带的对比试验结果表明,植物在去除污染物、改善局部水环境方面起着重要作用。The pilot-scale Canna glauca L. riparian zone was used to treat polluted river water, and its treatment effect was compared with that in control zone without plants. The results show that the Canna glauca L. zone gives better water quality in summer and autumn than in winter and spring. In summer, the removal rates of COD, NH4^＋ - N, TP and turbidity are 45.29%, 68.06%, 77.78% and 99.23%. The water quality is improved to some extent in winter. The Canna glauca L. zone can stabilize river temperature, reduce temperature difference between evening and morning and improve water microenvironment locally. Comparisons between treatments with the Canna glauca L. and without aquatic plants show that the plants play an important role in removing pollutants and improving local microenvironment of water.
