Highlight: Qingcaosha Reservoir -- World's First-Biggest inland river estuary reservoir
Nanshi Water Treatment Plant -- Shanghai's First Digital Twin Water Treatment Plant
Technical Tour 1: Qingcaosha Reservoir
As the largest estuary reservoir in the world , Qingcaosha Reservoir is located in the south and north passage bifurcation of Yangtze River, northern ChangxingIsland. The reservoir was built in 2011 with an effectivestorage capacity of 553 million m³. lt is able to provide 7.31 million m³ raw water per day, accounting for over 50% of the total raw water supply in Shanghai, serving over 13 million people. Qingcaosha Reservoir had been suffering the MlB episodes since it was put into use. lt is equipped with multiple on-line monitoringsensors to check variations of water quality. A model has been developed to predict the occurrenceof MlB producing cyanobacteria. The under water light restricting approach has been adoptedsuccessfully for the in-situ control of MlB producing cyanobacteria since 2020.
Technical Tour 2: Nanshi Water Treatmen Plant
As the first digital twin water treatment plant in Shanghai, Nanshi Water Treatment Plant isclosed to the Huangpu River. The water treatment plant was first built in 1902 and rebuilt in2009, with a water supply capacity of 700,000 cubic meters per day. The unmanned laboratoryproject of Nanshi Water Treatment Plant has achieved full automation and unmanned operationof water quality testing, covering the detection of 13 routine indicators. This laboratory adopts amodular design, featuring high replicability and scalability. lt supports continuous operation andcan adjust the testing efficiency as needed.
