【摘要】 对南淝河河流水质S-P模型中碳化BOD衰减系数K1和大气复氧系数K2分段进行了估值。根据实验测定数据,用最小二乘法、图解法和两点法等3种方法对K1进行了估值,应用公式估算法对K2进行了估值,并对估值的结果与南淝河的有机污染状况进行了对比和分析,从而为模型提供准确的参数值,也为南淝河的水污染控制和水质规划提供有益的借鉴。更多还原

【Abstract】 The parameters of StreeterPhelps(SP) water quality model for Nanfeihe River,the coefficient K1 of carbonized BOD attenuation and the coefficient K2 of atmospheric restoration are assessed with respect to different sections of the River. Based on the data measured in the experiment, K1 is estimated by using the method of least squares,the graphical method and the twopoint method,and K2 calculated by using theoretical and experiential formulas. The estimation results are analyzed by comparison with the organic pollution situation of the River. Then the accurate values of the parameters can be provided for the model,and the results are also beneficial to the water quality planning of the River and the water pollution control.更多还原
