A novel membrane‐less microbial fuel cell (ML‐MFC) which used the baffles instead of the ion exchange membrane (IEM) was developed for ammonium‐containing wastewater treatment and electricity generation. By means of installing an ideal nitrifying unit between the anodic and cathodic chamber, the novel ML‐MFC accomplished organics degradation and nitrogen removal without additional loop. The removal efficiencies of COD, NH₄⁺−N and TN achieved 97.07±0.47 %, 91.76±3.32 % and 87.66±1.59 %, respectively. Meanwhile, the effluent pH was near neutral and turbidity was quite low. In addition, the maximum power density of 1.007±0.032 W/m³ was obtained. Combined with the analysis of microbial community, electroactive bacteria (EAB) Desulfovibrio, Comamonas and Thiobacillus were enriched in biofilm. Considering the superior effluent quality and the promising energy potential, the novel ML‐MFC has good application prospects in efficient and sustainable wastewater treatment.

具有夹层硝化室的新型无膜微生物燃料电池（ML‐MFC）的开发，可有效处理废水

开发了一种新型的无隔板微生物燃料电池（ML‐MFC），该隔板使用挡板代替离子交换膜（IEM）来处理含铵废水和发电。通过在阳极室和阴极室之间安装理想的硝化单元，新型ML‐MFC可以完成有机物的降解和氮的去除，而无需附加回路。COD，NH ₄ ⁺ -N和TN的去除率分别达到97.07±0.47％，91.76±3.32％和87.66±1.59％。同时，废水的pH值接近中性，浊度很低。另外，获得了1.007±0.032W / m ³的最大功率密度。结合微生物群落分析，电活性细菌（EAB）脱硫弧菌，Comamonas和Thiobacillus富含生物膜。考虑到出众的废水质量和可观的能源潜力，新型ML‐MFC在高效，可持续的废水处理中具有良好的应用前景。
