A priority target control list, which included hydrogen sulfide, ethyl mercaptan, methyl sulfide, and dimethyl disulfide, was confirmed in terms of the threshold dilution multiple (TDM). The results demonstrated that the TDM of hydrogen sulfide (H₂S) reached 2.49 $\times$ 10⁶, followed by ethyl mercaptan at 1.58 $\times$ 10⁴, methyl sulfide at 16.2, and dimethyl disulfide at 2.65. In addition, a series of response surface methodology tests were also undertaken to predict the effect of activated carbon (AC) on the control of emitted malodors studied and the optimal conditions for control. Herein, straw activated carbon (SAC), coal-based activated carbon (CAC), and nut shell activated carbon (NSAC) were chosen as the model types and supplemented to the anaerobic tank. The results indicated that AC is most effective when introduced as NSAC at 30% TS${}_{\mathrm{added}}$ (TS = total solids), with a particle size of over 2 mm. In addition, the emitted gas fluxes followed an increasing trend at much lower concentration at day 0, followed by peaking at day 5. Importantly, the result of the microbial community further demonstrated that the addition of AC gives rise to the enrichment of Bacteroides sp., regardless of AC type. Similarity, the phenomenon that Bacteroides sp., Clostridium sp., related to the anaerobic digestion process also increased after the AC feed compared to the control batch at genes level was also observed. Moreover, other microbes such as Spirochaetae sp., and Synergistetes sp., were also increased in the AC batch group. This study provides a new sight to control the odorous gases emitted from anaerobic digestion of food waste compared to the traditional chemical and/or simple adsorption and it would contribute to evaluation the influence of activated carbon to the microbial community.

根据阈值稀释倍数（TDM）确定了优先目标控制列表，其中包括硫化氢，乙硫醇，甲基硫和二甲基二硫。结果表明，硫化氢（H ₂ S）的TDM达到2.49 $\times$ 10 ⁶，然后是硫醇1.58 $\times$ 10 ⁴，甲基硫化物为16.2，二甲基二硫化物为2.65。此外，还进行了一系列响应表面方法学测试，以预测活性炭（AC）对所研究的恶臭排放控制的影响以及最佳的控制条件。在此，选择秸秆活性炭（SAC），煤基活性炭（CAC）和坚果壳活性炭（NSAC）作为模型类型并补充到厌氧罐中。结果表明，以30％TS的NSAC形式引入AC时最有效${}_{\mathrm{添加}}$（TS =总固体），粒度超过2毫米。此外，在第0天浓度低得多时，排放的气体通量呈上升趋势，然后在第5天达到峰值。重要的是，微生物群落的结果进一步表明，添加AC导致了拟杆菌的富集。 ，无论AC类型。相似地，在基因水平上，与对照批次相比，在交流进料后，与厌氧消化过程有关的拟杆菌属，梭菌属（Clostridium sp。）也增加了。此外，其他微生物如Spirochaetae sp。和Synergistetes在AC批处理组中也有所增加。与传统的化学和/或简单吸附相比，该研究为控制食物垃圾厌氧消化所释放的有毒气体提供了新的视野，并将有助于评估活性炭对微生物群落的影响。
