摘要

以NaClO在酸性水溶液中生成的HClO代替Fenton试剂中的氧化剂H₂O₂,在Fe²⁺的作用下对β-萘酚模拟废水进行处理,结果表明:使用HClO代替H_{2_O2}处理β-萘酚模拟废水能够取得更好的效果;废水pH、FeSO₄和NaClO的投加量对降解效果有很大影响;光照可以促进β-萘酚的降解,60min后CODCr去除率可达60.8%,而同样条件下无光照时CODCr去除率仅为45.1%。

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
