Description

Technical Field

[0001] The utility model relates to the technical field of mine wastewater catalytic devices, in particular to an acid mine wastewater catalytic device. Background Art

[0002] With the continuous mining of mineral resources, metal mines produce a large amount of acidic wastewater during the production process. These wastewaters usually contain high concentrations of sulfuric acid and heavy metal ions such as iron, copper, zinc, etc., which pose a serious threat to the environment and ecosystem. If these wastewaters are discharged directly without treatment, they will not only pollute surface water and groundwater, but also damage the soil and vegetation, thereby affecting human production and life.

[0003] Traditional methods for treating acidic mine wastewater mainly include neutralization reaction, precipitation, adsorption and biological treatment. However, these methods have certain limitations in practical applications. For example, neutralization reaction requires a large amount of alkaline reagents, which is costly and easily produces a large amount of precipitates, increasing the difficulty of subsequent treatment. Although precipitation can effectively remove heavy metal ions in wastewater, the treatment and disposal of precipitates is also a major problem. Although biological treatment is environmentally friendly, it takes a long time to treat, and the adaptability of microorganisms to acidic wastewater is limited.

[0004] In order to solve the above problems, researchers began to explore catalytic treatment technology for acidic mine drainage. Catalytic treatment technology accelerates the chemical reaction rate and improves wastewater treatment efficiency by adding catalysts to wastewater. Compared with traditional treatment methods, catalytic treatment technology has the advantages of fast reaction speed, high treatment efficiency and relatively low cost.

[0005] However, existing acid mine wastewater catalytic devices on the market, while equipped with a catalyst storage tank, are generally only used to store liquid catalysts. When encountering solid catalysts, although a solution can be added to dissolve the solid catalyst before use, the solid catalyst takes a long time to dissolve, and the solid catalyst cannot be directly crushed and then dissolved in the corresponding solvent, which delays processing time and causes inconvenience to the user. In view of this, we have proposed an acid mine wastewater catalytic device. Utility Model Content
