| 摘 要： | 分析了某黄铁铅锌矿尾矿库14年的废水监测数据，研究了高酸、高碱环境对尾矿硫化物重金属溶出的影响，绘制了尾矿库废水pH值与重金属离子浓度的关系曲线，揭示了废水酸化与重金属污染的内在机制，提出了密闭履盖尾矿库以隔绝硫化物与H2O、O2反应产生[H^ ]及在尾矿浆中添加碱性物质以中和[H^ ]、切断重金属离子溶出反应链等根治尾矿库废水酸化与重金属污染的控制技术。 |
| 关 键 词： | 尾矿库 废水 pH值 重金属污染 治理方法 硫化物氧化 金属矿山 |

| Abstract: | This paper analyzed continuous data in a period of 14 years for monitoring wastewater in tailings reservoir of an iron lead zinc pyrtie mine,and investigated the infection of high acid and high alkali situation to heavy metals dissolve from sulfide in tailings.Relation curve of pH value to concentration of heavy metals pollution is revealed.Control techniques of acidification and heavy metals pollution of wastewater in tailings reservoir is put forward,including obturating and overlaying surface of tailings reservoir to isolate contact sulfide with water or oxygen to produce,appending alkali matter to neutralizein order to cut off the reaction chain of heavy metal ion dissolving. |
| Keywords: | Tailings reservoir pH value Wastewater pollution Heavy metals pollution Sulfide oxidization Metals mine |
