Water is the source of life, without water, there is no birth of life and human reproduction. However, with the rapid development of the economy, water pollution is becoming more and more serious.
Nowadays, what kind of water to drink and whether to drink safe water have become more and more important issues.
According to the World Health Organization, 80% of the world's diseases are caused by unsafe water and poor environmental health conditions, of which more than 50 diseases are caused by poor drinking water quality.
Of the 243 "cancer villages" on the mainland, 64 of them are directly caused by water pollution, and people are paying more and more attention to the safety of drinking water.
The emergence of water dispensers not only facilitates people's drinking water, but also improves the quality of drinking water. In many homes, almost every home is equipped with a water dispenser, and in many public places, such as hospitals, schools, offices, restaurants, etc., the water dispenser can be said to be a must-have appliance.
However, if the water dispenser neglects cleaning, there will be a very big health hazard. According to surveys, 43% of households have never cleaned a water dispenser, and even if they have, they have only done a simple scrub.
Experts warn that the water dispenser is not clean for a long time, becoming a "hotbed of bacteria", and the water storage gall bladder in the machine will breed a large number of bacterial viruses, deposit dirt, produce heavy metals, and even breed red worms.
What you drink every day may be "sewage" and "bacterial water", do you really dare to drink such water with confidence?
How dirty is the water dispenser?
Originally, the water dispenser was purchased to facilitate the drinking of clean and assured water, but if it was ignored or improperly cleaned, the water dispenser would cause secondary pollution of the water source. So where does the source of pollution come from?
We know that the water dispenser operates according to the principle of air pressure, and the "pressure difference" water is generated by entering the chassis with the help of outside air. Every time we take a glass of water, the corresponding volume of air enters the bucket, which leaves an opportunity for the bacteria and viruses to take advantage of.
Flying insects, dust, fine particles, microorganisms, etc. in the air may enter the inside of the water dispenser through the air, causing secondary pollution of drinking water.
In addition, due to production conditions or technical limitations, bottled water will inevitably contain certain microorganisms when barreled, and minerals in mineral water will form scale on the surface of the element after heating.
Although these scales themselves have little impact on human health, the long-term, large-scale accumulation and unscrammed water dispenser liner has become a "hotbed" for bacterial growth.
CCTV has also reported that if the water dispenser is used for a long time, its storage bile, waterway, outlet and other places are easy to deposit dirt, resulting in a large number of bacteria breeding. The water dispenser neglects cleanliness, and the hygiene situation is very worrying.
Someone did an experiment, selected a 5-day bottled water, and used two water dispensers for experiments, one is brand new and one takes 3 years. In order to ensure the rigor of the experiment, the water dispenser was sterilized in all aspects in advance.
Then I put the bottled water on the water dispenser and let it sit for 6 days, and the result was a big surprise! The total number of bacteria in both buckets of water is greater than 1000/ml.
It should be known that the mainland's "Drinking Water Standards" stipulate that the total number of bacteria in every 100ml of drinking water shall not exceed 100, and the water placed in the water dispenser for a few days in the experiment is far from meeting the national drinking water standards.
Next, the experimenters tested the hot water bacteria boiled in the water dispenser, and the experimental results showed that although the types of bacteria in the boiled hot water were reduced compared with cold water, the total number of bacteria was not significantly reduced.
In the United States, there was a trial to sample toilet water from a public water dispenser and a toilet, and the results were even more surprising, the water in the water dispenser was even dirtier than the water in the toilet!
I don't know how often everyone's water dispenser is cleaned? Half a year or a year? Or never cleaned? Take a look at the inside of the water dispenser that has not been cleaned for half a year, the hygiene level is comparable to the toilet!
Improper use of water dispensers may lead to an increase in hundreds or thousands of bacteria in drinking water in a short period of time, and what you drink every day may be "sewage".
Be wary of water dispensers becoming "sewage machines"
The water dispenser is not sealed, we will have a small amount of old water left in the water dispenser when changing water, causing cross-contamination, the longer the time, the more bacteria on the water dispenser.
According to the test of the relevant environmental health monitoring department, if the water dispenser is not cleaned for 3 months, it will multiply a large number of bacteria and become a toxic "additive". People drink water with excessive bacteria, which may cause problems such as diarrhea, which will continue to erode their health in the long run.
In daily life, many people just replace the upper drinking bucket, and rarely or completely clean the inner tank of the water dispenser, so that not only can not drink "assured water", the water dispenser becomes a "sewage machine", and may even be sick from the mouth.
Experts suggest that in order to prevent the secondary pollution and scale formation of the water dispenser, it should be cleaned and disinfected every 3 months. During the use of the water dispenser, if you smell the water odor, or find that there is white or yellow scale in the sink when changing the water, it is recommended to clean according to the instructions.
If the water flow of the water dispenser becomes smaller and the time of boiling the water is prolonged, it may be the "cleaning signal" issued by the water dispenser.
In addition, after the bottled water is opened, it is best to drink within 7 days, and the bottled water in a static state is easy to breed bacteria after a long time.
Water dispenser is not equal to the "water purifier", if not often cleaned, it will become a "health killer" in your life, if you can not do regular cleaning and disinfection of the water dispenser, it is recommended that you do not use the water dispenser, directly use bottled water to boil water to drink.
