这项研究是为了评估布洛芬的去除潜力,萘普生和17-β-雌二醇在实验室规模建设的人工湿地,使用八种实验装置种植八种八种八种八种植物,用砾石基底和不使用砾石基底进行测试,用三种化合物的浓度为1、2和5mg/L的合成混合物强化,在9天的批次暴露时间内。17-β-雌二醇的去除率为94.5±2.47%,其次是布洛芬94.03±1.96%和萘普生81.57±8.74%,分别。去除量最高的处理是在不存在砾石基质的情况下进行的处理。这三种化合物的最高去除效率发生在暴露的第三天,所以它被确立为最佳停留时间。该模型最好地解释了所研究的三种化合物的吸附过程,是朗缪尔等温线.观察到的结果表明,八瓣乳杆菌可以用作人工湿地中的天然物种,以有效去除药物化合物。
通过使用莫雷洛斯州原产的大型植物,建立了人工湿地,能够去除几种对浓度变化有耐受性的药物,这构成了一种经济和可持续的替代方案,可以与被这类化合物污染的废水处理相结合。
This study was developed to evaluate the
removal potential of ibuprofen, naproxen and 17-β-estradiol in artificial wetlands constructed on a laboratory scale, using eight experimental devices planted with L. octovalvis species, tested with gravel substrate and without gravel substrate, which were fortified with synthetic mixtures at concentrations of 1, 2 and 5 mg/L of the three compounds, during a batch exposure time of nine days. The
removal efficiency for 17-β-estradiol was 94.5 ± 2.47%, followed by ibuprofen 94.03 ± 1.96% and naproxen 81.57 ± 8.74%, respectively. The treatment with the highest
removal was the one performed without the presence of gravel substrate. The highest
removal efficiency occurred from the third day of exposure for the three compounds, so it was established as the optimum residence time. The model that best explained the adsorption process of the three compounds studied, was the Langmuir isotherm. The observed results demonstrate that L. octovalvis can be used as a native species in artificial wetlands for the efficient
removal of pharmaceutical compounds.
Through the use of a macrophyte plant native to the state of Morelos, an artificial wetland was built, which was capable of removing several drugs with tolerance to changes in concentration, which constitutes an economic and sustainable alternative that can be coupled to the treatment of wastewater contaminated with this type of compounds.
