It goes through the sewer to the sewage plant, where it is treated and discharged into the seawater. The water of the seawater is evaporated by the sun and turns into clouds. The clouds drift to land and then it rains.
Domestic water refers to the water needed for human daily life. Including urban domestic water and rural domestic water. Urban domestic water is composed of residential water and public water (including water used in the service industry, catering industry, freight forward, post and telecommunications industry, and construction industry), and rural domestic water includes livestock water in addition to residents' domestic water.
Drink in moderation and rich in calcium ions.
Water with magnesium ions is good for health, magnesium ions help to activate the body, and magnesium ions also have the function of stabilizing neuromuscular conduction. Therefore, when the concentration of magnesium ions in the body is too low due to insufficient magnesium intake, it is easy to cause arrhythmia and abnormal constriction of blood vessels. Normal people need to consume at least 350 mg of magnesium ions from food or water every day to maintain good health.
Since magnesium ions ingested from food are easily combined with fiber in food and are not easily absorbed by the body, the most effective way to increase the absorption of magnesium ions in the body is to consume them from drinking water. Calcium and magnesium ions are essential nutrients for the human body every day.
If the water has a certain hardness, a certain amount of calcium and magnesium ions can be replenished by drinking water.
If you are taking soft water for a long time.
need to be supplemented by other means. But it's not good to have too much or too little hardness of water, because the hardness of water is closely related to some diseases. In areas with higher water hardness, the population has cardiovascular disease.
The incidence is low, but kidney stones.
The incidence increases with the hardness of the water.

It then passes through the sewer to the sewage plant, where it is treated and discharged into the seawater. The water of the seawater is evaporated by the sun and turns into clouds. The clouds drift to land and then it rains. After the rain, it comes to the rivers and lakes, and finally to the reservoir, where it is sent to the bathtub through the water pipe. So it's circular. Hope.

To the river, to the sea, then to evaporate, then to rain.

Generally, tap water in large cities is recycled, such as bathing water and domestic wastewater.
and so on, all of which are gathered together and reused after sterilization and disinfection, mainly to save resources!
But don't worry, the water is definitely healthy, and the treated water can be used for bathing and washing, so don't worry!

The circulation of water in nature is closely related to our lives, such as: we can irrigate crops, water flowers, water trees, row, swim, wash clothes and cook, and generate electricity. Harm; Floods, washing away houses and crops, tsunamis, mudslides, etc.
The main role of the water cycle is manifested in three aspects:
1. Water is the medium of all nutrients, and the circulation of nutrients and the circulation of water are inseparably linked.
2. Water is a good solvent for substances, and plays a role in energy transfer and utilization in the ecosystem.
3. Water is one of the causes of geological change, the loss of mineral elements in one place, and the deposition of mineral elements in another place is often completed through the water cycle.
-
The circulation of water in nature has both beneficial aspects to people's production and life, such as bringing us fresh air, helping plants sprout and so on. There are also downsides, such as: frost, floods, and so on.

It has a lot to do with it, there is no water cycle, and in some places there is drought and lack of water. The circulation of water in nature, such as rainfall, has too much to do with it.

large circulation) and connect various water bodies so that various water bodies can exist for a long time. The exchange of water between the sea and the land is the main thread of this cycle and is of the greatest significance. Under the action of solar energy, the water on the surface of the ocean evaporates into the atmosphere to form water vapor, which follows.
Atmospheric circulation. movement, part of which enters the sky over the land, forming precipitation such as rain and snow under certain conditions;

and surface runoff eventually return to the ocean, creating a dynamic cycle of freshwater. This part of the water is easy to be used by human society and has economic value, which is exactly what we call water resources. The water cycle is the "link" that connects the earth's circles and various water bodies, and it is the "regulator" that regulates the earth's various bodies.
Circles. between energy and cold plays an important role in warm and cold climate change. The water cycle is the "sculptor" that shapes the colorful image of the surface through erosion, transport and accumulation.
The water cycle is the "conveyor belt", which is a powerful driving force for the migration of surface materials, and the main carrier. What's more, through the water cycle, the ocean is constantly pumping fresh water to land, replenishing and renewing new land.
freshwater resources, thus making water a renewable resource.

When precipitation reaches land, water flows into the ocean, mixes into the ground, and a part of the water evaporates into vapor, which enters the atmosphere, where it cools and turns into water.

Who knows, come and tell me! Emergency.
Analysis: There are many links in the water cycle. Any one link stops and it will have a serious impact.
Let's just say that if the water can't flow, the substances in the water will accumulate more and more, and it will be a stinky pool. If the water can't evaporate, then let it all flow into the sea, and the sea will become more and more until the glaciers melt and flood many places. This is still a coastal area, if it is inland, because the water has flowed, and there is no rain supply, it has long been dry and messy, there is no rain, and there are no rivers, but the lake can still be used, with a little less and a little bit of a model, it will not increase, because the water cannot evaporate.
For example, the amount of water we use now will soon be gone in 3-4 years, and even the groundwater will be gone.
If the cycle stops, there is no life. Generally this is still not possible. Because it is human beings who are destroying a certain link, in fact, there will be some corresponding effects, such as due to the increase in temperature, the melting ice reputation has caused more Sichuan, and it has not been replenished in time, resulting in a rise in sea level.
As a result, all kinds of typhoons and huge waves kept coming. If you look at the number of typhoons in recent years, you will know a lot.
The water cycle as we understand it is a simple model, but it is actually a very complex integrated system. It should be considered from a philosophical point of view of the relationship between the part and the whole.
1.A good property of solutions is that the melting point (freezing point) will be reduced, for example, we must have experimented in junior high school where the freezing point of alcohol was reduced after mixing with water. >>>More
We also have water, clouds, rainbows, snow, ice, and children who are water mothers in our lives. >>>More
At the age of 22, do I still need to use cream after using water, serum, and lotion? This is a very common question. Before I get into that, I'd like to emphasize that different people's skin types and needs may vary, so I'm just offering some suggestions for reference. >>>More
