Abstract：
Pharmaceuticals and personal care products (PPCPs) are insufficiently degraded in saline wastewater treatment processes and are found at high concentrations and detection frequencies in aquatic environments. In this study, the wetland plant Thalia dealbata was selected using a screening plant experiment to ensure good salt tolerance and high efficiency in removing PPCPs. An electric integrated vertical-flow constructed wetland (E-VFCW) was developed to improve the removal of PPCPs and reduce the abundance of antibiotic resistance genes (ARGs). The removal efficiency of ofloxacin, enrofloxacin, and diclofenac in the system with anaerobic cathodic and aerobic anodic chambers is higher than that of the control system (41.84 ± 2.88%, 47.29 ± 3.01%, 53.29 ± 2.54%) by approximately 20.31%, 16.04%, and 35.25%. The removal efficiency of ibuprofen in the system with the aerobic anodic and anaerobic cathodic chamber was 28.51% higher than that of the control system (72.41 ± 3.06%) and promotes the reduction of ARGs. Electrical stimulation can increase the activity of plant enzymes, increasing their adaptability to stress caused by PPCPs, and PPCPs are transferred to plants. Species related to PPCPs biodegradation (Geobacter, Lactococcus, Hydrogenophaga, and Nitrospira) were enriched in the anodic and cathodic chambers of the system. This study provides an essential reference for the removal of PPCPs in saline-constructed wetlands.
摘要：
药物和个人护理产品（PPCP）在含盐废水处理过程中降解不足，并且在水生环境中的浓度和检测频率很高。在这项研究中,通过筛选植物实验选择了湿地植物Thaliadealbata，以确保良好的耐盐性和去除PPCP的高效率。开发了一种电集成垂直流人工湿地（E-VFCW），以改善PPCP的去除并减少抗生素抗性基因（ARG）的丰度。氧氟沙星的去除效率,恩诺沙星,和双氯芬酸在有厌氧阴极和好氧阳极室的系统中高于控制系统（41.84±2.88％，47.29±3.01%,53.29±2.54%）约为20.31%，16.04%,和35.25%。在装有好氧阳极和厌氧阴极室的系统中，布洛芬的去除效率比控制系统的去除效率（72.41±3.06％）高28.51％，并促进了ARGs的减少。电刺激可以增加植物酶的活性，增加它们对由PPCPs引起的压力的适应性，和PPCPs转移到植物。与PPCPs生物降解相关的物种(Geobacter，乳球菌,Hydrogenophaga,和Nitrospira）在系统的阳极和阴极室中富集。该研究为盐渍湿地中PPCPs的去除提供了必要的参考。
