Abstract

In this study we use NaClO to produce HClO in the acidic solution for replacing H₂O₂ in the Fenton reagent to treat naphthol wastewater. The results show that we can treat-naphthol wastewater more effectively. The pH,[Fe²⁺] and the dosage of NaClO play a significant role in the Fe²⁺/HClO oxidation process. With the irradiation of medium-pressure mercury lamp, after 60 min photod egradation in the Fe²⁺/HClO system, the COD_Cr removal of-naphthol wastewater is 60.8% while the COD_Cr removal is only 45.1% without illumination.【Key Words】： sodium hypochloritephotodegradation-naphtholwastewater treat ment
