摘要:采用人工湿地型微生物燃料电池处理啤酒生产废水，考察了啤酒生产废水中不同COD浓度条件下(475、1 968、5 640 mg·L-1)人工湿地型微生物燃料电池对COD和氨氮的去除效果，评估了在此过程中微生物燃料电池的产电性能。研究表明，当COD浓度为1 968 mg·L-1时，人工湿地型微生物燃料电池对COD的去除率最高，达到93.5%; 氨氮去除率随COD起始的增加而增加，当进水浓度为5 640 mg·L-1时，氨氮去除率达到70.8%。对产电性能而言，当进水COD浓度为1 968 mg·L-1时，人工湿地型微生物燃料电池产电量最高，其最大电压、功率密度和电流密度分别达到280 mV、24.2 mW·m-2和220 mA·m-2。利用人工湿地型微生物燃料电池处理啤酒生产废水具有一定的可行性，在处理污染物的同时产电，弥补了处理过程中的能源消耗，对废物资源化具有很好的应用前景。

Abstract:The constructed wetland microbial fuel cell (CW-MFC) was adopted in this study to treat brewery wastewater. The COD and ammonium removal efficiencies of CW-MFC, as well as power generation of MFC were investigated under different initial COD (475, 1 968, 5 640 mg·L-1) of brewery wastewater. The results indicated that the COD removal efficiency of CW-MFC reached the highest value of 93.5% at the initial COD of 1 968 mg·L-1. Ammonium removal efficiency increased with the increase of initial COD, and could reach 70.8% when the initial COD was 5 640 mg·L-1. The highest electricity production occurred at the initial COD of 1 968 mg·L-1, and the maximum voltage, power density and current density were 280 mV, 24.2 mW·m-2 and 220 mA·m-2, respectively. In all, it is feasible to use CW-MFC to treat brewery wastewater, and power is simultaneously generated, which can offset energy consumption during treatment and will present a good prospect for waste resource utilization.
