The huge increase in scale means that the hardness of water is extremely high. Generally, the drinking standard of drinking water hardness is below 50PPM (inaccurate), and the hardness of tap water is also around 50-60PPM, but the groundwater is much higher. In 2000, I sent a water sample from a 200-meter deep well in Suzhou, and the hardness was above 2000PPM.
If you drink it, the water quality must meet the drinking water standard, otherwise the drinking water standard stipulated by the health department is useless.
If you really can't drink qualified drinking water, let the water with high hardness boil and burn for a long time, so that bivalent calcium and magnesium ions in the water react with CO2 in the air to generate precipitation, thus reducing the hardness and the scale will sink to the bottom, so don't pour it into the cup when pouring.
What harm does drinking alkaline water for a long time have to the body? At present, the micro-electrolysis water generator on the market can instantly activate ordinary water into weakly alkaline functional water, but it can't solve the problem that alkaline functional substances in cups are constantly dissolved after long-term soaking. Scientific research experiments show that it becomes weak alkaline water in a few minutes, strong alkaline water in 1 hour, and toxic alkaline water in 5 hours, which has great potential safety hazards! A friend of a retired veteran cadre in Northeast China gave a brand-name micro-electrolysis water machine. One morning, he made a glass of water, and when he came back in the afternoon, he drank half a cup. He felt thirsty and uncomfortable at once. He went to the hospital for a check-up. It was alkalosis. After testing, the PH value of that glass of water was as high as 10.36, and it became toxic and alkaline water. Doctor's suggestion: weak alkaline water is good for health, but drinking strong alkaline water for a long time is very harmful to human body! At present, only the water produced by the gold-for-function cup is permanently weakly alkaline! Good money won't change! Safe money is the same! The health of the whole family is priceless!

What harm does drinking acidic water for a long time have to the body? Seven standards of healthy water first, clean and pollution-free water. Second, it contains essential mineral elements for human body. The ions of this important element affect or determine the pH value, hardness and water mass of water. Third, weakly alkaline water. The PH value is preferably 7.00-8.00 to maintain the acid-base balance of the body. Fourth, small molecular groups of water. The half-width of the water mass should be less than100hz as measured by nuclear magnetic resonance * * * vibration method; If the amplitude of * * * is very wide, it means that the water molecules in this water string together to form a chain coil structure with a large diameter, which is not easily absorbed by the human body through the cell membrane. The history of water can also be tested by quantum micro-magnetic fluctuation method, and the water with positive value of +20 is the best; When the negative value reaches -20, the condensed structure of water molecules has no mediating effect on the biochemical reaction of human body, and this kind of water is stagnant water. Fifth, maintain a certain hardness of hard water. Various ions in water constitute the hardness of water. Hard water contains high calcium. Hard water can prevent harmful components (such as lead, cadmium, chlorine and fluorine) from playing a harmful role. Studies have shown that longevity is related to drinking hard water frequently. The distinction between hard water and soft water is generally based on the total hardness of 75mg/ 1 (calculated by calcium carbonate), at 30? Between 200. Sixth, the dissolved oxygen and carbon dioxide in the water are moderate (the dissolved oxygen in the water is not less than 7 mg per liter). Seventh, living water, that is, water whose nutrition and physiological functions have not deteriorated, has vitality. The functions of water include solubility, permeability, diffusion, metabolism, emulsification and cleaning. In short, drinking water has "three suitability and three inadvisability": it is advisable to drink weakly alkaline water, not acidic water; It is advisable to drink small molecular water, not large molecular water; Drink hard water instead of soft water. How to distinguish acidic water from alkaline water? What are the characteristics of acidic water? ) * * * Whether the water contains minerals and trace elements is the key to determine its pH value. The pH value of water is determined by the ions contained in the water. The PH value, that is, the acid-base strength, indicates the activity of ions. * * * * The PH value of natural water is generally between 7.0 and 8.0, which is weakly alkaline; The PH value of pure water is generally between 5.0 and 7.0, which is acidic. * * * * There are tens of thousands of enterprises producing pure water (or ultrapure water) in Chinese mainland, many of which are made by reverse osmosis technology. Purified water not only removes impurities from water in the production process, but also filters out mineral elements necessary for human body in water. * * * * Pure water is an active absorbent. When it comes into contact with air, it will absorb carbon dioxide in the air, dissolve quickly and become acidic. The more pure water you drink, the more acidic substances you will have. * * * * Pure water is a kind of artificial water, which has never been seen in nature and is a "foreign body" for human cells. It is macromolecular water, soft water, acidic water, water with degraded and alienated functions and unhealthy water. Why not drink