摘要:
微生物燃料电池(Microbial Fuel Cell,MFC)中阳极电子传递过程是决定MFC产电量和产电速率的关键因素,优化微生物燃料电池阳极传递方式是提高MFC产电量的重要手段。以聚醚废水为实验基液,深红红螺菌397为MFC的催化剂,构建了阳极包裹型和阳极未包型两种MFC来研究其电子传递机制,结果显示,此微生物在阳极厌氧处理聚醚废水时通过直接接触机制和电子穿梭机制两种机制进来传递电子,直接接触机制的产电量是电子穿梭机制的1.79倍。此外还对如何提高MFC产电量进行了探讨,构建的AQDS型MFC优化了MFC的性能,MFC启动时间加快了4 h,最大输出电流提高了50%,产电量提高了39.5%。
Abstract:
The anodic electron transfer process in microbial fuel cell(MFC)is a key factor and the rate limiting step in determining the electricity producing quantity of MFC. Optimizing the transmission mechanism of anodic electron in microbial fuel cell is an important means to improve the electricity producing quantity of MFC. This study uses Rhodospirillum rubrum 397 to treat polyether wastewater, builds coated-MFC, Non-packet-MFC and AQDS-MFC to treat polyether wastewater, and conduct a study on its electronic transmission mechanism, In addition, this paper holds a discussion on how to improve the production of MFC. The results showed, Rhodospirillum rubrum 397 transfer electron in the anode chamber through direct contact mechanism and electronic shuttle mechanism. The direct contact mechanism contributes 1.79 times the contribution of the electronic shuttle mechanism. AQDS MFC optimizes MFC performance, the MFC start-up time accelerates 4h, the maximum output current increases by 50% and electricity production increases by 39.5%.
