The impressions of Japan we came across in the media, newspapers, magazines, and the Internet when we were young are nothing more than "advanced black technology, sophisticated robots, clean and clean streets, and polite, clean and polite Japanese people." ". Even in a summer camp attended by teenagers from a certain number of countries, Japanese children behaved more independent than children from other countries.
The most impressive thing is that in the propaganda, Japan is so clean that even the toilet is spotlessly clean. The cleaners clean the toilet to the extent that the toilet water can be directly drunk, But is this really the case?
After the opening of the Tokyo Olympics on July 24, there have been many ridiculous things. Except for the hot and humid weather in Tokyo, which caused a female athlete of the Russian Olympic Committee delegation to stun, In the Olympic triathlon competition yesterday, many athletes were directly spit by the water in Tokyo Bay, and even three athletes gave up halfway because they complained that the waters of the competition were as smelly as the smell of toilets. !
This is just the subjective feelings of the athletes. According to the field measurement by professional organizations, the water temperature, water regime and water depth of the Olympic Triathlon-Tokyo Bay, although the water temperature, water conditions and water depth meet the requirements of the competition, but the water quality is not. Surprisingly poor.
Subjectively, the water in Tokyo Bay is turbid, and it is as smelly as the puddle in the toilet. The E. coli in the water is also seriously exceeded. It’s almost on par with the Ganges in India, but what is puzzling is that in our consistent impression, Indians basically do not advertise how clean they are. Known for "clean, civilized, and polite", So why is Tokyo Bay, which can be called "the facade of the first good district" near the Japanese capital, also become a "dung puddle"?
There are many reasons.Next, let's analyze them one by one.
1. Near Tokyo Bay is one of the most densely populated areas in the world. We know that Japan is small in size and has a large population. Most of the small land area is mountainous and hilly, which is not suitable for large-scale population living. Therefore, near the capital Tokyo, a super large city cluster called " Tokyo Metropolitan Area" has formed, and these cities just surround Tokyo Bay. There are 3400 to 37 million people living on more than 10,000 square kilometers of land (the definition of the metropolitan area is different, and the total population varies).
And these 34 million to 37 million people are crowded around the small Tokyo Bay. In addition to work and study, one thing to do every day is " pooping".
Tokyo is one of the most developed cities in the world. Originally, the sewer system should be world-class. After all, in the past propaganda, the streets of Japan have always been spotless, but the dung water produced by more than 30 million people in Tokyo Bay every day But without any treatment, it was directly discharged into Tokyo Bay! The reason is that Tokyo’s sewer system does not have a rain and sewage diversion system. Here we want to explain what is called the urban rain and sewage diversion system.
In cities, rainfall will be directly discharged into the sewer system, while the sewage generated by residents’ life and work will also be discharged into the sewer system. The so-called rain and sewage diversion means that in the sewer system, rainwater and The sewage pipes are separate . Like rainwater pipes, water is formed by rainfall and is basically free of pollution, so it can be directly discharged into rivers, and cities near the sea can be directly discharged into the sea.
It is like sewage. Because it is mixed with highly polluted water such as kitchen waste sewage, toilet feces, etc., it needs to be concentrated in sewage treatment plants for special harmless treatment to avoid pollution to rivers and seas.
seems to be in our country,After years of hard work, basically the big cities have realized the design of rain and sewage diversion system, which maximized the avoidance of sewage pollution to the river.
But what is striking is that as the capital of Japan, a highly developed capitalist country in the world, the Japanese, who has always been known for their clean and civilized nature, even mixed sewage and rainwater from the Tokyo metropolitan area and discharged them directly into Tokyo Bay!
2, The second reason is the unique topographical features of Tokyo Bay . On the map, although Tokyo is a coastal city, Tokyo Bay is covered by land on three sides and only has a small outlet to the sea. This unique topography makes it difficult for the strong winds and waves on the sea to enter Tokyo Bay, although there are many formations. It is a deep water port, but this also makes the "dung water" discharged into Tokyo Bay gather in Tokyo Bay for a long time, and the drainage is not smooth.
3. The third reason is the recent hot and humid weather in Tokyo . People living in rural areas must have experience. In the past, aqua toilets were popular in rural areas. It is better to say when the winter is cold. When the summer is hot and humid, the taste naturally does not need to be described too much;
Recently, Tokyo is suffering from high temperature. The circulation of Tokyo Bay is inherently poor. The hot and humid weather has worsened the reproduction of microorganisms and the diffusion of odors in the sewage in the waters of Tokyo Bay. Therefore, it is reasonable that most athletes participating in triathlons can directly vomit. .
4. The fourth reason is Japan’s sense of responsibility . In fact, the poor water quality of Tokyo Bay was discovered as early as 2017. At that time, preparations were being made for the Olympic Games. It stands to reason that the waters of Tokyo Bay used for competitions can be treated as clean as possible after three years of preparation time. At least there is no smell.
After all, the water used for the game is not the entire Tokyo Bay, but a small part of the water, but whether it is the smelly puddle of Tokyo Bay,It is also the attitude of Japan to deal with nuclear waste water, which fully shows that the Japanese people who have always been "clean, civilized, responsible, and frequent black technology" only exist in the Japanese propaganda.
