Abstract:

According to the characteristics of water pollution in Taihu Lake, this paper summarized major causes of water pollution such as slow water flow, stagnant water exchange, small contamination capacity and pollutants entered into the Meiliang Bay exceeding its environmental capacity, and then proposed key strategies and techniques for water pollution control such as regional comprehensive treatment, total amount control of contamination, and water diversion and regulation. With the application of 2D hydrodynamic and water quality models, the amount of water pollutant capacity in Meiliang Bay of Taihu Lake was calculated. In consideration of water diversion from the Yangtze River to Taihu Lake, this study simulated the effect of water diversion to Meiliang Bay on the water environment. In order to optimize the regulation of the water diversion, the effect of largescale and smallscale diversion was forecasted and compared. The results obtained in the present study may provide scientific bases for water pollution control in Meiliang Bay of Taihu Lake and other similar water bodies.

Key words: Taihu Lake, cause of water pollution, water pollution control, contamination gross control, water diversion and regulation
