Do not dry! Whether the bacteria in the swimming pool exceeds the standard or not can be detected by these instruments. The article is that Harveyson has carefully checked the relevant manuscripts and consulted some senior technicians. After a brief review, the rough insights are for reference only. Because now both the manufacturer and the customer have higher requirements for the product, it is very nuanced to understand. It is also true that the situation can be used freely.

 

 

　　游泳池场所卫生标准中规格泳池水中细菌总数应小于等于1000个/mL，也就是说超过这个范围将会对泳客带来不适皮肤过敏、瘙痒、起疹子、尿路感染等等问题。由于市面上检测泳池水中细菌的仪器昂贵。大多数泳池都不是直接检测细菌总数的，而是通过每天检测泳池水中的余氯来保证游泳池水具有消毒能力，抑制水中的细菌，防止交叉感染。

 

　　The total number of bacteria in the swimming pool water in the swimming pool sanitation standard should be less than or equal to 1000/mL, which means that exceeding this range will cause unpleasant skin allergies, itching, rash, urinary tract infection and the like. Because of the expensive instruments on the market for detecting bacteria in swimming pool water. Most swimming pools do not directly detect the total number of bacteria. Instead, they detect the residual water in the pool water every day to ensure that the pool water has the ability to disinfect, inhibit bacteria in the water and prevent cross-infection.

 

　　细菌总数是衡量池水循环净化处理系统运行质量的一个重要指标，也是主要了解池水消毒是否*的有效方法。通过水传播的病源微生物很多，不可直接测定各种病源微生物。为此通过细菌总数和大肠杆菌数这两个指标，可以间接反映出水中病源微生物的密度或致病菌的可能程度。

 

　　The total number of bacteria is an important indicator to measure the quality of the operation of the pool water purification system, and it is also an effective method to understand whether the water disinfection is thorough. There are many pathogenic microorganisms that are transmitted through water, and it is not possible to directly measure various pathogenic microorganisms. To this end, the two indicators of the total number of bacteria and the number of E. coli can indirectly reflect the density of pathogenic microorganisms in the water or the possible degree of pathogenic bacteria.

 

　　如果池水消毒做到位时水中的细菌总数和大肠菌群是能够控制在标准范围内的，那么引起细菌超标主要分两部分来说。

 

　　If the total number of bacteria in the water and the coliform bacteria can be controlled within the standard range when the water disinfection is done, the bacterial over-standard is mainly divided into two parts.

 

　　1. 余氯值过低。导致细菌繁殖。余氯过低直接加药用用药量即能提升余氯值，不过也有出现过这类现象，投加药剂很多氯消毒剂后，检测水中的余氯还是没有提高，不要着急看后面处理方法。

 

　　1. The residual chlorine value is too low. Causes bacteria to multiply. If the residual chlorine is too low, the amount of residual chlorine can be increased directly. However, there have been such phenomena. After adding a lot of chlorine disinfectant, the residual chlorine in the water is still not improved. Don't worry about the later treatment.

 

　　2. 余氯值过高。但水中细菌还是超标。余氯高，为什么细菌还是超标？首先要知道是什么原因导致余氯高的情况下细菌依然超标。

 

　　2. The residual chlorine value is too high. But the bacteria in the water are still exceeding the standard. The residual chlorine is high, why is the bacteria still exceeding the standard? The first thing to know is what causes the bacteria to still exceed the standard when the residual chlorine is high.

 

　　1）pH值高——影响次氯酸和次氯酸根的含量，从而影响氯消毒剂的扩散吸附过程，杀菌效果减弱。

 

　　1) High pH value - affecting the content of hypochlorous acid and hypochlorite, thereby affecting the diffusion and adsorption process of chlorine disinfectant, and the sterilization effect is weakened.

