Abstract

Abstract:

Treating high salinity wastewater by using common methods like biochemical methods, evaporation and membrane treatment is difficult and costly. Microbial fuel cell (MFC) is a device for converting chemical energy into electrical energy using electricigens as the catalysts. Application of MFC in wastewater treatment could lower the treatment cost due to additional electricity generation during the wastewater treatment. In recent years, using MFC to treat high salinity wastewater for lowering the treatment cost has been tested and gradually become a hot spot. The aim of this paper is to review the latest research progress of MFC for treating high salinity wastewater. The effects of salinity on electricity generation, pollutant removal, growth and community of microorganisms of MFC were summarized. The future research works of MFC for high salinity wastewater treatment are proposed on salt-tolerant microorganisms, biofilm, the reactor structure and extended applications.

Key words: wastewater, high salinity, microbial fuel cell, degradation, bioenergy

摘要：

高盐废水通常采用生化、蒸发和膜处理3种方法处理，但无论采用何种方法，高盐废水处理均存在难度大和成本高等问题。微生物燃料电池（MFC）是一种基于产电微生物催化氧化有机物获得电能的装置，应用MFC处理废水可实现在处理废水的同时回收废水中能量，从而降低废水处理成本。近年来，应用MFC处理高盐废水来降低处理成本的研究逐渐开展并成为一个研究热点。本文综述了MFC处理高盐废水研究的最新进展，分析了盐度对MFC产电、污染物脱除、微生物生长和群落的影响，基于耐盐微生物、生物膜、反应器结构及扩展应用等方面提出未来MFC处理高盐废水的研究方向。
