description The invention belongs to the technical field of wastewater treatment, and provides a rare metal industrial wastewater treatment process. Rare metal industrial wastewater is sequentially subjected to the steps of solid-liquid separation, slagging, solid-liquid separation, electrolysis, solid-liquid separation and the like. Composite adsorption macroporous resin is added in a slagging process; an ion exchange membrane is activated before electrolysis; oxygen is introduced into an anode chamber during the electrolysis process; and an ultrasonic treatment process is carried out after electrolysis,so that the decomposition rate of oxalic acid is improved, the acid recovery rate is improved, and removal rates of Mg, Ca and chemical oxygen demand (COD) are increased. Acid resources in the wastewater are recycled again, the impurity content is reduced, and requirements of the emission standard are greatly met. 本发明属于废水处理技术领域，提供了种稀有金属的工业废水处理工艺，将稀有金属的工业废水依次进行固液分离、造渣、固液分离、电解、固液分离等步骤，通过造渣过程中加入复合吸附大孔树脂，电解前活化离子交换膜，电
