But, you don't know. The water dispenser hose has been used for a long time, and the white scales produced by the oxidation corrosion of the hose are easy to cause secondary pollution of drinking water. In addition, according to the monitoring of the national environmental health monitoring department, if the water in the drinking fountain is not cleaned for 3 months, it will contain viruses and bacteria (including enterovirus, Escherichia coli phage, Salmonella, Staphylococcus, Vibrio parahaemolyticus, etc. ). In addition, in order to prevent the water dispenser liner from burning in the case of water shortage, the water storage container stores about 100ml of water. Because even if the bucket is changed, it will not be recycled, so bacteria are easy to multiply. If you are not careful, red nematodes and red worms will play together.
Drinking this water for a long time may cause diarrhea, vomiting and many common gastrointestinal diseases, which will have a certain impact on human health. Experts say that the working principle of the water dispenser is to use air pressure, and at the same time, the same amount of air enters the inside of the water dispenser. Even clean air contains about 4000 bacterial colonies per square meter. Due to poor indoor air circulation, it carries a lot of pollutants such as dust. This kind of air will accumulate and multiply with the passage of time, and the number of bacteria will reach an alarming level, causing secondary pollution of water quality and endangering human health. When it comes to bottled water dispensers, it is necessary to mention bottled water.
The quality of bottled water in the market is worrying. It is said that some of the water in the bucket is natural mineral water, but after investigation, it is found that there is garbage around the water source and some is tap water. The problem of bottled water is constant, and the water quality is difficult to guarantee. On the other hand, some manufacturers of small and medium-sized buckets do not seriously disinfect the recycled empty buckets, but simply rinse them with tap water. The bacteria in the bucket multiply. If this bucket is used to hold water, it may be polluted even if it is clean. Some buckets that have been used for more than time have become a "paradise" for bacterial reproduction.
On the other hand, some "black barrels" are made of polymers in industrial wastes. This is an organic pollutant, which easily penetrates into water molecules and brings carcinogenicity to human body. People who drink the water in the "black barrel" will not feel it immediately, but like chronic poisoning, the harm will appear many years later.
