Abstract

This article introduces the industry background of urban sewage sludge resource utilization in our country, analyzes the current research status of comprehensive sludge resource utilization, and elaborates on key technologies such as sludge and biomass co-pyrolysis gasification, carbon-silicon separation, and waste heat utilization. Application cases indicate that this project has created a "full industrial chain of sludge drying, pyrolysis gasification energy recovery, and comprehensive carbon utilization," which has significant economic and social benefits and serves as a good demonstration.
