Background In the technical field of modern water treatment, the ferrate pre-oxidation process is an important means for removing pollutants such as organic matters, heavy metals, microorganisms and the like in water by virtue of the strong oxidizing property and flocculation property of the ferrate pre-oxidation process. Ferrate can be used for rapidly oxidizing and decomposing organic pollutants difficult to degrade, and ferric hydroxide which is a reduction product of ferrate can be used as a flocculating agent to effectively promote sedimentation of suspended particles in water. However, ferrate has extremely active chemical properties in aqueous solution, poor stability, and is extremely easily decomposed due to the influence of factors such as pH value, temperature, impurities and the like of a reaction system, so that the oxidation capacity and flocculation effect of the ferrate are greatly reduced, medicament waste is caused, and stable treatment effect is difficult to ensure.