pure water (acidic water) often? * * * * expert in water physiology (Professor Jin is from beijing university of chemical technology Water Resources Research Center, etc. ) It is clearly pointed out that after the mineral elements are lost in pure water, the structure and function of water have also changed accordingly. Water molecules are excessively connected in series to form a linear structure, which is not only difficult to be absorbed by the human body through the cell membrane, but on the contrary, the life element ions in the cells will reversely penetrate to the outside of the cell membrane and enter the "linear cluster" of pure water, so that the beneficial life-related elements in the human body are excreted. * * * * Pure water has a greater negative effect on growing children. Water nutrition experts stressed: 30% of children's calcium demand comes from water, not completely from food, and 30% of drinking pure water is gone, which is the first impact; Secondly, the absorption of calcium in food is much slower than that in water, and the absorption rate of calcium in water can reach more than 90%, while the absorption rate of calcium in food is very low, only 30%, which is due to the influence of other nutrients, including crude fiber and phytic acid. * * * * Consumers Association issued a consumption reminder in March 2003: Experts pointed out that most people are suitable for drinking weakly alkaline water, especially the elderly, children and infants, and pure water is not suitable for drinking in large quantities and for a long time. This is a conclusion with the nature of "official remarks". * * * * In July 2000, Xinhua News Agency reported "expert warning": "Pure water" should not be used as ordinary drinking water for a long time, especially for infants and children. * * * * CCTV Weekly Quality Report: Experts interpret "Pure water is not suitable for children". * * * * As early as 1957, Japanese scientists proved that the death rate of stroke is closely related to the acidity in drinking water. * * * * American scientist Burton analyzed the drinking water in 0/00 big cities in the United States and found that the alkalinity of water is the key factor to reduce cancer mortality; Another scientist, Schroeder, also observed that drinking acidic water is more likely to cause cardiovascular diseases. * * * * expert in water physiology (Professor Jin is from beijing university of chemical technology Water Resources Research Center, etc. It is pointed out that some sensitive people feel that the more pure water they drink, the less they will quench their thirst. The more they want to drink, the more they feel weak for a long time. That's because drinking pure water often can't supplement trace elements such as calcium and zinc, but it will take away the existing minerals in the body by pure water, which will reduce people's immune function and even cause diseases such as hypertension, heart disease and cancer. What benefits does alkaline water have to the body? * * * * Regulating the acid-base balance of human body: Basic functional water is not medicine, but it can play a role that medicine can't. Medical proof shows that the human body is in a state of internal alkali and external acid. Alkaline functional water can adjust the acid-base balance of human body, make the inside of human body reach the best state, and eliminate the foundation of disease through the normal operation of human body. This is a fundamental method, so some people say that "water is the king of all medicines" * * * enables human cells: alkaline functional water is small in water mass, strong in solubility and permeability, easy to enter cells, and can promote human metabolism and waste. Small molecular functional water contains a lot of freshly dissolved ionic oxygen and a lot of trace elements suitable for human needs, which can be purified by entering cells and blood. Small molecular water can also decompose fat in human body, which can reduce the accumulation of fat. Basic functional water can emulsify the cholesterol on the blood vessel wall and excrete it.

Basic knowledge of drinking water safety
First, choose common sense of drinking water
(1) Give priority to drinking bottled water or boiled water. If you don't have the conditions to boil water, you can drink water sterilized by disinfectant. Don't drink polluted water, and don't wash it with turbid and colored water.
(2) Well water and spring water are preferred for water intake, and river bank seepage water can also be selected.
(3) Water containers should be disinfected frequently and washed with clear water.
(4) Water with the smell of disinfectant is safe drinking water.
(5) The order of selecting water sources is well water, spring water, mountain stream water, river water, reservoir water, lake water and pond water. However, according to the actual situation and water quality analysis results, water source protection areas should be delineated, and water sources should be identified to strengthen water source protection.
(6) protect drinking water sources.
Second, measures to protect drinking water sources
(1) Within 50m around the water source well or 30m along the surface water source, it is forbidden to build toilets and livestock pens, discharge feces, sewage or dump garbage, and spray pesticides at the water source.
(2) unified disinfection management of feces, timely removal of dead animals and livestock, and immediate landfill treatment. The landfill should be more than 0/50m away from the water source/kloc-and away from the residents' daily living area, and the landfill depth should be more than 40cm. Lime (1/4 ~ 1/2) should be added during landfill, and the landfill site should be marked after landfill.
