摘　　要：为了处理废水,介绍了微生物脱盐燃料电池和微生物电解电池的起源、原理并结合国内外研究对其各自在废水处理方面的应用。提出了一种无需外加电源辅助的新工艺—MDC-MEC耦合系统,结合以上二者的原理为此耦合系统运行提供一定理论基础,此系统能够结合微生物脱盐电池特性,利用MDC进行产电、脱氨及氨回收,并将MDC作为微生物电解电池的外加电源辅助制氢,也对其在国内外在废水处理方面的应用进行综述,最后对MDC-MEC耦合系统的性能优化进行了展望。To treat wastewater, the origins and principles of microbial desalination fuel cells and microbial electrolysis cells were introduced respectively, and their respective applications in wastewater treatment in the context of domestic and international research were reviewd. The above conclusions were combined to propose a new process without external power supply assistance MDC-MEC coupling system, combining the above two principles provides a theoretical basis for the operation of this coupled system. This system is capable of combining microbial desalination cell characteristics, power generation, deamination and ammonia recovery using MDC, and MDC is used as an external power source for microbial electrolysis cell to assist in hydrogen production, a review of its application in wastewater treatment in Japan and abroad is also presented, finally, the performance optimization of the coupled MDC-MEC system is envisioned.
