Is it better to drink tap water boiled by the school, or to buy mineral water?

Of course, it is better to drink mineral water. There are two reasons for this:

1) Although the use of chlorine to purify the water in the production process of tap water can kill harmful substances such as pathogenic microorganisms, the addition of chlorine itself can cause new chemical pollution. Chlorine can be combined with organic matter in water to form chloroform, which is a carcinogen. At the same time, chlorine also destroys nutrients and can easily lead to heart disease.

2) In the pipe network of tap water, long-distance pipeline transportation, old and rusty pipelines, urban high-rise water tanks and building reservoirs are not clean or used all year round without disinfection, which can cause secondary pollution. Secondary pollution causes bacteria, viruses and algae to multiply, plus the original chlorine and chloride, rust, heavy metals, radioactive substances, make the water turbid, have a peculiar smell, and its harm is endless.

Therefore, tap water is not standard drinking water. In a variety of increasingly polluted environments, people must have strict standards for drinking water from their bodies. The original face of reducing water, drinking mineral water is in line with the needs of the human body, and drinking mineral water is more beneficial to people's health than drinking boiled water.

Because boiled water loses too much oxygen, drinking boiled water is not conducive to supplying oxygen to the human body.

If you have the conditions, you can buy mineral water to boil, and if you don't have the conditions, you will order it......

When I was in college, every dormitory had a water dispenser because we used water every day to pump groundwater ......But even if it's water from the water dispenser, the water is quite cheap, I remember that 200+ can buy 35 buckets, with an average of 1 bucket of water ......

It's not bad if the school has **, at least the water is absolutely safe, the difference is whether it's good or not, it's just good to get used to it.

Tap water Drinking too much mineral water is not good for your health

It depends on the water quality of your school, if the water quality is good, the boiled water is better than mineral water.

Summary. Dear, hello, I'm glad to serve you to answer Oh, boiled tap water or mineral water, both of which are better, in fact, whether it is boiled tap water or mineral water is better, can supplement some elements needed by the human body. However, it is not recommended to drink only mineral water for a long time, because mineral water is rich in mineral components, and excessive intake may cause adverse effects on the body, such as affecting the body's acid-base balance and gastric juice secretion.

Dear, hello, I'm happy to serve you to answer Oh, boil tap water or mineral water, this envy is better for both, in fact, whether it is boiled tap water or mineral water is better, can supplement some elements needed by the human body. However, it is not recommended to drink only mineral water for a long time, because the mineral water is rich in minerals, and excessive intake may cause adverse effects on the body, such as affecting the body's acid-base balance and gastric fluid secretion.

The tap water comes from rivers and lakes, groundwater and surface water, and after being purified and disinfected by the water plant, this stall is then transported to every household through underground water pipelines. Normally, as long as the tap water meets the requirements of the sanitary standards, long-term drinking will not cause health damage. However, it is recommended to boil and drink because the water pipeline may be rusty and cause secondary pollution of tap water.

The source of mineral water comes from the groundwater that flows through certain rocks in the deep underground layer, and the trace elements contained in it are the components of Xunshan shouted that the human body needs, and drinking it in moderation is good for the body. However, it is not recommended to boil and drink, because most of the mineral elements in boiled mineral water are lost in scale, and there is little nutritional value left. Therefore, if you want to drink the spring water of the mine, you can drink the bottled water directly, and there is no need to boil it.

OK.

Generally, tap water can be boiled before drinking, tap water is sterilized, if your local tap water is too dirty, you can filter it before boiling it to drink. But just boiled water, don't drink it immediately, wait more than 3 minutes, let the chlorine go before drinking.

Disinfection method. Tap water disinfection mostly uses chlorination.

Chlorine is soluble in water and reacts with water to form hypochlorous acid and hydrochloric acid, and hypochlorous acid plays a major role in the entire disinfection process. For inorganic substances that produce odors, it can completely oxidize and disinfect them, and for living natural substances such as algae and bacteria, it can penetrate the cell wall and oxidize its enzyme system (enzymes are biological catalysts) to make it inactive, so that the life activities of bacteria are hindered and die.

