Reconstruction and Commissioning of Non-Stop Advanced Treatment in Shanghai N WTP
The design scale of the advanced treatment project of Shanghai N WTP is 440 000 m3/d.O3-BAC advanced treatment process is adopted.Considering the process characteristics and in conjunction with the engineering construction and operational conditions of the WTP,a non-stop deep treatment engineering renovation is implemented.During the construction and commissioning stage of the deep treatment transformation project,Shanghai N WTP effectively solve the engineering difficulties such as the protection of the original water discharge pipe and the collision and connection of new and old pipelines.It also formulates the plans for single machine commissioning,linkage commissioning and full load commissioning.In the implementation process,through strengthening the washing of structures and pipelines,adding CO2 to regulate the pH of backwashing water of carbon filter,it ensures the connection between the deep treatment transformation project and the existing production system,and solves the problem of noise reduction of drainage valves.After commissioning,all indices of the water leaving the factory have fully met the requirements of Standard for Drinking Water Quality(GB 5749-2022)and local water quality standards in this region.
