%X 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...
