摘要
从小浪底水库运用后水沙条件的改变入手,进行了污染源发展趋势预测,然后根据二维水质方程,以工业发展速度、工业污染负荷以及断面背景浓度为预测组合条件,预测了孟花段在2010年水平年CODCr浓度的变化趋势。结果表明,在各种组合条件下CODCr浓度均严重超标,为进一步开展水污染控制工作奠定了基础。
Starting from the variations in water-sediment conditions after Xiaolangdi reservoir operation, the developing trend of pollution sources is predicted. And then, based on two-dimentional water quality equation, and with industrial development speed, industrial pollution wading and cross section background concentration as the predicting combination conditions, the varying trend of COD Cr concentration of the average years in the year of 2010 in Mengjin-Huayuankou section is predicted. The results indicated that under the conditions of various combinations, COD Cr concentration exceeds the norms seriously, whereby laying a solid foundation for farther implementing water pollution controlling work.
