  • 摘要: 以重庆市主城区的餐厨垃圾为研究对象,调查分析其组成成分及粒径、含水率、挥发性固体(VS)含量等理化性质,并通过半连续式单相厌氧消化试验,进一步研究餐厨垃圾在中温条件下37±2 ℃的产甲烷性能.结果表明,重庆市主城区餐厨垃圾的主要成分为食物残渣、厨余废物等易消化物质,并具有含水率、含油率和VS含量较高等特性;半连续式厌氧消化试验所得实际产甲烷潜能为0.363—0.713 L CH4·g-1 VS,占理论产甲烷潜能的45.77%—89.93%,稳定运行时VS去除率达到88.87%—93.85%.中温厌氧消化技术能有效地处理重庆市餐厨垃圾并同时从中高效地回收清洁能源沼气.
    Abstract: The basic physical and chemical properties of food waste collected from the urban areas of Chongqing were investigated in this study, including waste components, particle size distribution, moisture content (MC), and volatile solids (VS) content. Moreover, a semi-continuous single-phase anaerobic digestion reactor was initiated under mesophilic conditions 37±2 ℃ in an effort to make clear its performance on anaerobic digestion of food waste. The results revealed that easily biodegradable organics (including food residues and kitchen waste) were the major component of the food waste, characterized by high water content, high lipid content and high VS content. The experiment-based methane production potential in the single-phase anaerobic digestion reactor was 0.363—0.713 L CH4·g-1 VS, which was 45.77%—89.93% of the theoretically calculated values. And the removal efficiency of VS reached 88.87%—93.85% when the digestion reactor became stable. Based on these results, anaerobic digestion of food waste performed under mesophilic conditions is recommended as an effective technology for treatment of food waste and simultaneously recycling of clean energy.
