Embodiment 1

[0017] Weigh 21 kg of anhydrous zinc sulfate, dry and fully pulverize into fine powder, then divide into three equal parts for later use. Mix 7 kg of anhydrous zinc sulfate powder and 10 kg of sodium chlorite in an airtight container, and dry in a dryer at 115°C for 20 minutes to make the first component; 7 kg of zinc sulfate water powder and 14 kg of sodium persulfate were mixed evenly in a closed container, and dried in a dryer at 120 ° C for 15 minutes to make the second component; another part of zinc sulfate anhydrous powder 7 kg 1 kg and 6.5 kg of maleic acid are mixed evenly in a closed container, and dried in a dryer at 110°C for 20 minutes to make the third component; add the third component to the second component, and mix well Then add it to the first component, and pack it in separate bags with moisture-proof materials after mixing.

Embodiment 2

[0019] Weigh 20 kg of anhydrous zinc sulfate, dry and fully pulverize into fine powder, then divide into two equal parts for later use. Mix 10 kg of anhydrous zinc sulfate powder and 10 kg of sodium chlorite in a closed container, and dry in a dryer at 115°C for 20 minutes to make the first component; Mix 10 kg of anhydrous zinc sulfate powder with 13.5 kg of sodium persulfate and 7.5 kg of malic acid in a closed container, and dry in a dryer at 110°C for 20 minutes to make the second component; Add it to the first component, mix evenly, then dry it in a dryer at 120°C for 10 minutes, and pack it in separate bags with moisture-proof materials.

Embodiment 3

[0021] Weigh 18 kg of anhydrous sodium sulfate, dry and fully pulverize into fine powder, then divide into three equal parts for later use. Mix 6 kg of anhydrous sodium sulfate powder and 10 kg of sodium chlorite in a closed container, and dry in a dryer at 115°C for 20 minutes to make the first component; Mix 6 kg of sodium sulfate water powder and 15 kg of sodium persulfate in a closed container, and dry in a dryer at 120 ° C for 15 minutes to make the second component; another part of sodium sulfate anhydrous powder 6 1 kg and 6.5 kg of maleic acid are mixed evenly in a closed container, and dried in a dryer at 110°C for 20 minutes to make the third component; add the third component to the second component, and mix well Then add it to the first component, and pack it in separate bags with moisture-proof materials after mixing.

Abstract

The invention relates to a solid monadic chlorine dioxide disinfectant, which is characterized in that the disinfectant is configured by sodium chlorite, sodium persulfate, solid organic acid (such as a citric acid, a maleic acid or a malic acid) and a solid filling agent (such as anhydrous sodium sulfate, anhydrous zinc sulfate or anhydrous aluminium sulphate), wherein, the mass ratio of the sodium chlorite and the sodium persulfate is 100:125 to 100:140; the mass ratio of the sodium chlorite and the solid organic acid is 100:64 to 100:106; the mass ratio of the sodium chlorite and the solid filling agent is 100:158 to 100:380. The disinfectant has simple and convenient configuring technology and stability and safety of the product; therefore, the invention can be directly used for water disinfection or making chlorine dioxide disinfectant by dissolving in suitable water.

Description

technical field [0001] The invention relates to a chlorine dioxide disinfectant, in particular to a solid monobasic chlorine dioxide disinfectant and a preparation method thereof. It belongs to the technical field of environmental protection. Background technique [0002] Chlorine dioxide has multiple functions such as sterilization, anti-corrosion, fresh-keeping, and deodorization, and is internationally recognized as a fourth-generation disinfectant with excellent performance. As we all know, liquid chlorine has been used in the early water disinfection treatment, and the chloroform (carcinogen) in the treatment product is extremely harmful to the human body. In 1983, the US National Environmental Protection Agency proposed that the content of chloroform in drinking water should not exceed 0.01mg / L, and recommended chlorine dioxide as one of the most suitable technologies for controlling chloroform in water, so that it has been widely used in drinking water. Since then,...
