摘　　要：厌氧消化目前已广泛应用于市政污泥、有机废水、城市有机垃圾、养殖粪便等有机废弃物的资源化处理,由于其具有在实现有机废弃物处理的同时产生甲烷燃料,剩余物还可以作为肥料使用的优点,全球各地已建立了许多大规模的厌氧消化工厂。温度是影响厌氧消化的重要因素,中温和高温厌氧消化是目前常采用的两种工艺,二者各有优劣,但是我国存在对高温厌氧消化的重视程度远远不及中温厌氧消化的问题。因此,本文首先对中温和高温厌氧消化及比较两种工艺的中英文文献进行了统计分析,然后重点从运行参数、有机物降解率、系统稳定性、产沼气性能、消化污泥特性(包括脱水性能、起泡潜力和病原菌含量)和微生物特性等运行性能、厌氧消化模型、经济效益和应用现状等方面对中温和高温厌氧消化进行了详细的比较,并对厌氧消化的应用和发展提出了建议。Anaerobic digestion(AD)has been widely applied to recycle organic wastes such as sewage sludge,organic wastewater,municipal organic waste and livestock manure.Because it can produce methane and fertilizer while treating organic waste,many large-scale AD plants have been established around the world.Temperature is an important factor affecting AD,and mesophilic AD and thermophilic AD are two commonly used technologies.Although the two ADs have their own advantages and disadvantages,thermophilic AD has been attached far less importance than mesophilic AD in China.Firstly,this paper made a bibliometric analysis on Chinese and English papers about the two ADs and their comparisons.Then,a detailed comparison of the two ADs was made based on their AD models,economic efficiencies,application status,and operating performances,such as operating parameters,organic matter degradation,system stability,biogas performance,digestate properties(sludge dewatering ability,foaming potential and pathogen content)and microbial characteristics.Additionally,the suggestions for the application and development of the two ADs have been put forward.
