| 摘 要： | 构建由潜流人工湿地和表流人工湿地串联而成的复合人工湿地系统,研究了复合人工湿地脱氮除磷效果以及温度和基质对人工湿地脱氮除磷效果的影响。结果表明,复合人工湿地TP、氨氮平均去除率为33.64%、57.24%;水温降低会导致人工湿地氮磷去除率下降;基质为粗砂的潜流人工湿地脱氮除磷能力大于基质为砾石的潜流人工湿地。

| Abstract: | This paper studied the efficiency of constructed wetlands to nitrogen and phosphorus re- moval as well as temperature and substrate on the constructed wetlands nitrogen and phosphorus re- moval by constructed an integrated constructed wetland which was composed of subsurface flow Con- structed wetland and surface flow constructed wetland in series. The results show that the average re- moval rates of TP and NH4 - N were 33.64% and57.24%. The water temperature reduction would lead to decline of the nitrogen and phosphorus removal rate of constructed wetland. The efficiency of nitrogen and phosphorus removal of subsurface flow with coarse sand substrate was greater than the one with gravel substrate. |
