1. What is domestic water for residents?
Domestic water refers to the water needed by human daily life. Including urban domestic water and rural domestic water. Urban domestic water consists of residential water and public water (including service industry, catering industry, freight industry, post and telecommunications industry and construction industry), while rural domestic water includes livestock water in addition to residential water.
Hard water: refers to water with high calcium and magnesium ion content. Spring water, deep well water and seawater are all hard water. When water flows through land and rocks, it will dissolve a small amount of mineral components, and calcium and magnesium are the two most common components, which will harden the water quality. The more mineral components such as calcium and magnesium in water, the greater the hardness of water. Long-term consumption can cause hepatobiliary or kidney calculi. Soft water: Water that contains no or less soluble calcium and magnesium compounds is called soft water. Natural soft water generally refers to rain, snow, rivers, rivers and lakes. Softening hard water refers to softened water obtained by reducing the contents of calcium and magnesium salts to1.0 ~ 50 mg/L. We usually refer to the content of calcium and magnesium ions in water as "hardness". The hardness of 1 degree is equivalent to 10 mg of calcium oxide per liter of water. Water below 8 degrees is called soft water, water above 17 degrees is called hard water, and water between 8- 17 degrees is called moderately hard water. Drinking water rich in calcium ions and magnesium ions in moderation is beneficial to health. Magnesium ion is helpful to activation in human body, and it also has the function of stabilizing neuromuscular conduction. Therefore, when the concentration of magnesium ions in the body is too low due to insufficient intake of magnesium ions, arrhythmia and abnormal vasoconstriction are prone to occur. Normal people must take at least 350 mg of magnesium ions from food or drinking water every day to stay healthy. Because magnesium ions absorbed from food are easy to combine with cellulose in food, but not easily absorbed by human body, the most effective way to increase the absorption of magnesium ions in the body is to take them from drinking water. Calcium and magnesium ions are essential nutrients for human body every day. If the water has a certain hardness, you can supplement a certain amount of calcium and magnesium ions by drinking water. If you take soft water for a long time, you need to supplement it through other channels. But the hardness of water is too high or too low, because the hardness of water is closely related to some diseases. In areas with high water hardness, the incidence of cardiovascular diseases is low, but the incidence in kidney calculi increases with the increase of water hardness. China is mostly soft water in the south and hard water in the north. The standard of drinking water in China is that it cannot exceed 25 degrees, and the most suitable hardness of drinking water is 8- 18 degrees, which belongs to mild or moderate hard water. The hardness of water is also related to taste. Hard water is refreshing, and most mineral water has high hardness, which makes people feel fresh and delicious, while soft water is tasteless. But making tea and coffee with hard water will affect the taste. Some food processing water is special. Hard water will affect food processing, and it is easy to cause protein precipitation, inorganic salt precipitation or difficult cooking. Soft water is more suitable for beverages. Boiler water should generally soften hard water, otherwise too much scale will cause accidents.
2. How much is the water fee in Hohhot?
Water price:
1. Domestic water consumption of residents: 2.80 yuan/m3;
2. Administrative water consumption: 3.90 yuan/m3;
3. Industrial and commercial water consumption: 4. 10 yuan/m3;
4. Water for hotels, restaurants, restaurants, etc. : 4.60 yuan/m3;
5. Water consumption of bathing industry: 60 yuan /m3.
Note: Water fee includes water resource fee, tap water fee and sewage treatment fee, in which water resource fee and tap water fee are uniformly priced.
Domestic water for residents:
Residents' domestic water will continue to be subject to the ladder water price, and the water consumption and water price will be arranged in three levels. Residents who have implemented meter reading to households:
The first-class water quantity is set at 8 tons/household and below, and the price is adjusted from 2.6 yuan to 3.38 yuan;
The secondary water volume is 8- 12 tons per month, and the price is adjusted from 3.9 yuan to 5.07 yuan;
The third-class water volume is more than 0/2 ton per month/kloc, and the price is 6.76 yuan.
Residential users who have not yet implemented meter reading to households will not implement stepped water price measurement for the time being.
Other water use:
The price of domestic water for all kinds of schools will continue to be uniformly implemented.
The water consumption of municipal public facilities such as sanitation and greening will not be adjusted, and will continue to be implemented at the current price of 2.00 yuan/ton.
Non-resident water price is uniformly adjusted to 6.9 yuan/ton. The price of water for special industries is adjusted from 15 yuan/ton to 19.5 yuan/ton.
Note: The sewage treatment price in the urban water supply price is not included in the price increase base for calculating the ladder metering water price, and the sewage treatment fee is still charged according to the current regulations.
To sum up, water price: domestic water consumption: 2.80 yuan/m3; Management water: 3.90 yuan/m3; Industrial and commercial water consumption: 4. 10 yuan/m3; Water for hotels, restaurants, restaurants, etc. : 4.60 yuan/m3; Water consumption of bathing industry: 60 yuan /m3. Water fee collection includes three parts: water resource fee, tap water fee and sewage treatment fee, in which water resource fee and tap water fee are uniformly priced.
