高级氧化技术降解有机选矿药剂的研究进展

残留有难降解有机浮选药剂的选矿厂废水直接排放会污染环境，回用于磨矿或浮选流程会影响分选指标，高级氧化技术是一种有前景的水处理技术。为促进高级氧化技术在此类废水处理中的应用，系统介绍了臭氧及其复合氧化技术、Fenton氧化法、光化学氧化法、光催化氧化法、电催化氧化法及过硫酸盐氧化法降解有机选矿药剂的降解效率、工艺原理等方面的研究结果，并对高级氧化技术处理选矿废水的应用前景进行展望。

Research Progress on Degradation of Organic Mineral Processing Reagents by Advanced Oxidation Technology

The environment will be polluted for direct discharge of concentrator wastewaters with refractory organic flotation reagents， and the reuse of untreated wastewater in the grinding or flotation process will affect the separation indexed. Advanced oxidation technologies（AOPs） are one of promising water treatment technologies. In order to promote the application of advanced oxidation technologies in such wastewater treatment， the research progress of degradation efficiency and process principles of organic reagents by ozone and its combined oxidation technology， Fenton oxidation， photochemical oxidation， photocatalytic oxidation， electrocatalytic oxidation and persulfate oxidation for degrading reagents were introduced systematically. And the application prospect of advanced oxidation technology for the treatment of mineral processing wastewater was predicted.
