摘　　要：在氧化沟中构建了微生物燃料电池,经测定微生物燃料电池电压为0.24～0.39 V,均值为0.29 V。经计算该微生物燃料电池的产电功率为0.05～0.15 mW,均值为0.08 mW。构建了微生物燃料电池的氧化沟COD去除率为75%～90%,TN去除率为5%～38%;无微生物燃料电池的氧化沟COD去除率为77%～89%,TN去除率为5%～23%。构建微生物燃料电池后能减少氧化沟内外沟中污泥的增加量,约减少15%。A microbial fuel cell（MFC） was constructed in the oxidation ditch.The determination results show that the voltage produced by the MFC is 0.24-0.39 V with the mean value of 0.29 V.According to calculation results,the power produced by the MFC is 0.05-0.15 mW with the mean value of 0.08 mW.The removal rates of COD and TN in the oxidation ditch with MFC are 75%-95% and 5%-38% respectively,while those in the oxidation ditch without MFC are 77%-89% and 5%-23% respectively.Additionally,the construction of MFC in the oxidation ditch can reduce the increase of sludge in the internal and external ditch by 15%.
