The tap water at home can only be drunk when boiled, which in itself is wrong. Here's why:
1.After the tap water is boiled, although the bacteria are killed, the corpses of the bacteria remain in the water, which becomes the source of human fever, which is called "thermogenic matter" in medicine. 2.
In the traditional precipitation filtration process of chlorine disinfection, chlorine is synthesized with putrescine in water to form chloroform, which is recognized as a carcinogen in the world. Water is boiled to between 90 and 100 degrees Celsius, and chloroform is 3 to 4 times more than raw water. Fish will die if they are raised directly from tap water without precipitation, but they are larger than humans and fish, and the toxicity of chlorine to the human body will not be immediately apparent.
When people take a bath, they absorb hundreds of times more chlorine than when they drink water. 3.After the water is boiled, it loses a lot of oxygen, and the flowers will wither when watering the flowers with cool boiled water, which is the relationship that the flowers cannot absorb oxygen from the water.
And 60% 70% of the body's body weight is water, infants and young children can reach more than 70, and the metabolism of cells is completed by the oxygen in the water. Therefore, drinking boiled water is not conducive to the supply of oxygen to the human body, and the cells of the human body are deformed due to lack of oxygen, which is also one of the causes of cancer.
People should drink filtered water.
Bottled water does not need to be boiled to drink, because bottled water has gone through the production process of filtration, but if it becomes pure water after reverse osmosis, it is recommended to only use it for travel, and do not drink it on weekdays.
-
The water at home is tap water, which itself contains a large number of germs, which must be boiled and killed before drinking, and bottled water is pure water that has been filtered and treated multiple times, so it can be drunk directly, but now there are many bottled water I don't know if it has really been treated, such as a dollar of mineral water is not very safe!
-
Because the tap water at home has not been deeply disinfected, there will be bacteria and even parasites, so it must be boiled before drinking, and bottled water has been sterilized, but now bottled water is not as safe as we imagined.
-
Because the bottled water has been sterilized.

Boiled tap water can be drunk. Tap water is domestic water that has been filtered and disinfected and other simple treatments to meet the national drinking water quality standards. When boiling water, when the water is close to 100, the lid of the kettle should be opened to let some of the residual volatile organic compounds in the water volatilize, and then turn off the fire after 2 3 minutes after boiling.
Tap water refers to the water produced by the tap water treatment plant after purification and disinfection that meets the corresponding standards for people's life and production.
Domestic water is mainly absorbed from rivers, lakes, groundwater and surface water through the water intake pumping station of the water plant, which is treated by the waterworks in accordance with the relevant health standards for domestic drinking water, through precipitation, disinfection, filtration and other technological processes, and finally transported to various users through the water distribution pumping station.

Generally, tap water can be boiled and drunk directly.
Tap water can be drunk as long as it is boiled. As long as the tap water quality is clear and there is no other miscellaneous smell, it can be drunk directly, but if the water quality is not clear and there is a particularly unpleasant odor, it is not recommended to boil it in this case. After the water is boiled, continue to boil for 2 to 3 minutes and then turn off the heat, which can kill the microorganisms inside and can have a good sterilization effect.
Under normal circumstances, the tap water is generally disinfected to meet the drinking water standard, and the tap water has a sterilization effect after boiling, in this case it can be drunk, but if the tap water has not been disinfected or the tap water is relatively turbid and placed for a long time, it is best not to drink it in this case, and there may be certain problems with water quality.
Precautions for boiling tap water for drinking
Boil the tap water for another three minutes, and boil the water yourself to drink, which is convenient and cost-effective. If you want to boil the water to taste better and the water quality is safer, don't boil the tap water immediately after taking it out, and let it sit for a while. Open the lid when the water is about to boil, and wait for two or three minutes after the water boils before turning off the fire, so that the harmful substances in the water can effectively volatilize away.
The national standard stipulates that when chlorine-containing disinfectants are added to tap water, the residual chlorine content of the tap water must be greater than or equal to milligrams of liters when the tap water reaches the end of the pipe network, which is a measure to ensure that bacteria and microorganisms do not exceed the standard.
However, the standard for residual chlorine in drinking water is not to exceed milligrams, and one professor pointed out, "This requires boiling the water to eliminate the residual chlorine in the water." In addition, you can leave the water for a few minutes before boiling it, which will reduce residual chlorine. Household water purifiers can also be used to filter the water. ”

