摘要
运用Fenton试剂对含活性染料废水进行混凝前的预处理。通过预处理前后废水吸光度曲线的变化 ,探讨其作用机理。试验表明 ,直接混凝法处理含活性染料废水时 ,脱色率仅为 10 %～ 30 % ,吸光度曲线几乎不变。当Fenton试剂对其预处理后 ,吸光度曲线中的吸收峰消失 ,继续混凝处理 ,脱色率可达 96 .77%。
Active dyestuff bearing Wastewater is pre-treated with fenton reagent before its flocculation, and the action mechanism is discussed by observing the change of absorbancy curve. Experiment shows the rate of decoloration only ranges from 10% to 30%, and absorbancy curve doesn't vary when active dyestuff bearing wastewater is directly treated with flocculation. After pre-treating with fenton reagent, the absorption peak of absorbancy curve disappears. Then treating with flocculation, the rate of decoloration can be as high as 96.77%.
