摘　　要：近年来高铁酸钾(K_(2)FeO_(4))作为一种绿色水处理剂在原水预处理中发挥着重要作用。K_(2)FeO_(4)可以有效地去除水中各种有机及无机污染物,并且不会产生二次污染,污染物的去除效果与药剂投加量、pH、反应时间等因素有关。K_(2)FeO_(4)具有选择性氧化以及不稳定等不足,因此,发展了K_(2)FeO_(4)的强化技术与联用技术。结合近几年国内外的研究现状,分析了K_(2)FeO_(4)联用技术与强化技术的优势与局限性,其中Fe(Ⅲ)与K_(2)FeO_(4)作用明显,有效提高污染物去除率的同时减少了水处理过程中K_(2)FeO_(4)的用量,大幅降低了处理成本,应用前景广阔。In recent years,potassium ferrate(K_(2)FeO_(4))plays an important role in raw water pretreatment as a green water treatment agent.K_(2)FeO_(4)can effectively remove various organic and inorganic pollutants in water without secondary pollution.The removal effect of pollutants is related to the dosage of chemicals,pH,reaction time and other factors.K_(2)FeO_(4)has the disadvantages of selective oxidation and instability,so the enhanced and combined technology of K_(2)FeO_(4)has been developed.Combining with the research status at home and abroad in recent years,the advantages and limitations of K_(2)FeO_(4)combined technology and enhanced technology are analyzed.Among them,the combined effect of Fe(Ⅲ)and K_(2)FeO_(4)is obvious effect,which can effectively improve the pollutant removal rate and reduce the dosage of K_(2)FeO_(4)in water treatment process,greatly reduce the treatment cost,and have a broad application prospect.
