Abstract

The invention relates to a system for treating BHP effluent. The system is characterized by comprising a BHP effluent storage tank, a BHP effluent diluter, a primary reactor, a primary stabilizing tank, a secondary reactor and a secondary stabilizing tank; all the components are successively connected through pipelines; the BHP effluent diluter is connected with a dilution water storage tank through the pipeline; the primary reactor is connected with a concentrated hydrochloric acid storage tank through the pipeline; the secondary reactor is also connected with a diluted hydrochloric acid storage tank through the pipeline. According to the invention, a two-step method is adopted for neutralizing the BHP effluent; the treating effect is excellent and the treated wastewater is high in degreeof purification; the temperature of the system is effectively controlled, the risk caused by hydrogen peroxide decomposition is reduced and the potential safety hazard is reduced; the treating systemhas high resistance to impact load, high system stability, and meanwhile, the design is reasonable and the structure is compact.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a purification system for BHP waste liquid. Background technique [0002] BHP solution, also known as alkaline hydrogen peroxide solution, is produced by the reaction of hydrogen peroxide and alkali metal salt (usually potassium hydroxide) solution, and is a main reaction substance used in the research of chemical oxygen-iodine lasers. BHP waste liquid mainly contains hydrogen peroxide, potassium hydroxide and potassium chloride. The liquid shows strong alkalinity (pH>14) and needs to be treated before it can be discharged. Traditional equipment neutralizes the acid in one go. But the acid-base neutralization reaction releases a lot of heat. The temperature of the over-reaction system will be too high, which will bring potential safety hazards. At the same time, hydrogen peroxide decomposes to produce oxygen after being heated. Especially when hydrogen peroxide is heate...
