| Abstract: | The production process and characteristics of ammonia saponification wastewater form extraction separation for the rare earths were introduced. The treatment methods and elimination methods for the saponification wastewater were presented. The electrolysis saponification was put forward. The main treatment methods for the saponification wastewater are concentrating crystallization, evaporating ammonia and adsorption. The main eliminating methods are sodium saponification and electrolysis saponification. The chemical principles of evaporating ammonia, sodium saponification and electrolysis saponification were recommended. The atom utilization of electrolysis saponification is 100% . |
