This study investigated the removal of selected pharmaceuticals and personal care products (PPCPs) in a simulated managed aquifer recharge (MAR) system. The PPCPs included antibiotic, antiepileptic, antihypertensive, anti-inflammatory, and antilipidemic drugs, contrast media, herbicides, and stimulants. We first monitored the occurrence and fate of 22 PPCPs at a water reclamation facility (WRF) in Korea, and found carbamazepine and primidone were not readily removed (below 25% removal in average) by the WRF. This reclaimed water passed through a laboratory-scale soil column set-up at 0.5 m/d over one year, simulating MAR system. Atenolol, propranolol, and trimethoprim exhibited higher removal rates (>80%) than other PPCPs through the simulated MAR, while atrazine, carbamazepine, lincomycin, primidone, and sulfamethazine were not readily removed, exhibiting removal rates below 20%. It can be efficient to monitor and manage these recalcitrant compounds at MAR systems to improve water quality.
本研究考察了在模拟含水层补给（MAR）系统中去除选定的药品和个人护理产品（PPCPs）的情况。PPCPs 包括抗生素、抗癫痫药、抗高血压药、消炎药和抗血脂药、造影剂、除草剂和兴奋剂。我们首先在韩国的一家水再生设施（WRF）监测了 22 种 PPCPs 的发生和命运，发现卡马西平和苯巴比妥不易被 WRF 去除（平均去除率低于 25%）。这些再生水通过实验室规模的土壤柱在一年中以 0.5 m/d 的速度通过，模拟 MAR 系统。在模拟 MAR 系统中，阿替洛尔、普萘洛尔和甲氧苄啶的去除率高于其他 PPCPs（>80%），而莠去津、卡马西平、林可霉素、苯巴比妥和磺胺甲噁唑不易去除，去除率低于 20%。在 MAR 系统中监测和管理这些难去除的化合物可以有效地提高水质。
