| 摘 要： | 采用Fenton氧化对焦化废水进行了深度处理。结果表明：Fenton氧化反应迅速,可迅速降低焦化废水生化出水的COD;H2O2和Fe2＋的投加量对Fenton氧化具有明显的影响;pH=3时反应体系具有最佳的COD去除效果。在H2O2投加量为1.994 mL/L,FeSO4.7H2O投加量为0.543 g/L,pH=3,温度为35℃的条件下,反应出水COD低于100 mg/L,去除率可达72.7%;Fenton氧化可有效去除生化出水中的难降解有机物。实验结果表明Fenton氧化是深度处理焦化废水的有效工艺。

| Abstract: | Advanced treatment of coking wastewater by Fenton oxidation process was studied.The results show that the COD can be removed quickly by Fenton oxidation,dosages of H2O2 and Fe2＋ can obviously affect the COD removal efficiency.The best COD removal efficiency can be gotten when pH=3.When dosages of H2O2 and Fe2＋ are 1.994 mL/L and 0.543 g/L respectively,the COD can be removed to less than 100 mg/L at pH=3 and 35 ℃,and the COD removal efficiency is up to 72.7%.Fenton oxidation process can effectively remove refractory organic compounds in coking wastewater.Therefore,Fenton oxidation process is an effective means for advanced treatment of coking wastewater. |
