Sewage or pure water, sewage and wastewater are different

I have done pure water and sewage, I personally think that pure water does not have too much technical content, sewage is a lot more complicated, if you want to be comfortable, you can engage in pure water, and you want to learn more to go to sewage.

I am doing sewage treatment, I don't know much about the pure water industry, but a large company and a very powerful chief engineer to take you, I still support you to do pure water, there are two years of professional foundation, and pure water is a lot cleaner.

It is recommended to make pure water, from an overall point of view, it is good for the body! The body is the capital of the revolution!

It's still pure water, as far as the test is concerned, it's environmentally friendly, and it's not troublesome.

The difference is obvious! Sewage is good for everything, pure water competition pressure is high, and the sewage market is broad.

Sewage! Beautify the planet! Do good deeds and accumulate virtue! Ascend soon!

The reason for this is that sewage treatment is a big project, and the country is very concerned about it, and if you have your own ideas in this area, put them into practice, and succeed, then the scenery will be endless.

If you want to relax freely、And have a better treatment、Do sewage that! It can also help everyone to purify!!

Pure water: Health is important or future is important.

The main differences between sewage and wastewater are as follows:

1. Sewage usually refers to urban domestic sewage, including wastewater and excrement produced by households, businesses, hospitals, schools, etc., as well as rainwater and groundwater. Sewage contains a large amount of organic matter, inorganic salts and microorganisms, etc., if not directly discharged after treatment, it will have a serious impact on the water environment and the ecological environment.

2. Wastewater refers to the wastewater generated in various production processes, such as industrial wastewater, agricultural wastewater, etc. Wastewater contains a large number of harmful substances such as chemicals and heavy metals, and if discharged into the natural environment, it will cause serious pollution to the environment.

The difference between sewage and hall wastewater:

First, the nature is different:

1. Sewage. Sewage refers to the discharge water from domestic and production that is polluted to a certain extent. Water that has lost its original use function is referred to as sewage.

2. Wastewater. Wastewater refers to the general term for the water discharged from residents' activities and the runoff rainwater.

Second, including different:

1. Sewage. Domestic sewage, industrial wastewater and initial rainwater.

2. Wastewater. Including domestic sewage, industrial wastewater and other non-water such as early rain runoff flowing into drainage pipes.

Third, the characteristics are different:

1. Sewage. The water used in daily life contains more organic matter and is easier to treat.

2. Pretend to be resistant to wastewater.

After a certain technical treatment, it cannot be recycled, or the water that cannot be purified after a level of pollution does not reach a certain standard. <>

What is the difference between purified water and tap water.

2.Pure water refers to the water that has been filtered by a water purifier, while purified water refers to the water that has been filtered through a water purifier;

3.Pure water does not contain inorganic ions, whereas purified water contains inorganic ions.

Purified water: refers to the Ho without impurities, referred to as clean water or pure water, which is pure, clean, and does not contain impurities or bacteria, such as organic pollutants, inorganic salts, any additives and various impurities, and is the raw water that meets the sanitary standards of drinking water.

Purified water: refers to the pharmaceutical water prepared by distillation, ion exchange, reverse osmosis or other suitable methods.

From the above definition, the two most obvious differences can be seen that purified water is drinkable, while purified water is used only for water, and the two are not used for the same purpose. In addition, the preparation methods of these two kinds of water are also different, pure water mainly uses reverse osmosis equipment to remove impurities in the water, without changing the properties of the water, mainly physical treatment, and purified water uses ion exchange method to remove sodium ions and chloride ions in the water, mainly chemical treatment.

Purified water refers to H2O without impurities, referred to as clean water or pure water, which is pure, clean, and does not contain impurities or bacteria, such as organic pollutants, inorganic salts, any additives and various impurities, and is the raw water that meets the sanitary standards of drinking water. It is prepared by electrodialyzer method, ion exchanger method, reverse osmosis method, distillation method and other appropriate processing methods, sealed in a container, and does not contain any additives, colorless and transparent, and can be drunk directly.

Pure water is composed of pure water equipment composed of pretreatment, reverse osmosis and sterilization and disinfection process, and the deep filtration will remove all the substances in the raw water, including colloids, particulate matter, pyrogens, heavy metals, bacteria and viruses, etc., and the water quality is pure and does not contain any polluting substances, which meets the sanitary standards of bottled (barrel) drinking pure water, effectively avoids the invasion of various germs into the human body, can effectively and safely replenish water to the human body, and has the effect of promoting metabolism.

Pure water, also known as high-purity water, is different from pure water in that the water quality is very high, from a chemical point of view, only H2O, almost nothing else, often used in biopharmaceutical, fine chemical, electronic industry, etc., so pure water is more suitable for industrial production applications, not suitable for drinking water.

1. Wastewater, which includes domestic sewage, industrial wastewater and other non-water such as early rain runoff flowing into drainage pipes and canals, generally refers to water that cannot be recycled after certain technical treatment or is not purified after first-class pollution.

2. It is mainly the water after daily use, which contains more organic matter and is easier to treat.

2) Pollution is different:

1. The damage to the environment caused by industrial wastewater is considerable, and the "Minamata Incident" and "Toyama Incident" in the "Eight Major Pollution Incidents" in the 20th century are due to the pollution of industrial wastewater.

