Advanced indoor swimming pool, generally use the "overflow" cycle of filtering water. In the bottom of the pool there are many fabric outlet, the water overflows through the overflow tank into the balance after the pool (the role is to maintain the pool water circulating system stability). Swimming pool water back through the overflow pipe by gravity back to the balance of pool, then back to the pool for circulating pump.

    A week ago, Yiwu Meihu swimming center water test results came out, so that the public-popping: the total number of bacteria exceeded.

    In Yiwu popular forums, users are questioned mainly in: Swimming Centre Meihu invest 150 million yuan, the first hardware known as the province, the national first-class, if the water quality here, not even cross the border, what is the local swimming pool can swim?

    Insider broke the news: the problem lies in the isolation layer

    Substandard water quality check to see the beginning of the message, an online friend who lives in Yiwu, Jiangdong Street a surprise: as Meihu Swimming Centre is zhejiang's first international diving competitions can be held in the swimming venue, where I only let the children participate in swimming training But the child went to a few days later, the body sometimes feels itchy, she did not pay attention, then the suspect is not and swimming?

    In Yiwu, a work of the health sector insiders said: This is in accordance with international standard facilities for the construction of swimming, diving pool 6 meters deep, pool games, training is also three meters deep water. In order to do the management training young swimmers to the pool turned into a water depth of only 1-1 meters to 5, so in the middle of a separation layer, sinking into the pool under the dirt is difficult to remove and disinfected, it is not water quality a key factor in compliance.

    The Meihu swimming center water is by "overflow" cycle, which is the internal circulation of water, no fresh water to add into the. Aquatics Center a year ago, after put into use, water quality is a day by adding chlorine, alkali and other chemicals and adsorbents maintained.

    Management: popular too busy imperfection

    Meihu Swimming Centre is a full investment in sports facilities, government, property rights owned by state-owned assets management Yiwu limited liability company, entrusted to the Mall branch stadium management group.

    Swimming Centre management org.oasis frankly, such a situation, they are surprised, perhaps overlooked one important area. Swimming Centre has been paid great attention to environmental sanitation, such requests were not allowed to wear bathing slippers into the water to wear a swimming cap. In water treatment, the introduction of the U.S. "dolphin" disinfection purification equipment, "even a hair into the water, but also able to detect it."

    Liu Xiangyang said the government investment Meihu Swimming Centre is a public place, the management is not the ultimate goal of profit. As the facilities good, come here to swim and participate in the training of people is particularly high.

    Is not a lack of fresh water to add? Liu Xiangyang denied, he said the company set the isolation level is professionally operated, able to deal with daily disinfection and cleaning.

    Health monitoring unit: with the concentration of disinfectant

    Yesterday, recheck the situation out, as qualified. If the review and then pass, swimming center will face punishment, while in or to be closed down.

    yiwu city health surveillance brigade Jinke Zhang said that the first test, but related causes and the concentration of disinfectant. Swimming pool is crowded this time of season, out of more than 1,000 passengers a day, many people, but mishandled the concentration of disinfectant.

    Low concentration of bacteria usually fail to aim too high to stimulate the person's mucous membranes will be. Therefore, the pool of water is not more clear, more green, water quality will be better because of excessive chlorine.

    Yiwu city doctors Luogao Jiang said that as a result of swimming pool chlorine too strong swimmers have a "human response to inhaled," also encountered in clinical. Can be seen simply by increasing the concentration of disinfectant to maintain water quality standards, at least in medical practice is not desirable.
