摘要
以某河流水文资料为基础,采用Mike Eco lab水质混合模型对COD、氨氮和石油类3项污染因子进行水质模拟,通过调整模型参数,实现模拟值与实测值误差控制在10%以内。预测结果显示,在不同污染物排放情境下,各污染因子变化趋势明显,并提出该河流水环境影响分析。
Based on the hydrological data of a river,the Mike Eco Lab model was used to simulate the three pollution factors water quality,including COD,ammonia nitrogen and petroleum.By adjusting the model parameters,the error between the simulated value and the measured value is controlled within 10%.In the different pollutant emission situation,the prediction results show the pollution factor change clearly.According to the conclusion,the river water environmental impact was analyzed.
