摘要:
污泥干化是污水处理厂市政污泥处理处置过程中的一个重要环节。白龙港污水处理厂作为亚洲规模最大的污水处理厂，已建成并成功运行了国内首座污泥厌氧消化+干化处理工程，以及目前全世界规模最大的污泥单独干化焚烧项目，均采用流化床干化工艺对污泥进行干化。工程应用中，流化床干化处理能力均可满足设计要求，并可充分实现与污泥消化系统及污泥焚烧系统的有机结合。干化热源、系统换热方式的选择充分考虑了不同衔接工艺的特点，节约了能源和资源消耗。流化床干化系统能够安全、稳定运行，干化系统产生的冷凝水、载气等得到妥善处置，臭气污染物得到控制。
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.
