Microbial fuel cell (MFC) is a green innovative technology that can be employed for nutrient removal/recovery as well as for energy production from wastewater. This paper summarizes the recent advances in the use of MFCs for nutrient removal/recovery. Different configurations of MFCs used for nutrient removal are first described. Different types of nutrient removal/recovery mechanisms such as precipitation, biological uptake by microalgae, nitrification, denitrification and ammonia stripping occurring in MFCs are discussed. Recovery of nutrients as struvite or cattiite by precipitation, as microalgal biomass and as ammonium salts are common. This review shows that while higher nutrient removal/recovery is possible with MFCs and their modifications compared to other techniques as indicated by many laboratory studies, field-scale studies and optimization of operational parameters are needed to develop efficient MFCs for nutrient removal and recovery and electricity generation from different types of wastewaters.
微生物燃料电池 (MFC) 是一种绿色创新技术，可用于从废水中去除/回收营养物质以及生产能源。本文总结了 MFC 在去除/回收营养物质方面的最新进展。首先描述了用于去除营养物质的 MFC 的不同配置。讨论了 MFC 中发生的不同类型的营养物质去除/回收机制，例如沉淀、微藻的生物吸收、硝化、反硝化和氨汽提。通过沉淀、微藻生物质和铵盐回收营养物质是常见的。本综述表明，尽管与其他技术相比，MFC 及其改进可以实现更高的营养物质去除/回收，但是需要进行现场研究和优化操作参数，以开发用于从不同类型废水中去除和回收营养物质以及发电的高效 MFC。
