摘　　要：高含固厌氧消化具有所需反应器体积小、能量需求低、沼渣产量少以及沼渣后续处理简便等优点,是实现固体废弃物资源化的重要途径,因此对高含固厌氧消化性能的认识非常重要。本文重点阐述了原料、接种、含固率、温度、碳氮比和颗粒粒径等影响高含固厌氧消化性能的主要因素及其研究进展,指出这些因素通过改变启动性能、甲烷产量、挥发性固体(VS)降解率和系统稳定性等对高含固厌氧消化过程产生影响,且每个因素对消化性能的影响都至关重要。此外还指出,对污水厂剩余污泥的高含固厌氧消化将会成为我国颇具应用前景的处理技术,并从各个影响因素出发对高含固厌氧消化技术的实施提供了运行参数和优化措施,以期为高含固厌氧消化技术的进一步完善提供借鉴。High-solid anaerobic digestion, characterized by smaller reactor volume, less energy demand,less amount of residue and more convenient follow-up treatment,is an important method to realize the recycling of solid waste. This paper introduced the effects of the factors such as raw material, inoculation, solid content, temperature, carbon and nitrogen ratio and particle size, on high-solid anaerobic digestion process in detail, and pointed out that these factors were all of great significance and impacted the high-solid anaerobic digestion through changing the startup performances,methane production,volatile solids（VS） degradation rate and system stability. It would be a promising method for high-solid anaerobic digestion to dispose the sludge from domestic wastewater treatment plants. In addition, operating parameters and optimization measures in terms of different factors were provided for the application of high-solid anaerobic digestion in order to help furthering the technology.
