preparation example Construction
[0053] The preparation method of the acidic oxidation potential sterilizing water capable of finely adjusting the pH value of the present invention comprises the following steps:
[0054] (1) Provide A unit that can generate hydrogen ions;
[0055] (2) Provide unit B containing available chlorine;
[0056] (3) Provide a C unit with a pH adjusting effect;
[0057] (4) When in use, unit A, unit B and unit C are mixed to obtain an acidic strong oxidizing solution. The pH value of the acidic strong oxidizing solution is between 2-7, its redox potential is 800-1300mV, and its available chlorine The content is 30-3000mg / L.
[0058] The pH of the acidic reagent A unit is less than 7, preferably pH=0-6, more preferably pH=0-5, more preferably pH=0-4, more preferably pH=0-3, most preferably pH=2 -3.
[0059]The A units may be selected from inorganic or organic acids or salts of strong acids and weak bases or precursors of acidic substances. The inorganic acid may be selected from ...
example 1
[0066] Example 1, A and B units are mixed and then mixed with C unit
[0067] After the A and B units are mixed, an overacid acidic oxidation potential solution E is formed, and E is then diluted by a specific volume of C units to generate a specific acidic oxidation potential solution D. Among them, regardless of whether the mixing mode of A and B units is directional or non-directional, the whole is an acidic oxidation potential solution from peracid balance to specific acidity, forming various forms of available chlorine.
example 2
[0068] Example 2, A and C units are mixed and then mixed with B unit
[0069] After the A and C units are mixed, an acidic diluent F is formed, and F is then mixed with the basic B unit to generate a specific acidic oxidation potential solution D. Among them, the volume of unit A can be controlled to reduce the acidity of unit A, thereby effectively reducing the generation of chlorine gas.

Abstract
The invention relates to the field of sterilization and disinfection and particularly relates to acid oxidation potential sterilization water with fine control on a pH value and a preparation method of the acid oxidation potential sterilization water. The preparation method comprises the following steps of: (1), providing an A unit capable of generating hydrogen ions; (2), proving a B unit containing active chlorine; (3), providing a C unit with a pH value control function; and (4), mixing the A unit, the B unit and the C unit in use to obtain an acid solution with strong oxidizing property, wherein the pH value of the acid solution with strong oxidizing property ranges from 2 to 7, the oxidation-reduction potential of the acid solution with strong oxidizing property ranges from 800mV to 1300mV, and the active chlorine content of the acid solution with strong oxidizing property ranges from 30mg / L to 3000mg / L. Compared with the prior art, the preparation method ensures that the sterilization water has the properties of acid oxidation potential water, can be used for accurately controlling the pH value of the sterilization water through regulating the volume of the sterilization water, and especially can be used for accurately controlling the pH value of the sterilization water in a subacidity range of 5-7.
Description
technical field [0001] The invention relates to the field of sterilization and disinfection, in particular to an acidic oxidation potential sterilizing water capable of finely adjusting the pH value and a preparation method thereof. Background technique [0002] In the prior art, a preparation method of acidic oxidation potential sterilizing water is disclosed, comprising the following steps: (1) providing A unit capable of generating hydrogen ions; (2) providing B unit containing available chlorine; (3) using , A unit is mixed with B unit to obtain an acidic strong oxidizing solution. Wherein, the A unit is an acidic solution; the reagent of the B unit is one or more of liquid chlorine, hypochlorite, double salt of hypochlorite, chlorite or hypochlorous acid precursor A combination, the hypochlorous acid precursor refers to a chlorine-containing substance that can react with an acid to generate hypochlorous acid. In order to reduce the generation of chlorine gas, the acid...
