摘　　要：为了探究耦合电化学系统对粪便黑水除碳脱氮的性能,将微生物燃料电池(MFC)和微生物电解池(MEC)反应器的耦合装置引入厌氧折板反应器(ABR)中,考察ABR/MFC/MEC反应器除碳脱氮的影响因素,并采用响应曲面法分析粪便黑水中COD和氨氮的去除率与水力停留时间(HRT)、进水COD浓度以及曝气量之间的关系。结果表明,当C/N值<30时,能快速达到同步除碳脱氮的效果,且最佳工况如下:水力停留时间为36 h、进水COD浓度为1 500 mg/L、曝气量为100 mL/min,COD和氨氮的预测值与实测值偏差率仅分别为0.094%和1.43%。The performance of nitrogen and carbon removal from fecal sewage in the coupling elec- trochemical system was studied by coupling microbial fuel cell （MFC） with microbial electrolysis cell （MEC） in the anaerobic baffled reactor. In the reactor integrated by ABR, MFC and MEC, factors influ- encing the nitrogen and carbon removal from fecal sewage was investigated and the relations between COD, ammonia nitrogen removal rate and hydraulic retention time, influent COD concentrations and aeration were analyzed by the response surface methodology. The results showed that when the C/N ratio was less than 30, the simultaneous carbon and nitrogen removal would be achieved rapidly. The optimum working condition was obtained according to the model calculation as follows ： HRT of 36 h, influent COD of 1 500 mg/L and aeration rate of 100 mL/min, when there were only 0. 094% and 1.43% relative er-ors between the predicted values and measured ones of COD and ammonia nitrogen respectively.