 

　　2）结合性余氯含量过高——水中的有机物、尿素等产生氯胺，会使氯的消毒杀菌能下降，而氯胺就是我们所说的结合性余氯/化合性余氯结合性余氯能够扩散吸附到细菌表面，但是杀菌力弱。

 

　　2) The combined residual chlorine content is too high - the production of chloramines in organic matter, urea, etc. in water will reduce the disinfection and sterilization of chlorine, and chloramine is what we call the combined residual chlorine/combination residual chlorine balance. Chlorine can diffuse and adsorb to the surface of bacteria, but the bactericidal power is weak.

 

　　3）氰尿酸高——只要使用三氯异氰尿酸或二氯异氰尿酸为主要成分的含氯消毒剂，在水解后都含有氰尿酸，而氰尿酸作为稳定剂，它能控制次氯酸一次只生成一定的数量，使药剂中的氯逐渐释放出来，即使在日光照射下，每次也只有很少一部分次氯酸流失。

 

　　3) High cyanuric acid - as long as the chlorine-containing disinfectant containing trichloroisocyanuric acid or dichloroisocyanuric acid as the main component contains cyanuric acid after hydrolysis, cyanuric acid acts as a stabilizer, which can control hypochlorous acid. Only a certain amount is generated at a time, so that the chlorine in the medicament is gradually released, and even in the case of sunlight, only a small amount of hypochlorous acid is lost each time.

 

　　不过在池水中会不断累积，氰尿酸过低，氯消毒剂会很快被挥发消耗掉，但氰尿酸过高，就会失去对氯的缓释作用，让游离性余氯与氰尿酸之间失去平衡，导致游离性余氯的消毒和氧化能力下降，造成菌群、藻类滋生、水发白浑浊。甚至导致氯起不到消毒作用。

 

　　However, in the pool water will continue to accumulate, cyanuric acid is too low, chlorine disinfectant will be quickly consumed by volatile, but cyanuric acid is too high, it will lose the sustained release of chlorine, let free residual chlorine and cyanuric acid Loss of balance leads to a decrease in the disinfection and oxidizing ability of free residual chlorine, resulting in the growth of flora and algae and the turbidity of water. It even causes chlorine to fail to disinfect.

 

　　4）温度低——温度会影响氯消毒剂的扩散速度，从而影响氯消毒剂的杀菌性能。温度越低，消毒剂的扩散速度越慢杀菌效果越差。一般对室内恒温泳池、洗浴场所等影响较大。

 

　　4) Low temperature - temperature will affect the diffusion rate of chlorine disinfectant, thus affecting the bactericidal performance of chlorine disinfectant. The lower the temperature, the slower the diffusion rate of the disinfectant and the worse the sterilization effect. Generally, it has a great influence on indoor heated swimming pools and bathing places.

 

　　5）总溶解性固体（TDS）高——总溶解固体是指水中全部溶质的总量，而TDS值越高，表示水中含有的溶解物越多，对于长期不补水的池子，TDS随着时间累积，泳客带入的污染物以及投加的药剂逐渐在池水中累积，会导致TDS过高，影响氯消毒剂的扩散吸附过程，从而影响氯消毒剂的杀菌效果。常见的是在死海池中，由于盐分高，水中的TDS高，氯的杀菌效果受限，导致容易长藻水浑等问题，其游泳池的水原理也是相似的。

 

　　5) Total dissolved solids (TDS) is high - total dissolved solids refers to the total amount of all solutes in water, and the higher the TDS value, the more dissolved substances are contained in the water. For long-term pools that do not replenish water, TDS over time Accumulation, the pollutants brought by the swimmers and the added drugs gradually accumulate in the pool water, which will lead to too high TDS, affecting the diffusion and adsorption process of the chlorine disinfectant, thereby affecting the sterilization effect of the chlorine disinfectant. It is common in the Dead Sea pool that due to the high salt content, high TDS in the water, limited bactericidal effect of chlorine, leading to problems such as easy algae leeches, the water principle of the swimming pool is similar.