Boiled tap water can be drunk and the water is clean. The main difference between pure water and boiled water is that boiled water is tap water that is boiled at 100 degrees and then cooled down, because it only destroys a small amount of harmful substances, so that it still retains a lot of microorganisms and minerals. Pure water is filtered several times, not only is there no toxic substances, but also the minerals that are beneficial to the human body are eliminated.
Tap water disinfection is made of chlorine, chlorine is a toxic gas, can kill bacteria, but its solubility in the water will decrease with the increase of temperature, that is, the higher the temperature of the water, the less chlorine it contains, so the tap water should be boiled to drink, it is best not to drink raw, and the sediment in the water is because of the gum added when the water plant first treated the water, which can precipitate the impurities in the water.
-
Yes, that's usually the case.
However, the water quality may be relatively bad in recent years, so you can filter it first, and then burn it, which needs to be filtered.
Or you can buy bottled mineral water and boil it to drink.
-
Tap water is up to the standard of drinking water, in the process of the water plant to the user, will add bleaching powder and other agents for disinfection, raw water is best not to drink directly, after boiling disinfection can be directly drunk.
-
Yes, a lot of tap water in China has reached the level of direct drinking in foreign countries, but the pipes cannot be as safe as theirs.
-
As long as your tap water fully meets the national drinking water standards, you can drink it directly after boiling! In fact, there is no need to drink pure water all the time, from the perspective of human health, drinking water lacks the necessary trace elements of the human body, and regular drinking is not conducive to the body's metabolism.
-
Yes. Civilian tap water, whether it is deep underground water or shallow water taken from the surface, is poured into the water supply system by the water supply department after strict inspection and treatment, and generally speaking, it is tap water that can be drunk with confidence.
-
Of course!
At least more than 60% of households in China use tap water to boil and drink! Our country's tap water has reached the standard, so you can drink it with confidence!
-
Water quality has been polluted in recent years. There are a lot of impurities. It's best to press a water purifier. Drink and eat with confidence. It is guaranteed for the body, and the safety factor is higher. Filtration and purification can improve the quality of the water.
-
Of course, tap water can be boiled and drunk directly, which meets the national drinking water standard.
-
Tap water boils, it needs to be slightly cooler before drinking, otherwise it will burn your mouth.
-
Of course, tap water should be boiled and drunk, and it will be enough to boil for half a minute.
-
Can you boil tap water and drink it directly?
-
Isn't it common to boil tap water without a water purifier?!
-
Can you boil tap water and drink it directly?
-
In general, tap water can be boiled to drink, and high temperatures can kill some bacteria and viruses in the water. However, if the tap water is polluted by the environment, the heavy metals and some harmful substances in the water will not disappear because the water is boiled, so it is best to pass through the water purifier and then boil the water to drink.
The tap water at home has a lot of impurities and bacteria. Boiling tap water can kill most bacteria, but there are still a lot of impurities remaining, and long-term drinking has a great impact on human health. Tap water contains a large amount of impurities and sediments, because most of the domestic water pipeline network uses galvanized iron pipes, and the lead content of the material is too high, resulting in high lead content in the water quality.
In addition, the water pipes are in disrepair and damaged, which may also cause secondary pollution to the quality of the tap water.
-
It must be boiled and drunk, especially if there is a filtered gas in it, and now the tap water has scale, it must be filtered before drinking, or the scale must be floated away and then drunk.
-
Freshly boiled tap water is 100 degrees Celsius, so if you don't want to get burned, you should not drink it.
Hazards of tap water:
It does not play a role in balancing the pH of the human body.
The main disinfectant in the production process of tap water is bleaching powder, i.e. chloride ions. As early as 1974, American and Dutch scholars discovered that chloroform compounds are produced in the chlorination process of drinking water, and suspected that one of these compounds could cause cancer in humans.
More importantly, because the tap water is sent to our homes through the pipeline after being treated by the source eggplant, there is serious secondary pollution such as excessive heavy metals in metal pipes, which will have a great impact on the human body.
-
Because our tap water is chlorinated, chlorine combines with residual organic matter in the water to produce halogenated hydrocarbons, chloroform and other carcinogenic compounds. Chloroform is also a kind of carcinogenic compound, so boiled water cannot be drunk directly, and it becomes warm boiled water after the temperature drops.
The correct way to boil and drink water should be to connect the tap water first, and then leave it for a while before boiling; Then open the lid of the kettle when the water is about to boil, and finally wait for 3 minutes after the water is boiled before turning off the fire, which can reduce the chlorine content in the water to the safe drinking standard, which is real boiling water.
-
Of course, you can drink the tap water when it is boiled.
The water you drink meets the national drinking water quality standards, so don't worry too much about the hazards.
Tap water is surface water or well water that has been simply treated by filtration and disinfection, and the water quality is the lowest among the three, but rest assured, there is no problem to drink after boiling, but be careful not to boil it repeatedly. The biggest advantage is that it is cheap.
Pure water is much better (such as stuffy liquid fruit, you buy a qualified product), generally after reverse osmosis treatment, the bacteria and viruses in it are gone, of course, there is no rock, minerals are generally left. The drinking water in foreign countries and the direct drinking water in high-end residential areas in China are pure water treated by reverse osmosis. Although there are people on the market who attack purified water as bad for health, the fact is that most of the minerals needed by the human body are obtained through food, so there is no problem in drinking pure water.
Because the treatment process is relatively complex, it is much higher than tap water.
It's so hot, you have to wait until it's cold before you can drink it.
There are two possibilities for individuals:
1.Mineral water contains small amounts of minerals, i.e. metal ions. >>>More
The bacteria in the water will be killed in the boiling water, and some alkaline substances in the water will also be turned into corresponding carbonates.
Boiled tap water and boiled mineral water both have their own advantages and disadvantages, so one cannot generalize about which one is better. Tap water usually comes from the water supply system of a household or public facility, and after a series of treatments and disinfections, it is considered safe drinking water. Tap water contains a certain amount of minerals and trace elements, which may be released into the water after boiling, which has certain benefits for the body. >>>More
Which is healthier cannot be generalized.
1. Bottled water is generally divided into pure water and mineral water. >>>More
