芬顿-粉煤灰协同处理有机实验废水

Disposing of Organic Experiments Wastewater by the Ways of Oxidation of Fenton Reagent and Fly Ash

摘要: 利用芬顿试剂的强氧化性和改性粉煤灰良好的吸附性,协同处理有机实验废水.主要考察了过氧化氢、硫酸亚铁、改性剂用量及吸附条件对处理效果的影响.结果表明:当过氧化氢用量为25 g/L、硫酸亚铁用量为4.5 g/L、改性剂氧化钙浓度为30 g/L、吸附温度为35℃、pH值为5、振荡时间为35 min时,有机废水CODCr去除率可达90.5%.

Abstract: The strong oxidative fenton reaction and modified fly ash with good adsorptivity were utilized in organic wastewater treatment.The effects of hydrogen peroxide,ferrous sulfate,dosage of modified catalyst and adsorption conditions were investigated.The results indicate that the organic wastewater CODCr removal rate can reach 90.5% with hydrogen peroxide of 25 g/L,ferrous sulfate of 4.5 g/L,calcium oxide of 30 g/L,at the adsorption temperature of 35 ℃,pH = 5 and oscillation time of 35 min.
