Over half of century, sanitary landfill was and is still the most economical treatment strategy for solid waste disposal, but the environmental risks associated with the leachate have brought attention of scientists for its proper treatment to avoid surface and ground water deterioration. Most of the treatment technologies are energy-negative and cost intensive processes, which are unable to meet current environmental regulations. There are continuous demands of alternatives concomitant with positive energy and high effluent quality. Microbial fuel cells (MFCs) were launched in the last two decades as a potential treatment technology with bioelectricity generation accompanied with simultaneous carbon and nutrient removal. This study reviews capability and mechanisms of carbon, nitrogen and phosphorous removal from landfill leachate through MFC technology, as well as summarizes and discusses the recent advances of standalone and hybrid MFCs performances in landfill leachate (LFL) treatment. Recent improvements and synergetic effect of hybrid MFC technology upon the increasing of power densities, organic and nutrient removal, and future challenges were discussed in details.
半个多世纪以来，卫生填埋一直是（并且仍然是）固体废物处置最经济的处理策略，但渗滤液带来的环境风险引起了科学家们的关注，需要对其进行适当处理，以避免地表水和地下水恶化。大多数处理技术都是能源负增长且成本高昂的过程，无法满足当前的环境法规。人们不断需要替代品，同时要求有积极的能源和高的出水质量。在过去的二十年中，微生物燃料电池（MFC）作为一种具有生物电能产生的潜在处理技术问世，同时还可以进行碳和养分的去除。本研究综述了通过 MFC 技术从垃圾渗滤液中去除碳、氮和磷的能力和机制，以及总结和讨论了独立式和混合式 MFC 在垃圾渗滤液（LFL）处理方面的最新进展。详细讨论了混合式 MFC 技术在提高功率密度、有机物和养分去除方面的最新改进和协同作用，以及未来的挑战。
