中文摘要	为了解美人蕉、香根草和荆三棱3种水生植物带改善河水水质的作用,在中试规模上研究了它们处理受污染河水的效果。结果表明,有植物带对污染物降解的效果好于无植物带,其中荆三棱带效果最好,它在整个运行期间对COD、氨氮NH4+-N和总磷TP的去除效果分别为44.1%、78.7%和71.4%。对出水溶解氧与水温进行了考察,3种植物带中,荆三棱带的水温和溶解氧最低。各种植物带对河水中污染物的去除和改善水环境条件等方面有不同的特点,在河岸带修复时应尽可能保证水生植物的多样性。; Polluted river water was treated with Canna glauca l.,Vetiveria zizanioides,and Scirpus yagara ohw to investigate their impact on river water quality in pilot-scale tests.The results show that treatment with aquatic plants gives better water quality than in areas without aquatic plants with Scirpus yagara ohw giving the best results.On average,the Scirpus yagara ohw removes 44.1% of the COD,78.7% of the ammonia,and 71.4% of the total phosphorous.Measurements of the dissolved oxygen and temperature of the effluent from the three treatment zones show that the temperature and dissolved oxygen are the lowest in the Scirpus yagara ohw zone.Three different aquatic plants have different abilities to remove water pollutants and improve water quality;therefore,biological diversity is a key component of river ecology restoration.; 国家“十五”重大科技攻关项目(2003AA601080)
