摘　　要：河源市城南污水处理厂利用垂直流人工湿地对该厂A2-O工艺处理的尾水进行深度处理,研究了人工湿地对尾水中TN、NH4+-N、TP、COD、BOD5的去除效果。结果表明:人工湿地对污水处理厂尾水具有较好的深度处理效果,垂直流人工湿地处理系统对尾水中TN、NH4+-N、TP、COD和BOD5平均去除率分别达到97.4%、97.8%、95.06%、91.87%和95.87%以上,其出水水质基本达GB 18918—2002《城镇污水处理厂污染物排放标准》一级A标准,地表水Ⅲ类标准。The essay, with the Sewage Treatment Plant of the South of Heyuan City as its platform, and sanitary waste as its experimental water, aims at studying the removal efficiency of A^2O-construced wetland combined process for organic matter. The result of the research indicates that TN,NH4 -N,TP and COD removal efficiency of A^2O-construced wetland combined process is up to 97.4% ,97.8% ,95.06% , 91.87% and 95.87% , respectively, basically reaching A standard of the first-order in ＂Urban Sewage Treatment Plants Standards for Pollutants Discharge＂（ GB 18918-2002）, as well as surface iil class standards.
