Pre-oxidizing agent for strengthening stability of ferrate and application of pre-oxidizing agent

The invention discloses a pre-oxidizing agent for strengthening the stability of ferrate, and relates to the technical field of water treatment. The pre-oxidizing agent comprises ferrate and hypochlorite in a certain molar ratio, when the pre-oxidizing agent is added for water treatment, hypochlorite reacts with hydrogen peroxide generated in the ferrate decomposition process, hydrogen peroxide is consumed, accordingly, the self-decomposition reaction of the ferrate is inhibited to a certain extent, and the water treatment effect is improved. The hypochlorite ions can effectively improve the stability of the ferrate, and meanwhile, the hypochlorite ions can decompose suspended matters in water, change the surface characteristics of the suspended matters, reduce the absolute Zeta potential of the suspended matters and enhance the coagulation effect on the suspended matters and micro-plastics in the water in cooperation with the ferrate. 本发明公开了一种强化高铁酸盐稳定性的预氧化剂，涉及水处理技术领域。本发明所述预氧化剂中包括具有一定摩尔比的高铁酸盐和次氯酸盐，在投加所述预氧化剂进行
