Abstract: The invention discloses a method for treating wastewater generated in the spherical nickel hydroxide production process. The invention uses a combined membrane treatment process to systematically and specifically treat process wastewater produced at all stages of the spherical nickel hydroxide preparation process. The concentration of crude wastewater greatly reduces the treatment burden and energy consumption in the evaporation process with obvious environmental protection benefits. In addition, the membrane treatment system has the characteristics of easy control and simple operation. By virtue of the treatment method of the invention, the quality of some produced water can meet the standard of purified water.
