Summary:为了进一步提高微生物燃料电池的运行性能，提高硝酸盐降解率及改善电能输出情况，以城镇污水处理厂二沉池污泥为接种源，硝酸钠为电子受体运行典型单室空气阴极微生物燃料电池(MFC)。以1g/L无水乙酸纳、50mmol/L嶙酸盐缓冲液为模拟废水成功启动MFC,运行稳定后，通过碳源、碳氮比（C/N)、硝酸盐浓度、温度4个因素来优化MFC运行性能。实验结果表明：在温度为30°C、无水乙酸钠为碳源、C/N=5:1、硝酸盐质量浓度为200mg/L时MFC运行性能最佳，硝酸盐去除率均可达到90%以上，最大电压可达到0.462V。最佳状态下经6个周期运行，MFC最高电压为0.62V，功率密度高达4.53W/m2;交流阻抗分析最佳运行状态下MFC内阻为130(1，扫描电镜观察到电极表面微生物种类及数量均明显增多。研究证明MFC可以作为含硝酸盐废水产能净化的有效技术。

In order to improve the operation performance of microbial fuel cells,improved the degradation rate of nitrate and the power output of microbial fuel cell, a typical single chamber air-cathode microbial fuel cell (AC-MFC) is inoculated and operated with urban sewage treatment plant clarifier sludge as inoculum source and sodium nitrate as electron acceptor. It is successfully started by synthetic wastewater containing a phosphate buffered nutrient solution (PBS, 50 mmol/L) and sodium acetate (1 g/L). After successful starting, the four factors of carbon source, C/N, nitrate concentration and temperature are considered to optimize the operation performance of MFC. The test result shows that the operation performance of MFC is best under the conditions of anhydrous sodium acetate as carbon source, C/N of 5 : 1, 200 mg/L nitrate concentration and at 30 °C , and the degradation rate
