摘要
相对于传统厌氧消化,污泥高含固厌氧消化具有反应器容积小、有效容积沼气产率高、建设和运行成本低等优势。从技术优势、控制参数、消化性能、存在问题和优化方式等方面,对污泥高含固厌氧消化系统进行了综述。通过调控优化污泥高含固厌氧消化过程控制参数,采用多种预处理技术耦合+厌氧消化/混合基质共消化等工艺形式,可以有效解决污泥高含固厌氧消化搅拌困难,传质、传热效果差,中间产物积累抑制等问题,并提高其厌氧消化性能。实践表明,高含固厌氧消化是污泥厌氧消化技术发展的重要趋势之一。
High-solids anaerobic digestion(HSAD) of sewage sludge shows the advantages of smaller reactors, larger volumetric biogas production, lower construction and operation cost compared to traditional anaerobic digestion technology. In this paper, the technological superiority, control parameters, digestion performance, existing problems and optimization methods of sewage sludge HSAD were reviewed. It can be inferred that the problems of agitation difficulties, poor mass transfer and heat transfer effects, and the accumulation and inhibition of intermediate products during sewage sludge HSAD can be effectively solved by adjusting and optimizing the control parameters of sewage sludge HSAD and adopting a variety of pretreatment process coupling plus anaerobic digestion/co-digestion and other technological forms. Moreover, the anaerobic digestion performance can also be improved. HSAD is an important trend in the development of sewage sludge anaerobic digestion technology.
