沉积物微生物燃料电池的应用现状与展望

Application and Prospects of Sediment Microbial Fuel Cell

沉积物微生物燃料电池(SMECs)是一种典型的无膜微生物燃料电池,它借助于沉积物中具有电化学活性微生物的催化作用,氧化沉积物中有机物以获得电能。本文根据国内外SMFCs研究发展现状,探讨了SMFCs在为海洋或内陆水体的长期监测仪器提供低功率的电源、作为一种新型高效的沉积物原位生物修复技术以及作为毒性检测传感器等方面的应用现状,并讨论了其应用过程中存在的问题,最后对其今后的研究方向进行了展望。

Sediment electric energy from microbial fuel cells （SMFCs） are typical membrane-free microbial fuel cells and obtain organic-rich aquatic sediments by the catalysis of electrochemically active microorganisms. Based on the status of the research and development at home and abroad, this paper discusses the ap plication of SMFCs from three aspects：provision of low-power electrical energy,in-situ sediment bioremed iation and toxicity detection sensor. The results suggest that SMFCs can provide low-power for the instru ments of long-term monitoring in the ocean or inland water bodies and also can be used as a new and effi cient technology of in-situ sediment bioremediation. The paper analyzes the existing problems in the appli cation process and points out the potential directions of the application of SMFCs.
