摘　　要：利用电芬顿-混凝协同处理印染废水。结果表明,pH值为4,电压6 V,反应时间25 min,支持电解质Na2SO4浓度2.0 g/L,FeSO4投加量200 mg/L,对印染废水的处理效果最佳,色度和COD的去除率可以达到99.9%和87.4%。此方法具有高效、去除效果好、经济适用等优点,在印染废水的处理领域具有广阔的应用前景。Electric Fenton-coagulation process has been used for the treatment of printing and dyeing wastewater. The results indicated the best condition： pH 4,electrolytic voltage 6 V,reaction time 25 min,Na2SO4 dosage 2. 0 g / L,FeSO4 dosage 200 mg / L. The highest chroma and COD removing rate reach99. 9% and 87. 4%. This method has the advantages of high efficiency,good removal effect,economy applicable in the field of printing and dyeing wastewater treatment has broad application prospects.
