In recent years, human urine has been successfully used as an electrolyte and organic substrate in bioelectrochemical systems (BESs) mainly due of its unique properties. Urine contains organic compounds that can be utilised as a fuel for energy recovery in microbial fuel cells (MFCs) and it has high nutrient concentrations including nitrogen and phosphorous that can be concentrated and recovered in microbial electrosynthesis cells and microbial concentration cells. Moreover, human urine has high solution conductivity, which reduces the ohmic losses of these systems, improving BES output. This review describes the most recent advances in BESs utilising urine. Properties of neat human urine used in state-of-the-art MFCs are described from basic to pilot-scale and real implementation. Utilisation of urine in other bioelectrochemical systems for nutrient recovery is also discussed including proofs of concept to scale up systems.

生物电化学系统中的尿液:总体回顾。

近年来,人尿因其独特的性质已成功用作生物电化学系统(BES)中的电解质和有机底物。尿液中含有有机化合物,可用作微生物燃料电池(MFC)能量回收的燃料,并且具有高营养浓度,包括氮和磷,可以在微生物电合成电池和微生物浓缩池中浓缩和回收。此外,人尿具有高溶液电导率,这减少了这些系统的欧姆损耗,从而提高了 BES 输出。这篇综述描述了利用尿液的 BES 的最新进展。从基础到中试规模和实际实施,描述了最先进的 MFC 中使用的纯人类尿液的特性。还讨论了在其他生物电化学系统中利用尿液进行营养回收,包括扩大系统规模的概念验证。
