摘要
分别利用乙醇和硝酸盐作为生物电化学系统阳极碳源和阴极氧化剂,试验了生物电化学系统的脱氮产电性能,研究了温度、pH值和盐度对系统性能的影响。生物电化学系统稳定运行时最大电压达到295.3 mV,阳极COD和阴极硝酸盐去除率分别达到86.5%和91.3%。当温度为35℃,pH值=8,盐度为10 g/L时,生物电化学系统工作性能达到最优。
Ethanol and nitrate were respectively used as the anode carbon source and the cathode oxidant to test the denitrification and electricity generation performance of the bioelectrochemical system,and the effects of temperature,pH value and salinity on the performance of the system were studied.When the bioelectrochemical system run stably,the maximum voltage reaches 295.3 mV,and the removal efficiencies of the anode COD and cathode nitrate reach 86.5%and 91.3%.When the temperature,pH value and salinity were 35,8 and 10 g/L,the working performance of bioelectrochemical system reached the best.
