In this study, the microbial fuel cell (MFC) was combined with the Fenton-like technology to simultaneously generate electricity and degrade refractory contaminants in both anode and cathode chambers. The maximum power density achieved was 15.9 W/m(3) at an initial pH of 3.0 in the MFC. In the anode chamber, approximately 100% of furfural and 96% COD were removed at the end of a cycle. In the cathode chamber, the Fenton-like reaction with FeVO(4) as a catalyst enhanced the removal of AO7 and COD. The removal rates of AO7 and COD reached 89% and 81%, respectively. The optimal pH value and FeVO(4) dosage toward degrading AO7 were about 3.0 and 0.8 g, respectively. Furthermore, a two-way catalyst mechanism of FeVO(4) and the contaminant degradation pathway in the MFC were explored.
在这项研究中，微生物燃料电池（MFC）与类芬顿技术相结合，同时在阳极室和阴极室中产生电能并降解难处理的污染物。在初始 pH 值为 3.0 的条件下，MFC 的最大功率密度达到 15.9 W/m(3)。在阳极室中，循环结束时呋喃甲醛和 COD 的去除率分别达到 100%和 96%。在阴极室中，使用 FeVO(4)作为催化剂的类芬顿反应增强了对 AO7 和 COD 的去除。AO7 和 COD 的去除率分别达到 89%和 81%。降解 AO7 的最佳 pH 值和 FeVO(4)用量约为 3.0 和 0.8 g。此外，还探索了 FeVO(4)的双效催化剂机制和 MFC 中污染物的降解途径。
