The metallurgical industry produces a wide variety of products, with each production process forming its own series, generating large amounts of wastewater, which is one of the main sources of environmental pollution. The primary characteristics of metallurgical wastewater include high volume, diverse types, and complex, variable water quality. Classified by source and features, the main types are: cooling water, acid washing wastewater, dust removal and gas, flue gas washing wastewater, slag flushing wastewater, as well as wastewater from condensation, separation, or overflow in production processes. In various industrial production processes, especially those involving copper product processing, such as copper smelting and wire and cable manufacturing, copper-containing wastewater may be generated. This wastewater contains copper ions or particles, with copper ions being the predominant component.
Copper removal agents for smelting wastewater are specialized chemical agents designed to treat copper-containing wastewater. Primarily composed of polymers derived from formates, these agents remove copper ions and their complexed forms through chelation reactions. They chemically react with copper ions in the wastewater, forming insoluble precipitates or complexes, thereby achieving copper ion removal. Additionally, they have a synergistic effect on removing other heavy metals such as nickel, lead, and mercury.
Copper removal agents for industrial wastewater have advantages such as high treatment efficiency, simple operation, and strong adaptability. Under specific pH and temperature conditions, the copper remover can quickly react with copper ions in the wastewater to form stable precipitates, effectively reducing the copper concentration in the wastewater. At the same time, the use of copper removers can also reduce the treatment time of wastewater and improve treatment efficiency. By using copper removers, we can effectively remove copper ions from wastewater, lower its copper concentration, and prevent environmental pollution. Additionally, the use of copper removers offers the advantages of simple operation, low cost, and high treatment efficiency.
