| 摘 要： | 通过梯级河岸人工湿地的数值模拟,以总磷(TP)在梯级河岸人工湿地的运移为例,通过流场、TP浓度场和TP运移归宿的分析,探讨了植物根系和填料对TP运移和去除效果的影响.研究结果表明,对TP而言,有植物湿地的去除率均大于相应无植物湿地的去除率;含豆石层(降解系数和渗透系数相对较大)湿地的去除率均略大于相应无豆石层湿地的去除率. |
| 关 键 词： | 梯级河岸人工湿地 数值模拟 植物根系 填料 去除率 |

| Abstract: | Riparian constructed wetlands have been promoted as a means of reducing nutrient inputs from nonpoint pollution and river pollution.Riparian constructed wetlands have combined the treatment principles of both natural riparian wetlands and constructed wetlands.A three dimensional numerical model was developed for modeling TP transport in cascaded riparian constructed wetlands.The effects of plant roots and filler to TP transport and removal efficiency were discussed from the aspects of the flow fields,TP concentration fields and the fate of TP.The removal efficiencies of the riparian constructed wetlands with plants are higher than the corresponding riparian constructed wetlands without plants.The removal efficiencies of the riparian constructed wetlands with pisolite(degradation parameter and conductivity parameter were relatively larger) are a little higher than the corresponding riparian constructed wetlands without pisolite. |
| Keywords: | cascaded riparian constructed wetland numerical modeling plant roots filler removal efficiency |
