摘要
在易氧化的硫化物矿物尾矿上叠加生活污水或乙酰丙酮等阻断尾矿向酸性矿山废水转移过程中,引发了硫化物矿物氧化产生的还原性硫与有机污水中一些水溶性有机物以及乙酰丙酮的作用,生成以CS2为主的新的二次污染物.
Oxidation of sulfide mineral generates acid mine wastewater. In the current treatment technology, domestic wastewater or acetyl acetone has been used in preventing the oxidation of sulfide mineral. But the research of the this paper suggests : the reaction of sulfide mineral with domestic wastewater ( or acetyl acetone) can produce volatile sulfur gases. The domestic wastewater was derived by methyl chloroformate and detected by GC-MS, and was found to countain various water-soluble organic compounds. The oxidation process of sulfide mineral can producte polysulfide. It is possible that the reaction of polysulfide and water-soluble organic compounds can producte volatile sulfur gases (CS2or COS), to cause secondary pollution.
