Application of Sludge Electrolysis Dewatering Technology in a Water Quality Purification Plant in Shanghai

摘要:

污泥电解脱水技术作为一种环境友好的技术，在提升污泥脱水效率、实现剩余污泥减量化具有一定优势。基于上海某水质净化厂污泥电解脱水应用案例，介绍污泥电解脱水设备设计及运行参数、运行情况。与传统板框压滤脱水工艺和热干化工艺进行经济比较，运行能耗降低44%~56.7%，占地面积节约30%以上，运行管理更加便利。

Abstract:

As an environmentally friendly technology, the sludge electrolysis dewatering technology has certain advantages in improving the sludge dewatering efficiency and realizing the reduction of surplus sludge. Based on the application case of sludge electrolytic dewatering in a water quality purification plant in Shanghai, the design, operation parameters and operation situation of sludge electrolytic dewatering equipment are introduced. Compared with the traditional plate frame pressure filtration dewatering process and hot drying process, its operation energy consumption is reduced by 44%~56.7%, the floor area is saved by more than 30%, and the operation management is more convenient.
