| 摘 要： | 研究了四种陶粒组合、一种石灰石碎石5套复合垂直流人工湿地在不同季节处理生活污水的运行效果。结果表明:陶粒组合人工湿地系统对COD、TP、NH3-N的去除效果均优于石灰石碎石湿地;复合垂直流人工湿地对COD的去除效果在冬季有所下降,但仍保持在50%以上;湿地系统对TP去除率受季节性变化影响不显著,但随着复合垂直流人工湿地系统的运行,基质层对TP的吸附逐渐饱和,去除效率缓慢下降;1号~5号人工湿地对氨氮的去除率分别从秋季42.0%、55.1%、61.1%、49.9%、50.2%下降至冬季21.9%、31.0%、36.5%、28.5%、29.2%,春、夏季处理效率开始回升,并保持稳定的状态。

| Abstract: | The removal effect of domestic wastewater of five types of integrated vertical flow constructed wetlands in different seasons was studied.Four different combinations of ceramisitesl and limestone gravel were selected as the media in the wetland.The result showed that:the removal effect of ceramisites combined constructed wetland was better than limestone gravel wetland;the removal efficiency of integrated vertical flow constructed wetland was decreasing for COD,but it was still over 50%;the removal efficien... |
