- Abstract:
- Sludge drying is an important step in the process of municipal sludge treatment and disposal in wastewater treatment plants (WWTPs). As the largest WWTP in Asia, Bailonggang WWTP has built and successfully operated the first sludge anaerobic digestion and drying project in China and the largest single sludge drying incineration project in the world. For both projects, fluidized bed drying process was selected for drying sludge. In engineering application, the capacity of fluidized bed system met the design requirements, and fully realized the combination with sludge digestion system and sludge incineration system. The selection of drying heat source and system heat-exchange mode fully considered the characteristics of different connection processes and saved energy and resource consumption. The fluidized bed drying system operated safely and stably. The condensate and carrier gas produced by the drying system were properly disposed, and the odorous pollutants were effectively controlled.
