摘要
对EDTA催化芬顿试剂反应处理杀虫双废水的效果进行了研究。考察了EDTA的浓度、过氧化氢投加量、硫酸铁投加量、pH值、反应时间等因素对处理效果的影响,确定了实验的最佳条件:EDTA的浓度为0.10mmol/L,过氧化氢(30%)的投加量为15.00mL/L,硫酸亚铁的投加量为1.50g/L,pH值4,反应时间为50min,反应温度为50℃,此时CODCr去除率为80.05%。
It studied on the treatment effect of using Fenton＇s strong oxidizing agent and EDTA＇s catalytic ability in the synergistic processing bisultap wastewater under different operating conditions. It mainly investigated some important factors on the treatment effect, such as the concentration of EDTA, the dosage of hydrogen peroxide（30%）, the dosage of ferrous sulfate, pH, reaction time and reaction temperature. At last, the best conditions were obtained under the following： the concentration of EDTA was 0.10 mmol/L, the dosage of hydrogen peroxide（30%） was 15.00 mL/L, the dosage of ferrous sulfate was 1.50 g/L, the pH was 4, reaction time was 50 min, reaction temperature was 50 ℃. The results showed that the removal rate of wastewater CODcr reached 80.05%.
