Treatment of Electroless Nickel Plating Wastewater by Ozone Oxidation

Electroless nickel plating technology is also called chemical nickel plating, which is an important nickel plating method. However, the wastewater produced by electroless nickel plating contains a large amount of phosphorus and nickel. The heavy metal nickel is carcinogenic and has sensitizing effects. It is also toxic to environmental organisms. Phosphorus is a well-known factor that leads to eutrophication of water bodies. How to effectively deal with the waste solution of chemical nickel plating, turning the environmental pollutants into recyclable resources, and reducing the damage to the ecological environment are of great significance. This article applies ozone to the treatment of nickel wastewater. Its success brings the possibility of developing a new method for the treatment of nickel wastewater.
