Abstract: The sludge drying incineration heat treatment technology is created to realize the complete reduction, stabilization and harmless disposal of sludge. This paper puts forward the concept of "BIM+ Digital+ Intelligent" and systematically sorts out the BIM forward design system of sludge drying and incineration project. The EPC management method based on unified coding has been formed and a variety of BIM-based digital software has been developed to improve the quality and efficiency of EPC project management, which helps improve the quality and efficiency of engineering construction management, and provides a reference for the design and construction of digital intelligent large-scale sludge drying incineration plant in the future.
