Abstract :
The present paper mainly is take rare earth waste residue as a material, carries on modified processing to it, and carries on decolorization processing with it to the waste water. The research indicated the preparation condition is: The HCl density is 10%, modified temperature 60-70degC, modification process time 48 h, rare earth waste residue size 900 item; The good process condition is: pH=9.0, dosage 0.1 g/L, settlement time 36, mixing speed 200~300 r/min, the waste water density is lower than 15 mg/L, decolorization rate reaches above 97%, the COD elimination rate reaches 90%.
