| 摘 要： | 目的]研究非均相Fenton试剂降解苯酚废水的最优条件。方法]以活性炭作为载体,制备非均相的Fenton试剂(载铁活性炭与H2O2构成),通过催化剂投加量、pH、反应时间、H2O2∶Fe3+4个因素在5个水平下的正交试验,探讨了降解模拟苯酚废水的最优条件。结果]催化剂投加量为25 mg/L、pH为4、反应时间为80 min、H2O2∶Fe3+为11.1∶5时,模拟废水中苯酚的去除率较高,达到97.7%。结论]该研究为实际的苯酚废水处理提供了理论依据。 |

| Abstract: | Objective] The research aimed to study optimal condition of the phenol wastewater degradation by heterogeneous Fenton reagent.Method] Activated carbon as carrier,heterogeneous Fenton reagent which was composed of activated carbon containing iron and H2O2 was prepared.By the orthographical experiment of catalyst dose,pH,reaction time and H2O2∶ Fe3+ under 5 levels,optimal condition of the phenol wastewater degradation was discussed.Result] When catalyst dose was 25 mg/L,pH was 4,H2O2∶ Fe3+ was 11.1∶ 5,removal rate of the phenol in simulated wastewater reached 97.7% and was the highest.Conclusion] The research provided theoretical basis for actual phenol wastewater treatment. |
