Abstract: PURPOSE: A treating method of wastewater including phenol sulfonate in tin coating progress is provided, which is characterized in that a proper acidity can be maintained with removing sulfonic acid. CONSTITUTION: Phenol sulfonate which is added in tin coating progress is toxic organic matter, so the content of organic matter is measured accurately before adding peroxide and the second iron ion. The pH of the wastewater is controlled at 2 - 6, and the content of the phenol sulfonate in tin coating wastewater is measured. The second iron ion is added 0.185 - 0.3 g/L per 1 g of phenol sulfonate, and peroxide is added 12.5 - 15 ml per 1 g of phenol sulfonate. The second iron ion affects as catalyst. After the second iron ions are activated, peroxide reacts with phenol sulfonate, so the second iron ions are dissolved before adding peroxide.
