We all know that hydrogen peroxide is generally used for medical, military, and daily disinfection. However, industrial hydrogen peroxide has one more purpose, which is to treat water pollution. However, hydrogen peroxide is an oxidant, which is specific in the treatment of water pollution. What's the use?
Since industrial hydrogen peroxide mainly contains hydroxide and sodium ions, the hydroxide can combine with many metal ions to form flocs or precipitates. For example, we all know that sewage contains metal ions such as aluminum ions or iron ions, strong acid salts and weak acid salts, etc., which react with hydroxide ions to produce flocs or insoluble precipitates. The flocculation principle is mainly to combine with the hydroxide radicals in the sewage to generate flocculent substances to achieve the flocculation effect. It can also remove excess acid radical ions in industrial sewage, such as Cl-(SO4)2-(PO4)3, etc. It is also often used to adjust the pH value, and the industrial hydrogen peroxide dosage is determined according to the PH situation.
Environmental protection can treat all kinds of harmful wastewater, including detoxification, deodorization and decolorization, and is especially suitable for the treatment of wastewater containing sulfur compounds, cyanides, and phenols. It can be used alone or in combination with ozone or ultraviolet rays. Purification of soil contaminated by leaked fuel oil or other organic matter with hydrogen peroxide can stimulate the re-growth of microorganisms, degrade pollutants, and treat waste gas containing NOx, SO2, H2S, etc., which can generate useful concentrated nitric acid and Concentrated sulfuric acid. Hydrogen peroxide can also improve the ability of biochemical methods to treat wastewater and prevent sludge from swelling. When the activated carbon used in the treatment of waste water and waste gas has expired, it can be regenerated with hydrogen peroxide.
