  • 摘要: 以炼油废水为碳源,构建双室填料型微生物燃料电池,考察接种液、外接电阻等电池启动条件,以及电导率、pH值和缓冲溶液强度等溶液性质对电池产电性能的影响。利用微生物燃料处理炼油废水,COD去除率(52±4)%,含油量去除率(81.8±3)%;利用废水中存在的原生菌即可启动电池,但启动期长,外加接种液可快速启动电池;启动时外接电阻的大小对电池稳定运行后的输出功率有明显影响,对电池内阻影响相对较小,当启动外接电阻为2 000Ω,电池输出功率最大,为288 mW/m3;随阳极溶液电导率电池增大,电池内阻降低,输出功率升高;pH值变化对电池阳极电势影响较大,进而影响电池输出,当溶液pH为9时,电池输出电压最大(388 mV),pH过高或过低均不利于电池产电;随着缓冲强度的增大,电池输出电压增大,且PBS缓冲强度的增大可从电导率增大和改善质子传递条件两方面提高电池的输出功率。
    Abstract: A two-chambered packing type microbial fuel cell (MFC) with refinery wastewater as its fuel was constructed to study the influence of starting conditions which included inoculum, external resistance, and solution properties of conductivity, pH and PBS strength on electricity generation of MFC. After being treated by MFC, COD removal rate of refinery wastewater was (52±4)%, and that for oil was (81.8±3)%. Microorganisms existed in initial wastewater could start up MFC, but the start-up period was long, and inoculums were needed to start up MFC quickly. The influence of external resistance used at start-up period on power density was obvious, while its influence on internal resistance of MFC was relatively little, and power density of MFC was 288 mW/m3, highest of all, when start-up external resistance was 2 000 Ω. Power density increased and internal resistance decreased following with the increase of anolyte conductivity. The optimal performance of MFC was achieved when pH value was 9 (388 mV), and performance of MFC was worse at both lower and higher pH value. Power density increased with the increase of buffer intensity.
