Fenton氧化处理炼化废水中苯酚的实验研究

Study on treatment of phenol in petroleum refining industry wastewater by fenton reagent

通过单因素实验探索了Fenton氧化炼化废水中苯酚的最佳工艺条件。实验结果表明,Fenton试剂处理苯酚废水时,最佳氧化反应条件为:pH=3.5,反应温度为20℃,H2O2投加量为12mL·L-1,反应时间为30min,FeSO4·7H2O投加量为600mg·L-1。因此用Fenton氧化法处理含苯酚废水是一种非常有效的方法。

Removal of phenol in petroleum refining industry wastewater by Fenton reagent oxidation was examined.The optimal operating conditions were determined by single factor experiments.The experiment results indicated that after 30min,the removal rate of phenol in petroleum refining industry wastewater rises to the top when pH value is 3.5,temperature is 20 ℃ ,H2O2 and FeSO4dosage is 12 mL . L^-1 and 600mg/L,respectively.So it is a very effective way to treat petroleum refining industry wastewater containing phenol using Fenton method.
