摘　　要：试验研究了芦苇和香蒲两种植物,在人工湿地系统处理微污染河水中所起的作用,考察了芦苇和香蒲人工湿地系统对CODMn、总磷、总氮的去除效果。结果表明,香蒲人工湿地系统对CODMn、总磷、总氮的平均去除率分别为37.97%、73.46%、58.53%,而芦苇人工湿地系统的平均去除率分别为28.57%、66.73%、48.32%,香蒲人工湿地系统表现出较好的除污效果,说明采用香蒲的人工湿地系统要优于采用芦苇的人工湿地系统。The effects of Phragmites communis and Typha latifolia in constructed wetland on mlcro-pollutea river water treatment were studied, the removal of CODMn, total phosphorus, total nitrogen by the wetlands planted with the said two kinds of plants respectively were investigated. The results of the test showed that, the average removal rates of CODMn, total phosphorus and total nitrogen by the wetland planted with Typha latifolia were 37.97%, 73.46% and 58.53% respectively. However, the corresponding rates were 28.57%, 66.73% and 48.32% by the wetland planted with Phragmites commumis. It could draw a conclusion that, the constructed wetland planted with Typha latifolia was superior to the wetland planted with Phragmites communis for its better pollution removal efficiency.
