食品、藥品等企業(yè)的產(chǎn)品質(zhì)量如何保證，使用臭氧發(fā)生器對(duì)食品、藥品生產(chǎn)包裝車間、更衣室、庫(kù)房等進(jìn)行消毒是國(guó)際公認(rèn)的最安全可靠的方法，也是QS、GMP、HACCP等潔凈廠房設(shè)計(jì)施工 http://www.jnjkjh.com/ 認(rèn)證管理的一項(xiàng)基本要求。實(shí)際上國(guó)內(nèi)的很多企業(yè)對(duì)臭氧消毒滅菌的知識(shí)了解不多，同時(shí)又受到某些臭氧發(fā)生器廠家或設(shè)計(jì)單位的誤導(dǎo)，因此很多使用者對(duì)臭氧發(fā)生器的選購(gòu)和使用不規(guī)范、不科學(xué)，達(dá)不到預(yù)期的消毒滅菌效果。
Food, medicine and other enterprise product quality assurance, the use of ozone generator for food, pharmaceutical production and packaging workshop, dressing room, warehouse and other disinfection is internationally recognized as the most safe and reliable method, but also QS, HACCP, GMP and other clean plant design and construction certification management of a basic requirement. In fact, many enterprises in China have little knowledge about ozone disinfection and sterilization, but also by some ozone generator manufacturers or design units, so many users of the ozone generator to buy and use non-standard, unscientific, and can not reach the desired disinfection.
一、臭氧消毒的必要性
Necessity of ozone disinfection
國(guó)內(nèi)食品、藥品企業(yè)傳統(tǒng)的消毒方法是使用紫外線燈照射，但紫外線的消毒效果受很多因素的影響，如照射強(qiáng)度、距離等，并且很容易存在消毒死角。而臭氧具有消毒滅菌速度快（3000倍于紫外線，600倍于氯）、消毒無(wú)死角、無(wú)任何殘留物、使用方便等優(yōu)點(diǎn)。所以近年來(lái)國(guó)家商檢、質(zhì)量、衛(wèi)生等監(jiān)管部門已明確要求相關(guān)企業(yè)淘汰紫外線燈，推薦使用臭氧發(fā)生器對(duì)空間和生產(chǎn)用水進(jìn)行殺菌消毒。
Domestic food, pharmaceutical companies, the traditional disinfection method is the use of ultraviolet light irradiation, but the disinfection effect of ultraviolet radiation by a lot of factors, such as irradiation intensity, distance, etc., and very easy to disinfect dead. The ozone has the advantages of fast sterilization, which is fast (3000 times as high as ultraviolet ray, 600 times Yu Lv), no dead angle, no residue, etc.. So in recent years, the State commodity inspection, quality, health and other regulatory authorities have been explicitly required to eliminate the relevant enterprises to eliminate ultraviolet light, recommended the use of ozone generator for space and water disinfection.
二、臭氧消毒的相關(guān)標(biāo)準(zhǔn)
Two, ozone disinfection related standards
參照國(guó)家衛(wèi)生部《消毒技術(shù)規(guī)范》及QS、GMP、HACCP等認(rèn)證的要求，在使用臭氧對(duì)潔凈車間（潔凈度30萬(wàn)級(jí)以下）進(jìn)行消毒時(shí)，車間內(nèi)的臭氧濃度應(yīng)該達(dá)到或超過(guò)10mg/m³的濃度標(biāo)準(zhǔn)；并且在達(dá)到這一標(biāo)準(zhǔn)后，繼續(xù)密閉消毒30分鐘。如果是對(duì)場(chǎng)所內(nèi)的物品消毒，臭氧的濃度應(yīng)適當(dāng)提高。對(duì)于潔凈度較高的車間，如對(duì)10萬(wàn)級(jí)、萬(wàn)級(jí)的車間消毒時(shí)，臭氧濃度則應(yīng)提高到20-30mg/m³。
According to the national Ministry of health "disinfection technical specifications" and the GMP, HACCP, QS certification requirements, in the use of ozone on the clean workshop (cleanliness level 300000), the workshop ozone concentration should reach or exceed 10mg/m³ the concentration of the standard; and in the standard, continue to seal disinfection for 30 minutes. If it is for the items in the place, the concentration of ozone should be improved. For the workshop with a high degree of cleanliness, the ozone concentration should be raised to the level of 20-30mg/m³ in the 100000 - grade and grade - level workshops;.
三、影響臭氧消毒效果的因素和注意事項(xiàng)
Three, the impact of ozone disinfection and the factors that affect the effect of ozone
在實(shí)際應(yīng)用中，影響臭氧消毒效果的因素主要有以下幾方面。
In practical application, the factors that affect the ozone disinfection effect are mainly the following aspects.
