| 摘 要： | 本文运用模式计算方法对黄河水体中重金属的形态分配进行了研究。结果表明,pH是控制重金属形态分配的最重要因素,其次是重金属的初始浓度和悬浮物含量。并得出,在黄河水体中,cu、Pb主要以沉淀态存在,zn则以吸附态为主,水体中游离态重金属含量很低。上述结果将为拟建中的小浪底水库工程的重金属环境影响预测提供一定的科学依据。

| Abstract: | In this paper, the model calculation is used to calculate the chemical species distribution of heavy metals in the Middle Yellow River. The results show that the pH value is the most important factor to control the distribution of each species, while the initial concentration of the heavy metals and content of suspended matter are other factors.In the Middle Yellow River, Cu and Pb mainly appear in sedimentary form, and Zn in adsorbed form. The content of free state heavy metal is very low. This study provides a scientific basis for forecasting the effect of heavy metal on environment for building the Xiao Lang Di reservoir. |
