The aim of this study was to investigate the removal of ibuprofen in laboratory scale constructed wetlands. Four (planted and unplanted) laboratory‐scale horizontal subsurface flow constructed wetlands were supplemented with ibuprofen in order to elucidate (i) the role of plants on ibuprofen removal and (ii) to evaluate the removal performance of a bioaugmented lab scale wetland. The planted systems showed higher ibuprofen removal efficiency than an unplanted one. The system planted with Juncus effusus was found to have a higher removal rate than the system planted with Phalaris arundinacea. The highest removal rate of ibuprofen was found after inoculation of gravel previously loaded with a newly isolated ibuprofen‐degrading bacterium identified as Sphingobium yanoikuyae. This experiment showed that more than 80 days of CW community adaptation for ibuprofen treatment could be superseded by bioaugmentation with this bacterial isolate.

通过使用含有可降解布洛芬的 Sphingobium yanoikuyae 生物膜的砾石进行生物强化，增加人工湿地中布洛芬的降解


本研究的目的是调查实验室规模的人工湿地中布洛芬的去除情况。四个（种植的和未种植的）实验室规模水平地下流人工湿地补充了布洛芬，以阐明（i）植物对布洛芬去除的作用和（ii）评估生物增强实验室规模湿地的去除性能。种植的系统比未种植的系统显示出更高的布洛芬去除效率。发现种植灯心草的系统比种植Phalaris arundinacea 的系统具有更高的去除率。在接种先前装载有新分离的布洛芬降解细菌（被鉴定为Sphingobium yanoikuyae）的砾石后，发现布洛芬的去除率最高。该实验表明，CW 群落对布洛芬治疗的 80 多天适应可以被这种细菌分离物的生物强化所取代。
