Embodiment 1
[0023] At room temperature, add 250ml of aqueous hydrogen peroxide solution with a concentration of 30% by mass into the reaction flask with stirring, and add 0.41g of sodium dihydrogen pyrophosphate, then add 337g of industrial anhydrous sodium sulfate, and stir to make the sodium sulfate fully Dissolve, then slowly add 68g of sodium chloride under stirring, react for 1h; the reaction mixture is crystallized at 0°C, filtered, the mother liquor is partially circulated, and the filter cake is dried to obtain 330g of sodium sulfate / hydrogen peroxide / sodium chloride ternary addition thing.
[0024] Add the sodium sulfate / hydrogen peroxide / sodium chloride ternary adduct to the rotating drum, control the temperature inside the drum to 100°C, make 3.3 chitosan into a 5% aqueous solution, and spray it on the moving sodium sulfate through the nozzle On the hydrogen peroxide / sodium chloride ternary adduct, after the water is evaporated, an aquaculture oxygenation and disinfection water...
Embodiment 2
[0026] At room temperature, add 250ml of aqueous hydrogen peroxide solution with a concentration of 30% by mass into a stirred reaction flask, add 4.1g of ethylenediaminetetraacetic acid diammonium, then add 638g of industrial anhydrous sodium sulfate, and stir to make sodium sulfate Fully dissolve, then slowly add 34g of sodium chloride under stirring, react for 1h, cool and crystallize, filter, partly circulate the mother liquor, and dry the filter cake to obtain 295g of sodium sulfate / hydrogen peroxide / sodium chloride ternary adduct.
[0027] Add the sodium sulfate / hydrogen peroxide / sodium chloride ternary adduct into the fluidized bed to make it in a fluidized state; make 0.05% aqueous solution of 2.95g chitosan, and spray it on the moving sulfuric acid through the nozzle Sodium / hydrogen peroxide / sodium chloride ternary adduct; after the water evaporates, an aquaculture oxygen-increasing and disinfecting water purifier product with an active oxygen content of 4.3% is obtain...
Embodiment 3
[0029] At room temperature, add 250ml of 50% mass percent hydrogen peroxide aqueous solution into a stirred reaction flask, add 3g of sodium dihydrogen pyrophosphate and 3g of ethylenediaminetetraacetic acid diammonium, and then add 500g of industrial anhydrous sulfuric acid Sodium, stir to fully dissolve sodium sulfate, then slowly add 50g sodium chloride under stirring, react for 2h; cool the reaction mixture to 10°C to crystallize, filter, partly circulate the mother liquor, and dry the filter cake to obtain 1120g sodium sulfate / peroxide Hydrogen / sodium chloride ternary adduct.
