摘　　要：采用混凝-热固化-铁屑微电解的组合工艺处理高浓度水性油墨印花废水。结果表明,混凝剂NS-1的投加量在22.8 g/L左右,混凝后50℃以上热固化可使固液充分分离,废水COD去除率可达到87%;混凝后废水微电解p H为4,铁屑用量约为50%(w/w),停留时间为60 min时,废水COD去除率可达到83%;废水总体COD去除率可达90.3%。Combined process of coagulation-thermocuring-micro electrolysis of scrap iron was used in the treatment of water-based ink printing wastewater.The result showed that when the concentration of NS-1 was controlled at 22.8 g/L,the solid-liquid mixture could be separated by thermocuring when the heating temperature was above 50 ℃ after coagulation,and the removal rate of COD in wastewater could reach 87%; When the pH of wastewater was 4.0 by micro electrolysis after coagulation,dosage of ferric filings was 50%（w/w）,and reaction time was 60 min,the removal rate of COD in the wastewater could reach 83%.The overall removal rate of COD reached 90.3%.
