摘要
利用高铁酸钾处理经过改性粉煤灰混凝后的造纸废水,探讨了改性粉煤灰和高铁酸钾联合处理造纸废水工艺;研究结果表明,在改性粉煤灰用量35g/100mL,并投加25mg/L高铁酸钾时,对造纸废水处理效果最优,上清液再用10mg/L的高铁酸钾处理,此为最佳工艺条件,出水水质达到造纸用水标准。
Potassium ferrate （K2FeO4）was used to treat papermaking wastewater that had pretreated by modified fly ash,which formed the new water treatment process of modified fly ash and K2FeO4. The dosage of modified fly ash was 35g/100L and the doping dosage of K2FeO4 was 25mg/L,under which the treatment effect of papermaking wastewater was optimal. The supernatant liquid was treated by the 10mg/L amount of K2FeO4,which is the best procedure.The effluent quality reached water standard of paper industry.
