勿燥!泳池水中細菌超標與否可用這些儀器檢測,文章是哈維森應大家需求,刻意查閱了相關(guān)文稿也咨詢(xún)了一些資深技工后進(jìn)行了簡(jiǎn)單整理,粗略見(jiàn)解,僅供參考。因為現在無(wú)論是生產(chǎn)商亦或是客戶(hù)對產(chǎn)品要求都比較高,要了解的很細致入微。確實(shí)情況也是這樣,知根知底才能運用自如。
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.
泳池水中有多少細菌或者細菌是否超標?用肉眼是無(wú)法看見(jiàn)及確定的。同樣我們呼吸的空氣中也有各種各樣的細菌存在我們也是無(wú)法通過(guò)肉眼看見(jiàn)。對于細小的物質(zhì),只有在顯微鏡下才能看到或用專(zhuān)門(mén)的儀器檢測才能下結論,如水質(zhì)監測儀、cod測定儀、pH測試儀等等。
How many bacteria or bacteria in the pool water are exceeded? It is invisible and identifiable with the naked eye. Similarly, there are various kinds of bacteria in the air we breathe. We can't see them through the naked eye. For small substances, only under the microscope can be seen or tested with special instruments, such as water quality monitors, cod analyzers, pH testers, etc.
游泳池場(chǎng)所衛生標準中規格泳池水中細菌總數應小于等于1000個(gè)/mL,也就是說(shuō)超過(guò)這個(gè)范圍將會(huì )對泳客帶來(lái)不適皮膚過(guò)敏、瘙癢、起疹子、尿路感染等等問(wèn)題。由于市面上檢測泳池水中細菌的儀器昂貴。大多數泳池都不是直接檢測細菌總數的,而是通過(guò)每天檢測泳池水中的余氯來(lái)保證游泳池水具有消毒能力,抑制水中的細菌,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.
細菌總數是衡量池水循環(huán)凈化處理系統運行質(zhì)量的一個(gè)重要指標,也是主要了解池水消毒是否*的有效方法。通過(guò)水傳播的病源微生物很多,不可直接測定各種病源微生物。為此通過(guò)細菌總數和大腸桿菌數這兩個(gè)指標,可以間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時(shí)水中的細菌總數和大腸菌群是能夠控制在標準范圍內的,那么引起細菌超標主要分兩部分來(lái)說(shuō)。
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. 余氯值過(guò)低。導致細菌繁殖。余氯過(guò)低直接加藥用用藥量即能提升余氯值,不過(guò)也有出現過(guò)這類(lèi)現象,投加藥劑很多氯消毒劑后,檢測水中的余氯還是沒(méi)有提高,不要著(zhù)急看后面處理方法。
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. 余氯值過(guò)高。但水中細菌還是超標。余氯高,為什么細菌還是超標?首先要知道是什么原因導致余氯高的情況下細菌依然超標。
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——影響次氯酸和次氯酸根的含量,從而影響氯消毒劑的擴散吸附過(guò)程,殺菌效果減弱。
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)結合性余氯含量過(guò)高——水中的有機物、尿素等產(chǎn)生氯胺,會(huì )使氯的消毒殺菌能下降,而氯胺就是我們所說(shuō)的結合性余氯/化合性余氯結合性余氯能夠擴散吸附到細菌表面,但是殺菌力弱。
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——只要使用三氯異氰尿酸或二氯異氰尿酸為主要成分的含氯消毒劑,在水解后都含有氰尿酸,而氰尿酸作為穩定劑,它能控制次氯酸一次只生成一定的數量,使藥劑中的氯逐漸釋放出來(lái),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.
不過(guò)在池水中會(huì )不斷累積,氰尿酸過(guò)低,氯消毒劑會(huì )很快被揮發(fā)消耗掉,但氰尿酸過(guò)高,就會(huì )失去對氯的緩釋作用,讓游離性余氯與氰尿酸之間失去平衡,導致游離性余氯的消毒和氧化能力下降,造成菌群、藻類(lèi)滋生、水發(fā)白渾濁。甚至導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)溫度低——溫度會(huì )影響氯消毒劑的擴散速度,從而影響氯消毒劑的殺菌性能。溫度越低,消毒劑的擴散速度越慢殺菌效果越差。一般對室內恒溫泳池、洗浴場(chǎng)所等影響較大。
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)總溶解性固體(TDS)高——總溶解固體是指水中全部溶質(zhì)的總量,而TDS值越高,表示水中含有的溶解物越多,對于長(cháng)期不補水的池子,TDS隨著(zhù)時(shí)間累積,泳客帶入的污染物以及投加的藥劑逐漸在池水中累積,會(huì )導致TDS過(guò)高,影響氯消毒劑的擴散吸附過(guò)程,從而影響氯消毒劑的殺菌效果。常見(jiàn)的是在死海池中,由于鹽分高,水中的TDS高,氯的殺菌效果受限,導致容易長(cháng)藻水渾等問(wèn)題,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.
