  • 摘要: 以粉煤灰联合微波-Fenton氧化工艺处理活性艳蓝KN-R生产废水,考察了粉煤灰投加量及吸附时间对处理效果的影响,并通过正交实验对微波-Fenton工艺参数进行了优化。实验结果表明,粉煤灰絮凝吸附与微波-Fenton氧化具有协同效应;在粉煤灰投加量为40 g/L,搅拌吸附时间为20 min,滤液pH值为4,Fe2+和H2O2投加量分别为3.6 mmol/L和0.15 mol/L,微波功率为200 W,辐射反应时间为4 min的优化条件下,染料废水的处理效果最好,COD和色度的去除率分别达到90.90%和99.98%。
    Abstract: The influences of fly ash dosage and adsorption time on removal effect were studied, and the orthogonal experiments were carried out to optimize the microwave-Fenton process. The result shows that flocculation and adsorption of fly ash have cooperative effect with microwave-Fenton oxidation. The optimal operating conditions are as follows: the fly ash dosage of 40 g/L, adsorption time of 20 min, the filtrate pH value of 4, the Fe2+ dosage of 3.6 mmol/L and H2O2 dosage of 0.15 mol/L, microwave power of 200 W, radiation time of 4 min. Under these conditions, the COD and chromaticity removal rate could reach 90.90% and 99.98%, respectively.
