| 摘 要： | 为解决传统人工湿地运行过程中存在的短路问题，本研究设计了折流式人工湿地污水处理系统，并将其应用于校园生活污水处理的试验研究。为期18个月的试验研究结果表明，系统的最佳水力停留时间（Hlit）为20h。稳定HRT=20h，24℃下折流式人工湿地对COD、TN、TP去除率分别为76．40％、76．12％、65．37％；温度降至12℃时，系统对COD、TN、TP去除率分别降至67．56％、62．75％、61．33％；运行过程中前6格室和整个系统的SS去除率分别为79．5％和87％。基于试验结果，阐明了折流式人工湿地处理生活污水高效稳定的机理。

| Abstract: | To solve the operational problem of short - circuit of the constructed wetland, a baffled wetland was de- signed and constructed to treat the domestic sewage of the campus. The results of 18 month indicated that the opti- mal hydraulic retention time （HRT） was 20h. At the HRT of 20h and the temperature of 24℃, the COD, TN and TP removal rates could be respectively over 76.40%, 76. 12% and 65.37%. When the temperature decreased to 12℃, the COD, TN and TP removal rates of the system went down to 67.56% , 62.75% and 61.33%. The SS removal rate of the first 6 compartments was about 79.5% and that of the system could maintain at 87.18% during the running period. Based on the trial, it is explained how the constructed baffled wetland treat the domestic sewage with high efficiency and stability. |
