夏天到了，你用什么消暑？冰凉可口的饮料？嗡嗡作响的空调？还是清凉避暑的泳池？游泳池是除空调房外，人们的第二个避暑天堂。在你在水中欢腾，享受泳池的清凉时，有没有想过，泳池里有一群起舞在池水中的化学物质，它们就是游泳池水中的“秘密武器”。

As summer is coming, what do you use to cool down? An icy and delicious beverage? A buzzing air conditioner? Or a cooling swimming pool? The swimming pool has become the second summer paradise for beating the heat after air-conditioned rooms. While you are enjoying the coolness of the pool, have you ever thought about the group of chemicals dancing in the pool water? They are the "secret weapons" in the pool.

一、泳池的“白衣骑士”——消毒剂The "White Knight" of the Pool - Disinfectant

氯，是泳池最常用的消毒剂，它就像“白衣骑士”，守护着泳池的的守护，如果没有它游泳池将会变成细菌和病毒的温床。氯，通过化学反应，杀死水中的有害物质和细菌，确保水质清洁无虞。但也要注意，这位骑士也有它的“脾气”，过度使用氯，会刺激游泳者皮肤和眼睛，导致皮肤红疹、眼睛肿痛等过敏症状。所以，管理员们会使用专业设备和试剂，精准控制氯的添加量，确保大家在享受清凉的同时，也能远离刺激。

The most popular disinfectant in swimming pools, Chlorine acts as a "white knight" guarding the pool. The swimming pool would become a breeding ground for bacteria and viruses without it. Through chemical reactions, Chlorine kills harmful substances and bacteria in water and ensures the cleanliness and safety of the water. However, please note that this knight is not without its battle casualties. Excessive chlorine can irritate the swimmer's skin and eyes, leading to allergic symptoms such as skin rash, eye swelling and pain. The managers often use professional equipment and reagents to accurately control the amount of chlorine, which make everyone enjoy coolness without irritation.

二、泳池的“美容师”——澄清剂The "Beautician" of the Pool - Clarifier

常游泳的你浮潜在水下时，应该都有过通过泳镜看到水中漂浮杂质的经历。一想到这些漂浮物都有可能在你换气张嘴的时候，进入你的体内，真是太让人恶心了。这个时候，泳池就得请出澄清剂这位“美容师”了。凝聚剂（如明矾）和絮凝剂（如聚丙烯酰胺）是游泳池最常使用的澄清剂。这些化学物质不断与悬浮颗粒结合，形成越来越大的颗粒团，最后用过滤设备将其从水中去除。让游泳池的水变得清澈透明。

If you are a frequent swimmer, I’m sure you’ve seen the water’s impurity when you dive in with your goggles. It's really disgusting to think that these floating objects could enter your body when you are choked by water. It’s time to hire a clarity "beautician." Coagulants (such as alum) and flocculants (such as polyacrylamide) are the most popular clarifying agents in swimming pools. These chemicals continuously combine with suspended particles to form larger and larger particle clusters, which are finally removed from the water by filtration equipment, making the water in the swimming pool clear and transparent.

三、泳池的“酸碱平衡师”—pH调节剂The "pH Balancer" of the Pool - pH Adjuster

泳池水质的pH值与游泳的舒适度关系密切。池水pH值低说明池水呈酸性，这样就会腐蚀游泳池设备和游泳者的皮肤；池水的pH值高说明池水呈碱性，对皮肤和眼睛就会有强刺激。盐酸或氢氧化钠是泳池最常用的pH调节剂。就像一位称职的“酸碱平衡师”，它会根据水质酸碱度，相应调整酸碱调节剂的用量，使游泳池的水质时刻保持酸碱平衡，让泳池中的我们游得更加畅快。

The pH value of the water in a swimming pool is the key point for the comfort of swimming. Low pH value makes the water acidic, which leads to the corrosion of swimming pool equipment and is harmful to the skin of swimmers; high pH value makes water alkaline, which can also irritate the skin and eyes. Hydrochloric acid or sodium hydroxide is the most popular pH regulator in swimming pools. Being a competent acid-base balancer, it adjusts the acid-base to maintain balance, which makes are swimming experience a happy one in the pool.

四、泳池的“健康守护者”—其他化学物质The "Health Guardian" of the Pool - Other Chemicals

除了上述的三种化学物质外，游泳池还可能添加其他化学物质来进一步改善水质和游泳体验。十二烷基氯化铵是一种阳离子表面活性剂，可以除臭和缓蚀，还可以增强水的润滑性；而氯酸钠和高锰酸钾是做常见的脱色剂，可以去除水中的异味和颜色；一些高档场馆，还会在泳池水中添加矿物质和维生素，为游泳的人提供提供额外的健康和护肤效果。

In addition to the three chemicals mentioned above, swimming pools may also have other chemicals added to further improve the water quality and swimming experience. Dodecyl ammonium chloride is a cationic surfactant that can deodorize and inhibit corrosion, as well as enhance the lubricity of water; Sodium chlorate and potassium permanganate are common decolorizing agents to remove odors and colors from water; the best swimming pools add minerals and vitamins to the pool water to provide additional health and skincare benefits for swimmers.

五、泳后小提示Some tips after swimming

虽然有这些化学物质像“秘密武器”一样默默守护我们的游泳安全，但泳后清洁，也是确保身体健康的重要手段，不能忽视哦。游泳后，使用温水淋浴冲洗全身，确保将游泳池中的氯和其他化学物质冲洗干净。要选择具有广谱抗菌效果的抗菌沐浴露和洗发水，这有助于杀死皮肤和窝藏在头发里面的细菌。游泳后，还应刷牙漱口，使用漱口水或清水漱口清洁口腔，避免游泳池水中的细菌进入胃肠道。如果眼睛有不适感，还可以适当使用具有消炎杀菌功能的眼药水，如氯霉素眼药水，以预防眼睛感染。上述过程完成后，穿上干燥洁净的衣服，再抹上适合敏感肌肤的护肤品，你就干干净净、满血复活啦！

Although these chemicals silently protect us like "secret weapons," don’t forget post swimming cleanliness is also important to ensure physical health. Take a warm water shower after swimming to rinse the chlorine and other chemicals off of your body. Choose antibacterial shower gel and shampoo with broad-spectrum antibacterial effects to make sure bacteria on the skin and hair can be killed. Brush your teeth and rinse your mouth with mouthwash to prevent bacteria getting into your gastrointestinal tract. If your eyes feel uncomfortable, eye drops with anti-inflammatory and antibacterial properties would be helpful. After all of the above, put on dry and clean clothes and apply skincare products. You will be clean and refreshed!