2. Industrial wastewater comes from the sewage from manufacturing mining and industrial production activities, including runoff live leachate from industrial or commercial storage and processing, and other wastewater that is not domestic sewage.

Sewage is the water discharged in life and production, and the sewage can be directly discharged into the river after simple treatment.

And wastewater, for example, the water used to flush the toilet in life becomes wastewater, so more and more interior design requires that the bathing place is not directly located with the squatting toilet, so as to increase the measurement of wastewater. Wastewater is difficult to treat, and there are also organic matter, which needs to be decomposed by a variety of anaerobic and aerobic bacteria, and so on.

Industrial wastewater refers to the wastewater discharged from the production process, which includes production wastewater and production sewage. Production wastewater refers to industrial wastewater that is unpolluted or slightly polluted and has a slightly elevated water temperature. Production wastewater refers to polluted industrial wastewater, and also includes industrial wastewater with high water temperature and heat pollution caused by discharge.

Generally speaking, there is no difference, the actual sewage and wastewater are not treated separately, they are treated according to specific types, and it is meaningless to distinguish between the two, in which wastewater is a relative concept, and sewage refers to polluted water.

Term] wastewater.

Pinyin] fèi shuǐ

Explanation] Liquids produced in industrial production that are not useful for the production process. Also called waste liquid. See Three Wastes.

Term] sewage.

Pinyin] wū shuǐ

Explanation] Generally refers to water with an unclean appearance. Such as domestic sewage, industrial wastewater. See "Wastewater" (p. 524).

The difference between domestic wastewater and pure water, 1. The essential difference is that the water purifier with reverse osmosis function adopts food-grade top filter material, and the filtration accuracy of the reverse osmosis membrane of the core filter element is up to microns, which can remove harmful substances such as heavy metal ions, bacteria, scale, pesticide residues, etc., and filter the water produced by the latter to be safe and healthy. Contains a certain amount of mineral salts, trace elements or carbon dioxide gas. 2. The difference in taste of water purifier is not only suitable for areas with serious tap water pollution, but also can filter residual chlorine and other impurities in conventional tap water, and at the same time, water purifiers with post-activated carbon filter elements can improve the taste of water. The pure water is pumped into the water treatment equipment by the deep well pump of the mineral water plant, and then filled and transported, the water temperature has changed, and the calcium has begun to be dissolved.

If it is reheated or refrigerated, the precipitation of calcium increases, and a white precipitate is seen. 3. The difference in safety is that the water filtered by the water purifier is filtered household tap water, which can be directly drunk. Ready-to-use, no secondary pollution, safer.

Pure water has the problem of "secondary pollution". For example, water delivery: whether it is a big brand or a small workshop, without exception, it is hired to pay for dry cars and tricycles to deliver water, and the water delivery process is greatly affected by time, climate, environment, and personnel quality, and the possibility of "secondary pollution" is the greatest.

It is recommended to use the water filtered out by the water purifier for household drinking water, and the Angel A7LITE large-volume water purifier is composed of three parts: ACF composite filter element and reverse osmosis membrane, and aerospace-grade nano whisker post-activated carbon. Angel A7LITE large water purifier can not only provide pure water to drink directly from the faucet, but also provide clean water for rice washing, vegetable washing, dishwashing, fruit washing and other scenes. Angel's long-lasting reverse osmosis membrane can be used for up to 5 years, and has now obtained the world's top ten innovation patents and six international authoritative certifications.

The differences between pure water, purified water, and ultrapure water are as follows:

1. The degree of difficulty of the manufacturing process is different.

The production process of pure water is prepared by reverse osmosis, distillation and other methods.

Purified water is pharmaceutical water prepared by distillation, ion exchange, reverse osmosis or other suitable methods.

Ultrapure water is prepared on the basis of pure water through a series of complex purification technologies such as photooxidation technology, polishing and polishing treatment. This kind of water is difficult to achieve in the general process, theoretically the secondary reverse osmosis can be used to treat the secondary reverse osmosis water through the series of mixed exchange resin columns, but the regeneration of the exchange resin is inconvenient, and the quality is difficult to guarantee.

2. Heavy metals, bacteria, particle numbers and other indicators are also very different.

The impurity content of pure water is ppm level, while ultrapure water is ppb level, in addition to water molecules, there are almost no impurities, and there are no bacteria, viruses, chlorinated dioxins and other organic substances, of course, there are no minerals and trace elements required by the human body, that is, water that almost removes all atoms except oxygen and hydrogen.

3. The use is different.

Pure water is mainly used in biology, chemical engineering, metallurgy, aerospace, electric power and other fields.

Purified water is generally used for medicinal purposes.

Ultrapure water is generally used in electronics, electric power, electroplating, lighting appliances, laboratories, food, papermaking, daily chemicals, building materials, painting, batteries, testing, biology, pharmaceutical, petroleum, chemical, steel, glass and other fields.

4. The conductivity is different.

The conductivity of pure water is between 2-10us cm, the conductivity of purified water, and the conductivity of ultrapure water is .
