Where did the water come from? Where does the water we use come from?

The Earth's water is more than the primordial atmosphere. In the early days of Earth's history, the Earth's temperature was high. Water vapor and atmosphere mix together.

Later, as the earth cooled slowly, the gaseous water condensed into liquid water. The amount of water vapor in the primordial atmosphere was enormous, and after tens of thousands of years of uninterrupted rainfall, the primordial oceans were also produced.

The ancients said that the water of the Yellow River came from the sky.

The water we use is tap water.

The ** of tap water is surface water and groundwater, which needs to be treated by the waterworks and can only be supplied to people after reaching a certain standard.

This includes water from lakes, rivers, springs, and so on.

Before the water is delivered, the water is precipitated, filtered and disinfected, and then the purified clean water is sent to the water tower and storage tank, or through a large outlet pipe. The plant's large outlet pipes are connected to the underground water pipeline, which in turn connects to the taps of thousands of households.

So, whenever you turn on the faucet, the water will flow out.

It should be reminded that although tap water has been processed and treated many times, it still contains a small amount of germ substances, so you must not drink tap water that has not been boiled.

Where does the water that people use in their lives come from? Because many people know that the water we use comes from tap water, which is provided by the water supply company, and it is enough to pay the water bill at the time of each month; Do you know what's in the water you use every day? Do you really know what this water has gone through before you use it?

Today, let's sort out for you how the water we use every day comes from. In rural areas, it is not necessary to talk about it, except for the tap water that has been used (tap water will be discussed next) is to directly dig a well, using groundwater; The quality of groundwater is relatively clean, so it can be used normally after being filtered in rural areas. And what if in the city?

There are many more processes before the use of domestic water, and the general urban water is directly taken from rivers and lakes, and then after treatment, it is transported to the user for use; Do you want to know what happened between taking water and using it? Next, let's talk about several common processes experienced between the time the water is taken and the user uses it;

The water that meets certain quality standards and quantity requirements is called the water source, the water in the water source will not flow to the treatment plant by itself, it needs a water intake structure, and the main role is to take water from the water source, usually including the water intake pump room and the structure before the water intake pump room; Now the water needed for the first step has been taken out, and the water taken out is generally called raw water, of course, this raw water cannot be used directly; What to do? This is the second step of the water treatment structure, the water treatment structure is to use physical, chemical and biological methods to economically and effectively treat the raw water that has been obtained, so as to improve the water quality, so that the treated water meets the water quality requirements of the user; Now the raw water taken out has been effectively treated, and it has already met the requirements of domestic water. But now that the water is still in the water treatment structure, that is, the water treatment plant, how can the water be delivered to the user, that is, to us?

This means that after the water is taken and treated, the water that has been treated can be delivered to us by using the water pumping station;

Generally speaking, this is the case with domestic water, of course, not only that, but in the following time, we will slowly talk to you about how the water we see every day comes from and how the used water is treated.

The ** of water is space and the interior of the earth. There are three ways for water to come to Earth from space, one is a meteorite that falls on Earth, the second is a water molecule formed by protons from the sun, and the third is a comet made of ice from space.

Our domestic water is pumped from rivers and lakes to waterworks, and then transported to the taps and water points of thousands of households through water supply pipelines after dosing, coagulation, sedimentation, filtration, and disinfection.

There are many types of drinking water**, one of which is that it is pumped from the ground through wells. This groundwater is relatively pure, so it does not have too many contaminants and is suitable for drinking. Drinking water can also be obtained directly from surface sources such as rivers, lakes, streams, etc.

Usually surface water has to go through more purification treatment than groundwater before it can be drunk, so drinking water obtained from surface water is more expensive. Despite this, 66 people worldwide still use surface water systems.

Drinking water includes groundwater, river water, snow-capped mountain meltwater, mountain spring water, .......

No matter the best water, it needs to be treated and tested by the water company before it can be drunk.

The state has strict standards for drinking water!

OneIn the early days of the Earth's formation, hydrogen and oxygen in the atmosphere reacted to form water, and the water vapor gradually condensed to form the oceans.

II. II. IIIn the early days of the earth's formation, the decay of radioactive elements such as uranium and thorium in the interior emitted heat, and the interior of the earth was melted, and the water in the rocks was separated.

IIIVolcanic eruptions release large amounts of water. After a volcanic eruption, magma flows to the surface, and as the pressure decreases, water is released. 4. The dehydration of minerals in the earth's interior decomposes part of the water, or releases carbon monoxide, carbon dioxide and other gases, which react with hydrogen at high temperatures to form water.

Water hardness is an important criterion for evaluating water quality, which has a very important impact on drinking water and industrial water. Too high water hardness may form scale, which can affect product quality. Therefore, in order to determine the water quality and carry out the related treatment of water, it is necessary to measure the calcium and magnesium ions in the water, that is, the total hardness of the water.

The monitoring and analysis of total water hardness is one of the important tasks of water quality testing, which not only affects the quality of water, but also affects the safety of people's production and life. Today, with the rapid development of science and technology, the application of more detection technologies has improved the accuracy of total water quality detection, and ensured the safety of water quality and the quality of use.
