| 摘 要： | 通过正交实验和单因素实验探索了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,各影响因素的作用大小顺序是:p H反应温度H2O2投加量反应时间Fe SO4·7H2O投加量;最佳氧化反应条件为:p H=3.5,反应温度为20℃,H2O2投加量为12 m L·L-1,反应时间为30min,Fe SO4·7H2O投加量为450 mg·L-1,此时废水中苯酚的去除率为89.26%,残余苯酚含量为11.76 mg·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。

| Abstract: | Removal of phenol in petroleum refining industry wastewater by Fenton reagent oxidation was examined. The optimal operating conditions were determined by orthogonal experiments and single factor experiments.The ex-periment results indicated that the order of effects was pH〉reaction temperature〉H2 O2 dosage 〉reaction time〉FeSO4 7H2O dosage.After 30min,the removal rate of phenol in petroleum refining industry wastewater reaches 89.26% and the residual phenol in wastewater is 11.76 mg·L^-1 when pH value is 3.5,temperature is 20 ℃, H2 O2 and FeSO4 dosage is 12 mL·L^-1 and 450mg/L,respectively.So it is a very effective way to treat petroleum refining industry wastewater containing phenol using Fenton method. |
