什么是纯净水？

What is pure water?

纯净水指的是不含杂质的H2O，简称净水或纯水，是纯洁、干净，不含有杂质或细菌的水，如有机污染物、无机盐、任何添加剂和各类杂质，是以符合生活饮用水卫生标准的水为原水。通过电渗析器法、离子交换器法、反渗透法、蒸馏法及其他适当的加工方法制得而成，密封于容器内，且不含任何添加物，无色透明，可直接饮用。市场上出售的太空水，蒸馏水均为纯净水。

Pure water means H2O, which is not impurities. It is called pure water or pure water. It is pure, clean, and contains no impurities or bacteria, such as organic pollutants, inorganic salts, any additives and all kinds of impurities. It is water that is in line with the hygienic standard of drinking water as raw water. It is made by electrodialysis, ion exchanger, reverse osmosis, distillation and other suitable processing methods. It is sealed in containers and contains no additives. It is colorless and transparent, and can be directly consumed. The market for sale of space water, distilled water is pure water.

所谓的纯净水就是将天然水经过多道工序处理、提纯和净化的水。经过多道工序后的纯净水除去了对人体有害的物质，同时除去了细菌，因此可以直接饮用。

The so-called pure water is the water that treats, purify and purify natural water through many processes. The pure water after a multipass process removes the harmful substances to the human body and removes the bacteria, so it can be drunk directly.

水是维持生命的必需，一些健康专家建议至少八杯，但并无确切的规定，水的需求量因人而异，这取决于主体的条件下，适量的体育锻炼，和对环境的温度和湿度。人每天的水的来源包括饮用水、饮料、水和食物中的水。饮用水对矿质营养的摄入也不清楚。一般而言无机矿物进入地表水和地下水通过雨水径流或通过地壳，使水中包括钙，锌，锰，磷，氟和钠的化合物。从水产生的营养物质提供了一些节肢动物和沙漠动物的日常用水需求的一个重要部分，但只提供一小部分的人的必要的摄入量，因此并无科学依据不能长期饮用纯净水。但过度饮水也会导致水中毒（导致低钠血症）

Water is a necessity to maintain life. Some health experts recommend at least eight cups, but there is no definite rule. The demand of water varies from person to person, depending on the condition of the main body, the right amount of physical exercise, and the temperature and humidity of the environment. People's daily sources of water include water in drinking water, drinks, water and food. The intake of drinking water for mineral nutrition is not clear. Generally speaking, inorganic minerals enter surface water and groundwater through rainwater runoff or through the crust, so that water can contain calcium, zinc, manganese, phosphorus, fluoride and sodium compounds. Nutrients from water provide an important part of daily water demand for arthropods and desert animals, but only provide a small part of the necessary intake of human beings. Therefore, there is no scientific basis for long-term drinking of pure water. But excessive drinking can also lead to water poisoning (causing hyponatremia).

如何制取纯净水？

How to make pure water?

纯净水可通过电渗析器法、离子交换器法、反渗透法、蒸馏法及其他适当的加工方法制得而成，密封于容器内，且不含任何添加物，无色透明，可直接饮用。

Purified water can be made by electrodialysis, ion exchanger, reverse osmosis, distillation and other appropriate processing methods, sealed in containers, and without any additives, colorless, transparent, and can be directly consumed.

饮用纯净水的工艺为：

The technology for drinking pure water is as follows:

原水--砂滤--碳滤--精滤--一级反渗透--二级反渗透--臭氧杀菌

Raw water -- sand filtration -- carbon filter -- fine filtration -- primary reverse osmosis -- two stage reverse osmosis -- ozone sterilization

纯净水的工艺严苛，特别是反渗透技术是当今最先进、最节能有效的膜分离技术。最初用于海水淡化，其孔径非常微小，仅为10-10，它能分离溶液中离子范围和分子量几百的有机物，去除水中的溶解的盐类、胶体、微生物、有机物等，从而获得纯净的、安全的水。

The technology of pure water is strict, especially the reverse osmosis technology is the most advanced, most efficient and effective membrane separation technology. Initially used for seawater desalination, its pore size is very small, only 10-10. It can separate the ionic range and molecular weight of hundreds of organic compounds in the solution, remove the dissolved salts, colloids, microorganisms and organic matters in the water, so as to get pure and safe water.

反渗透技术是将原水经过精细过滤器、颗粒活性碳过滤器、活性碳过滤器等,再通过泵加压,利用孔径为1/10000μm(相当于大肠杆菌大小的1/6000,病毒的1/300)的反渗透膜(RO膜),使较高浓度的水变为低浓度水,同时将工业污染物、重金属、细菌、病毒等大量混入水中的杂质全部隔离，从而达到饮用规定的理化指标及卫生标准。反渗透设备应用膜分离技术，能有效地去除水中的带电离子、无机物、胶体微粒、细菌及有机物质等。

Reverse osmosis technology is the raw water through the filter, fine granular activated carbon filter, activated carbon filter, and then through the use of pump pressure, aperture of 1/10000 m (equivalent to the size of the Escherichia coli 1/6000 virus, 1/300) reverse osmosis membrane (RO membrane), the high concentration of water into low concentration water. At the same time, industrial pollutants, heavy metal impurities, bacteria, virus and other large mixed with water so as to separate all drinking provisions of the physical and chemical index and hygiene standards. The application of membrane separation technology in reverse osmosis equipment can effectively remove charged ions, inorganic substances, colloid particles, bacteria and organic matter in water.

一般情况下纯净水在生产过程中，源水只有50%-75%被利用，也就是说，1公斤自来水或地下水大约只能生产出0.4公斤左右的纯净水，而剩下的0.6公斤左右的水不能当作饮用水，只能另作它用。

In general, pure water is only used for 50%-75% in the production process, that is to say, 1 kilograms of tap water or underground water can only produce about 0.4 kilograms of pure water, while the remaining 0.6 kg of water can not be used as drinking water, it can only be used for other purposes.

在中国，纯水器的出水水质卫生要求应符合中华人民共和国卫生部1998年颁布《反渗透饮水处理装置卫生安全与功能评价规定》中的要求。

In China, the hygienic requirements for the effluent quality of the water purifier should meet the requirements of the Ministry of health in 1998 promulgated the "evaluation regulations for the safety and function of the reverse osmosis drinking water treatment device" issued by the Ministry of health in 1998.

纯净水灌装方式？

Pure water filling method?

目前，市面上纯净水的灌装方式多种多样。但以大桶装和小瓶装为主要市场，近几年，随着人们的生活水平的提高，4L--7.5L的小桶也开始逐渐占领高端市场，持续影响改变着现代人的生活水平。

At present, there are many ways of filling pure water on the market. But the big and small bottles of bottled as the main market, in recent years, with the people's living standard improved, 4L--7.5L keg also gradually began to occupy the high-end market, the continuing impact of changing people's life level.
