Uv协同Fenton氧化法对模拟青霉素废水的处理研究

Study on Treatment of Penicillin Wastewater by Uv/Fenton Oxidation Process

采用Uv/Fenton试剂氧化法对模拟青霉素废水进行降解研究。探讨了反应初始p H值、反应温度、反应时间、过氧化氢的用量以及过氧化氢和铁离子浓度比等影响因素对青霉素废水COD去除率的影响。实验结果表明,当废水的初始p H值为5.0,Fe2+/H2O2浓度比为1:20,过氧化氢投加量为0.3%,反应时间为30 min,紫外光照射波长为185 nm的条件下,青霉素废水的COD去除率最高可以达到91%。

The treatment of penicillin wastewater by Uv/Fenton reagent oxidation method was studied. Effect of initial pH value, reaction temperature, reaction time, hydrogen peroxide amount, concentration ratio of hydrogen peroxide to iron ion on the removal rate of COD was investigated. The experiment results indicated that when the initial pH of wastewater was 5.0, the concentration ratio of Fe^2＋ to H2O2 was 1：20, hydrogen peroxide dosage was 0.3%, reaction time was 30 min and the radiation wavelength was 185 nm,the COD removal rate of penicillin wastewater reached to 91%.
