摘要
生物电化学系统(Bioelectrochemical System,BES)是一种新型污水处理技术,它以微生物作为催化剂,在处理污水的同时产生电能。通过硝化和生物电化学脱氮过程,在BES中去除和/或回收氮和磷。本文回顾了BES中营养物去除和回收的相关研究,讨论了BES在去除/回收氮和磷方面的影响因素和挑战,以期为BES中营养物去除和回收的进一步优化和发展提供参考。
Under the dual pressures of environmental pollution and resource shortage, conventional wastewater treatment processes with high energy consumption no longer meet the sustainable requirement. Bioelectrochemical systems （BES） can directly convert energy in wastewater to electricity with the micro- organism as catalyst as well as purify the wastewater. Nitrogen and phosphorus can be removed or recov- ered by nitrification and bioelectrochemical denitrification processes in BES. We reviewed the nutrients removal and recovery in a BES, discussed the influence factors and key challenges for nitrogen and phos- phorus removaL/recovery in a BES. It is expected to provide a reference for nutrient removal and recovery of BES in the further optimization and development.
