Abstract

Taking the cascade pumping station project of the East-Line of South-to-North Water Diversion Project as the research object, the simulation study of sudden water pollution accident and the emergency dispatch control of gate and pump are carried out. The one-dimensional hydrodynamics and water quality numerical model of the cascade pumping station with sudden water pollution accident were established to study the transformation law of pollutant transportation and forecast its impact on water quality. Considering the propagation speed of pollutants and the variation of channel water level, the emergency control mode of pump station and backwater gate under water pollution accident is put forward. On the basis of this, the rules and schemes of pumping station and backwater gates are worked out. The variation range of the pollution group, the variation of the water level of the channel, the discharge quantity and so on under different control schemes are simulated and analyzed. Finally, the optimal pump station and gate scheduling control scheme is selected to effectively control the water pollution accident and ensure the safety of pump stations and channels. The research results can provide technical reference for emergency control of sudden water pollution accident in the east cascade pumping station project.
