Study on mining water treatment process by modified fly ash and K2FeO4
改性粉煤灰和高铁酸钾联合处理矿井水的研究

In this paper,a mining water treatment process was proposed by using modified fly ash as coagulant and postteated by potassium ferrate(K_2FeO_4) oxidation.The results showed that the residual turbidity of treated water was decreased from 53.18 to 25.42 NTU at the dosage of 50 g,/L after fly ash was modified by H_2SO_4,while the COD_(Mn) removal efficiency increased from 29%to 50%.When modified fly ash mixed with potassium ferrate were used to treat mining water at the dosage of 50 g/L and 5 mg/L respectivel...
