　　1. How to judge the quality of tap water?

　　Take a look: Fill a glass of water with a transparent glass, and look at the light to see if there are any fine substances suspended in the water. After standing for several hours, observe whether there are sediments at the bottom of the glass. If there are, it indicates that there are many suspended impurities in the water and the water quality is poor.

　　Second smell: take a glass of water as far away from the faucet as possible, and smell whether there is bleach (chlorine) with your nose. If you can smell the slight bleaching powder (chlorine), it means that there is residual chlorine in tap water, which is normal and can be used safely.

　　Three views: make tea after boiling with tap water, and observe the tea after a period of time (several hours) or overnight. If it turns black, the iron and manganese content in the water may be high.

　　Four products: when drinking boiled water, if you feel astringent, the hardness of the water may be high (but it varies)

　　2. What should I do if the tap water is abnormal?

　　The yellowing of tap water is probably affected by the rust on the inner wall of iron water pipes in the water distribution network. Some tap water can be released and used after the water quality is clear.

　　When there are other abnormalities in drinking water, you should immediately call 47565019 to report the situation to the health supervision department, and use water properly or stop using water under its guidance. At the same time, the neighborhood Committee, the property department and the surrounding neighbors should be informed to stop using it; Take 3 to 5 liters of water as a sample in a clean container and provide it to the health inspection department. If you accidentally drink contaminated water, you should pay close attention to whether you feel unwell. If there is any abnormality, you should go to the hospital immediately. After receiving the official notice from the government management department that the water pollution problem has been solved, the drinking water can be resumed.

　　3. How to choose a water quality processor (water purifier)?

　　When choosing a water quality processor, we should grasp three basic principles: first, choose a brand, and the quality of a big professional brand is more reliable. Second, see if there is a health permit approval and a water quality test report from an authoritative organization. Third, look at the type of water quality processor. Water purification should be combined with the actual situation of local water quality. Surface water is mainly used in the south, mainly to remove sediment, biological humus, bacteria and organic matter, while groundwater is mainly used in the north, and consumers pay more attention to scale removal. When purchasing, you should prevent the "magic" effect of various functional water and water quality treatment products and prevent "flickering". When purchasing, you should choose a water purifier according to your own needs.

　　4. How to choose and use the drinking fountain correctly?

　　When purchasing and using drinking fountains, we should pay attention to the following points: First, we should buy drinking fountains with valid hygiene license documents related to drinking water hygiene and safety products. Second, the water dispenser should be cleaned and disinfected regularly, and should not be placed in direct sunlight. Third, the bottled water used in the water dispenser should be drunk as much as possible within one week. It is easy to breed bacteria after a long time. If it has not been drunk for more than 20 days, don’t drink it again. (Huang Huan)
