Embodiment 1
[0030] First, take 0.01 kg of sodium pyrophosphate, 19.0 kg of glacial acetic acid, and 61.2 kg of reverse osmosis water in a liquid mixing tank, start stirring at room temperature and stir for 30 minutes to obtain an inert substance solution.
[0031] Put 3.5kg of 40% peracetic acid and 17.3kg of 30% hydrogen peroxide into the above-mentioned inert substance liquid mixing tank and stir at 25°C-35°C for 2 hours to obtain a disinfectant mother liquor, which is passed through three stages Type microporous membrane filtration (the pore size of the filter membrane is 1.2μm-0.45μm-0.22μm, and the order of flow through the filter membrane pore size is from large to small) and then filled to obtain the final product.
Embodiment 2
[0033] Take 0.02kg of sodium pyrophosphate, 20.0kg of glacial acetic acid, and 56.0kg of reverse osmosis water in a liquid mixing tank, start stirring at room temperature and stir for 30 minutes to obtain an inert substance solution.
[0034] Put 4.0kg of 40% peracetic acid and 20.0kg of 30% hydrogen peroxide into the above-mentioned liquid mixing tank and stir at 25°C-35°C for 2.5 hours to obtain a disinfectant mother liquor. Pore filter membrane filtration (the pore size of the filter membrane is 1.2μm-0.45μm-0.22μm, and the order of flow through the filter membrane pore size is from large to small) and then filled to obtain the final product.
Embodiment 3
[0036] Take 0.03kg of sodium pyrophosphate, 22.0kg of glacial acetic acid, and 56.0kg of reverse osmosis water in a liquid mixing tank, start stirring at room temperature and stir for 30 minutes to obtain an inert substance solution.
[0037] Put 4.6kg of 40% peracetic acid and 20.0kg of 30% hydrogen peroxide into the above-mentioned liquid mixing tank and stir at 25°C-35°C for 2 hours to obtain a disinfectant mother liquor. Pore filter membrane filtration (the pore size of the filter membrane is 1.2μm-0.45μm-0.22μm, and the order of flow through the filter membrane pore size is from large to small) and then filled to obtain the final product.
