| 摘 要： | 就不同季节条件下水力停留时间分别为1、3和5d时，水平潜流人工湿地系统对化粪池污水的净化效果进行了研究．结果表明，在同一季节，随着水力停留时间的延长，该系统对COD、TP、TN等3个指标的去除率明显提高，3d去除率明显高于1d，系统在水力停留时间5d时对COD、TP、TN的去除效果虽比3d有所提高，但增幅不明显．在夏、秋、冬3个季节，系统对COD的去除率分别达到43．48％～83．33％、53．52％～86．32％和33．33％～63．77％，对TP的去除率分别达到33．28％-66．9％、22．14％～55．85％和12．69％～42．71％，但对TN的去除效果较差，平均去除率只有19．09％．

| Abstract: | The purifying efficiency of horizontal-flow constructed wetlands on septic tank sewage in was investigated,when the hydraulic retention time(HRT) was 1,3 and 5 d respectively under different seasons.The results showed that the removal efficiencies of the organics,total phosphorous(TP) and total nitrogen(TN) in constructed wetlands were improved significantly with the extension of HRT under the same season.The removal rate of 3 d HRT was obviously higher than that of 1 d HRT,and the removal rate of 5 d HRT was better than that of 3 d HRT,but the removal efficiency was not very obvious with the increment of HRT.The removal rates of COD(Chemical oxygen demand) were 43.48%-83.33%,53.52%-86.32%,33.33%-63.77%,in summer,autumn and winter,respectively.The removal rates of TP could reach up to 33.28%-66.9%,22.14%-55.85%,12.69%-42.71% in the three seasons,but the removal rate of TN was very low,with an average of 19.09%. |
