摘要 通过优化阴极材料,构建新型单室无膜壁式空气阴极微生物燃料电池,开展了污泥浓度、阳极面积、导线材料和NaCl离子浓度等影响因素及其优化试验研究。结果显示:在恒温30℃和外接电阻1 000Ω的条件下,以铜线为导线,污泥浓度为21 000 mg/L,阳极面积为31.4 cm2,Na+浓度为200 mmol/L时,其产电性能最佳,最大电压为597 mV,最大输出功率密度为301 mW/m2,内阻为92.5Ω。此外,还分析了污泥运行过程中的变化。与目前其他以未经过预处理的剩余污泥作为底物的微生物燃料电池相比,该新型单室无膜壁式空气阴极微生物燃料电池功率密度较高,内阻较低。 Based on the previous studies, this experiment presented a new kind of microbial fuel cells (MFC), single--chamber air cathode microbial fuel cells without proton membrane. After investigating the influencing factors and optimizing the parameters such as sludge concentration, anode area, conductor and NaCl concentration, it was found that under the conditions of the constant temperature 30 ℃,external resistance 1 000 O,copper wire as conductor,sludge concentration 21 000 mg/L,anode area 31.4 cm2 and Na+ concentration 200 mmol/L, a better production performance with the maximum voltage of 597 mV, the maximum output power density of 301 mW/m2 and the internal resistance of 92.5 Ω was achieved. Also the changes of sludge in this process were analyzed. Compared with the recent MFC with untreated excess sludge as substrate, the electricity production performance of MFC in this experiment shows higher power density and lower internal resistance.
