Abstract:

在双室微生物燃料电池(MFC)阳极内接种反硝化细菌富集培养物,同时加入硝酸盐和甲醇,构建了阳极反硝化微生物燃料电池(AD-MFC),并以批式操作研究了AD-MFC的反硝化产电性能。试验结果表明,在初始硝氮浓度为(100.22±0.62)mg·L-1,COD浓度为(500.40±1.67)mg·L-1的条件下,AD-MFC的最大容积NO3--N和COD去除速率分别达到0.31kgN·m-3·d-1和1.06kgCOD·m-3·d-1,最大电压达到(602.80±5.42)mV,相应最大功率密度为(908.42±0.07)mW·m-3。AD-MFC的产电过程是甲醇氧化与硝酸盐还原的偶合过程,电压变化与反硝化作用密切相关,可用于指示反硝化进程。AD-MFC的电压曲线呈现降低-升高-再降低的三阶段特性,其原因是反硝化作用、甲醇降解作用和细胞水解发酵作用依次成为阳极液中的主导反应。
