Managed aquifer recharge (MAR) is a natural water treatment process that induces surface water to flow in response to a hydraulic gradient through soil/sediment and into a vertical or horizontal well. It is a relatively cost-effective, robust and sustainable technology. Detailed characteristics of bulk organic matter and the occurrence and fate of pharmaceutically active compounds (PhACs) during MAR processes such as bank filtration (BF) and artificial recharge (AR) were reviewed. Understanding the fate of bulk organic matter during BF and AR is an essential step in determining pre- and/or post-treatment requirements. Analysis of organic matter characteristics using a suite of analytical tools suggests that there is a preferential removal of non-humic substances during MAR. Different classes of PhACs were found to behave differently during BF and AR. Antibiotics, non-steroidal anti-inflammatory drugs (NSAIDs), beta blockers, and steroid hormones generally exhibited good removal efficiencies, especially for compounds having hydrophobic-neutral characteristics. However, anticonvulsants showed a persistent behavior during soil passage. There were also some redox-dependent PhACs. For example, X-ray contrast agents measured, as adsorbable organic iodine (AOI), and sulfamethoxazole (an antibiotic) degraded more favorably under anoxic conditions compared to oxic conditions. Phenazone-type pharmaceuticals (NSAIDs) exhibited better removal under oxic conditions. The redox transition from oxic to anoxic conditions during soil passage can enhance the removal of PhACs that are sensitive to redox conditions. In general, BF and AR can be included in a multi-barrier treatment system for the removal of PhACs.
含水层人工补给（MAR）是一种自然水处理过程，它通过水力梯度诱导地表水在土壤/沉积物中流动，并进入垂直或水平井。它是一种相对经济、稳健和可持续的技术。本文综述了 MAR 过程（如河岸过滤（BF）和人工补给（AR））中大量有机物质的特征以及药物活性化合物（PhACs）的发生和归宿。了解 BF 和 AR 过程中大量有机物质的归宿是确定预处理和/或后处理要求的重要步骤。使用一系列分析工具分析有机物特征表明，在 MAR 过程中，非腐殖质物质优先去除。研究发现，不同类别的 PhACs 在 BF 和 AR 中的行为不同。抗生素、非甾体抗炎药（NSAIDs）、β受体阻滞剂和甾体激素通常表现出良好的去除效率，尤其是具有疏水性-中性特征的化合物。然而，抗惊厥药在土壤迁移过程中表现出持久的行为。还有一些依赖氧化还原的 PhACs。例如，可吸附有机碘（AOI）测量的 X 射线造影剂和磺胺甲恶唑（一种抗生素）在缺氧条件下比好氧条件下更有利于降解。苯并恶嗪类药物（NSAIDs）在好氧条件下具有更好的去除效果。土壤迁移过程中从好氧到缺氧条件的氧化还原转变可以增强对氧化还原条件敏感的 PhACs 的去除。一般来说，BF 和 AR 可以纳入多屏障处理系统，以去除 PhACs。
