First, the existence and source of pathogenic bacteria in hot spring water:
People often have a "automatic" disinfection theory of hot spring water: "The hot spring is a kind of flowing living water, and the sulfur component in the spring water has the function of disinfection and sterilization"... This is wrong. First, in addition to sulfur springs, there are many kinds of hot springs such as carbonate springs, salt springs, sodium bicarbonate springs, simple springs, etc., which do not have disinfection functions. Second, hot springs will be in the process of natural exile. Microorganisms include the presence of protozoa, algae, fungi, and bacteria, and hot spring pools may also cause pathogenic microorganisms and organic matter contamination due to human activities. The bath microbiological monitoring program recommended by the World Health Organization (WHO) includes fecal E. coli, E. coli, and Pseudomonas aeruginosa. If the content of fecal E. coli and E. coli is less than 1 cfu/100 ml, the water quality is good.
Since most of the domestic hot springs adopt continuous water changes and increase the frequency of bath cleaning, the hot spring water is cleaned. However, in this mode of operation, once the number of tourists is too large, or the sudden fecal contamination of the bath, consumers are immediately exposed to the high risk of infection of pathogenic microorganisms.
In addition to feces, the source of pathogenic microorganisms in hot springs may also come from the saliva, wounds and mucosal tissues of the human body. For example, a cold, sick or injured bather, his wound or mucosal tissue may release pathogens directly contaminating the hot spring pool water, and anyone who directly contacts these hot springs with pathogenic microorganisms may cause infection. In addition, some bacteria or protozoa can breed in the hot spring water, and also enter the human body through the respiratory or dermal tissues of the contact, causing disease. For example, the warm, humid and nutrient-rich environment of the hot springs is suitable for the breeding of Legionella, Pseudomonas aeruginosa and Amoeba. Such microorganisms often invade people who otherwise have other diseases or have a weak immune system.
Generally speaking, when the water temperature is between 31-36 ° C and the water is rich in organic matter, the bacteria can survive for a long time. The Legionnaires' disease in the city is mainly caused by humidification in air humidifiers, water storage systems, air conditioning systems, etc. Caused by Legionella in the environment.
In 2002, a large-scale Legionnaires' disease was reported in Japan. A total of 166 cases were caused by hot springs. The Japanese government survey showed that there are more than one-tenth of the hot springs with Legionella. Legionnaires' disease is a respiratory infection, that is, lobar pneumonia. Most of its pathogens are found in water vapor in public places such as baths and hot springs.
Second, the advantages of chlorine dioxide disinfection of hot spring water:
Under the influence of Japanese bathing culture, it is deeply feared that the use of sanitizers will destroy the unique properties of hot springs. Therefore, many hot springs believe that a large amount of fresh hot spring water or water change can be avoided under the conditions of abundant hot spring water sources. Bacteria breed, but do not take into account the bacterial contamination and proliferation caused by the original soup, raw water, soaking soup and air dust. However, those who lack the hot spring water source often adopt the method of circulating filtration heating because of the lack of spring water, but they do not consider that heating will cause biofilm formation in the pipeline and cause bacterial proliferation.
Chlorine dioxide is a chlorine-containing disinfectant, but it cannot be simply called “chlorine preparation”. It is a highly efficient oxidizing disinfectant with an oxidation capacity of 2.63 times that of chlorine. In actual use, the effect can be achieved. 10 times the chlorine preparation:
Chlorine dioxide has no "triple" effect and has a broad-spectrum antibacterial effect;
Chlorine dioxide can oxidize heavy metals such as iron and manganese to make it harmless;
Chlorine dioxide can play a certain role in suppressing excessive reduction of hydrogen sulfide to prevent excessive damage to the human body;
Chlorine dioxide can achieve good disinfection and sterilization effect in ph 2-10;
Chlorine dioxide has a degrading effect on ammonia nitrogen compounds, greatly reducing the hazards of various organic substances;
Under normal circumstances, the concentration of chlorine dioxide in the hot spring water reaches 0.8mg/l, which can maintain the use of one day. The disinfection methods such as ozone, hydrogen peroxide and ultraviolet rays are instantaneous and do not have the function of maintaining sterility. Therefore, chlorine dioxide is more advantageous in hot water disinfection than other disinfectants and common chlorine preparations, and is the preferred agent for hot spring disinfection.
Third, the use of chlorine dioxide in hot spring baths and product recommendations:
1. Product recommendation:
Product Name: One yuan chlorine dioxide disinfectant (granules)
Packing: 500g / bag, 1000g / bag, can be customized according to customer needs
Product Name: One yuan chlorine dioxide disinfectant (powder)
Packing: 500g / bag, 1000g / bag, can be customized according to customer needs
2, the use of:
Disinfecting object | Use concentration (mg/L) | Disinfection method |
| Hot spring water disinfection | 0.8 | Add after loop filtering |
