There are many types of water on the market today, so what is the best water to drink?
Distilled water in the human body needs trace elements are removed at the same time, the original part of the organic matter in the water has not been removed. Long-term drinking will not only lack of certain trace elements, and may be some organic drink into the body, not healthy. Magnetized water is water after magnetic field effect. It is said to have softened the heart, cerebral blood vessels, prevention and treatment of gall and kidney stones, but experts emphasize that this has to be verified after long-term practice. Mineral water is groundwater from deep underground flowing through certain rocks. The trace elements in it have the health care components needed by the human body. However, many mineral water does not meet the health requirements, even if the health of the mineral water, due to the different physical conditions of the human body, the types and quantities of trace elements required are also different, so the trace elements and ions of mineral water is not beneficial to everyone. Pure water refers to the water after purification treatment. Normal people drink pure water appropriately, helps the microcirculation of the human body. However, during the treatment process as it not only removes the bacteria, viruses, pollutants and other impurities in the water, but also removes the trace elements and minerals that are beneficial to the human body. It is advisable to make a drink and drink it occasionally, not for a long time.
What are the standards for drinking water?
Drinking water refers to water used for human consumption and daily life, including water for personal hygiene, but excluding water used for aquatic organisms (e.g. fish farming) and water used for special purposes. The most recent standard on drinking water is the "Hygienic Standard for Drinking Water for Domestic Use" issued in 2006, which is based on three main aspects to guarantee the safety and hygiene of drinking water, i.e., to ensure that drinking water has good organoleptic properties; to prevent outbreaks of water-borne infectious diseases; and to prevent acute and chronic poisonings as well as other health hazards. The indicators for controlling the health and safety of drinking water include four major categories: microbiological indicators; organoleptic properties of water and general chemical indicators; toxicological indicators; and radiological indicators.
What happens when there is a bad odor or taste in the water?
When the water is found to have a strange odor and taste, it can no longer be consumed. You should immediately report the situation to the health supervision office in your district, and the CDC at all levels can test the quality of the water. Only after the cause of contamination is determined and the odor and taste are eliminated can you continue to drink the water. Strange odor and taste in water may be due to chemical or microbial contamination of the water. Such as iron, copper, manganese or zinc ions in the water when the content of water will have a taste; actinomycetes and algae can make the water produce a bad smell; when the water has a high content of phenols, chlorination disinfection, chlorophenols can be produced, there is a bad smell.
Can I still drink the water when I find it has a color?
Safe drinking water should be colorless, when the water has a color, it can no longer be drunk. You should immediately report the situation to your district health inspection office, and CDCs at all levels can test the quality of the water. The CDC can test the quality of the water and determine the cause of the contamination and eliminate the coloration before drinking the water. The color of water may be caused by colorful substances (such as humic acid), metals, or highly colored industrial wastewater. The Hygienic Standard for Drinking Water states that the color should not exceed 15 degrees.
What to do when water appears cloudy?
Safe drinking water should be clear and transparent, when the water becomes turbid, it can no longer be consumed. The situation should be reported immediately to the health supervision office in your district, and the CDC at all levels can test the quality of the water. Drinking can only be resumed after the cause of the contamination has been determined and the water has been clarified. Turbidity is caused by particulate matter (such as clay and silt), plankton and other microorganisms in the water. Turbid water not only affects the sensory effect, but also affects the disinfection effect of water, so that the dose of disinfectant is increased. Living Drinking Water Health Standards" stipulates: turbidity should not exceed 1 NTU, special circumstances do not exceed 3 NTU.

(3) Purchase of water dispensers to have health administrative departments to issue health permits approved products. Bucket of water to have a health license of the water plant produced by the batch number of the bucket of water.
Some neighborhoods have installed drinking water systems that are really safe and hygienic for direct drinking?
Some neighborhoods in the municipal water supply based on the installation of water purification equipment, the output of pure water or clean water supply users to drink directly. In order to ensure the safety of drinking water, first of all, the user needs to ask the developer for the water purification equipment, "health permit approval", and secondly, the user should require the developer to run the initial installation of the equipment after the water quality testing, inspection before being put into use. Water purification equipment has high health requirements, the need for regular replacement of purification components, so users should also require the property or the developer of regular (monthly or quarterly) on the status of water quality testing.
What are the causes of microbial contamination of bottled water?
(1) poor disinfection in the production process; (2) cleaning and disinfection of barrels is not complete; (3) filling process pollution; (4) barrels of water and drinking fountains supporting the use of drinking fountains, resulting in contamination of the drinking fountains out of the water system.
What if the drinking water is abnormal?
