中文摘要：

介绍了近年来强氧化剂高铁酸钾在水处理中的应用成果及现状。高铁酸钾可有效地去除水中微生物、无机以及有机污染物，污染物去除效果与高铁酸钾投加量、反应pH、反应时间等因素有关。由于高铁酸钾具有氧化选择性及不稳定等缺点，有必要发展高铁酸钾联用技术，结合国内外的研究进展，分析了高铁酸钾联用技术的协同作用，其中高铁酸钾与光催化协同作用明显，可大幅提高光催化效率，加速污染物的去除，在环境治理领域有着广阔的应用前景。

英文摘要：

The research achievements and status of applying potassium ferrate to improve water quality are reviewed. Potassium ferrate can remove microbes, inorganic and organic pollutants effectively from water, and the removal efficiency is affected by ferrate dosage, solution pH, reaction time and other factors. Due to the selective oxidation and instability of potassium ferrate,it is necessary to develop the hyphenated techniques by combination of potassium ferrate and other water treatment techniques. The synergetie effects of above-mentioned hyphenated techniques are discussed based on domestic and overseas research progress. Obvious synergistic effect between potassium ferrate and photocatalysis （e.g. UV-TiO2） can be observed and has been widely applied in removing various pollutants.