Hypochlorous acid itself is close to neutral, easy to approach the bacterial body and shows a good sterilization effect, hypochlorite ion also has a certain disinfection effect, but it is negatively charged and difficult to approach the bacterial body (the bacterial body has a negative charge), so compared with hypochlorous acid, its sterilization effect is much worse, so the chlorine disinfection effect is better than the use of bleach disinfection.

Hello dear, I am glad to answer for you: which is better to boil mineral water or tap water Answer: Hello dear:

Boiling tap water is good 1After the tap water is boiled, the metal content will not decrease, and the hardness will not decrease; 2.Tap water vs. purified water:

Tap water: The water from the source is transported to each household through the water pipeline network through the processes of flocculation, sedimentation, filtration, chlorine disinfection and other processes. Tap water, known as safe water.

Its advantages are: it contains a certain amount of minerals and trace elements, contains oxygen; The disadvantage is that the residual chlorine contained in the water for disinfection will be combined with organic matter to produce highly toxic substances acting on genes, various bacteria and viruses, and secondary pollution of the water pipeline network.

But boiling water is stagnant because of the loss of oxygen. Purified water: This is actually water that is not suitable for ordinary people to drink.

Because in addition to the absence of some minerals and trace elements that can only be ingested from drinking water, pure water is still acidic water, and regular drinking will cause the human body to be acidic, and acidic constitution is the source of all diseases (there are many on the Internet).

Boiling water is good because it comes.

After purified water, there are no more minerals in it. When people drink water, they can't replenish the human body like they drink tap water.

DAO some essential minerals, long-term life like this, is not good for your health, although it is troublesome to boil tap water to drink, but the tap water that has been sterilized at high temperature does not contain bacteria, and it also retains minerals that are useful to the human body. This is what the teacher taught when I was in school. hoho So when you go to the supermarket to buy water to drink, you also have to buy mineral water, and 8 you have to buy purified water.

It's not good to drink it often. Long-term use of pure water, is not good for the body, although it seems that pure water is very convenient to use, but from the point of view of the process of pure water, because it has been purified many times, although pure, but at the same time of filtering impurities, the minerals that are beneficial to the human body in the water are also filtered out, so that when people drink water, they can not supplement some essential minerals of the human body like drinking tap water, and living like this for a long time is not good for their health, so it is recommended that you still use the most ordinary method - Boiling tap water to drink, although it is a little troublesome, but the tap water that has been sterilized at high temperature does not contain bacteria, and it also retains useful minerals for the human body, which is good for the body. However, sometimes there are more guests at home, and it is definitely too late and not enough to boil water, so pure water is still a good choice.

Actually, it's all the same. Drink it selectively. However, the source people feel that the tap water is boiled and bai is better than mineral waterAlso look at the place to come ,, if.

If you are in a big city, then it is recommended that you and mineral water, generally the disinfectant water in big cities will be heavier, if you are in a rural or township where there is no shortage, then it is recommended that you boil water and drink it yourself.

Drink tap water to boil.

Bai's boiling water economy is healthy and economical; If you drink raw water, mineral water is definitely not healthy, and it is generally stagnant water for a long time.

If you boil it and drink it, it is not much different from tap water, but it is too high. If troubled by scale, now there is an economical and practical way to solve the problem of scale in boiling water, in the **shop: Taishan Tiangong, there is a set of ten yuan of patented product scale filter, easy to remove scale, rust and other sediments and suspended solids in boiling water.

Mineral water is good, most of the tap water has bleaching powder, acidic, and the water should be weak and alkaline.

Boiling water is good after high temperature sterilization.

Tap water, mineral water, feels like stagnant water, or living water

It is better to drink tap water after boiling.

