| 摘 要： | 采用微生物燃料电池(Microbial fuel cell,MFC)处理模拟含硫废水,硫化物能全部被氧化戍单质硫或硫酸盐.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1250:1,S~(2-)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.

| Abstract: | A microbial fuel cell (MFC) was used to treat sujfide-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 tmd 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. |
