摘 要: 構(gòu)建雙室無膜折流板式微生物燃料電池,研究雙室無膜折流板微生物燃料電池的產(chǎn)電性能和廢水處理,在不需要外部電源的情況下,直接利用微生物燃料電池產(chǎn)生的電能處理陰極模擬含銅廢水并回收銅。結(jié)果表明:以乙酸鈉為陽極底物,以馴化后的活性污泥混合菌為陽極接種微生物,以Cu2+為陰極電子受體可成功啟動無膜折流板微生物燃料電池,最大功率密度為31.3 mW/m2,開路電壓最高為678.0 mV,Cu2+去除率為99.6%;經(jīng)XRD分析,陰極板上的沉積物主要為單質(zhì)銅,雙室無膜折流板微生物燃料電池可有效處理含銅廢水并回收銅。

Abstract:The baffled membraneless dual chamber microbial fuel cell (MFC) was constructed, the electricity generation capacity of baffled membraneless dual chamber MFC and wastewater treatment were studied, the electricity produced by MFC was used directly to treat cathode simulation copper-containing wastewater and recover copper. The results show that the baffled membraneless dual chamber MFC is started successfully in which sodium acetate is used as anode substrate, complex acclimated microorganism in activated sludge is used as anode inoculating microorganism, Cu2+ is used as cathodic electron acceptor, the maximum power density is 31.3 mW/m2 and the maximum open circuit voltage is 678.0 mV, the removal rate of Cu2+ is 99.6%, sediment on the cathode plate detected by XRD is mainly Cu. The baffled membraneless dual chamber MFC can effectively treat copper-containing wastewater and recover copper.
