摘　　要：通过小型垂直流与潜流人工湿地实验,监测了水力停留时间为50小时下的CODCr、TP、NO3--N、NH3-N等指标,旨在通过实验,比较垂直流芦苇人工湿地与潜流芦苇人工湿地对化粪池出水的净化效果.结果表明,垂直流芦苇人工湿地对CODCr、NH3--N去除相对较好;而潜流芦苇人工湿地对NO3--N去除相对较好;而对TP的去除两者没有太大差别.The technology of constructed wetland has good disposal effect and low operation cost, which is a new technology in wastewater treatment. Some parameters, such as CODer, TP, NO3^--N, NH3-N, were measured within four-month operation of compound flow in constructed wetland. It shows that vertical-flow of the efficiency of removing CODCr, NH3- N is better; but subsurface-flow removing NO3^- -N is better. Phosphorus can be removed from wastewater exactly through rational process. There is no difference between vertical-flow and subsurface-flow on removing of phosphorus.
