摘要 采用二维水流水质模型对焦作市黄河流域河道水环境进行了数值模拟,并计算了河道的纳污能力。结果表明:CODMn和NH3-N是最突出的超标污染物,概化的老蟒河、涝河、义井南、温县污水处理厂排污口附近的水质较差,黄沁交叉口附近的水质良好;针对目前水质情况,通过河道的纳污能力模拟计算,确定入河污染物总控制量为190.92 t/a,2010年、2020年、2030年3个水平年污染物削减量的分摊比例为2∶3∶5。 By using two-dimensional mathematical model,the rivers' water environment of the Yellow River basin of Jiaozuo City was simulated,and the pollutants bearing capacity of the rivers was calculated.The results show that CODMn and NH3-N are the most outstanding excessive pollutants,the water quality is bad near the outfall of Laomang River,Laohe River,Yijingnan,and Wenxian sewage treatment plant which is generalized by the model,and the water quality is good near the intersection of the Yellow River and Qinhe River.According to the current water quality conditions,it is determined that the total amount of pollutants discharged into rivers is 190.92 t per year through the calculation of pollutants bearing capacity of the rivers.The pollutant reduction of sharing ratio is 2:3:5 in the year of 2010,2020 and 2030 respectively.
