  • 摘要: 为了深度处理印染废水生化出水，使其达到工业回用要求，利用微波活化过硫酸钾产生具有强氧化性的硫酸根自由基·SO4-，降解印染废水生化出水中的有机污染物。考察了硫酸亚铁的投加量，过硫酸钾的浓度及pH的影响，并通过对比实验讨论了微波活化作用效果。结果表明，过硫酸钾微波组合能够有效地去除生化出水中的TOC和色度。对于某印染废水生化出水，处理效果在pH=10时最好，当过硫酸钾浓度为14 g/L时，TOC去除率达57.60%，脱色率为98.28%。研究结果表明，过硫酸钾微波组合对于印染废水的深度处理效果良好，有较好的应用前景。
    Abstract: Microwave activated potassium persulfate was exploited to treat the biological effluent of dyeing wastewater for water recycling in industry, as microwave can promote the decomposition of potassium persulfate to produce a powerful oxidant—sulfate free radical (·SO4-). It can destroy organic compounds in biological effluent of dyeing wastewater. The effects of ferrous sulfate concentration, K2S2O8 concentration and pH were investigated and the role of microwave activation was discussed. Experimental results show that the combination of potassium persulfate and microwave can effectively remove TOC and chroma. At potassium persulfate dosage of 14 g/L and pH 10, TOC removal is 57.60% and chroma removal is 98.28%. It is concluded that the combination of potassium persulfate and microwave may have a potential in the tertiary treatment of dyeing wastewater in industry due to its effectiveness.
