摘　　要：总结了不同类型生物炭包括热解炭、水热炭以及改性生物炭对厌氧消化过程的影响,探讨了生物炭促进厌氧消化过程的机理。生物炭主要通过促进微生物种间互营关系、增强体系缓冲能力以及吸附抑制性物质来促进厌氧消化工艺性能。同时分析了生物炭对厌氧消化过程中微生物群落的影响,生物炭通过介导微生物种间直接电子传递,促进微生物间互营关系,进而影响消化过程稳定性及产甲烷效率。最后对生物炭材料促进厌氧消化过程的研究进行了展望。In this paper,the studies on the influences of different biochar types,including pyrolytic biochar,hydrochar and modified biochar,on anaerobic digestion were summarized.Mechanisms of enhancement of anaerobic digestion by biochar were discussed.Biochar enhanced anaerobic digestion process performance by promoting the syntrophic interaction of microorganisms,enhancing the system buffering capacity and adsorbing inhibitors.Besides,the effects of biochar on the microbial community during anaerobic digestion were also analyzed.Biochar are capable for promoting the syntrophic interaction of microorganisms by inducing direct interspecies electron transfer,thereby affecting process stability and methanogenic efficiency.Finally,future work on promoting organic waste anaerobic digestion with biochar was prospected.
