Nutrient removal and recovery has received less attention during the development of bioelectrochemical systems (BES) for energy efficient wastewater treatment, but it is a critical issue for sustainable wastewater treatment. Both nitrogen and phosphorus can be removed and/or recovered in a BES through involving biological processes such as nitrification and bioelectrochemical denitrification, the NH4(+)/NH3 couple affected by the electrolyte pH, or precipitating phosphorus compounds in the high-pH zone adjacent a cathode electrode. This paper has reviewed the nutrients removal and recovery in various BES including microbial fuel cells and microbial electrolysis cells, discussed the influence factors and potential problems, and identified the key challenges for nitrogen and phosphorus removal/recovery in a BES. It expects to give an informative overview of the current development, and to encourage more thinking and investigation towards further development of efficient processes for nutrient removal and recovery in a BES.
在开发用于节能废水处理的生物电化学系统 (BES) 期间，养分去除和回收受到的关注较少，但这是可持续废水处理的关键问题。氮和磷都可以通过涉及生物过程（例如硝化和生物电化学反硝化）在 BES 中去除和/或回收，NH4(+)/NH3 偶联受电解质 pH 的影响，或者在阴极电极附近的高 pH 区沉淀磷化合物。本文综述了各种 BES 中的养分去除和回收，包括微生物燃料电池和微生物电解池，讨论了影响因素和潜在问题，并确定了 BES 中氮和磷去除/回收的关键挑战。它希望提供当前发展的信息概述，并鼓励更多地思考和研究，以进一步开发 BES 中养分去除和回收的高效工艺。
