After all, Wuhan is rich in rivers, lakes and groundwater, with many water sources and little pollution.
The water sources in Wuhan are all directly drawn from the Yangtze River and the Han River, all of which are tap water. After treatment, the water quality is still good.
Question 2: I want to ask where the water quality is poor and the scale is serious. * * * Six cities in Shandong (Jining, Zibo, Linyi, Jinan, Weihai and Taian), three cities in Guangdong (Chaozhou, Zhuhai and Shaoguan), three cities in Inner Mongolia (Wuhai, Erdos and Hohhot), four cities in Fujian (Ningde, Quanzhou, Fuzhou and Longyan) and Jiangxi 1 city (Ganzhou).
Analysis and summary of regional water quality in China: main pollution impurities (such as heavy metals, etc. ) In all provinces and regions, the water source is turbid, and there is scale in Yingkou, Liaoning, but it does not affect the sales of Huludao. There are many impurities, silt and rust, and the water quality is not very good. Fushun is muddy, a little yellow and has a high hardness. There is sand and rust in Dalian, and the hardness is a bit high. Heavy metals are rising in the sun, and a large amount of enterprise sewage is discharged into rivers. Excessive use of chemical fertilizer makes Fuxin water hard. The sediment content in Anshan is relatively high, and some of the domestic sewage in Shenyang contains excessive iron. Bleaching powder Jinzhou has heavy taste, poor water quality and high hardness. Panjin has many rust deposits and high hardness. Liaoyang is yellow and smelly. Beijing beijing has a high hardness and Tianjin has a bad smell. Yellow River cement sand in Putian, Xiamen and other places in Fujian has high turbidity and hardness, and high bacterial and viral pollution. Bleaching powder has a strong taste and moderate hardness. Smelly Fuzhou tastes bad, heavy metals exceed the standard, calcium and magnesium ions exceed the standard, residual chlorine is serious, hardness is moderate, Ningde scale is heavy, Quanzhou turbidity, odor and hardness are moderate, scale is heavy, Fuzhou turbidity and hardness are moderate, scale is heavy, Longyan turbidity, scale and bleaching powder are heavy, and water hardness is high; Nanping has moderate turbidity, chlorine and hardness. Zhangzhou has high turbidity and high hardness. Wenzhou, Zhejiang tastes bad. Residents mainly drink large barrels of water, mainly heavy metals exceeding the standard. High turbidity, serious residual chlorine and moderate hardness. Taizhou has more sediment content and moderate hardness. The residual chlorine in Hangzhou is serious. The hardness is higher. Wenling has more sediment content, Zhoushan has higher hardness. The water quality of Quzhou tap water is better. Guizhou Guiyang has moderate hardness. Shanghai has sediment, odor and rust (the tap water smells like sewage, which has been improved). The local water quality in Suzhou, Anhui Province contains more fluorine. The local water quality in Wuhu is very good, and there is no large-scale pollution. The main iron and manganese in Tongling exceeded the standard, and the scale in Anqing was serious. Most of the impurities in the water are phosphorus and nitrogen in Bozhou, the sediment in Fuyang exceeds the standard, and a small amount of iron is found in Huainan, Hefei, mainly in the rural market of Wuhan, Hubei, and microorganisms are the main ones in Suizhou, Hubei, with high bacterial virus content. Xiaogan work area has more polluted sewage. Rock is hard, heavy metal Yichang is turbid, and Yellowstone is hard and turbid. The hardness of microorganisms, sediments and Zhenjiang water in Suzhou, Wuxi and Changzhou in Jiangsu Province is relatively high, mainly calcium and magnesium exceeding the standard. Yangzhou is dominated by microorganisms, with high bacterial virus content and heavy pollution. Taizhou is rich in sediments and algae. The water quality in Yancheng is hard. The main reasons are that calcium and magnesium exceed the standard, the sediment content in Nantong is high, heavy metals in Xuzhou exceed the standard, calcium and magnesium ions exceed the standard, the hardness in Ji 'an, Jiangxi Province is higher, and the water hardness in Anfu County is higher. Scaling in Ganzhou is a common phenomenon, and the water hardness in Pingxiang, Jiujiang is relatively high. Nanchang is mainly the secondary pollution of water supply network, such as iron and manganese exceeding the standard in Yichun, heavy mud in Xinyu, good overall water quality in Shangrao, yingtan, and high hardness in a few places. The scale of Guang 'an in Sichuan is low, which is suitable for ultrafiltration. The distribution of water quality in Baoding City, Hebei Province is uneven. Some are mainly groundwater and some are mainly surface water, and the hardness of water is relatively high, reaching about 200. Hengshui groundwater is in good condition with high hardness. Chengde groundwater has good water quality, less pollutants and is clean. Langfang is generally good, with water hardness 180 and low sediment content, and the water quality in some areas smells bad. The water hardness in Zhangjiakou City is very high. Cangzhou water has a high hardness, Handan water has a high hardness and Xingtai water has a high hardness. Golden ... >>
Question 3: Is the tap water in Wuhan soft or hard? Wushui company belongs to surface water treatment, and its hardness is not very high, so it should belong to soft water.
It is worth mentioning that the tap water industry does not distinguish soft water from hard water in this way, just saying how hard the water is, and there is no concept of soft water.
Question 4: I need a report on the quality of tap water in Wuhan for your reference. Thank you! Is the drinking water source in Wuhan all Yangtze River water? 20 points, Wuhan uses all the Yangtze River water.
Baishazhou Waterworks, Pinghu Sluice and Yujiatou Waterworks all use Yangtze River water.
Zongguan Waterworks uses Hanjiang River water, which is also equal to Yangtze River water.
The report you want can be found on the underground pipeline network to check for water leakage.
