Sludge Drying Project Design of Guangzhou Health City Water Purification Plant
The long-term design scale of the sludge drying project of Guangzhou Health City Water Treatment Plant in Guangdong is 27.3 tDS/d,and the short-term equipment installation scale is 18.2 tDS/d.The dewatering and drying process of sludge thickening+conditioning+frame dehydration+thermal drying is adopted,and the sludge drying facilities and main structures are located in the underground layer.After the completion of the project,the operation effect is good,the continuous and stable operation has been achieved,the odor has been effectively controlled,the odor emission level is higher than the current domestic standard requirements,and the project has successfully passed the environmental protection acceptance.This paper introduces the design scale,design parameters and design content of the sludge drying room in detail,focuses on the calculation of material balance,heat balance and operation cost of the project,and summarizes the main design characteristics.
