摘　　要：微生物脱盐电池是根据生物电化学系统衍生而来,基于产电微生物催化氧化有机物获得电能,驱动系统脱盐室中的离子迁移,达到脱盐目的以及形成增值副产物。如果采用废水作为有机质来源,微生物脱盐电池可同时实现盐水脱盐、能源生产和废水处理,是一种极具吸引力的环保技术。然而,维持阳/阴极室pH值、较高的内阻、电极催化剂、膜污染以及耐久性等仍是限制微生物脱盐电池实际应用的技术问题。本文综述了近年来微生物脱盐电池构造设计方面的研究进展,重点介绍了新型结构和运行控制对脱盐和产电性能的影响,为微生物脱盐电池技术的可持续发展及规模化提供新的思路。Microbial desalination cell(MDC)is derived from the bioelectrochemical system,which is based on the catalytic oxidation of organic matter by electrogenic microorganism to obtain electric energy.The electrical potential can then be used for water desalination by driving ion transport as well as formation of value-added by-products.If wastewater is used as the source of the organic matter,the MDC technology has been proven to be one of the emerging technologies capable of simultaneous seawater desalination,energy production and wastewater treatment.The technical challenges associated with their practical applications are maintaining the pH in cathodic and anodic fluids,higher internal resistance,usage of catalysts on electrodes,and membrane fouling and durability.The review summarizes the recently investigated MDC configurations along with their critical evolution of designs and operational parameters on the desalination and power generation capabilities,providing ideas for the sustainable development of MDC technology and its scale-up.
