超声波强化Fenton试剂深度处理山梨酸废水的研究

采用超声强化Fenton(Fe2++H2O2)试剂,耦合氧化深度处理山梨酸废水。考察了超声功率、反应时间、反应温度、pH值、试剂投加量对CODCr去除率的影响。结果表明:在超声频率40kHz,超声功率400W,反应时间40min、反应温度60℃、pH值3.0、H2O2浓度0.22mol/L、Fe2+浓度0.04mol/L时,CODCr去除率达到95%以上。与单独使用Fenton试剂法相比,该方法反应时间短、反应温度低、试剂投加量小、CODCr去除率高。

Experimental Study on Treatment of Sorbic Acid Wastewater by Ultrasound and Fenton Reagent Oxidation

The ultrasonic wave -Fenton （Fe^2＋＋H2O2） reagent was used to treat sorbic acid wastewater. Effects of ultrasonic power, reaction time, temperature, pH value, the weight of catalyst Fe and hydrogen peroxide, on CODCr removal efficiency were experimentally studied. The result shows that when ultrasonic power was 400 W, reaction time was 40 min, the reaction temperature was 60 ℃, pH Value was 3.0, concentrations of H2O2 and Fe^2＋ were 0.22 mol·L^-1 and 0.04 mol·L^-1, the removal ratio of CODCr was more than 95%.
