| 为探究腐熟堆肥不同回流方式对猪粪堆肥含硫臭气排放的影响，本文以猪粪为研究对象进行好氧堆肥试验，设置不添加腐熟堆肥（CK）、腐熟堆肥覆盖处理（Cap）和腐熟堆肥混匀添加（Mix）3个处理。研究结果表明：腐熟堆肥覆盖和混匀回流方式相较于CK均可促进堆肥腐熟，种子发芽指数（GI）分别提高12.50%和18.09%；甲硫醚（Me2S）和二甲基二硫醚（Me2SS）为猪粪高温堆肥过程中主要的含硫臭气（>90%），主要在堆肥前期和翻堆后排放。腐熟堆肥覆盖和混匀回流处理可分别减排Me2S 75.42%和78.64%、Me2SS 35.58%和56.17%，降低39.42%和58.31%的总含硫气体排放，增加堆肥产品总硫（TS）含量13.46%和24.07%。腐熟堆肥覆盖和混匀两种回流方式均可促进堆肥腐熟，减少含硫臭气排放，且腐熟堆肥混匀处理效果最佳。 |

| To explore the effects of different mature compost reflux methods on the emission of sulfur odors during composting, the covering and mixing methods of mature compost were designed, and the control treatment had no mature compost. The results showed that inoculating with mature compost increased the maturity of the final compost, and the seed germination index(GI)increased by 12.50% and 18.09%, respectively. Dimethyl sulfide(Me2S)and methyl disulfide(Me2SS)were the primary(> 90%)sulfur compounds released during composting, which were mainly emitted in the early stages of composting and after compost turning. The covering method and the mixing of mature compost method reduced Me2S emissions by 75.42% and 78.64%, respectively, and decreased Me2SS emissions by 35.58% and 56.17%, respectively. Subsequently, the reflux of mature compost reduced total sulfur odor emission by 39.42%~58.31%, and increased total sulfur(TS)content by 13.46%~24.07%, respectively. Generally, the addition of mature compost promote the maturity of compost and reduced sulfur-containing odor emissions and the mixing method showes the best performance. |
