摘要：作者以组合式生物阴极微生物燃料电池(CB-MFC)处理高氨氮废水为研究对象，通过实验验证和数据分析，深入探讨了该工艺的处理效果。实验结果表明，CB-MFC在高氨氮废水处理中展现出了出色的性能。在长达30 d的实验周期内，氨氮去除率持续上升，并最终达到了99.67%。这一结果不仅证明了CB-MFC在处理高氨氮废水方面的有效性，也表明该工艺能够显著降低废水中的氨氮含量，使其符合甚至优于废水排放标准。CB-MFC的运行条件对氨氮去除率具有显著影响，通过布置格栅、优化pH值、废水生物处理，可以进一步提高系统的处理效率。

Abstract: This study focuses on the treatment of high ammonia nitrogen wastewater using a combined biocathode microbial fuel cell (CB-MFC). Through experimental verification and data analysis, the treatment effect is deeply explored. The experimental results indicate that CB-MFC has demonstrated excellent performance in the treatment of high ammonia nitrogen wastewater. During the 30-day experimental period, the ammonia nitrogen removal rate continued to increase and ultimately reached a high level of 99.67%. This result not only demonstrates the effectiveness of CB-MFC in treating high ammonia nitrogen wastewater, but also indicates that the process can significantly reduce the ammonia nitrogen content in wastewater, making it meet or even better than wastewater discharge standards. The operating conditions of CB-MFC have a significant impact on the ammonia nitrogen removal rate. By arranging grids, optimizing pH values, and biological treatment of wastewater, the treatment efficiency of the system can be further improved.