①. First of all, to determine whether it is only their own home water problems? If so, you need to find their own reasons, can not find the reason to pay the fee commissioned by the CDC water quality testing. ②. If not only their own home drinking water anomaly, the residential buildings, neighborhoods have the same abnormalities, then you should immediately contact the District Health Supervision, reaction to the situation, requesting assistance to solve the drinking water pollution problem.
What are the household water purification devices?
①. Water purifier: municipal tap water as a source of water, after further treatment of the water contains some harmful substances or microorganisms removed from the drinking water processor. According to the different harmful substances in the water, the choice of different filter water purifier. ②. Water purifier: municipal tap water as a source of water, reverse osmosis way to remove all the substances in the water drinking water processor, which removes harmful substances in the water at the same time, the water will be beneficial to human health substances are also removed. ③. Water softener: the market sells such products through the ion exchange of calcium and magnesium ions contained in the water to remove, so as to reduce the hardness of the water to achieve the purpose of reducing the hardness of the water at the same time, increasing the concentration of sodium ions in the water, thereby increasing the incidence of cardiovascular disease.
What is secondary water supply?
Secondary water supply refers to the water unit will come from the city centralized water supply system of drinking water, after storage or reprocessing (filtration, softening, disinfection), through the pipeline to the user of the water supply method.
What are the secondary water supply facilities?
Including storage tanks (water tanks), water intake pipes, overflow pipes, drainage (discharge) pipes, entry holes, ventilation holes, water treatment and water disinfection equipment.
What factors can cause secondary water supply pollution?
(1) unreasonable design: secondary water supply pipeline, and fire water pipeline, industrial water pipeline connection; storage tank (water tank) overflow pipe and drain pipe directly connected to the sewer line; water tank water without preventing secondary pollution disinfection facilities; water tank wall coating does not meet the hygiene requirements, paint peeling and dissolution. (2) Unreasonable structure of water tanks: the inner wall of cement water tanks is not smooth; steel tanks are rusty; there is no cover or lock for the observation hole of water tanks; there is no ventilation hole for water tanks; and there is no protective netting for the opening of overflow pipes. (3) poor management: not regularly cleaned, disinfected; disinfection facilities can not function properly; the environment around the water tank is dirty, the water tank cover is not tight, etc..
Definition and classification of products related to drinking water health and safety
Where in the process of drinking water production and water supply in contact with drinking water materials, plastics and organic synthetic pipes, fittings, protective coatings, water treatment agents, descaling agents, water quality treatment and other new materials and chemicals known as products related to drinking water health and safety products (water-related products). Currently on the market mainly include the following products: electric kettles, drinking fountains, water purifiers, water purifiers and water softeners and various types of pipes, fittings, etc.
The market should pay attention to the purchase of water-related products
The market sells electric kettles, drinking fountains, water purifiers, and other products of a wide range of more varied brand names, the quality of health is also different. Purchase, the first thing to look at the product with or without the health administrative department issued a health license approval. In the purchase of such products, but also to check the product brand, model and approval is consistent, such as can not provide inspection reports, consumers should be careful when buying. In addition to the purchase of water purifiers, you should also look at its instruction manual to see whether the function of its publicity and their own needs in line. In the purchase of bottled water, you should buy large enterprises, well-known brands of products, because the production of such enterprises is more formal, to ensure the quality of the production process, to ensure that the water is safe and hygienic. Because the barrels of bottled water are used repeatedly, some small water stores recovered barrels without disinfection directly into the tap water, can not guarantee the health of the water. Therefore, when purchasing bottled water, you should first inquire about the address and telephone number of the manufacturer to prevent the purchase of counterfeit and shoddy products.
Drinking fountains in daily use should pay attention to the problem
Drinking fountains, first of all, to ensure that the use of hygiene and safety of the barrel water, and secondly, should be regularly cleaned, disinfected drinking fountains. The company responsible for cleaning the drinking fountains use disinfectant drugs, should be able to issue health and safety certificates (provincial health department of health quality inspection report), otherwise it may cause contamination of the drinking fountains. After disinfecting the water dispenser, it should be rinsed several times to prevent the disinfectant from remaining in the dispenser. In addition, the period of use of barrel water should not be too long (not more than 7 days), otherwise it is easy to cause the growth of bacteria in the water.
Water softener in use should pay attention to the problem
Water softener can remove the hardness of the water, so that the water to soften. In high hardness areas after the use of water heating can make the scale produced by the reduction of tea taste better, but because it reduces the hardness of the water at the same time will make the sodium ions increase, long-term drinking can lead to an increase in the incidence of cardiovascular disease, so if the local water hardness is not high then do not use water softeners. As far as Beijing is concerned, the high hardness of water in the western part of the city can be considered to use a water softener, but because it has side effects, it is recommended not to drink softened water for a long time, especially the elderly.
Water purifier in use should pay attention to the problem
