Abstract: To address the recalcitrant organic compounds in ink industrial wastewater and identify efficient pretreatment processes and conditions,this study investigates the degradation characteristics of UV/persulfate oxidation technology through parameter screening tests based on wastewater composition. The effects of critical operational parameters—including potassium persulfate （K2S2O8） dosage,reaction temperature,and duration—on treatment outcomes are systematically examined. Optimal process conditions are subsequently determined via single-factor and orthogonal combination experiments.

Key words: UV/persulfate oxidation technology, ink industrial wastewater, pretreatment, process condition, CODcr removal rate
