Abstract：
AbstractPharmaceutical compounds are a significant source of environmental pollution, particularly in hospital wastewater, which contains high concentrations of such compounds. Constructed wetlands have emerged as a promising approach to removing pharmaceutical compounds from wastewater. This paper aims to review the current state of knowledge on the removal of pharmaceutical compounds from hospital wastewater using constructed wetlands, including the mechanism of removal, removal efficiency, and future prospects. Pharmaceutical contaminants have been considered to be one of the most emerging pollutants in recent years. In this review article, various studies on constructed wetlands are incorporated in order to remove the pharmaceutical contaminants. The nature of constructed wetland can be explained by understanding the types of constructed wetland, characteristics of hospital wastewater, removal mechanism, and removal efficiency. The results of the review indicate that constructed wetlands are effective in removing pharmaceutical compounds from hospital wastewater. The removal mechanism of these compounds involves a combination of physical, chemical, and biological processes, including adsorption, degradation, and uptake by wetland plants. The removal efficiency of constructed wetlands varies depending on several factors, including the type and concentration of pharmaceutical compounds, the design of the wetland system, and the environmental conditions. Further research is necessary to optimize the performance of these systems, particularly in the removal of emerging contaminants, to ensure their effectiveness and long-term sustainability.
摘要：
药物化合物是环境污染的重要来源，特别是在医院废水中，其中含有高浓度的此类化合物。人工湿地已成为从废水中去除药物化合物的一种有前途的方法。本文旨在回顾有关使用人工湿地从医院废水中去除药物化合物的知识现状，包括去除机制，去除效率，和未来的前景。药物污染物被认为是近年来最新兴的污染物之一。在这篇评论文章中，为了去除药物污染物，对人工湿地进行了各种研究。人工湿地的性质可以通过理解人工湿地的类型来解释,医院废水的特点，去除机制，和去除效率。审查结果表明，人工湿地可有效去除医院废水中的药物化合物。这些化合物的去除机制涉及物理，化学,和生物过程，包括吸附，降解，和湿地植物的吸收。人工湿地的去除效率因几个因素而异，包括药物化合物的类型和浓度，湿地系统的设计，和环境条件。需要进一步的研究来优化这些系统的性能，特别是在去除新出现的污染物方面，确保其有效性和长期可持续性。
