摘要
      随着技术的发展，抗生素和抗生素抗性基因这两种新的污染物已经成为全球环境和健康问题。在污水中广泛检测到各种抗生素和ARGs。与传统的污水处理厂相比，人工湿地具有以下优点：能耗低、运行管理成本低，并且在去除抗生素和ARGs方面非常有效。本研究综述了影响CWs去除废水中抗生素和ARGs效率的因素。总体而言，垂直流地下CWs对抗生素的去除效率最高（>60%）。此外，含有植物和基质材料（如沸石和砖颗粒）的水煤浆对抗生素的去除效率很高（73%-99.15%）。上行地下水煤浆更能去除ARGs（63.76%-96.83%）。此外，植物的存在促进了水煤浆中废水中ARGs的去除。此外，水煤浆中的微生物对ARGs的去除有很大影响，即水煤浆通过直接过滤微生物来去除废水中的ARGs。然而，有必要进行进一步的研究，以进一步了解CWs中废水中抗生素和ARGs的消除机制。
Abstract
With the development of technology, two new pollutants, antibiotics as well as antibiotic resistance genes (ARGs), have become global environmental and health problems. Various antibiotics and ARGs have been extensively detected in sewage. Compared with traditional wastewater treatment plants, constructed wetlands (CWs) show the following advantages: low energy consumption and low operation and management costs as well as being very efficient at removing antibiotics and ARGs. This study reviewed the factors affecting the efficiency of CWs in their elimination of antibiotics and ARGs from wastewater. Overall, the vertical-flow subsurface CWs showed the highest removal efficiencies for antibiotics (>60%). In addition, CWs with plants and substrate materials such as zeolite and brick pellets were highly efficient at removing antibiotics (73%–99.15%). Up-flow subsurface CWs were better at removing ARGs (63.76% to 96.83%). In addition, the presence of plants promoted the elimination of ARGs from wastewater in CWs. Moreover, microorganisms in CWs have a great impact on the removal of ARGs, that CWs remove ARGs from wastewater by directly ieliminating microorganisms. However, further research is necessary to further understand the mechanisms of the elimination of antibiotics and ARGs from wastewater within CWs.
