Abstract:The sludge collaborative treatment and disposal technology can take advantage of synergy, reduce costs, save original resources, effectively reduce carbon emissions, and has the significant economic benefits and application potential. Focusing on the relevant regulations, standards and application status of sludge collaborative treatment and disposal technology at home and abroad, the policy orientation and standard requirements of domestic technologies are sorted out, and the typical engineering application and the general technological features are analyzed. Then, taking Germany and Japan as the examples, the laws and regulations related to the sludge treatment and disposal under the different national conditions are investigated as well as the current status and development trend of sludge collaborative treatment and disposal technology in these countries. Finally, based on the current status of sludge collaborative treatment and disposal at home and abroad, the development trend and suggestions of this industry are summarized to provide the reference for its popularization and application.
