Characteristics and application of chlorine dioxide disinfectant. Must chlorine dioxide disinfectant be prepared and used now

2024-05-17

Chlorine dioxide has a strong ability to absorb and penetrate the microbial cell wall, which can effectively oxidize the enzyme containing sulfhydryl group in the cell

Chlorine dioxide disinfectant is internationally recognized as a highly effective disinfectant, which can kill all microorganisms, including bacterial propagules, bacterial spores, fungi, mycobacteria and viruses, and these bacteria will not produce drug resistance.
Chlorine dioxide has a strong ability to absorb and penetrate the microbial cell wall, which can effectively oxidize the enzyme containing sulfhydryl group in the cell, and can also quickly inhibit the synthesis of microbial protein to destroy the characteristics of microbial chlorine dioxide disinfectant
1, efficient, powerful in common disinfectants, the same time to the same bactericidal effect required ClO2 concentration is the lowest. The concentration of ClO2 required to kill heterotrophic bacteria is only 1/2 of Cl2. The effect of ClO2 on killing Escherichia coli in surface water was more than 5 times higher than that of Cl2. Chlorine dioxide has a stronger killing effect on spores than chlorine.
2, fast, long-lasting chlorine dioxide dissolved in water, basically no chemical reaction with water, also does not exist in the state of dimerization or polymerization. Its diffusion speed and penetration ability in water are faster than chlorine, especially at low concentrations. When the concentration of bacteria is 105~106/mL, ClO2 of 0.5ppm can kill more than 99% of heterotrophic bacteria after 5 minutes. However, the sterilization rate of 0.5ppm Cl2 can only reach 75%. Tests show that the sterilization rate of 0.5ppm ClO2 to heterotrophic bacteria remains above 99% within 12 hours, and the sterilization rate decreases to 86.3 only after 24 hours of action.

3, broad-spectrum, sterilization ClO2 is a broad-spectrum disinfectant, all the pathogenic microorganisms spread through the water body have a good killing effect. In addition to killing general bacteria, chlorine dioxide has a good killing effect on spores, viruses, heterotrophic bacteria, iron bacteria, sulfate reduction and fungi, and is not easy to produce drug resistance, especially for typhoid fever, hepatitis A, hepatitis B, polio and HIV also have good killing and inhibiting effects. ClO2 was more effective than O3 and Cl2 in inactivating the virus. Low doses of chlorine dioxide also have a strong helminticidal effect.
4, non-toxic, non-stimulating acute oral toxicity test shows that chlorine dioxide disinfection and sterilization agent is the actual non-toxic grade products, cumulative test conclusion for weak accumulation of substances. The water body disinfected with it will not damage the oral mucosa, skin membrane and scalp, and it is absolutely safe in acute toxicity and genetic toxicology.
5. Safe and extensive chlorine dioxide does not interact with organic matter in water to generate carcinogens such as trihalomethane, and has no carcinogenic, teratogenic and mutagenic effects on higher animal cells, sperm and chromosomes. The effect of ClO2 on reducing anion, cation and oxidation is mainly detoxification (H2S, SO32-, CN-, Mn2 ), and the oxidative degradation of organic matter is mainly based on small molecular compounds with oxygen-containing groups. Up to now, these products have been proved to be non-toxic, and the dosage of ClO2 is very low, so disinfection with ClO2 is very safe and has no residual toxicity. Its safety is rated AI by the World Health Organization (WHO). Application range of chlorine dioxide disinfectant
1. Disinfection of life, drinking and tap water in various occasions.
2. Sterilization and disinfection of restaurants, hotels, families, stalls, tableware and sanitary facilities and air environment disinfection.
3. Final sterilization and disinfection of equipment, pipes and containers in food and beverage factories and fermentation industries.
4. Final sterilization and disinfection of equipment, pipelines and containers in dairy plants, slaughter plants and fermentation industries.
5. Sterilization and disinfection treatment of hospital sewage.
6. Sterilization and disinfection of swimming pool circulating water and bath water.
7, medical, health, clinical equipment disinfection, sterilization, deodorization and mildew treatment.
8, families, hotels, restaurants, fruits and vegetables, fish food preservation and final washing disinfection and sanitary ware disinfection.
9, high-rise building water supply secondary disinfection treatment.
10, the preparation of various oral disinfectant, deodorant and wound cleaning liquid, etc.
11. Clean, disinfect and deodorize the ambient air in public places, refrigerators, cold storage, offices, dormitories, carriages and air conditioning and ventilation systems. It can also be used for sterilization and disinfection of sick homes, wards and patient items.
12. Prevention and treatment of fish and shrimp diseases, disinfection and oxygenation of pool water, killing of clam hepatitis A virus and sterilization, disinfection and preservation of mushroom production, etc., to achieve the effects of disease prevention, production increase and quality improvement.
13, fish and shrimp processing in the process of disinfection control of miscellaneous bacteria, Escherichia coli and other pollution and preservation.
14. Disinfection of animal, poultry and livestock farms and drinking water, and disinfection of silkworm cocoon breeding utensils.
15. Sterilization and deodorization in reclaimed water reuse.
16, flour and a variety of food bleach.
17, paper, printing and dyeing industry bleaching agent.
18, industrial circulating cooling water algae sterilization treatment.
19. Chlorine dioxide is used as a plugging remover in water injection oil recovery and is fully capable of oxidizing organic biomass and any polymer residues that plug rock formations. Does chlorine dioxide disinfectant have to be prepared for current use? Chlorine dioxide disinfectant is generally prepared for current use. According to actual needs, chlorine dioxide disinfectant: liquid activator is activated for 10 minutes at a ratio of 10:1, diluted to an appropriate concentration, and then disinfected. During preparation, chlorine dioxide disinfectant must be put first, then liquid activator must be put, and finally mixed into stock solution. Since the effective disinfection time is only 4-6 hours, it is generally required to prepare for current use.
