| 摘 要： | 以焦化废水和乙酸钠为底物,构建单室微生物燃料电池(MFC),考察了乙酸钠对焦化废水中污染物去除及MFC产电性能的影响。结果表明,随着焦化废水中乙酸钠的质量分数从0增加到100%(相应COD从1 300 mg/L减小到0),MFC最大输出电压从61 mV增加到410 mV,最大功率密度从0.018 6 mW/m^2提高到0.420 1 W/m^2,废水中COD去除率从60%升高到95%。显然,外加乙酸钠提高了MFC中微生物的活性,使体系能够在稳定输出电能的同时强化焦化废水有机污染物的降解。

| Abstract: | The coking wastewater and sodium acetate as fuel,a single chamber microbial fuel cells(MFC)was constructed to investigated the effects of sodium acetate addition on pollutant removal from coking wastewater and the electrical generation of MFC.Results showed that,the COD of coking wastewater decreasing from 1 300 mg/L to 0 mg/L when the mass fraction of sodium acetate increased from 0 to 100%,the maximum output voltage of MFC increased from 61 mV to 410 mV,and maximum power density increased from 0.018 6 mW/m^2 to 0.420 1 W/m^2,and COD removal rate in waste-water increased from 60% to 95%.It is clear that sodium acetate will improve the activity of microorganisms of MFC,and make the system to enhance the degradation of organic pollutants from coking wastewater while stabilizing the power output. |
