The invention discloses an oxidation-reduction method for rapidly achieving regeneration of an ammonium ion sieve, aims at the problems that a conventional ion sieve regeneration method is single, relatively high in material solution loss rate in the regeneration process and low in regeneration efficiency, and aims to provide a new idea for ion sieve regeneration. The oxidation-reduction method is not limited by mechanisms of ion exchange regeneration, instead, the ammonium ion sieve is regenerated by virtue of an oxidation-reduction mechanism; the problem of a high material solution rate caused by a conventional acid regeneration ion sieve can be overcome; due to the weak oxidation property of nitrite, ammonium ions can be oxidized and a manganese dioxide framework is barely affected, and thus the solution loss rate of manganese in the secondary ammonium ion sieve regeneration process can be less than 0.03%; and an efficient ion sieve regeneration method is provided, the conventional nitric acid regeneration time is as long as 3 days, and by adopting the scheme of the invention, the regeneration rate can be up to 95% or greater within 40 minutes.
