摘　　要：通过在同种基质上种植相同数目的芦苇,研究了垂直流人工湿地对化粪池出水的净化效果,以及不同水力停留时间对污水净化效果的影响。结果表明,同种填料、不同水力停留时间,对污水中TP、NH4+-N、CODcr的净化效果不同。由于芦苇根系和微生物的吸收与分解作用,以及基质的吸附作用,种植芦苇的人工湿地出水水质要比未种芦苇的好。Reed was planted in the same substrates. In this paper, the efficiency of constructed wetland and the effect of hydraulic retention time on the purifying efficiency for septic tank effluent treatment were studied. The results showed that the wastewater purifying efficiency for TP,NH4^＋ - N ,COD were significantly different with hydraulic retention time. Under the combination function of the absorption and decomposition of reed roots and microorganisms as well as the absorption of substrates, the effluent quality from the vertical -flow constructed wetland planted with reed was better than that from the constructed wetland without reed.
