Abstract

Abstract

The treatment and disposal of municipal sewage sludge started late in China, and yet multiple utilization ways and industrialization promotion are still being explored, of which economy is an important factor related to the success of the technical application path and realization of the technical system. “Anaerobic digestion+land use” is one of the mainstream treatment and disposal technical routes of municipal sewage sludge in China. Focusing on “traditional anaerobic digestion+land use” and “advanced anaerobic digestion+land use”, based on the unified accounting method of the whole process operation cost, economic efficiency, and change rules under different sludge characteristics or technical conditions were analyzed. Besides, this study discussed the interaction between economy and technology implementation and put forward optimization suggestions for the application and promotion of the “anaerobic digestion+land use” technical route through economic analysis. This study can provide a basis for the top-level design and technical route selection of municipal sewage sludge treatment and disposal, provide a reference for project operators to evaluate and improve the operation level, and provide support for the promotion and realization of municipal sewage sludge harmless treatment and resource utilization.
