摘　　要：选取薏苡作为湿地植物构建潜流人工湿地系统,研究该系统对公园厕所污水的处理效果。结果表明,人工湿地系统中薏苡长势良好,在水力负荷8 cm/d、水力停留时间1.5 d情况下,该系统对COD、氨氮、总氮和总磷的平均去除效率分别为56.4%、53.3%、49.8%和73.0%;无植物空白对照系统对COD、氨氮、总氮和总磷的平均去除效率分别为46.0%、50.1%、49.1%和68.1%。薏苡应用于湿地污水处理系统,不仅可行,还能产生较高的经济效益,具有广阔的应用前景。Subsurface constructed wetland planted with Coix was used for the treatment of toilet wastewater from parks.The results showed that Coix grew well in constructed wetland.With a hydraulic loading rate of 8 cm/d and a hydraulic retention time of 1.5 d,the average removal efficiencies of COD,NH_4-N^+,TN and TP for constructed wetland were 56.4%,53.3%,49.8% and 73.0%,respectively.While for the system without Coix,the average removal efficiencies of COD,NH_4-N^+,TN and TP were 46.0%,50.1%,49.1% and 68.1%,respectively.Coix can be applied to constructed wetland due to its possibility of pollutants removal as well as its higher economic benefit.
