摘　　要：构建一座仿生塔式人工湿地水质净化系统,以生活污水为处理对象,研究仿生塔式人工湿地对COD,NH_(4)^(+)-N,TN,TP的去除特征、节能效果和季节演变情况。研究表明,仿生塔式人工湿地对COD,NH_(4)^(+)-N,TN,TP的年平均去除率分别为(86.8±8.4)%,(98.7±2.8)%,(67.9±18.9)%,(89.7±10.5)%其中COD,NH_(4)^(+)-N,TN去除率均呈季节性小幅度变化,而TP去除率未呈季节性变化。以中试污水处理站(日处理规模为3.2t)为例,仿生塔式人工湿地可节约电能1.954元/t(仅鼓风机和回流泵2项),节电明显,具有显著的环境效益和经济效益,适合在分散生活污水处理领域推广。A tower constructed wetland was developed and used for purification of sewage,and researched the purification efficiency,saving engery efficiency and evolution of sewage.The results showed that the averaged removal efficiency of the COD,NH_(4)^(+)-N,TN and TP reached respectively(86.8±8.4)%,(98.7±2.8)%,(67.9±18.9)%and(89.7±10.5)%,the averaged COD,NH_(4)^(+)-N and TN removal efficiencies were changed when the variety of seasons,and the annual TP removal efficiency was stable.The tower constructed wetland can save electric charge 1.954 yuan/t when the treatment scale was 3.2 t/d.The tower constructed wetland has good environmental and economical benefits and can be utilized for purification of dispersed sewage.
