摘　　要：采用双室的微生物燃料电池装置,探讨利用微生物燃料电池处理含铬废水的效率及电池性能。通过测定微生物燃料电池的电压、功率密度和电流密度,研究电池的性能,通过测定出水中Cr(Ⅵ)的浓度探讨微生物燃料电池对Cr(Ⅵ)的处理效率。结果表明,最大值出现在第21天,大约在18 mV左右;电压的最小值在0.5 mV左右,稳定值在2 mV左右;装置稳定后,在电流密度等于0.526μA/cm2时,电池的电压达到最大值,为39.5 mV;当电流密度为1.328μA/cm2,功率密度达到最大值,为1.328×10-3mW/cm2;利用微生物燃料电池装置对Cr(Ⅵ)可以达到一定的处理效果,去除率约为20%。A dual-chamber microbial fuel cell device was used to study the treatment of chromium-containing wastewater.Through the determination of the microbial fuel cell voltage,power density and current density,MFC performance was investigated.The treatment efficiency of chromium(VI) by microbial fuel cell was obtained through determining the concentration of hexavalent chromium in effluent.The results show that the maximum voltage is about 18 mV,the minimum voltage is about 0.5 mV,the stability voltage is about 2 mV;After the facility operation is stable,the maximum voltage is about 39.5 mV when current density is 0.526 μA/cm2;the maximum power density is about 1.328×10-3 mW/cm2 when current density is 1.328 μA/cm2.The microbial fuel cell for treating chromium(VI) is effective,and removal efficiency is about 20%.
