Each year, large amounts of plastic waste are generated and must be appropriately disposed. In this work, we studied the feasibility of using plastics as wetland substrates as an alternative plastic waste disposal method and the ability of the constructed wetland to remove pharmaceuticals and personal care products (PPCPs) from contaminated water. Wetland microcosms were constructed using polycarbonate, polyethylene terephthalate, quartz sand, and ceramsite substrates. Lake water spiked with methyl-paraben, ibuprofen, triclosan, 4-methybenzylidene camphor, carbamazepine, and 17α-ethinyl estradiol at 5 μg L⁻¹ was continuously loaded to the microcosms with a hydraulic retention time of approximately 11 days. After 70 days, methyl-paraben, triclosan, and 4-methybenzylidene camphor were effectively removed regardless of the substrate. However, ibuprofen, carbamazepine, and 17α-ethinyl estradiol were partially removed, and the removal efficiency was the best in wetlands with ceramsite substrate. Carbamazepine was the most persistent among the tested compounds. Phospholipid fatty acid (PLFA) analysis revealed that ceramsite supported the highest microbial biomass per bulk volume of substrate followed by quartz sand, polycarbonate, and polyethylene terephthalate, which might be related to the PPCP removal potential of the wetland microcosms.

每年都会产生大量的塑料废物，必须进行适当处理。在这项工作中，我们研究了将塑料用作湿地基质作为替代性塑料废物处理方法的可行性，以及人工湿地从污染水中去除药品和个人护理产品（PPCP）的能力。湿地缩影是使用聚碳酸酯，聚对苯二甲酸乙二醇酯，石英砂和陶粒基材构造的。湖水中掺有对羟基苯甲酸甲酯，布洛芬，三氯生，4-甲基亚苄基樟脑，卡马西平和17α-乙炔雌二醇，浓度为5μgL ^-1将其以约11天的水力停留时间连续加载至缩微膜。70天后，无论底物如何，对羟基苯甲酸甲酯，三氯生和4-甲基亚苄基樟脑均被有效去除。然而，布洛芬，卡马西平和17α-乙炔雌二醇被部分去除，在以陶粒为底物的湿地中去除效率最高。卡马西平是测试化合物中最持久的。磷脂脂肪酸（PLFA）分析显示，陶粒所支持的单位体积基质中微生物生物量最高，其次是石英砂，聚碳酸酯和聚对苯二甲酸乙二酯，这可能与湿地微观世界的PPCP去除潜力有关。
