Sludge is a typical solid waste of sewage treatment plants, and its disposal methods have attracted much attention. This paper summarized the current technical routes for sludge disposal in China, including anaerobic digestion, anaerobic fermentation, incineration, landfill, land utilization, and building materials utilization. In the context of energy saving and carbon reduction and the promotion of resource recovery, enhanced pretreatment technology of sludge anaerobic digestion and anaerobic fermentation technology for fuel gas production are the first choices for sludge disposal and resource utilization. In addition, the development trend of sludge disposal technology was analyzed.
