【摘要】 近年来高铁酸钾（K₂FeO₄）作为一种绿色水处理剂在原水预处理中发挥着重要作用。K₂FeO₄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。K₂FeO₄具有选择性氧化以及不稳定等不足，因此，发展了K₂FeO₄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K₂FeO₄联用技术与强化技术的优势与局限性，其中Fe（Ⅲ）与K₂FeO₄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K₂FeO₄的用量，大幅降低了处理成本，应用前景广阔。更多还原

【Abstract】 In recent years, potassium ferrate（K₂FeO₄） plays an important role in raw water pretreatment as a green water treatment agent. K₂FeO₄ 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. K₂FeO₄ has the disadvantages of selective oxidation and instability, so the enhanced and combined technology of K₂FeO₄ has been developed. Combining with the research status at home and abroad in recent years, the advantages and limitations of K₂FeO₄ combined technology and enhanced technology are analyzed. Among them, the combined effect of Fe（Ⅲ） and K₂FeO₄ is obvious effect, which can effectively improve the pollutant removal rate and reduce the dosage of K₂FeO₄ in water treatment process, greatly reduce the treatment cost, and have a broad application prospect.更多还原
