Abstract

Abstract:

The conventional microbial electrolysis cells(MECs) research mainly focused on hydrogen production. With the rapid development,integrating energy generation,pollution control,and many kinds of application forms,MECs provide a new approach to solve the world wide problems of energy shortage and water resources protection. Therefore,MECs had drawn extensive attention of scientists all over the world. This paper mainly expounded three aspects of MECs researches:the principle, influence factors and applications. And MECs application perspectives, such as wastewater treatment,microbial electrosynthesis and integrated application, are also discussed in this paper. New MECs applications and reactor configurations were recently developed,benefitting from the new materials and new methods introduced into this research field. However,low concentration product enrichment,functional bacteria domestication for target pollutants,and the operation mechanism of MECs should be further studied to improve the overall performance and advance practical applications in water treatment and chemical production.

Key words: microbial electrolysis cell, desalination, wastewater treatment, microbial electrosynthesis, integrated application

摘要：

微生物电解池（microbial electrolysis cells，MECs）的研究方向主要集中于制氢，随着研究的深入，MECs发展出集产能与治污于一体以及多种应用形式，为解决当前国际面临的能源问题和水资源保护提供了一种新的解决方案，受到各国科学家的广泛关注。本文整理了MECs的原理、性能影响因素，重点介绍了MECs在水处理、微生物电合成产品和与技术集成三方面的国内外应用研究。分析显示：随着新材料和新方法引入本领域，MECs发展出现了许多新应用及与其相适应的反应系统构型，但仍需要在MECs应用潜力拓展、MECs产品低浓度条件下富集、功能菌对应目标污染物驯化、反应系统运行机制等方面作深入研究，以提高MECs的整体性能，推进MECs在水处理和生产化学品方面的实际应用。
