In view of the sudden water pollution events in the main stream of Minjiang River, taking the lower reaches of the main stream of the Minjiang River as the study area, a coupling model of hydrodynamic and water quality was established to accurately simulate the flow dynamics and water quality changes under different scheduling scenarios. By comparing four different scheduling strategies: background simulation (i.e. no special scheduling measures), single optimization of Qianwei Avionics Water Conservancy Project, single optimization of Longxikou Avionics Water Conservancy Project, and joint optimization of two projects, this study comprehensively evaluated the emergency treatment ability of each strategy for water pollution in the main stream of the Minjiang River. The results show that from the point of view of pollutant concentration peak and pollutant exceeding standard time, the joint scheduling strategy of increasing the sluice flow of two hub projects simultaneously shows the best pollution group disposal effect. This strategy not only significantly reduces the peak concentration of pollutants, but also effectively shortens the period of time when pollutants exceed the standard, thus minimizing the negative impact of water pollution on the environment and ecology. The research results can provide reference for the emergency treatment of the Minjiang River main stream water pollution incident and improve the emergency treatment efficiency.
