| 摘 要： | 本文研究了含铜、铁和硫酸根离子酸性矿山废水的中和沉淀性质以及沉淀产物的沉降行为,测定了有关沉淀物的粒度组成及其表面电性质。研究结果表明,采用“阶段中和沉淀法”能使虚水中Cu~(2+)和Fe~(3+)分离,便于分别回收铜和铁。文中还根据胶体化学原理,分析了中和pH值对沉淀产物沉降体积的影响。

| Abstract: | This paper studies the characteristics of neutralizing precipitation of acidic mine water containing Cu, Fe and SO_4 as well as the precipitating behaviour of precipitates.The size composition of precipitates and their surface charges are determined. In order to recovery Cu and Fe in the mine water, a staged-neutralizing preciptation is used to separate Cu from Fe.From the principle of colloidal chemistry, the influence of neutral pH value on precipitate volume is analyzed. |
