The physical and chemical treatment processes of leachate are not only costly but can also possibly produce harmful by products. Constructed wetlands (CW) has been considered a promising alternative technology for leachate treatment due to less demand for energy, economic, ecological benefits, and simplicity of operations. Various trends and approaches for the application of CW for leachate treatment have been discussed in this review along with offering an informatics peek of the recent innovative developments in CW technology and its perspectives. In addition, coupling CW with microbial fuel cells (MFCs) has proven to produce renewable energy (electricity) while treating contaminants in leachate wastewaters (CW-MFC). The combination of CW-MFC is a promising bio electrochemical that plays symbiotic among plant microorganisms in the rhizosphere of an aquatic plant that convert sun electricity is transformed into bioelectricity with the aid of using the formation of radical secretions, as endogenous substrates, and microbial activity. Several researchers study and try to find out the application of CW-MFC for leachate treatment, along with this system and performance. Several key elements for the advancement of CW-MFC technology such as bioelectricity, reactor configurations, plant species, and electrode materials, has been comprehensively discussed and future research directions were suggested for further improving the performance. Overall, CW-MFC may offer an eco-friendly approach to protecting the aquatic environment and come with built-in advantages for visual appeal and animal habitats using natural materials such as gravel, soil, electroactive bacteria, and plants under controlled condition.
渗滤液的物理和化学处理过程不仅成本高昂，而且还可能产生有害副产品。人工湿地（CW）由于对能源的需求较少、具有经济和生态效益以及操作简单，已被视为一种有前景的渗滤液处理替代技术。本综述讨论了人工湿地用于渗滤液处理的各种趋势和方法，并对人工湿地技术的最新创新发展及其前景进行了信息透视。此外，事实证明，将人工湿地与微生物燃料电池（MFC）耦合在处理渗滤液废水（CW-MFC）中的污染物时可产生可再生能源（电力）。CW-MFC的组合是一种有前景的生物电化学系统，在水生植物根际的植物微生物之间发挥共生作用，利用自由基分泌物的形成作为内源性底物，并借助微生物活性将太阳能转化为生物电。几位研究人员研究并试图找出CW-MFC在渗滤液处理中的应用以及该系统和性能。本文全面讨论了推进CW-MFC技术的几个关键要素，如生物电、反应器配置、植物种类和电极材料，并提出了未来的研究方向以进一步提高性能。总体而言，CW-MFC可能提供一种环保方法来保护水生环境，并在可控条件下使用砾石、土壤、电活性细菌和植物等天然材料，具有视觉吸引力和动物栖息地等内在优势。
