构建双室无膜折流板式微生物燃料电池,研究双室无膜折流板微生物燃料电池的产电性能和废水处理,在不需要外部电源的情况下,直接利用微生物燃料电池产生的电能处理阴极模拟含铜废水并回收铜.结果表明:以乙酸钠为阳极底物,以驯化后的活性污泥混合菌为阳极接种微生物,以Cu2+为阴极电子受体可成功启动无膜折流板微生物燃料电池,最大功率密度为31.3 mW/m2,开路电压最高为678.0 mV,Cu2+去除率为99.6%;经XRD分析,阴极板上的沉积物主要为单质铜,双室无膜折流板微生物燃料电池可有效处理含铜废水并回收铜.
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.
