中压紫外线的与低压紫外线杀菌器的区别

The difference between medium pressure ultraviolet sterilizers and low pressure ultraviolet sterilizers

     紫外线消毒技术中有中压和低压之分。传统的低压紫外线技术是单波长的，仅仅是破坏细菌的DNA结构，这样微生物很容易在可见光的照射下重新复活（在可见光的照射下重新复活称为光复活）。
中压紫外线杀菌技术完全不同于传统低压紫外线杀菌技术，中压紫外线灯能够产生更宽的紫外光谱，因而能够作用于整个微生物，它不仅仅是对微生物的DNA结构产生破坏，还能使微生物破碎。正是因为这种紫外线技术能有效地避免微生物中DNA的光复活和暗修复的发生，所以能够对微生物产生永久性的灭活作用，没有复活反应，没有菌群反弹现象。

There are two types of ultraviolet disinfection technologies: medium pressure and low pressure. Traditional low-pressure 

ultraviolet technology is single wavelength and only destroys the DNA structure of bacteria, making it easy for 

microorganisms to reactivate under visible light irradiation (known as light reactivation).

The medium pressure ultraviolet sterilization technology is completely different from traditional low pressure ultraviolet 

sterilization technology. The medium pressure ultraviolet lamp can generate a wider ultraviolet spectrum, which can act on the entire microorganism. It not only damages the DNA structure of microorganisms, but also causes them to break. 

It is precisely because this ultraviolet technology can effectively avoid the occurrence of DNA photoreactivation and dark 

repair in microorganisms that it can have a permanent inactivation effect on microorganisms, without any resurrection 

reaction or bacterial rebound phenomenon.

中压紫外线消毒的特性

Characteristics of medium pressure ultraviolet disinfection

Compared to traditional chlorine disinfection, medium pressure ultraviolet radiation has many incomparable 

advantages:

1) Strong bactericidal properties. High sterilization efficiency, fast sterilization speed, and killing effect on common 

bacteria and viruses

It usually takes a few seconds to complete. While causing damage to the DNA structure of microorganisms, they 

are also broken down into small fragments. It is precisely because of this medium pressure ultraviolet sterilization 

property that the occurrence of DNA photoreactivation and dark repair in microorganisms can be effectively avoided. 

Therefore, it can have a permanent inactivation effect on microorganisms without any resurrection reaction or bacterial 

rebound phenomenon.

2) The broad-spectrum sterilization is high. It can efficiently kill all bacteria and viruses, and can permanently inactivate them

Chlorine sensitive microbial tissues, such as Legionella pneumophila, Escherichia coli, Pseudomonas, Cryptosporidium, Amoeba

And bacteria, etc,

3) No toxic or harmful by-products will be produced during the disinfection process, and the composition and properties 

of the disinfected water will not be altered

Quality, no secondary pollution to water bodies and surrounding environment; Reduce the amount of chlorine added, 

reduce residual chlorine, and improve pool water quality

The decrease in chlorine content reduces disinfection by-products, making the swimming pool environment healthier.

4) Medium pressure ultraviolet radiation has the ability to degrade chlorine compounds, including dichloramine, trichloramine, etc,

This effectively eliminates the production of carcinogenic trihalomethanes (THMs) and the impact of chlorinated chlorine on the human body.

While reducing the pungent odor in the swimming pool, it effectively improves the environment for swimmers to play and exercise, and greatly

Improved the working environment for pool staff.

5) Medium pressure ultraviolet disinfection technology has the advantages of small footprint, safe operation, reliability, simple maintenance, and low cost.

It can be seen that medium pressure ultraviolet disinfection has the advantages of high efficiency sterilization, broad-spectrum sterilization, 

no pollution, and safe operation

Due to its advantages of being reliable and not forming toxic by-products, its engineering applications are also increasing.
