膜技术在有色金属选矿废水处理中的应用进展

Application Progress of Membrane Technology in Non-ferrous Metal Beneficiation Wastewater Treatment

有色金属选矿废水中含有残留的化学药剂和重金属离子,选矿行业废水无组织排放将直接威胁到该区域的生态环境平衡。膜分离技术具有处理效率高、工艺操作简单、可耦合其他处理技术等特点,目前已广泛的应用于有色金属选矿废水处理领域。本文从有色金属选矿废水的特性出发,介绍了目前膜技术在有色金属选矿废水处理中的应用情况,并对膜分离技术在该领域的发展趋势进行了展望。

Nonferrous metal beneficiation wastewater contains residual chemicals and heavy metal ions. The unorganized discharge of beneficiation wastewater will directly threaten the ecological environment balance of the region. Membrane separation technology has the characteristics of high treatment efficiency, simple process operation, and can be coupled with other treatment technologies. At present, it has been widely used in the field of non-ferrous metal beneficiation wastewater treatment. Based on the characteristics of non-ferrous metal beneficiation wastewater, this paper introduces the current application of membrane technology in the treatment of non-ferrous metal beneficiation wastewater, and prospects the development trend of membrane separation technology in this field.
