| 摘要:研究了微生物燃料电池处理OCC制浆废水及同步产电性能，为全面了解实验室研究与实际应用之间的差距，选用自制的和纸厂的两种OCC制浆废水进行比较分析。研究结果表明，阳极室进水为纸厂废水的反应体系在有机物去除及产电方面优于自制废水体系，反应器运行结束时自制废水和纸厂废水的CODCr去除率分别为81.3%和89.5%；自制废水体系于3个产电平台产生的输出电压分别低于纸厂废水体系，进水CODCr浓度为1000 mg/L时，两个体系得到的最大功率密度分别为289.9 mW/m2和303.0 mW/m2。通过扫描电子显微镜和傅里叶红外光谱分析可知，自制废水体系和纸厂废水体系中阳极优势菌群的表面形态不同，且红外谱图在吸收峰的数量及特定峰的强度上存在差异。 |
| Abstract:The OCC wastewater treatment and power generation using a micribial fuel cell were studied. In order to understand the difference between laboratory research and practical application, OCC wastewater prepared in lab and from paper mill was used. The results indicated that the system of mill wastewater was better than that of self made wastewater in organic matter removal and power generation. At the end of reaction, the removal rates of organic matter were 81.3% and 89.5% respectively. In the three platforms of power generation, the output voltage generated by self-made wastewater system was lower than that by mill wastewater system. When the CODCr concentration of influent was 1000 mg/L, the maximum power densities produced by the two systems were 289.9 mW/m2 and 303.0 mW/m2 respectively. The analysis of scanning electron microscopy and fourier transform infrared spectroscopy showed that the surface morphology of anode dominant bacteria in self made wastewater system was different from that in paper mill wastewater system. In addition, the two spectra were different in the number of absorption peaks and the intensity of specific peaks. |
