The Rio Olympic Garden "farty smelling green pool" was found to be caused by a mistake by a dealer



It is reported that the "mysterious green pool" that occurred at the Rio Olympics where a hot fight by the top athlete is spreading every day is reported to have been stinky, and it is expressed as "a farty smell" It was up to the players. At a certain point, we stopped using the pool itself and exchanged the water, but it is clear that it was inappropriate for the drugs that were introduced by the pool water quality management company.

The pool suddenly appeared at the Rio Olympics venue and became a hot topic was the pool where the color of the water changed to green overnight. The situation occurred in the two pools at the "Maria Lenk Swimming Center" where water sports and dive events are held, the color of the water suddenly turns green from August 9 to 10, and it turns muddy I fell into the situation.


The cause was that the occurrence of "algae" occurred in the water later, but from the players who actually compete, there are situations in which protest voices such as "stinky" "eye" hurts " , And the organizing committee of the convention was supposed to investigate the causes and measures.

In response to this situation, the organizing committee announced in a statement that algae breeded due to heat and insufficient ventilation in the hall and the color changed, and as a result of the water quality tests, announced that the players found no risk It was. However, in sports such as synchronized swimming which acts in pairs due to the occurrence of muddiness while also observing smell and eye pain, players will fall into a situation where they can not perform.

As a result of the obstacle to the management of the competition, the event organizer announced on August 13 that the trial to purify the water ended in failure and replaced the water of 3.73 million liters. This measure will be taken at the 50 meter pool where the water ball is playing, and synchronized swimming is also held from this 14th on the 14th, so the organizer judged that clear water is necessary .

And the cause which became the origin of this case is clarified. It turned out that it was "hydrogen peroxide" that was introduced by a local dealer who underwent management of the pool that caused algae to be generated in the water and turned into muddy green.

Chlorine based disinfectants are most widely used to manage the quality of the pools, and many people have seen that chlorine is also being used in schools and other pools. However, it was the cause of the incident that adding hydrogen peroxide to chlorine weakened the effect of chlorine, resulting in decreased disinfection power, leading to the generation of algae.

However, introducing hydrogen peroxide itself to improve water quality is not a wrong choice. The mistake this time is in the place where hydrogen peroxide has been added to the pool where chlorine has already been used. This supplier introduced 160 liters of hydrogen peroxide on August 5, which was causing water quality deterioration.

The water quality improvement did not go well and the organizer who declared "Give up" was forced to replace the water of the competition pool with the water of the nearby practice pool. This work took 6 hours to drain the current water and 4 hours to transfer the new water, which took a total of 10 hours.


Besides, at the Rio Olympic Games, we have problems such as serious deterioration of the water quality of the sea where games such as yacht race scheduled to be held in the future will take place, It is likely to gather.
