In order to minimize the losses caused by sudden water pollution incidents,this study uses the MIKE 11 hydrodynamic-water quality coupling model to simulate the sudden water pollution incidents in Benxi section of Taizi River Basin.The results of model verification show that the constructed hydrodynamic-water quality coupling model meets the accuracy requirements.The results of simulating the excessive emission of volatile phenol-containing wastewater in four scenarios show that under the same conditions,the peak concentration of pollutants is positively correlated with emission intensity and instantaneous emission.The closer the discharge site is to the monitoring section,the higher the peak concentration of pollutants;and the emission intensity will not affect the time when the pollutants reach the monitoring section and the peak concentration.The simulation results of excessive emission of different volatile phenols can provide prediction and early warning for sudden water pollution incidents in related rivers,and can also provide reference materials for emergency response.
