摘要
厨余垃圾产量大、有机物含量高、营养元素丰富,对其进行适当处理后资源化利用是厨余垃圾处理的发展方向。厌氧消化可实现生物质能的高效利用,是厨余垃圾资源化、无害化处理的主要方法之一。提升餐厨垃圾厌氧消化效率获得清洁能源及对消化产物的综合利用是目前研究的热点。介绍了厨余垃圾的基本特性、厌氧消化的机理,总结厨余垃圾厌氧消化各阶段面临的问题,分析对应的国内外调控策略的优缺点及研究进展,并对今后厨余垃圾厌氧消化的调控新策略及产物再利用进行展望。
A large amount of food waste was produced with high content of organic matter and rich nutrient elements.Resource utilization after proper treatment is one of the potential methods for food waste disposal.Efficient utilization of the biomass energy in food waste could be realized by anaerobic digestion,thus it was the main technology for resource utilization and harmless treatment of food waste.The improvement of anaerobic digestion efficiency to gain clean energy and integrated utilization of digestion products was a research hotspot worldwide.The research progress of treatment and resource utilization of food waste was reviewed in this article,including the basic characteristics of food waste and the mechanism of anaerobic digestion,the problems in each stage of anaerobic digestion of food waste,and the advantages and disadvantages of strategies and research progress.The development direction of anaerobic digestion and products utilization was also proposed.
