Description

Technical Field

[0001] The utility model belongs to the technical field of wastewater treatment, and in particular relates to a ore dressing wastewater treatment device of coagulation coupled vacuum ultraviolet oxidation. Background Art

[0002] With the continuous increase of global mining activities, mineral processing wastewater has become a serious environmental problem. Mineral processing wastewater usually contains a variety of harmful substances such as heavy metals, suspended solids, organic pollutants, etc. If these substances are directly discharged without proper treatment, they will cause irreversible impacts on the environment. Traditional mineral processing wastewater treatment methods, such as sedimentation, filtration, activated carbon adsorption, etc., although they can remove harmful substances in wastewater to a certain extent, these methods usually have problems such as low treatment efficiency, complex operation, and high operating costs. In addition, these methods can often only treat a certain type of specific pollutants. For complex and changeable mineral processing wastewater, the treatment effect is often difficult to guarantee.

[0003] In recent years, coagulation technology and ultraviolet oxidation technology have gradually attracted attention in the field of wastewater treatment. Coagulation technology can purify wastewater by adding coagulants to aggregate suspended matter, colloidal substances, etc. in wastewater into large particles and precipitate. In mineral processing wastewater, coagulation technology can effectively remove pollutants such as suspended matter and heavy metal ions. Ultraviolet oxidation technology uses the strong oxidizing property of ultraviolet rays to decompose organic pollutants in wastewater into low-toxic or non-toxic substances. However, these single technologies still have certain limitations in practical applications. For example, coagulation technology is not effective in removing soluble pollutants and is prone to produce a large amount of sludge, while ultraviolet oxidation technology is not ideal for treating some difficult-to-degrade organic matter.
