Application of Ozone Generator in Mining Wastewater Treatment
Mining wastewater is complex, containing high levels of flotation reagents, COD, heavy metals, and other pollutants that are difficult to treat. Ozone generator , with its strong oxidizing power and no secondary pollution, is an ideal solution for mining wastewater treatment.
Key Application Areas
Beneficiation Wastewater
Ozone generator efficiently degrades residual flotation reagents such as xanthates and dithiophosphates. COD removal rates can exceed 90%, and treated water can be reused or discharged to meet standards.Mine Drainage (Coal Mine Water)
Effectively removes petroleum hydrocarbons and dissolved organics, with oil removal rates around 30% at manageable operating costs.Cyanide-Containing Wastewater
Mature application in gold smelting. After ozone oxidation, total cyanide concentration can be reduced to below 2 mg/L, meeting environmental protection requirements.Heavy Metal Removal
Ozone can synergistically remove copper, manganese, mercury, and other heavy metals, with removal efficiencies above 97%.
Core Advantages
High Efficiency – Strong oxidizing power rapidly decomposes complex pollutants.
Clean – Decomposition product is oxygen, no secondary pollution.
Flexible – Can be used alone or combined with UV, catalysts, and other technologies.
Cost-Effective – Significant cost advantages in applications like cyanide removal.
Development Trends
Ozone oxidation technology is evolving toward catalytic enhancement, multi-technology integration, and automated control. It holds broad prospects in advanced treatment and resource recycling of mining wastewater.
