摘　　要：全球可再生能源与环保关注度攀升,餐厨垃圾资源化利用凸显其重要性。厌氧消化技术因能将餐厨垃圾转化为甲烷而具潜力,但稳定性与低产率成为其发展瓶颈。大量研究发现,引入铁基导电材料(Iron-based Conductive Materials, ICMs)可显著提升厌氧消化效率与甲烷产量。本文深入探讨了ICMs对餐厨垃圾厌氧消化的促进作用,从微生物菌落结构、酶活性和直接种间电子传递等多个层面揭示了ICMs的作用机制。此外,对ICMs实际工程的应用前景进行了展望,旨在为餐厨垃圾厌氧消化工程中的ICMs应用提供理论支撑和参考。Globally,the heightened focus on renewable energy and environmental protection underscores the paramount importance of resource recovery from kitchen waste.Anaerobic digestion(AD)technology,with its capability to transform kitchen waste into methane,holds immense potential;however,its stability and relatively low productivity have emerged as key bottlenecks impeding further development.Extensive research endeavors have demonstrated that the incorporation of iron-based conductive materials(ICMs)can substantially enhance the efficiency of AD processes and methane yield.This study delves into the stimulatory effects of ICMs on AD of kitchen waste,elucidating their mechanisms of action through multifaceted analyses encompassing microbial community structures,enzymatic activities,and direct interspecies electron transfer(DIET).Furthermore,we provide a forward-looking perspective on the practical engineering applications of ICMs,aiming to furnish theoretical underpinnings and practical guidance for the integration of ICMs in kitchen waste AD projects.
