污染河流悬沙与铜、锌污染相关性研究

Study on Correlativity of Suspending Sand and Copper or Zinc in Polluted River

通过对矿区选矿废水污染的河流水样和悬沙进行采样,分析悬沙、铜、锌质量浓度,探讨河流悬沙与铜、锌之间的相关关系,是有重要现实意义的。研究结果表明:河流水质铜超标严重,丧失了作为农业用水的使用功能。水中铜污染物量与悬沙量相关关系,锌污染物量与悬沙量相关关系都是极显著的。经过曲线回归方程拟合,锌污染物量与悬沙量之间的回归关系比铜污染物量与悬沙量之间的回归关系显著,有3个曲线方程较优,即:对数方程、二次多项式方程、三次多项式方程。据此,通过测定污染河流悬沙量可以粗略地估算水中锌污染物量。

It is important to approach the correlations between suspending sand and copper or suspending sand and zinc by analyzing suspending sand concentration and copper content or zinc content in the river which was polluted by ore- dressing wastewater in mine area. The research results show that the copper content in the river surpasses seriously its standard, which means that the water has lost its function as agricultural water. In addition, it is extreme remarkable correlations between copper content and suspending sand content or zinc content and suspending sand content. After imitating some curve equations, the correlation between zinc content and suspending sand content is more remarkable than the correlation between copper content and suspending sand content. There are three better curve equations such as logarithmic equation, quadratic equation and cubic equation. This conclusion indicates that it is able to estimate roughly zinc content in the water according to measuring suspending sand content in the pollution river.
