摘要
分析了城市生活垃圾厌氧消化的基本原理和高温干式厌氧消化工艺,温度对干式厌氧消化的影响,随着固含率的升高,中低温已不能满足厌氧消化的要求。对城市生活垃圾的湿式/干式厌氧消化工艺进行了比较,同时介绍了干式厌氧消化/好氧堆肥工艺。厌氧生物处理技术是进行城市生活垃圾的无害化、减量化、资源化处理,实现垃圾循环利用的较好的方法。
The basic principle and process of high-temperature dry anaerobic-digestion for treating municipal solid wastes （MSW） were introduced in this paper. Temperature is one of the major factors influencing dry anaerobic digestion. When the concentration of TS goes up, a digestion temperature under 35℃ can not meet the needs for dry anaerobic fermentation process. The dry and wet anaerobic digestion processes for MSW treatment were compared, and the dry anaerobic digestion-aerobic composting process was discussed as well in the work. It was concluded that the anaerobic biological process is suitable for MSW treatment to achieve the target： minimization, harmlessness and resource recovery.
