摘要:采用微生物燃料电池(Microbial fuelcell,MFC)处理模拟含硫废水,硫化物能全部被氧化成单质硫或硫酸盐。MFC的最大功率密度达到(20±1)W·m-3,库仑效率为(20±2)%。阳极中有机质的氧化与硫化物的氧化存在一定竞争关系,进水碳硫比是影响单质硫生成率的关键因素。试验中,进水碳硫质量比大于12.50:1,S2-质量浓度为50mg·L-1时,硫化物氧化成单质硫的转化率可达61%~77%。此外,阳极表面单质硫的积累很可能是造成MFC电极失效或运行不稳定的原因之一。
A microbial fuel cell(MFC)was used to treat sulfide-bearing wastewater,which showed that sulfide could be oxidized to elemental sulfur or sulfate in the anode.The MFC generated electricity with maximum power density of(20+1)W·m^-3 and coulombic yield of(20±2)%.C/S of influent played an important role in elemental sulfur production because of competition between acetate oxidation and element sulfur oxidation in anode.The elemental sulfur production rates of 61%-77%were achieved by sulfide oxidation when C/S was higher than 12.50:1 and sulfide concentration was 50 mg·L^-1.Accumulation of elemental sulfur on anodic electrode would be a possible reason resulting in electrodes invalidity and operational instability in MFC.
