In unpolluted rural areas, well water can be drunk when pumped up, and it has not expired for hundreds of millions of years. But you wake it up and put it in a bottle, and you can't drink it after a while. It's expired. A small pond, if it is natural running water, is clear and clean, and can be used for swimming and playing. If it is artificially shielded, you won't dare to go down immediately. This is the circular purification function of nature.
Running water does not rot, the water in the bottle is called stagnant water, and the sunlight extracts pure water from the sea to form clouds. The wind brings it to the top of the mountain to form raindrops, supplements winter minerals through underground rivers, and filters through underground sand layers, which is human drinkable water, and so on. First of all, we should know that the earth is a magical existence with a powerful self-repair system and a perfect recycling system. The earth just balances the relationship between every substance and every life. The water evaporated, and then there was rain. The rain fell to the ground and was filtered by nature to form water, which kept circulating. Water has also given freshness and vitality to all kinds of life on earth in a series of self-purification and regeneration activities.
All the water in this river comes from rain. Where does the rain come from? Evaporation! In other words, distilled water is constantly added to rivers and lakes, and dirty water flows out into the ocean, which is sterilized by high salt, biodecomposed and evaporated to produce rainwater! There are fish, snails and bacteria in the river, all of which are constantly decomposing the organic matter in the river! If you want to extend the shelf life of a bottle of mineral water, please don't touch the bottle mouth when drinking water, because if your lips touch the bottle mouth when drinking water, the bacteria in saliva will make the remaining mineral water start to deteriorate and rot in a few hours, and form good habits. Mineral water tastes good and won't go bad.
This is why there are quality supervision departments and quality inspection departments. Packaging water has a shelf life. You won't know if it's expired until after the shelf life. Of course not, because you can't see the word shelf life. Just like when you see a person, you can only see that he is a man, a woman, an old man, a middle-aged man and a child, but you don't know his last name. When you see his ID card, you will know his name and age. The flowing water has high oxygen content, so there will be nitrifying bacteria. , can decompose some organic matter and prevent water quality corruption. The same is true of fish tanks. Circulating water, exploding oxygen, cultivating nitrifying bacteria and ensuring water quality are the essence of running water.
First, it seems that China has always had a theory of keeping in good health, and Chinese medicine is based on keeping in good health. Second, the understanding of water has deepened with the development of science and technology. It is not clear whether water can be drunk, and running water may not be drunk directly. For example, there are many bitter wells in northern Shaanxi, and you can't drink them at all. Third, the river water in northern Shaanxi is seriously short of iodine, which leads to big neck disease becoming an endemic disease in these areas. However, some mountainous areas in Hunan and Hubei are located in calcareous rocks, and the running water contains a lot of calcium sodium, which is not suitable for direct drinking. 4. The surface layer of the soil I used to work in the field was gypsum. The water used is very clear, but the fluorine content is very high. My teeth are black and loose after drinking for a long time. And so on, these show that running water does not rot is only the appearance.
Water flows from high pressure to low pressure and from low pressure to high pressure in nature. Reciprocating circulation is not bad at all, but the water in the container will naturally produce microorganisms if it does not flow, and too many microorganisms will deteriorate. Nowadays, many rivers are stagnant water, and only by letting them flow can there be green mountains and green waters. The first step is to blow up some unimportant gates and let some of them often discharge downstream, so that the water will move and the ecosystem will recover slowly, and it is necessary to ensure that every river is free from industrial pollution. It's actually the expired bottle. Although it takes a long time for plastics to decompose, after a certain period of time, plastics will produce chemicals harmful to human body. So the expired water is not water but plastic bottles. Of course, this only lies in the plastic bottles bought in the supermarket, if other quality bottles can have different factors.
When the water body is large enough, it will have self-purification function, which is an ecological balance. There are bacteria in water, plankton and aquatic plants that kill bacteria, and so on. Bacteria are also a species and have natural enemies. Neither side can dominate? The small body of water in the water bottle is only suitable for bacterial reproduction. The water on the earth is constantly circulating. Water keeps evaporating, then it rains, and then it is evaporated. This is a distillation process, so there will be a steady stream of clear water. The water in the bottle is stagnant water, and microorganisms will slowly occupy the whole bottle of water.
To put it bluntly, everything has been artificially changed and transformed, and the attributes of things have lost their original essential attributes. For example, bottled water, artificially filtered and added with trace elements, is not natural water. In other words, it has become a commodity, and everything has a production and exclusive shelf life. Everything is a natural phenomenon, and no one thinks that the shelf life is limited!
First of all, water is a combination of two molecules, oh. Macroscopically, oxygen molecules and H molecules are not bad. Of course, the combined water will not be bad, and there is no shelf life. Why does accumulated water deteriorate after a long time? In fact, it is not the deterioration of water, but the deterioration of substances in water for a long time. In order to keep the water from stinking, it must be continuously filtered and circulated, just like rivers and streams. You can also let the creatures living in the water purify the water. Of course, this requirement is relatively high, for example, it should be large enough, and there are many creatures in the water, just like a big reservoir.
Why has water not expired on earth for billions of years, and there is a shelf life when it is put in a bottle? First of all, the water on the earth for billions of years has not expired, which means that the water on the earth for billions of years has not deteriorated, which means that it has not deteriorated. The reason why this water doesn't go bad is because the water on the earth keeps flowing, running water doesn't rot, and hinges don't bug. In other words, they resist the invasion of microorganisms in constant movement, so the flowing water will not deteriorate or deteriorate. In addition, why does the water on the earth always flow for billions of years?
Because, due to the response of the moon, the sea water rises and falls every day, and the sea water in the north and south poles and the equator is irradiated by the sun, forming a cold current and a warm current of the ocean, which also makes the sea water flow forever. There is also the gravity of the earth, which can make the river water flow from high places to low-lying seas. All these reasons can keep the water on the earth flowing, so it will never expire.
Besides, bottled water is generally the drinking water for people or livestock. Bottled water is bottled after disinfection, processing and filtration. For people, people can use it directly after opening the bottle without boiling it. Because of this, bottled water has a shelf life. Otherwise, bottled water is static and will rot and deteriorate over time.
So artificially set a shelf life for bottled water. Speaking of which, by the way, this microorganism came from the earth after birth, just like other creatures. Before the microscope appeared, people didn't know what a microorganism was, only that it was poisonous and which was not. After the invention of the microscope, people didn't know what microorganisms were. Microorganisms include viruses and germs, as well as beneficial bacteria. If you look at the world with microscope glasses, you will find that the whole world is full of microorganisms, which can decompose all objects without antibodies. Therefore, germs and viruses are the pathogenic sources of human external factors.
Quite simply, water in nature has different purification processes in different environments. A great deal of water exists in the ocean on the earth. After the sun shines, it will be evaporated and purified, and the generated water vapor will be brought to the mainland to cool and condense to form rainfall. Some will form surface rivers, and some will infiltrate into the land to form groundwater. This process is a purification process. This process will always circulate and purify.
