Abstract:With the acceleration of urbanization, industrialization, and agricultural modernization, the rapid development of the electronic information industry has generated a large amount of electronic electroplating heavy metal wastewater. This type of wastewater has complex components, stable occurrence, great harm, and certain resource attributes. The currently popular coagulation sedimentation method has the disadvantages of poor treatment effect, large sludge volume, secondary pollution, and cannot be recycled as resources. Based on this, the sources and hazards of heavy metal wastewater from electronic electroplating were summarized, the shortcomings of the current main technologies were analyzed, and the progress and latest research results of the resource treatment of metal ions in electronic electroplating wastewater based on classification treatment and qualitative utilization were systematically introduced. It can provide a reference and technical support for clean production, pollution prevention and recycling treatment of heavy metal wastewater in electronic information industry.
