摘　　要：将具有氧化性的有机废水池作为电池的阳极,具有还原性的重金属废水池作为电池的阴极,利用微生物燃料电池(MFC)同时处理有机废水和重金属废水.结果表明,利用铜离子溶液作阴极,MFC最大电压可达到0.277 V,最大功率密度为33.49 mW/m2,COD的去除率为31.6%,铜的去除率可达42%;利用银离子溶液作阴极,MFC最大电压可达到0.311 V,最大功率密度为42.21 mW/m2,COD的去除率为64.6%,银的去除率可达78%.即不管是从产电角度还是从废水处理角度考虑,都是以银离子废水作阴极优于铜离子.Microbial fuel cell （ MFC） can be used to treat organic wastewater and heavy met-al wastewater simultaneously , with the oxidation of organic wastewater as anode , while with reduction of heavy metals waste water as cathode .The results showed that with copper ion solution as the cathode , the maximum voltage of MFC was up to 0.277 V, and the maximum power density reached to 33.49 mW/m2 .The removal rate of COD was 31.6%, and the re-moval rate of copper reached to 42%.With silver ion solution as the cathode , the maximum voltage of MFC was up to 0.311V.The maximum power density was 42.21 mW/m2 .The re-moval rate of COD and silver increased to 64 .6%and 78%, respectively .It was shown that copper ion was better than silver ion neither in the field of producing electricity nor the wastewater treatment .