Question 5: Which is healthier, Wuhan tap water or bottled water? We all know that tap water will be precipitated, disinfected and filtered, but the current tap water treatment technology will still bring disinfection by-products, such as trihalomethanes (THMs). Although tap water meets the drinking water standard of our country, it will cause cancer after a long time, and the tap water passing through the pipeline will cause secondary pollution of tap water, because there will be red worms, rust, asbestos and heavy metals in the city's tap water pipeline for a long time.
Barreled water is pure water after reverse osmosis, electrodialysis, distillation and resin softening. There is no mineral in this kind of water, which is not good for your health if you drink it for a long time, and bottled water will produce bacteria after being put on the water dispenser for about four or five days. I suggest that you can install a water purifier at home, which can filter harmful substances in tap water.
Question 6: How much is a ton of water in Wuhan? Water price of Wuhan residents
Primary supply price 1.52+ sewage treatment fee 0.8= household price 2.32.
The monthly water consumption of households (with a registered population of 4 or less, the same below) is less than 25 cubic meters (inclusive); The monthly per capita water consumption (the registered population is more than 5, the same below) is less than 6.25 cubic meters (inclusive).
Secondary water supply price 2.28+ sewage treatment fee 0.8= household price 3.08.
Monthly water consumption of 25 cubic meters (excluding the number) to 33 cubic meters (including the number) of water; The monthly per capita water consumption is 6.25 cubic meters (exclusive) to 8.25 cubic meters (exclusive).
Tertiary supply price 3.04+ sewage treatment fee 0.8= household price 3.84.
Household monthly water consumption exceeds 33 cubic meters (excluding the number); The monthly per capita water consumption exceeds 8.25 cubic meters (excluding this figure).
Non-resident water use in Wuhan
Supply price 2.35+ sewage treatment fee 0.8= household price 3. 15.
Water for special industries in Wuhan
Supply price 9+ sewage treatment fee 0.8= family price 9.08.
Question 7: What is the standard water pressure of Wuhan tap water? Some reference information about water pressure
1. According to the national regulations, the water supply pressure of residential buildings should not exceed 0.35MPa, that is, 35 meters, after deducting the head loss of sanitary ware and pipelines at the most unfavorable point 10 meter. Finally, it depends on the pressure provided by local water supply units.
2. It is generally considered that 0. 1 MPa = 10 m, and the supply pressure at the end of the pipe network stipulated by the state is 0. 14Mpa. According to national standards and industry social commitments, the pressure of tap water pipe network reaches 0. 14 MPa, which is considered as qualified. In layman's terms, it means that as long as the pressure of tap water can guarantee the height of four floors. (Upon inquiry, Shanghai is 0. 16Mpa). If you live in low terrain, the water pressure at the end of the pipe network may increase. So it depends on the floor where you live to judge the water pressure in your home. However, if you live in a small high-rise building and tap water is supplied by secondary pressure, the surrounding water pressure will increase greatly. You can ask the property to see what range they will control the water pressure.
3. What is the concept of six kilograms of water pressure? Ppr pipe can bear 6 kilograms of water pressure. What is the water pressure of the normal tap water pipeline? It is this pressure that can pump water to 60 meters high, that is, the pressure generated by a 60-meter-high water column. Now almost all owners use PPR water pipes for decoration, so it is no problem to bear the pressure above 0.6Mpa!
According to the Code for Planning of Urban Water Supply Project (GB50282-98) issued by the Ministry of Construction, the water supply pressure of urban water supply network should meet the requirements of 28m service head at the user connection point.
If you are satisfied, please adopt it!
Your adoption keeps me working hard!
Question 8: What is the hardness of water quality in Wuhan and Shanghai respectively? If it is geological water, it is generally within 200 mg/L.
Question 9: I am pregnant. The tap water in Wuhan tastes strong. Can I drink it after boiling? The specific situation is like this.
Question 10: Can I drink the tap water in Wuhan when it is boiled? The water produced by the waterworks meets the drinking standard. However, this does not mean that it is standard drinking water.
There are two reasons:
(1) Although chlorine can kill harmful substances such as pathogenic microorganisms in the production of tap water, adding chlorine itself will cause new chemical pollution. Chlorine can react with organic matter in water to form chloroform, which is a carcinogen. At the same time, chlorine also destroys nutrition and easily leads to heart disease.
(2) In the water supply network, long-distance pipeline transportation, old and rusty pipelines, unclean water tanks and reservoirs in urban high-rise buildings or not disinfected after years of use can all cause secondary pollution. Secondary pollution makes bacteria, viruses and algae multiply in large quantities, while the original chlorine and chloride, rust, heavy metals and radioactive substances make the water turbid and smelly, which is harmful and useless.
So tap water is not standard drinking water. In the increasingly polluted environment, we must have strict standards for the water we drink in our bodies. Returning to the true nature of water, drinking pure water meets the needs of human body, and drinking raw water is more beneficial to people's health than drinking boiled water. Because boiled water loses too much oxygen, drinking boiled water is not conducive to oxygen supply to the human body.
Maybe a friend will say, I have been drinking tap water all my life, and my body is still very good.
Actually, it's not. First of all, human diseases are an accumulation and gradual process. If you don't drink or drink less unclean water, you will definitely be healthier than you are now. Secondly, the current water environment cannot be compared with that of a few years ago. In the past, water pollution mainly came from organic matter and dirt in nature, and the main pollutants were bacteria and viruses. Therefore, boiled tap water can basically achieve the purpose of disinfection. As we mentioned above, modern water pollution is mainly chemical pollution and heavy metals in industrial wastewater, which cannot be removed by boiling water. Therefore, boiled water is not standard drinking water.
