摘要
随着城市人口数量的增加,污水处理量增多,随之而来的污泥处理量越来越大。厌氧消化是实现污泥减量化、稳定化、无害化、资源化的重要处理途径。目前厌氧消化技术不够成熟,有机质去除率低和产甲烷率低是污泥厌氧消化发展的瓶颈。本文从污泥预处理、厌氧反应器新模式、新材料的应用、协同消化四个方面综述了强化污泥厌氧消化产甲烷技术进展。
The amount of waste water increases and the amount of waste activated sludge increases consequently, with the amount of urban population rising. Anaerobic digestion is a crucial method to achieve sludge reduction, stabilization, harmlessness and recycling. Currently, the technology of anaerobic digestion is developing, low removal rate of organic matters and low methane yield restricting the development of anaerobic digestion. The progress of enriching methane production from anaerobic digestion of sludge was reviewed in four aspects： sludge pretreatment, new model of anaerobic reactor, application of new materials and co-digestion in this paper.
