【摘要】 厌氧共消化是市政有机固废减量化资源化的主流工艺之一，然而湖北省武汉市仍缺乏具有本地代表性的厨余垃圾与剩余污泥厌氧共消化效能及潜在影响的相关研究。通过生化产甲烷潜力批式实验、动力学分析和共消化性能评估考察了武汉本地典型厨余垃圾和剩余污泥的比例对厌氧共消化效能和潜在应用的影响。研究结果表明：厨余垃圾与剩余污泥共消化的产甲烷速率比厨余垃圾单独消化提高了40%～96%;厨余垃圾与剩余污泥的最佳比例为2∶1（基于VS）,此时实际产甲烷潜力为408 mLCH₄·g^-1VS_added,比理论叠加值提高了11.2%;厌氧消化的渗透率达到60%时，武汉本地的厨余垃圾和剩余污泥通过厌氧消化回收的能量高达6100万m³CH₄·a^-1或2亿kWh·a^-1,可以供应约7.6%的居民生活天然气需求量或1.7%的电力需求量，可为武汉本地乃至全国的厨余垃圾和剩余污泥共消化提供参考和指导意义。更多还原

【Abstract】 Anaerobic co-digestion（AcoD） is one of the optimal processes for volume reduction and resource recovery of organic fraction of municipal solid waste, but relevant studies on the anaerobic co-digestion of adequately representative food waste（FW） and waste activated sludge（WAS） are rare. In this study, the effects of ratios of typical local FW and WAS on AcoD performance and potential implications in Wuhan were investigated via biochemical methane potential batch tests, kinetic analysis, and implications discussion. The results showed that the co-digestion of FW and WAS increased the methane production rate by 40%～96% compared to FW mono-digestion. The optimal ratio of FW∶WAS was 2∶1（based on VS）, and the methane potential was 408 mL CH₄·g^-1VS_added, 11.2% higher than the theoretical stacked value. When the anaerobic digestion penetration rate reached 60%, the annual energy recovery of FW and WAS in Wuhan was 61 million m³ CH₄ or 200 million kWh·a^-1, which could supply about 7.6% of the residential natural gas demand or 1.7% of the electricity demand. This study could provide guidance and reference significance for the co-digestion of FW and WAS in Wuhan and even nationwide.更多还原
