| Abstract | Shanghai, an industrial and commercial centre in China, has been seriously facing the scarcity of quality water in recent years. Water quality of most rivers fail to meet the required standards. Thereforn, Shanghai Municipal Government (SMG) has implemented a series of projects for rehabilitation of rivers and improvement of quality of water for supply, also known as Shanghai Environmental Projects (SEP), since mid 1980's. Especially the Huangpu River, which is the main water source of Shanghai, has received much attention. In this study, water quality management activities and water quality status were presented and evaluated. Then, a dynamic finite element water quality model was established by using VisSim - a dynamic modelling software to simulate the DO-BOD and nitrification processes and to qualitatively assess the impacts of pollution loads on water quality. Calibration for determination of its main coefficients and validation of the model was successfully carried out in terms of water quality parameter BOD5, DO and NH3-N based on the collected data. Finally, the model was applied for prediction of water quality and evaluation of current management strategies. The results of the study show that water quality of Huangpu River fails to meet standards and has a tendency of decreasing. And the current control measures seem to be of short-term. It is recommended that the better solution may be upgrade existing treatment facilities, strengthen management and supervision both for point source and non-point source pollution. |