1. 臭氧投加量
1 ozone dosage
空間消毒是如果臭氧的投加量達(dá)不到標(biāo)準(zhǔn)數(shù)值，那么空間內(nèi)的臭氧濃度也達(dá)不到要求的標(biāo)準(zhǔn)，消毒效果必然受影響。在計(jì)算臭氧投加量時(shí)，必須考慮臭氧在輸送過(guò)程中的損耗、門窗泄露等綜合因素，同時(shí)，也必須保證所選用的臭氧發(fā)生器能夠達(dá)到設(shè)計(jì)的臭氧產(chǎn)量。
Space disinfection is if the amount of ozone is not up to the standard value, then the ozone concentration in space can not meet the requirements of the standard, disinfection effect is bound to be affected. In calculating the ozone dosage, we must take into account the ozone in the transport process of the loss, windows and doors leakage and other factors, at the same time, also must ensure that the ozone generator used to achieve the design of ozone production.
2. 臭氧的均勻度
2 uniformity of ozone
在消毒空間內(nèi)，必須保證所有角落的臭氧濃度都能夠達(dá)到消毒標(biāo)準(zhǔn)，否則消毒效果還是很差。為此，在設(shè)計(jì)消毒方案時(shí)，必須周密考慮車間結(jié)構(gòu)、臭氧投加方式、臭氧發(fā)生器性能等因素。臭氧發(fā)生器必須具有遠(yuǎn)距離輸送臭氧的能力，空間消毒的話最好選用空氣源的臭氧發(fā)生器，如果車間有新風(fēng)系統(tǒng)，當(dāng)然最好，可以將臭氧發(fā)生器接到出風(fēng)口；如果沒有新風(fēng)系統(tǒng)可以選擇鋪設(shè)管道的方式，但是臭氧的投加量比標(biāo)準(zhǔn)投加要稍微大一些。
In disinfection space, must ensure that all corners of ozone concentrations are able to reach the disinfection standards, otherwise disinfection effect is still very poor. To this end, in the design of disinfection scheme, we must consider the workshop structure, ozone dosing, ozone generator performance and other factors. Ozone generator must have the ability to transport ozone, the best choice of air source ozone generator, if there is a fresh air system, of course, can be the ozone generator outlet; if there is no air system can choose the way of laying pipelines, but the ozone dosage is slightly larger than the standard.
3. 臭氧消毒的時(shí)間
3 ozone disinfection time
雖然臭氧的消毒滅菌作用是在瞬間完成的，但臭氧濃度在空間內(nèi)需要一定時(shí)間的積累，如果消毒時(shí)間不夠，消毒效果也會(huì)受影響。一般要求臭氧發(fā)生器停機(jī)半小時(shí)到一小時(shí)內(nèi)，仍需密閉門窗。
Although the ozone disinfection is done in an instant, but the ozone concentration in space needs a certain amount of time, if the disinfection time is not enough, the disinfection effect will also be affected. Generally require the ozone generator to stop half an hour to an hour, still need to close the doors and windows.
4. 臭氧發(fā)生器的性能
4 performance of ozone generator
如果臭氧發(fā)生器的性能較差，在使用到一定時(shí)間后，臭氧產(chǎn)量會(huì)急劇減少，那么消毒效果將無(wú)從保證。臭氧發(fā)生器的核心部件就是臭氧放電體和專用電源，所以在采購(gòu)時(shí)，要選擇可靠的臭氧發(fā)生器廠家，要考慮臭氧放電體和電源的匹配性，最好是廠家自己研發(fā)生產(chǎn)。
If ozone generator performance is poor, in the use of a certain time, the ozone production will be reduced dramatically, so the disinfection effect will not be guaranteed. The core part of the ozone generator is the ozone discharge body and special power supply, so when the purchase, to choose a reliable ozone generator manufacturers, to consider the ozone discharge and power supply, the best is the manufacturer's own R & D and production.
5. 其他
5 other
空間內(nèi)環(huán)境溫度、濕度、密封程度、空氣潔凈度等，都會(huì)影響臭氧的消毒效果。使用臭氧發(fā)生器的環(huán)境溫度不要超過(guò)40攝氏度，濕度最好在60%-80%之間，空氣經(jīng)過(guò)過(guò)濾凈化的空間。
Space environment temperature, humidity, seal, air cleanliness, etc., will affect the ozone disinfection effect. Use ozone generator of the ambient temperature should not exceed 40 degrees Celsius, humidity is best between 60%-80%, the air through the filtering and purification of space.
