1. Secondary pollution of bottled water is inevitable

Experts say that the "secondary pollution" common in bottled water is inevitable. Without exception, water is delivered by bicycles or tricycles. The entire water delivery process is affected by time, climate, environment, and personnel quality, so the possibility of "secondary pollution" is extremely high. There is also a common problem of "thousand boiling water" in bottled water. Bottled water is repeatedly heated in the water dispenser, which will form "thousand boiling water". It looks clean, but in fact it is a concentrated liquid of harmful substances such as heavy metals and arsenic compounds.

2. Overtime service buckets become a paradise for bacteria to breed

According to industry insiders, according to regulations, each bucket must be scrapped after being used 100 times. Experts say scrap barrels are often a breeding ground for bacteria. Some small and medium-sized bottled water manufacturers do not carefully disinfect the recycled empty barrels, but simply rinse them in tap water before use, resulting in a large number of bacteria in the barrels. With this kind of bottled water, no matter how good the water is, it will definitely be destroyed. Contaminated. "Black barrels" have not completely withdrawn from the market. The phenomenon of overtime service of water barrels is serious. Waste barrels that should be eliminated are still used in large quantities, which causes great pollution to bottled water.

3. Black-hearted water and black-hearted buckets: endangering health and causing endless poisons

"Black-hearted water" refers to bottled water that is filled directly with tap water by unscrupulous vendors. The high molecular polymers in industrial waste will leak out in the water environment. This is an organic pollutant that can easily cause cancer in the human body. People who drink the water from the "black heart bucket" will not feel it immediately, but like chronic poisoning, the harm will show up after many years. Long-term drinking of these low-quality bottled water can also damage the human digestive system and nervous system, cause dizziness, stomach pain, and even cause cancer.

4. The problem of "stagnant water"

The storage period of bottled water should not exceed 2 days, because drinking aged water will affect health. It is understood that water ages very quickly. Water molecules have a long chain structure. If water is not subject to frequent strong impacts, this chain structure will continue to expand and extend, turning into aged water, commonly known as "dead water". There are few people in the unit office, and a bucket of water takes 7 to 10 days. This kind of "stagnant water" is very harmful to health! In recent years, the incidence of esophageal cancer and gastric cancer has been increasing in many areas, and experts believe it is related to drinking "stagnant water" that has been stored for a long time.

5. The water dispenser is contaminated by bacteria and the water cannot be boiled

The special electric structure of the water dispenser makes it very easy to be contaminated by bacteria. First of all, the heating temperature of the water dispenser is 86 degrees, the cooling temperature is 5 degrees, which cannot kill bacteria at all but is very suitable for bacterial reproduction. Over time, bacteria form a bacterial film, which is difficult to remove, just like forming a bacterial stronghold. After hygienic water passes through such a water dispenser, It carries tens of thousands of bacteria. The heating temperature of the drinking water machine is 86 degrees. The water cannot be boiled and is not suitable for making tea.
