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H2O2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%。
In this study we use NaClO to produce HClO in the acidic solution for r eplacing H2O2 in the Fenton reagent to treat -naphthol wastewater. The resul ts show that we can treat -naphthol wastewater more effectively. The pH, and the dosage of NaClO play a significant role in the Fe2+/HClO oxidation pr ocess. With the irradiation of medium-pressure mercury lamp, after 60 min photod egradation in the Fe2+/HClO system, the CODCr removal of -naphthol wastewate r is 60.8% while the CODCr removal is only 45.1% without illumination.