Mineral water, mineral water, is more expensive than tap water, of course, there is a reason for it.

Tap water is boiled and drunk. Because tap water contains the right proportion of minerals and trace elements.

And it exists in an ionic state, suitable for human absorption, pure water should not be drunk often, because only water has no minerals and trace elements, and mineral water is water containing certain minerals to be drunk as appropriate, and should not be over-drunk.

However, it should be noted that tap water must be completely boiled before drinking. Reduce chlorine.

Reduces damage to the body.

As long as the tap water is boiled, it can release most of the chlorine gas while sterilizing it.

It will not cause harm to people. Nowadays, many people will install a water purifier for tap water, and the treated tap water will not only have a clearer and cleaner appearance, but also improve the taste. However, the biggest problem with household water purifiers is to clean and replace the internal filter element regularly, otherwise it is easy to become a breeding ground for bacteria.

Summary. Boiling tap water is better, you can drink it with confidence, although the water will contain more or less certain impurities, but the content is very low, after high temperature heating is generally no problem, and it has been disinfected before, as for the scale at the bottom of the kettle, it is some impurities in the water that have condensed into lumps, and the ingredients are calcium and magnesium, you don't have to worry too much, just clean up the scale regularly, it will not affect your health.

Boiling tap water is better.

Boiling tap water is better, it can be drunk with confidence, although the cover water will contain more or less certain impurities, but the content is very low, after high temperature heating is generally no problem, and it has been disinfected before, as for the scale at the bottom of the kettle, the number of scales is pure, some impurities in the water have condensed into lumps, the ingredients are calcium and magnesium, you don't have to worry too much, regularly clean up the water potato, it will not affect your health.

Let's talk about the nuances of the two. The national standards of the two are different, so the ingredients allowed to contain crude jujube are different, but generally speaking, the hardness of tap water is generally higher than that of mineral water (this is not to say that mineral water is better, but the result of focusing on the direction is not old and shouting), so when tap water is boiled, the degree of scale deposition will be more than that of mineral water. The degree of complexity of scale is generally more complex than that of mineral water.

Hello dear! It's a pleasure to serve you. Boiling self-dou guess is good to bring water.

Boiled tap water is the most common and easy to take, but after burning, it is easy to have scale, and in the minds of many people, they think that drinking this kind of water is prone to stones, so they are reluctant to drink tap water. In fact, drinking tap water will not cause stones, and the appearance of these scales will not have much impact on the body of the omen. Tap water contains a certain amount of calcium and magnesium ions.

After high temperatures, these substances form calcium carbonate and magnesium carbonate that are insoluble in water, and after drinking, they will not cause any damage to the body. And because these substances in tap water are all minerals needed by the human body, after drinking, it is actually beneficial to the body, but this amount is limited, if you want to supplement calcium and magnesium, or through other ways, in short, drinking tap water will not aggravate the appearance of stones.

When boiling water, both tap water and mineral water can be used, but the composition of the two types of water is different, so they are used in slightly different occasions. Tap water contains chlorine and other disinfectants, impurities and minerals, so it is no problem to use it for daily drinking, but if it is used to brew high-quality drinks such as tea or coffee, it is likely to affect the taste due to the special taste sharpness and slight temperament differences. In some places, the concentration of heavy metals in tap water is too high, and in a few areas, there are even visible pollutants.

Also, tap water is not suitable for cooking and brewing. Mineral water is relatively refreshing on the palate because it contains fewer chemicals and minerals, especially for drinks that need to highlight the essential taste of water. Because of the less minerals, the boiling time of mineral water is relatively short, and it can also be used for cooking baby milk powder and cooking.

In summary, tap water is usually the most convenient and economical choice for daily boiling water drinking at home, but it is especially necessary to highlight the essential taste of water (such as green tea, flower tea, etc.), or when making high-quality food, seasonings, and boiled baby milk powder, it is more appropriate to choose mineral water.
