Convenient, fast, boil the water has become a distant memory. However, over recent media coverage: a fountain from the mortgage company insider, as high as 99.3% of domestic heating lamps drinking fountains "all poisonous!" This news immediately drew an uproar. March 1, state management company announced the news is purely speculation, and not credible. Experts pointed out: The real fountain
Health
Is not hidden here.
Healthy drinking water shall meet the following requirements: non-pathogenic bacteria, heavy metals and hazardous chemicals; with appropriate
Minerals
And trace elements; with fresh and appropriate amount of dissolved oxygen; alkaline, the water molecules is small, strong activity. Experts pointed out: the regular manufacturers of water dispensers and
Bottled Water
Essential to meet this condition, "toxic" no set up.
Domestic consumers like to drink water, tea, and therefore attach great importance to the functions of heating water dispenser. Almost all the current domestic water dispenser heating lamps. Equipped with heat lamps to make drinking easier to use, but there are some problems, drinking fountains, "said toxic" is out accordingly. The Chinese Medical Foundation Health Professional Committee Li rehabilitation of drinking water were refuted, and gives some solutions to problems.
1, scaling: drinking fountains in the prone to scale, especially in areas with high water hardness. Appears mostly white precipitate carbonate. In fact, these salts to form a very stable compound there is no evidence that harmful. However, the presence of these substances affect the heat exchange efficiency, scaling serious, be a security risk. So drinking fountains in time scale removal.
II, "thousands of boiling water": the concept is not scientific. Drinking fountains, the heating temperature is generally 85 ~ 95 , not to the degree of boiling. However, the activity of long-term heating of the water will have an impact, so the longer the heating time, the worse the water activity, commonly known as "aging water", so long do not drink, they should turn off the power, in addition to power, but also to avoid loss of water activity.
Three fountains containing nitrite: As the water contain nitrate nitrogen, microbial contamination when the water dispenser serious, will lead nitrate into nitrite. WHO Drinking Water Directive provides that the indicators in the short term than 3mg / L, the infant methemoglobinemia occurs. From the current study to see there is not enough evidence to form nitrate and Minya
Cancer
Have a direct relationship.
4, bacteria: When the water dispenser in the water temperature exceeds 60 , the common microbes can kill. Above 80 , 10 to 20 minutes can kill Bacillus.
5, heating the material lead to harmful substances bile precipitation: Most of the regular production of materials used in heating lamps is
Stainless steel
Meet the relevant national health standards. Stainless steel is far higher than the temperature of boiling water resistance of the temperature, so there is no precipitation of harmful substances. Some counterfeit products using unhygienic materials, by hot water immersion, the harmful substances can be dissolved out, it will endanger health.
Director Lee said
Renaissance: Use water dispensers is the real health risks of secondary pollution. Each dispenser has a five part connected with the outside world, that the two leading, intakes, air port, discharge port. Secondary pollution of the drinking fountains are mainly carry large amounts of dust in the air micro-organisms, algae, etc. With the air into the dispenser, particularly the air port, outlet dead easy to form, in this large population of microorganisms, but also contaminated bottled water.
Abroad, use water dispensers have professional guidance, the need for regular cleaning. About 2 ~ 3 months cleaning time, cleaning professionals to find their own special little acid wash to use of cleaning
Disinfection
Liquid. In addition, the water dispenser the water consumed as soon as possible, especially in the summer, it is best used within a week.
Present, some enterprises for the shortcomings of the existing dispenser has been improved, such as bags of water, vacuum water dispenser, no guts, water dispenser, antibacterial materials, etc. (see related report March 9, 2006 The appliance version), these new drinking fountains will bring more healthy drinking water.
Backgrounder
2006 2 22, in the "China Drinking 'Water Health' Forum" on the production of gutless Cixi drinking fountains "Bridging the Jubilee," company executives announced: 99.3% of the gross domestic heating water dispenser market bile fountain "toxic", such as: pure drinking water constantly heated in the formation of "thousands of boiling water," scale as "additive", the heating lamps to create "nitrates", etc.. "Thousands of boiling water" will precipitate heavy metals and other toxic substances, long drink hazardous gastrointestinal health.
