As the rapid development of urbanization in China in recent years,the construction of urban drainage networks is becoming increasingly perfect,and the amount of sewage treatment is gradually increasing,resulting in an increasing amount of sludge.Based on the current research status at home and abroad,this article compares the advantages and disadvantages of several main treatment methods for pipeline sludge,and analyzes the harmless and resourceful disposal of pipeline sludge from the perspective of resource utilization of inorganic and organic matter.At present,the main treatment methods cannot fully solve the problem of harmless and resourceful disposal of municipal canal sludge.Based on the current dual carbon strategy and pollution reduction and carbon reduction plan,a closed-loop resource management approach for the production of green substrates through aerobic fermentation composting for the collaborative disposal of pipeline sludge and landscaping waste is proposed.
