Post Evaluation of Upgrading Process,Construction Cost and Operation Cost of 9 WWTPs in Southern Area
With the improvement of the effluent discharge standard of wastewater treatment plants(WWTPs),domestic WWTPs have been upgraded one after another.This time,for the 9 WWTPs upgraded in Guangdong Province during the same period,the quality of the water entering and leaving the factory,the existing biochemical treatment process,the design parameters of the upgrading process,groundwater and geological conditions,etc.,are compared.The consideration factors of different upgrading process selection are analyzed and summarized.At the same time,according to the settlement of the upgrading project of these 9 WWTPs,the cost index of each WWTP upgrading project,the civil construction cost index of each process structure,the equipment cost cost index,and other special cost index are compared,and the approximate range of different upgrading process engineering cost index is analyzed and summarized.It provides reference for the design and decision of similar WWTPs upgrading project in the future.
