Nanoballs can help wastewater undergo deep detoxification

On December 7, 2012, news reported on a tiny sphere, about the size of a grain of sand. Its interior is ingeniously structured into a series of small compartments, meticulously arranged with extremely fine nanomaterials. When countless such spheres are gathered in a filtration device, toxic and harmful substances in domestic and industrial wastewater are instantly adsorbed and separated. The water purification results far exceed current national standards. 36-year-old Pan Bingcai, director of the Department of Environmental Engineering at Nanjing University, and his team have developed a world-leading environmental nanotechnology control and wastewater advanced treatment technology. He was selected as one of Jiangsu Province's Top Ten Young Scientists and Technologists this year.

Methods for treating copper ions in industrial wastewater

Copper plating is often used as an underlayer for nickel, tin, chromium, silver, and gold plating to improve the bonding strength between the substrate metal and the surface plating and the corrosion resistance of the plating. Therefore, copper-containing electroplating wastewater is very common in the electroplating industry, and this type of wastewater usually contains various heavy metals and complexing agents. Currently, the treatment of copper-containing electroplating wastewater mainly uses chemical methods, ion exchange methods, membrane separation methods, adsorption methods, and biological methods. 1 Chemical methods for treating copper-containing electroplating wastewater 1) Neutralization precipitation method Currently, chemical neutralization and coagulation precipitation methods are commonly used in China to treat copper-containing comprehensive electroplating wastewater. The neutralization of acids and alkalis in the wastewater is
