自从二十世纪初发现泡沫浮选以来,现已成为一门现代物质分离和分选的技术学科,它正在从矿物原料分选领域向各工业部门、各学科领域深入扩展,并取得了好的成绩。早在1902年,C.L.Peck就对浮选法处理废水进行了试验研究,但在工业规模上应用,则始于六十年代,到了七十年代才臻于完善。在最近十几年间,废水的浮选法净化才得到迅速发展。其主要用于处理各离子浓度变化较大的矿山废水、含重金属离子较低的废水以及含放射性元素、含油、含表面活性剂等的废水。
Since the discovery of froth flotation at the beginning of the twentieth century, it has become a technological discipline for the separation and sorting of modern materials. It is expanding from the field of mineral raw material selection to various industrial sectors and disciplines and has achieved good Score. As early as 1902, C.L. Peck did experimental research on flotation wastewater treatment, but on the industrial scale, it began in the 1960s and was not completed until the 1970s. In the recent ten years, the purification of wastewater flotation has been rapid development. It is mainly used for the treatment of mine wastewater with large variation of ion concentration, waste water containing less heavy metal ions and wastewater containing radioactive elements, oil and surfactant.
