【摘要】 应用野外实验池实测及模式模拟等实验与计算方法对松花江水中２３种有机污染物的迁移转化行为进行了模拟研究．应用３个小型野外实验池于江边现场、经７２ｈ、３个不同实验条件的同时测定，得到各池条件下，每一化合物表观总一级动力学常数．由之估算了挥发性有机物的挥发速率常数、硝基芳烃的光解速率常数．建立了适于实验池及河流的箱式模型．应用箱式模型及所得上述参数，数学模拟了污染物在实验池及江水中变化规律，得到与实际符合的结果．更多还原

【Abstract】 The behavior of twenty three organic pollutants in Songhua River was investigated by using experimental pools at riverside. The change in the concentrations of the compounds in the pools could be well described by an experimental pools (compartmental) model. K p values of nitro compounds and K v values of eleven volatile organic compounds were estimated from the total quari first order rate constants ( K ) obtained. The values of K p and K v were more suitable for modelling the system than the data collected in laboratory. A river (compartment) model was developed to predict the behavior of the organic pollutants in the Songhua River, the kinetic parameters obtained from the experimental pools were corrected based on the river conditions and used in the model. The model was verified by the measured data from a survey.更多还原