(3) Set a simple diversion ditch in the water source area to prevent rainwater or sewage from carrying pollutants directly into the water source area or its upstream area; For water wells, pollution interception measures should be set around, well platforms should be built, drainage ditches should be dug, and water wells should be covered to prevent pollutants from entering. Disinfect well water regularly every day and use public buckets to get water.
Third, a simple method to judge the quality of drinking water
Look: clean water should be colorless, free of foreign objects and floating dead animals.
Smell: Clear water has no peculiar smell;
Taste: Clean water has no taste. If it is found to be sour, astringent, bitter, hemp, spicy and sweet, you can't drink it.
Inspection: If conditions permit, you can use a water quality (quick) tester to quickly inspect the water quality, and you can drink it only after it is qualified.
Four, drinking water disinfection method
(1) Domestic and personal water: boiling disinfection is reliable, and the method is simple and easy. Halogen preparations such as bleaching powder can also be used for disinfection of drinking water.
① Disinfection method of bleaching powder tablets: mix 100 kg of clean water and 1 tablet of bleaching powder evenly, and let it stand for 30 minutes before drinking;
(2) Disinfection method of sodium dichloroisocyanurate tablets: mix 100 kg of clean water and 5 sodium dichloroisocyanurate tablets (effervescent disinfection tablets) and let them stand for 30 minutes before drinking;
(3) Disinfection method of chloramine: firstly, chloramine is prepared into 10% solution, and 5 ~ 6 ml of water is added to each 100kg, which is evenly mixed and stirred, and then allowed to stand for 30 minutes before drinking;
(4) Sodium hypochlorite disinfection method: add 5-6ml 10% sodium hypochlorite to 100kg of clean water, mix and stir evenly, and stand for 30 minutes before drinking;
⑤ Add 2 water purification tablets or 5 drops of 2% iodine to each liter of personal drinking water, shake well for 2 minutes, and let it stand for 10 minute before drinking.
(2) Well water: the well water quantity is calculated according to the depth and diameter of the well water, and the amount of disinfectant is calculated in proportion.
(3) Centralized water supply unit: to remove pollutants and sludge left over from disasters and clean water-making facilities and equipment, it is necessary to ensure that after adding disinfectant, it stays in the clean water pool for more than 30 minutes, and the free residual chlorine content in the factory water is detected within the range of 0.5 ~ 65438 0.0 mg/L, or to ensure that the free residual chlorine content in the end water of the pipe network reaches 0.65438 0 mg/L. ..
(4) Emergency drinking water treatment steps: coarse filtration → standing/settling → filtration → disinfection.
Drinking alkaline water for a long time, what harm does it have to the body? There may be more calcium and magnesium ions in water with too strong alkalinity, which is beneficial to bone growth, but it may be easy to produce stones.
Is it harmful to health to drink solar water for a long time? The state has no special regulations and standards for this. In the past, they have detected water in solar energy in a small scale, and the results show that nitrite obviously exceeds the standard. Nitrite can poison people. This is because tap water contains some organic matter, which will produce nitrite when stored for a long time, while solar energy is easy to accumulate old water in ordinary families. In addition, some harmful substances released by paint and plastic water pipes in water tanks may be dissolved in water if they are soaked in hot water for a long time, so it is not recommended to drink solar energy. You'd better pay attention.
What effect does drinking water with high alkalinity have on human health? Alkaline substances, you need to see if they are corrosive. If they are corrosive, you must not drink them. If not, you can only drink the one with a PH of 7-7.5, otherwise it will do harm to people's health.
What harm will drinking drinks for a long time do to your health? Relatively speaking, carbonated drinks with pure fruit juice are rich in nutrition, and some drinks have a small amount of pulp precipitation, so vitamins can be supplemented appropriately, but they are more suitable for young people and children, but you can't drink them every day or in large quantities at one time. And some carbonated drinks containing caffeine, cola is the most representative, although it has a refreshing effect, but it is generally suitable for adults to drink when they occasionally feel tired and depressed, not suitable for children. For low-calorie carbonated drinks, because of their low calories and low sugar content, they are more suitable for diabetics or people who have special requirements for sugar and calorie intake.
What harm does drinking water with a lot of scale do to the body for a long time? However, the human body has a self-regulation system, and it can be controlled if it is not excessive every day. Just don't let the inner ring system collapse, which is generally impossible. In China, this is a survival factor of 9. Nine people race. . . . Ha ha laugh
