First of all, direct drinking water is not a technical problem, but an economic problem. In other words, in fact, it is also possible for China to require waterworks to filter water to the level of direct drinking water, which only increases the cost. Water quality control is not limited to waterworks. Even if the water in the waterworks is clean, it is still a problem whether the water pipes we have laid in these decades are clean or not. Finally, it is also important to directly drink tap water as a percentage of daily water consumption. For example, people in China are still willing to drink hot drinks. For example, most domestic water is not used for drinking. But in the end, it's just a matter of money. The standard of direct drinking water is high and the price is definitely more expensive. Whether the general public is willing to spend more money to buy direct drinking water to wash the toilet is the most fundamental question.

The tap water treatment technology of most waterworks in China is very backward, and the sedimentation and chlorine disinfection methods decades ago are still used. This treatment itself can't meet the standard of direct drinking. Secondly, the pipelines are old, and many trunk pipelines still use cement pipes and galvanized pipes. Decades later, a large number of impurities were deposited in it, which polluted the water quality. Moreover, in order to sample colonies from end users' homes, many waterworks privately increase the chlorine dosage in tap water to make the bacteria meet the standard, but the chlorine seriously exceeds the standard. Solution: China has a large population. If all the standard tap water for direct drinking water is a huge waste, I personally think that water supply by quality can be adopted. The original old water supply pipe is used for non-drinking water, such as washing clothes, mopping the floor and bathing. And re-lay the direct drinking water pipeline for residents to drink. Of course, direct drinking water must use internationally accepted treatment methods, and the water quality is up to standard. This method is suitable for cities, towns and villages with relatively concentrated population. For areas with loose population distribution, household water purifiers can be used to solve the drinking water safety problem. Personal opinion, welcome to discuss, but please don't spray!

I'm afraid the person who asks the question is suspected of "entering the water" Japanese tap water can be drunk directly, but China can! ! ! We have been drinking tap water directly here for decades. We use tap water for cooking, soup and water. Even if you drink cold water directly, you will never have a stomachache or diarrhea! Our water sources here are "Pearl River Source", "Huashan Reservoir", "Shuicheng Reservoir" and "Xiaoxiang Lake", all of which come from deep mountain springs, groundwater and rainwater. The tap water is not polluted, and it is as sweet as mineral water after strict processing and production by the waterworks. The origin of "Yunnan Mountain Spring" is Yimen. We've seen it. Spring water drips directly from the belly of the mountain, and the bottling factory directly bottles it. It can also be drunk directly. If you don't believe me, have a drink and feel it, and then modify the problem of "behind closed doors"! ("Huashan Reservoir at the Source of the Pearl River", the mountains are good and the water is good)

I'm from the Ministry of Water Resources. I have been to Korea before. Their tap water is not clean, but chlorine, which we call bleach, is used for disinfection in most food factories. However, if their dosing standard is set in China, the problem today will be that the bleach in tap water in China exceeds the standard, and it is related to diet. Most people in China drink hot water. If you go to Korea, you can see that ordinary restaurants use tap water. China's population is developing so well and rapidly. Some things should not be as good as what foreign countries say on the internet. I can tell you responsibly that China is no worse than any other country. Our motherland may be worse than foreign countries in some places, but it is still very good on the whole. . .
5. Wonderful answer:
Why can't tap water in China be drunk directly? I've been drinking directly since I was a child, and it's nothing! There is no need for Japan to belittle China to elevate Japan. Japan's standards may be high, but does it not meet the hygiene standards if it is lower than their standards? What logic! It can be seen that the purpose of some boasting in Japan is not to brag about the Japanese at all, but to belittle China instead.
