摘　　要：在水污染处理方面,生态浮床与传统物理化学方法相比,因其具有较好的景观效应及生态效应而越来越多地被利用到景观水体的净化中。选取千屈菜为研究植物,利用人工模拟方法,设计连续进出水试验装置,调节水力负荷,模拟自然河流状态,将丽娃河水泵入试验系统,水体经过生态浮床系统,由出水口溢流排出。实验数据表明(根据《地表水环境质量标准》(GB3838-2002),试验系统进水属于Ⅳ类水,出水属于Ⅲ类水,且系统对NH4+-N和TP的去除率最高可达90%和41%。In terms of water pollution treatment, ecological floating bed has been used widely for landscape water purification because of its better landscape effect and ecological effect compared with traditional physical and chemical methods. Lythrum salicaria was taken as research object. Continuous inlet and outlet water test devices were designed by artificial simulation method which simulated natural rivers state by regulating hydraulic loading. Liwa river water was pumped into the test devices, ran through ecological floating beds, and outflowed by an water outlet. According to Environmental Quality Standards for Surface Water （GB3838-2002）, the water quality of inflow was at Grade Ⅳ, and the outflow was at Grade Ⅲ. The results showed the maximum removal of NH4＋-N and TP were 90% and 41%,
