摘要:
为探索纳米三氧化二铁(Fe2O3 NPs) 和接种比(Inoculum to substrateratio, ISR) 对餐厨垃圾厌氧消化性能和微生物群落结构特性的影响机制 ,在 ISR为 1∶2、1∶1和2∶1条件下 ,分别添加质量浓度 1.0g/LFe2O3 NPs,开展中温批次厌氧消化产沼气实验 。结果表明 :不同 ISR条件下 Fe2O3 NPs对餐厨垃圾产气性能的影响差异显著 ,且不同程度地缓解了挥发性脂肪酸和氨氮的累积问题 , 当 ISR为 1∶2时 ,添加 Fe2O3 NPs显著提升了累积比甲烷产量 ,较对照组提高了 8.5%;ISR为 1∶1时 ,添加 Fe2O3 NPs对产气性能无显著影响;ISR为 2∶1时 ,添加 Fe2O3 NPs抑制产气 。微生物群落结构中 ,Firmicutes、Bacteroidota和 Synergistota是优势细菌门 ,Methanosaeta、Methanosarcina和Methanobacterium 是优势产甲烷古菌属 , 当 ISR为 1∶2时 ,Fe2O3 NPs显著提高了 Bacteroidota和Methanosarcina的相对丰度;ISR为 1∶1时 ,Fe2O3 NPs仅显著提高了 Methanosarcina的相对丰度;ISR为 2∶1时 ,Fe2O3 NPs则显著降低了Methanosaeta和Methanobacterium的相对丰度 。该文为了解 Fe2O3 NPs及接种比对餐厨垃圾厌氧消化特性的影响提供试验支撑 ,进而为沼气工程的规模化应用和稳定运行提供理论参考。
