摘要
提出了一种组合式垂直流人工湿地处理工艺,并研究了其对生活污水的处理效果。在水力负荷100 mm/d的工况下,生活污水中有机物的去除主要集中在组合式垂直流人工湿地的第一级,其去除速率常数显著高于后面两级(P<0.05)。人工湿地系统对污水中化学耗氧量、总氮、总磷的去除率分别为90.1%、53.7%和43.7%,相应的去除速率常数分别为88.0、29.2和21.2。
The efficacy of sewage treatment by a hybrid vertical constructed wetland was investigated.When the hydraulic loading was 100 mm / d,the organic matter in sewage was mainly removed by the first chamber of the system,and the removal rate was significantly higher than that in the other two chambers（ P〈0. 05）.The percentage of removal of chemical oxygen demand,total nitrogen,and total phosphorus were 90. 1%,53. 7%,and 43. 7%,respectively. The degradation constants of these three parameters were 88. 0,29. 2,and21. 2,respectively.
