铜矿选矿废水处理研究现状与展望

铜矿选矿过程产生的废水含有的污染物多,导致周边环境严重污染。随着我国水资源的短缺及环保要求的日益严格,对废水的处理是亟需解决的问题。本文以铜矿选矿废水为研究对象,分析了其来源、基本特征以及对环境的危害性,针对铜矿选矿废水中的固体悬浮物、重金属离子和有机选矿药剂,分别阐述了自然沉降、吸附、絮凝、化学沉淀以及高级氧化等处理方法,并对各种方法的机理及优缺点进行总结分析。探讨了铜矿选矿废水在处理中存在的问题,对废水的治理研究进行展望,应开发高效且生态友好的废水处理新工艺,降低废水对环境的污染,实现废水的高效治理。

Research status and prospect of copper ore beneficiation wastewater treatment

A large amount of wastewater generated in the process of copper ore beneficiation, with large discharge, long water flow time and many types of pollutants, is the main cause of pollution of the surrounding environment, water body and soil of the mine. In this paper, the source, basic characteristics and environmental hazards of copper ore beneficiation wastewater are analyzed, and the solid suspended solids, heavy metal ions and residual organic mineral processing agents in copper ore beneficiation wastewater are treated by natural settlement, adsorption, flocculation, chemical precipitation, Fenton oxidation, O3 oxidation and photocatalytic oxidation, and the mechanisms, advantages and disadvantages of various methods are summarized and analyzed. The problems existing in the treatment of copper ore beneficiation wastewater were discussed, and the future research on wastewater treatment was prospected, and a new process of efficient and eco-friendly wastewater treatment should be developed to reduce the pollution of wastewater to the environment and realize efficient wastewater treatment.
