铁碳微电解基质在人工湿地中的作用机理及研究现状

Iron-carbon micro-electrolysis substrate for constructed wetland:Interaction mechanisms,performance and Ecological effects

人工湿地是污水生态处理的有效手段之一,湿地基质作为人工湿地的主要成分,显著影响其处理效果.随着社会经济的发展,越来越多的污染物被排放至水体中.而传统基质对抗生素等新污染物的去除存在一定局限性,铁碳微电解基质可有效弥补其不足.本文全面综述了铁碳微电解材料在人工湿地中去除污染物的作用机理,总结了其对常规污染物与新污染物去除的研究现状.此外,本文还考察了铁碳微电解基质的生态效应,并对该领域未来的研究提出展望,以期为未来开展相关研究工作与工程应用提供一定的理论指导.

Constructed wetlands(CWs)are widely recognized as one of the cost-effective ecotechnologies for wastewater treatment.As a critical component in CWs,the substrate significantly influences the performance of CWs.Nowadays,rapid industrialization is producing a lot of emerging pollutants in water,which cannot be ignored.Traditional substrates struggle to handle emerging pollutants such as antibiotics.Iron-carbon micro-electrolysis(IC-ME)substrate can effectively make up for the deficiency.In this paper,the mechanism of IC-ME substrate for pollutant removal in constructed wetlands is comprehensively reviewed,and the research status of the removal of conventional pollutants and emerging pollutants is summarized.In addition,the ecological effects of IC-ME substrate are investigated.The future research in this field was prospected,aiming to provide a reference for further scientific research and engineering applications.
