摘要
在以碳纸为阳极、空气电极为阴极、葡萄糖和对硝基苯酚为混合燃料的直接空气阴极单室微生物燃料电池中,考察了微生物燃料电池(MFC)对对硝基苯酚的降解及MFC的产电特性。结果表明MFC对废水中不同浓度的对硝基苯酚均有一定的去除效果,400 mg/L的对硝基苯酚降解4d的去除率74.1%,降解6 d的去除率为82.1%。MFC的输出电压最高为0.293 V(外阻1 000Ω),最大输出功率密度为56.5 mW/m3。
The degradation of p-nitrophenol and electricity generation of MFC are studied in a single air-cathode microbial fuel cell which is constructed using air electrode as cathode and carbon paper as anode, with glucose and p-nitrophenol as the anode mixed fuels. Experimental results demonstrate that MFC has a certain effect of removing p-nitrophenol of different concentrations. The removal rate of 400 mg/L of p-nitrophenol can be 74.1% when reaction time is 4 days and the rate be 82.1% when reaction time is 6 days.The maximum output voltage of MFC is 0.293 V（ external resistance, 1 000Ω）and the maximum output power of MFC is 56.5 mW/m^3 （wastewater） .
