FIELD: chemistry.
SUBSTANCE: group of inventions relates to a multi-step method of treating peroxide solutions for reuse or recycling. Treatment of a peroxide solution includes collecting a primary peroxide solution which includes hydrogen peroxide or peroxy acid and hydrogen peroxide; adding a hydrogen peroxide-reducing enzyme to the primary peroxide solution; adding a peroxide compound reducing agent to the primary peroxide solution, where there is at least 0.1 part of peroxide compounds broken down by the enzyme per 1 part of peroxide compounds broken down by the reducing agent. A treated peroxide solution is then obtained as a result of adding an enzyme and a reducing agent.
EFFECT: use of the group of inventions efficiently reduces the content of peroxide compounds in peroxide solutions without significantly increasing the content of overall dissolved dry substances.
