摘要:
污水印记药物(WWMPs)是城市河流中新兴的污染物。采用旱伞草、灯芯草和菖蒲3种挺水植物，以阿奇霉素(AZM)、磺胺噻唑(STZ)、布洛芬(IBU)、双氯芬酸(DCF)、扑热息痛(PRC)、阿替洛尔(ATL)、氯贝酸(CLF)、卡马西平(CBM)和咖啡因(CAF)共9种WWMPs作为目标物，通过测定水相中4种常规指标和水相、沉积相、植物中WWMPs浓度的变化，探究单种植物人工生态系统对城市河流水质的净化效果。在无植物系统中，4种常规指标COD、TP、TN、NH4+-N浓度无明显变化；而在水生植物生态系统中，4种常规指标浓度的下降率分别为49.5%、52.1%、57.8%和74.2%。相比于无植物系统，水生植物生态系统对水相中的WWMPs有明显的去除效果，尤其是对CBM、IBU、ATL和PRC，去除率大于33.8%；旱伞草和菖蒲人工生态系统对沉积相中的ATL、AZM、CBM、IBU和PRC等去除效果不明显；在植物体中,无论是水上还是水下部分，对CAF、CBM和CLF的吸收效果均良好。研究结果表明，水生植物人工生态系统可有效去除城市河流中的WWMPs以及常规污染物，是改善城市河流水质的有效手段。
Abstract:
Wastewater-marking pharmaceuticals (WWMPs) are emerging contaminants in urban rivers. Nine WWMPs including azithromycin (AZM), sulfathiazole (STZ), ibuprofen (IBU), diclofenac (DCF), paracetamol (PRC), atenolol (ATL), clofibrate (CLF), carbamazepine (CBM) and caffeine (CAF) were selected as the target compounds, and purification effects of artificial ecosystem with different hydrophytes (Cyperus alternifolius, Juncus effusus and Acorus calamus L.) on water quality of urban rivers were investigated by monitoring 4 conventional indicators in liquid phase and the changes of WWMPs in liquid phase, sediment and plant tissue. There were no significant changes of 4 conventional indicators (COD, TP, TN and NH4+-N) in the artificial ecosystem without plant, while their concentrations in the artificial ecosystems with hydrophyte decreased by 49.5%, 52.1%, 57.8% and 74.2%, respectively. Compared with the non-plant system, ecosystems with hydrophyte had a significant removal effect on WWMPs in liquid phase, especially for CBM, IBU, ATL and PRC, and the removal efficiencies were greater than 33.8%. The removal of ATL, AZM, CBM, IBU and PRC in sediments by the ecosystem with Cyperus alternifolius and Acorus calamus L. was not remarkable. In plant tissue, no matter above-water and underwater parts, good absorption effects of CAF, CBM and CLF were obtained. Artificial ecosystem with hydrophyte can effectively remove WWMPs and conventional pollutants in urban rivers, and is an effective means for improving water quality of urban rivers.
