利用微生物燃料电池（MFC）以牛粪为燃料进行发电。由于MFC利用粪肥作为燃料的方式和粪肥-MFC的长期运行稳定性尚不清楚，本研究在171天的测试中检查了阳极室中溶解有机物（DOM）的演变和MFC的发电。所测试的MFC可以在整个测试期间通过单次进料粪便产生电力，在30-140天期间具有稳定的功率输出和总化学需氧量（TCOD）去除率。粪便的疏水性酸（HPO-A）和亲水性（HPI）组分是阳极液DOM的主要成分，两者的浓度在MFC操作中降低。可降解有机物转化为高芳香性化合物。
Microbial fuel cell (MFC) is applied to produce electricity using dairy manure as a fuel. Since the way MFC utilizes manure as a fuel and the long-term operation stability of manure-MFC remains unclear, this study examined the evolution of dissolved organic matter (DOM) in anodic chamber and power generation by MFC in a 171 days test. The tested MFC can produce electricity over the entire testing period by single feed of manure, with stable power output and total chemical oxygen demand (TCOD) removal rate in the period of day 30–140. The hydrophobic acid (HPO-A) and hydrophilic (HPI) fractions of manure were the principal components of anolyte DOM, with the concentrations of both being reduced over MFC operation. The degradable organic matters were converted to compounds with high aromaticity.
