摘 要
随着全球水资源短缺和环境污染问题日益严重，传统废水处理技术面临高能耗与二次污染等挑战。基于此背景，本研究聚焦微生物燃料电池（MFC）在废水处理与能源回收中的应用，旨在开发一种高效、环保且可持续的污水处理新技术。通过构建新型双室MFC反应器，并引入纳米材料修饰电极以提升产电性能，实验采用实际印染废水作为底物，在优化运行参数条件下，考察了系统对有机污染物去除效率及电力输出特性。结果表明，该装置可实现化学需氧量（COD）去除率超过90%，同时稳定产生0.5 - 0.7V电压，最大功率密度达到1200mW/m²。创新性地将生物处理与物理化学过程耦合，不仅提高了污染物降解效果，还实现了能量的有效转化与回收。

Abstract
With the increasing shortage of water resources and environmental pollution, traditional wastewater treatment technology faces challenges such as high energy consumption and secondary pollution. In this background, this study focuses on the application of microbial fuel cell (MFC) in wastewater treatment and energy recovery, aiming to develop a new efficient, environmentally friendly and sustainable sewage treatment technology. By constructing a new two-chamber MFC reactor and introducing nanomaterials to modify the electrode to improve the electric production performance, the actual printing and dyeing wastewater was used as the substrate, and the removal efficiency and power output characteristics of the system were investigated under the condition of optimized operation parameters. The results show that the device can achieve the chemical oxygen demand (COD) removal rate over 90%, and stabilize the voltage of 0.5-0.7V, and the maximum power density reaches 1200 mW / m². Innovative coupling of biological treatment and physicochemical processes not only improves the degradation effect of pollutants, but also realizes the effective conversion and recovery of energy.
