城市生活垃圾厌氧消化处理技术的应用研究进展

Application and Research Advances on Anaerobic Digestion for Municipal Solid Waste Treatment

总结了国内外可生物降解有机城市生活垃圾(BOFMSW)厌氧消化处理技术的应用和发展概况。详细分析了垃圾成分、碳氮比、接种物、温度、pH值、总固体含率、有机负荷率以及搅拌对BOFMSW厌氧消化的影响。介绍了国内外厌氧消化法处理可降解有机垃圾的几种工艺,比较各种工艺类型的特点,并辅以实例分析。最后指出我国利用厌氧消化技术处理BOFMSW,以及城市生活垃圾综合利用两个层面存在的问题,并给出了我国城市生活垃圾的厌氧消化技术研究和应用的发展方向。

This paper summarized the present situation and development of anaerobic digestion of the biodegradable organic fraction of municipal solid wastes（BOFMSW）. The effects of waste composition, C/N, inoculums, temperature, pH level, total solids, organic loading rate and mixing on anaerobic digestion were discussed in detail. The current classic anaerobic digestion processes were introduced and illustrated by the case study. The advantage and disadvantage of processes were compared. The current drawback of anaerobic digestion of BOFMSW and integrative management of MSW were directed and the research directions of anaerobic digestion of BOFMSW in China were proposed.
