| 摘 要： | 本研究通过构建水平潜流人工湿地来进行富营养化湖水的净化试验,结果表明,在0.64 m.d-1的高水力负荷条件下,分别具有3种植物(茭白、水葱和鸢尾)的人工湿地系统对富营养化湖水有较好的净化效果(对有机污染物COD、NH4+-N、NO3--N、TN和TP的去除率分别为29.2%~39.1%、37.5%~47.2%、70.3%~74.9%、48.6%~59.1%、和54.6%~57.3%).有植物的人工湿地系统与无植物的空白湿地系统相比较,尽管对COD和NO3--N的去除率差异不显著,但对NH4+-N、TN和TP的去除率都是有植物的人工湿地系统显著好于无植物的空白湿地系统,证明植物对人工湿地系统功能的发挥具有重要作用. |

| Abstract: | Field experiment was made on purifying eutrophic water of Taihu Lake using horizontal subsurface flow constructed wetlands.The results indicated that under the high hydraulic loading rates of 0.64 m d-1,three constructed wetlands planted respectively with Zizania caduciflora,Scirpus validus and Iris pseudacorus have marked effects on purifying polluted lake water.The average removal rates of chemical oxygen demand(COD),ammonia nitrogen(NH4+-N),nitrate nitrogen(NO3——N),total nitrogen(TN) and total phosphorou... |
