Current domestic application status of chlorine dioxide disinfectant

1. Water treatment industry

1. Drinking water disinfection

Almost all water plants in the United States and Western Europe have replaced chlorine with chlorine dioxide for disinfection, which is characterized by good taste, safety and non-toxicity, which can reduce toxic substances and do not produce carcinogens, and is convenient to use, safe and low comprehensive cost. Due to the late start of chlorine dioxide production in China and the failure to form industrialization, chlorine dioxide is far behind developed countries in the application of water treatment in China. At present, with the introduction of relevant support policies of the Ministry of Construction, water plants around the country will inevitably eliminate the application of traditional disinfectants in drinking water, which will bring opportunities for the rapid promotion of chlorine dioxide in the drinking water industry. It is foreseeable that for China, whose quality of life is rapidly improving with 1.4 billion people, chlorine dioxide is the best substitute as a drinking water disinfectant, and its consumption will be huge.

2. In terms of industrial circulating cooling water treatment

The pH value of industrial circulating water is alkaline, and the sterilization ability of chlorine disinfectants is greatly reduced by the pH value in the application, and the long-term application produces drug resistance, not only the dosage is getting larger and larger, but also several disinfectants need to be used alternately, even so, it is difficult to achieve the ideal effect. Chlorine dioxide, on the other hand, is an enzyme that destroys microbial cells by its strong oxidation ability, preventing the synthesis process of proteins, thereby breaking them down and killing them. Therefore, chlorine dioxide is not resistant to pesticides and has a broad spectrum of bactericidal bacteria. For example, after the final test of the North China Pharmaceutical General Factory, the current annual consumption has exceeded 60 tons. Due to the small dosage, long maintenance time, no resistance, and low disinfection cost, it overcomes the troubles caused by the alternating use of several disinfectants and the shortcomings of environmental pollution, and the economic and social benefits are significant.

3. Application in swimming pool water treatment

As a national fitness sport, swimming has become the people's favorite sport with the improvement of people's living standards. The quality of water quality is the most concerned problem for swimmers, chlorine disinfectants in the disinfection of swimming pool water at the same time, produce a great pungent odor, especially in indoor swimming pools, swimmers often have red eyes, yellow hair; The use of chlorine dioxide to disinfect swimming pool water does not produce irritating odors, and removes odors, purifies water quality, and has an oxygenation effect, so that the indoor air of the swimming pool is fresh and the pool water is blue.

Second, the health care industry

used for disinfection and sterilization of medical equipment; dental sterilization and oral gargling; ophthalmic irrigation solution, wound irrigation, disinfection of infectious disease sources; Hospitals, hotels, restaurants, vehicles, ships, toilets, funeral homes and other places of environmental disinfection, deodorization, and can make the air fresh, and its comprehensive performance is better than other disinfectants.

3. Food industry

Sterilization and disinfection of food water, purified water and mineral water, sterilization and disinfection of food processing equipment and pipelines, sterilization and disinfection of packaging bags, bottles and caps of food and beverages; halogen, aquatic products, beverages and other anti-corrosion preservation; removal of fruits, vegetables and residual pesticides; Rapid sterilization and preservation; Deodorization and disinfection of food refrigerators, freezers, etc. The United States, Japan, Canada and other countries have a very common application of stable chlorine dioxide in this regard, and China's food hygiene department has also formulated the "Stable Chlorine Dioxide Food Additive Standard", which is currently being vigorously promoted and applied. For example, a meat processing plant in Guangdong Province uses more than 40 tons of chlorine dioxide for meat disinfection and workshop environment and equipment disinfection every year. Fourth, the animal husbandry industry

In recent years, the application of chlorine dioxide in the livestock and poultry breeding industry has been developed rapidly, and many provincial and municipal livestock and poultry disease prevention and control departments in China have successively used chlorine dioxide as a control and prevention of the sterilization and disinfection of the air and ground environment of livestock and poultry houses.

5. Aquaculture industry

As the fourth generation of aquaculture disinfectant, chlorine dioxide can not only greatly reduce the number of pathogenic microorganisms in the water, but also do not damage plankton, disinfect and oxygenate the water body, and have significant curative effects on hemorrhagic septicaemia, rotten gills, red skin, enteritis, water mildew and solomycosis, virus disease of shrimp. In recent years, it has been rapidly popularized in coastal aquaculture areas such as Hainan, Guangdong, Shandong, and Hebei, and has gradually penetrated into the inland freshwater aquaculture areas.

6. Vegetable planting industry

The application of chlorine dioxide in the crop planting industry was first popularized in Japan. Because it effectively kills all kinds of molds and viruses at the same time, there is no toxic substance residue, and it is highly respected in today's vigorous promotion of green health food. In China's Hebei Gaoyi, Shandong Shouguang and other vegetable and mushroom planting bases, have achieved successful experience and good economic benefits, especially in the disease-prone greenhouse vegetable and mushroom planting industry is gradually popularized, and the market demand is huge.

7. Other industries

As a multifunctional industrial and civil chemical product, chlorine dioxide has many applications. Such as in the household application: can be used to gargle, wash vegetables, fruits, underwear underwear, towels, toilets, refrigerator disinfection, etc., with the improvement of people's living standards, household special disinfectants are the potential market for chlorine dioxide. The secondary water supply disinfection of urban high-rise buildings is also a large market, such as bleach in the paper industry, petroleum water injection treatment, and daily chemical industry. ​​​​​​​
