城市生活垃圾厌氧消化技术研究进展

Research Progress on Anaerobic Digestion Technology of Municipal Solid Waste

随着全球经济快速发展以及居民生活水平的提高,城市生活垃圾的产量日益增加,垃圾处理己成为限制城市化进程和城市经济发展的重大问题之一.本文综述了城市生活垃圾的物理组成分类以及特性和成分分析,总结讨论了目前生活垃圾主要的厌氧消化技术进展,并对城市生活垃圾厌氧消化技术中干/湿厌氧消化、单相/两相厌氧消化、连续/批式厌氧消化、常/高温厌氧消化等工艺进行了详细说明,以及阐述有机负荷、pH值温度等因素对厌氧消化效果的影响,做出对生活垃圾厌氧消化技术的研究展望,为研究城市生活垃圾厌氧消化技术研究提供理论基础.

With the rapid development of the global economy and the improvement of people s living standards,the production of municipal solid waste is increasing.Waste disposal has become one of the major problems limiting urbanization and urban economic development.This paper reviews the composition classification,characteristics and composition analysis of municipal solid waste,and summarizes the current progress of anaerobic digestion technology for domestic garbage.The technics of dry/wet anaerobic digestion,single-phase anaerobic digestion,continuous/batch anaerobic digestion,and normal/high temperature anaerobic digestion in anaerobic degestion technology of municipal sdid waste were described in detail,explain the effects of organic load,pH and temperature on anaerobic digestion,and the research prospects of anaerobic digestion technology of domestic garbage were made,which provided a theoretical basis for studying anaerobic digestion technology of municipal solid waste.
