经验公式分析法预测河流汛期污染

River Prediction of Pollution in Flood Season with Experience Formulas

基于淮河流域淮河干流、沙颍河、洪河COD污染通量与河水径流量有较好相关性 ,结合汛前河流污染特点分析 ,提出了这些河流汛期污染预测经验模式。由 2 0 0 1年汛期实际污染情况对COD污染负荷与COD浓度预测结果的检验表明 ,对汛期初期阶段的预测误差在± 1 3%以内 ,根据预计降雨量对河流径流量的估计范围覆盖实际情况。

The article advances the experience formulas to predicte pollution in flood season of Huai River,Shaying River and Hong River.The formulas based on the COD load is directly related to the amount of flowing water.The examination by practices shows that the prediction error of COD load and concentration is less than 13%.
