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.
