食品、药品等企业的产品质量如何保证，使用臭氧发生器对食品、药品生产包装车间、更衣室、库房等进行消毒是国际公认的最安全可靠的方法，也是QS、GMP、HACCP等洁净厂房设计施工 http://www.jnjkjh.com/ 认证管理的一项基本要求。实际上国内的很多企业对臭氧消毒灭菌的知识了解不多，同时又受到某些臭氧发生器厂家或设计单位的误导，因此很多使用者对臭氧发生器的选购和使用不规范、不科学，达不到预期的消毒灭菌效果。

 

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

 

国内食品、药品企业传统的消毒方法是使用紫外线灯照射，但紫外线的消毒效果受很多因素的影响，如照射强度、距离等，并且很容易存在消毒死角。而臭氧具有消毒灭菌速度快（3000倍于紫外线，600倍于氯）、消毒无死角、无任何残留物、使用方便等优点。所以近年来国家商检、质量、卫生等监管部门已明确要求相关企业淘汰紫外线灯，推荐使用臭氧发生器对空间和生产用水进行杀菌消毒。

 

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、臭氧消毒的相关标准

 

Two, ozone disinfection related standards

 

参照国家卫生部《消毒技术规范》及QS、GMP、HACCP等认证的要求，在使用臭氧对洁净车间（洁净度30万级以下）进行消毒时，车间内的臭氧浓度应该达到或超过10mg/m³的浓度标准；并且在达到这一标准后，继续密闭消毒30分钟。如果是对场所内的物品消毒，臭氧的浓度应适当提高。对于洁净度较高的车间，如对10万级、万级的车间消毒时，臭氧浓度则应提高到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/m&sup3 in the 100000 - grade and grade - level workshops;.

 

三、影响臭氧消毒效果的因素和注意事项

 

Three, the impact of ozone disinfection and the factors that affect the effect of ozone

 

在实际应用中，影响臭氧消毒效果的因素主要有以下几方面。

 

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

 

空间消毒是如果臭氧的投加量达不到标准数值，那么空间内的臭氧浓度也达不到要求的标准，消毒效果必然受影响。在计算臭氧投加量时，必须考虑臭氧在输送过程中的损耗、门窗泄露等综合因素，同时，也必须保证所选用的臭氧发生器能够达到设计的臭氧产量。

 

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. 臭氧的均匀度

 

2 uniformity of ozone

 

在消毒空间内，必须保证所有角落的臭氧浓度都能够达到消毒标准，否则消毒效果还是很差。为此，在设计消毒方案时，必须周密考虑车间结构、臭氧投加方式、臭氧发生器性能等因素。臭氧发生器必须具有远距离输送臭氧的能力，空间消毒的话最好选用空气源的臭氧发生器，如果车间有新风系统，当然最好，可以将臭氧发生器接到出风口；如果没有新风系统可以选择铺设管道的方式，但是臭氧的投加量比标准投加要稍微大一些。

 

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. 臭氧消毒的时间

 

3 ozone disinfection time

 

虽然臭氧的消毒灭菌作用是在瞬间完成的，但臭氧浓度在空间内需要一定时间的积累，如果消毒时间不够，消毒效果也会受影响。一般要求臭氧发生器停机半小时到一小时内，仍需密闭门窗。

 

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. 臭氧发生器的性能

 

4 performance of ozone generator

 

如果臭氧发生器的性能较差，在使用到一定时间后，臭氧产量会急剧减少，那么消毒效果将无从保证。臭氧发生器的核心部件就是臭氧放电体和专用电源，所以在采购时，要选择可靠的臭氧发生器厂家，要考虑臭氧放电体和电源的匹配性，最好是厂家自己研发生产。

 

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

 

空间内环境温度、湿度、密封程度、空气洁净度等，都会影响臭氧的消毒效果。使用臭氧发生器的环境温度不要超过40摄氏度，湿度最好在60%-80%之间，空气经过过滤净化的空间。

 

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.
