In order to remove the calcium and magnesium ions in ammonium sulfate wastewater,ensure subsequent trouble-free operations of water treatment process,improve quality of ammonium sulfate solid and recover magnesium re-source,the calcium and magnesium ions in ammonium sulfate wastewater are removed with solvent extraction method in ex-periment. The P204 and kerosene are used as extractant as well as pH value of ammonium sulfate wastewater and saponifica-tion degree of P204 are adjusted so that the step-by-step removal of calcium and magnesium ions in ammonium sulfate wastewater is realized. The data support for industrial applications of this method is provided by such experimental condi-tions as determining pH values of the solution and comparing.
