摘要/Abstract

摘要： 垂直流人工湿地系统不但具有较高的水力负荷率(54～64cm·d^-1),而且对有机物和N、P都具有较高的去除效果.其对化粪池出水中的COD、BOD₅、NH₄⁺-N和总P的去除率分别为76%～87%,88%～92%,75%～85%和77%～91%.处理出水中COD、BOD₅、NH₄⁺-N和总P的平均浓度分别小于60、20、25和2.0mg·L^-1.植物种植试验结果表明,种植风车草可提高氨氮、总N和总P的去除率,分别为2%～3%、4%～6%、10%～14%.

Abstract: Vertical-flow constructed wetlands (VFCWs) system not only has a higher hydraulic loading rate (54～64cm·d^-1), but also has a good removal efficiency for organics, ammonia nitrogen (AN) and total phosphorus (TP). The removal efficiencies of COD, BOD₅, AN, and TP for septic tank effluent were 76～87%, 82～92%, 75～85% and 77～91%, respectively,and the average effluent concentrations of COD, BOD₅, AN, and TP in the treated effluent were less than 60, 20, 25 and 2.0 mg·L^-1, respectively. Acomparison of planted and unplanted columns showed that plantation of Cyperus alternifolius could increase the removal rates of AN, TN, and TP by 2～3%, 4～6%, and 10～14%, respectively.
