【摘要】 为探究生物炭表面物理结构(比表面积、孔径和孔容)对市政污泥好氧发酵过程中硫化氢释放的影响，本研究选用不同结构特征的生物炭作为调理剂进行好氧发酵试验。结果表明，与对照组相比，添加榉木生物炭、玉米芯生物炭和稻壳生物炭处理组的硫化氢累积释放量分别减少了50.46%、12.92%和36.20%。根据高通量测序可知，榉木生物炭的小孔径结构可通过减少好氧发酵过程中硫还原菌Hydrogenispora的相对丰度来减少硫化氢的产生。冗余分析表明生物炭表面物理结构对H2S释放的影响主要取决于孔容，其次是比表面积和孔径。更多还原

【Abstract】 To investigate the effects of physical structure(specific surface area, pore diameter and pore volume) of biochar surface on hydrogen sulfide release during aerobic fermentation of municipal sludge, biochar with different structural characteristics was selected as conditioning agents for aerobic fermentation experiments in this study. The results showed that the cumulative release of hydrogen sulfide was reduced by 50.46 %, 12.92 % and 36.20 % in the groups treated with beech wood biochar, corncob biochar and rice husk biochar, respectively, compared with the control group. Based on high-throughput sequencing, it was shown that the small pore diameter structure of beech biochar could reduce hydrogen sulfide production by reducing the relative abundance of the sulfur-reducing bacterium Hydrogenispora in the aerobic fermentation process. Redundancy analysis showed that the effect of the physical structure of biochar surface on H2S release mainly depends on the pore volume, followed by specific surface area and the pore diameter.更多还原
