Taking the typical canal section in East Route Project of South to North Water Diversion as an example, the simula-tion of the sudden water pollution accident and the emergency control of the sluices and pumping stations are researched. By u-sing the one-dimensional hydraulic and water quality model in canal, the transport and transformation laws of pollutant are dis-cussed and its influence on water quality is predicted. Aiming at the conditions of water level variation and the propagation speed laws of pollutants, the pollutant control mode of pumping stations and exit sluices are researched. On this basis, the controlling regulations and schemes for pumping station and exit sluice are determined and the diffusion range, the water level vibration scope and the water release amount under different controlling schemes are simulated. The optimum co-operation scheme of sluices and pump stations is suggested and the safety of the canal is ensured.%以南水北调东线工程两湖段梯级泵站为研究对象，开展了突发水污染事故仿真模拟及闸、泵应急调度控制研究。利用突发水污染事故工况的梯级泵站输水一维水动力学和水质数值模型，探讨了污染物输移转化规律，预测其对水质的影响；针对污染物的传播速度、渠道水位变幅等限制条件，提出水污染事故下泵站及退水闸应急控制模式；在此基础上制定泵站和退水闸控制规则和方案，模拟分析不同控制方案下污染团扩散范围、渠道水位变幅、泄水量等参数变化情况，最终优选出最优泵站、闸门联合调度控制方案控制水污染事故，同时保证泵站及渠道的运行安全。研究成果可为东线梯级泵站工程突发水污染事故应急控制提供技术参考。
