Proper use of environmentally safe and harmless

 product ozone equipment

      Ozone applications in many industries in our country has achieved good results, and gradually for people to understand and accept. However, the use of safe sex and physical damage there is still doubts about who should be the attitude of science to answer these questions.
"Ozone" is due to "protection of the atmosphere" propaganda and well known. Because ozone refrigerator deodorizer, ozone Xiaoduwangui other home appliances market, people have become familiar with the application of ozone.
Ozone has a distinctive smell. Initially it was found that according to the smell of new substances. In 1840, German scientist Shu Bei because (Schonbein) reports submitted to the Academy in Munich announced the discovery of ozone. Spark discharge him under electrolysis experiments with the odor and stench in the air after lightning smell the same, determine the odor is caused by a new substance produced, and this new material named "OZONE" --- ozone, the term according to Greek Ozein (odor) transliteration of the word
Ozone was officially discovered after six decades, scientists from various countries study identified three oxygen atoms of ozone as the structure and physical and chemical parameters, and carried out artificial ozone-generating equipment ----- ozone generator developed ozone application experiments. In 1904, Germany. Pull. Kukes (de la coux) published up to 557 ozone technology and application reference.
Ozone in nature:
Ozone O3 is the oxygen allotrope of O2, the same constituent elements constitute morphological differences, very different nature.
Ozone applications:
1, water treatment
Ozone in the water of bacteria, viruses and other microorganisms kill rate of speed on the complete removal of organic compounds and other pollutants without secondary pollution, so the application of ozone water disinfection is the most important sector, ozone water industry the largest market.
Chlorine disinfection in water plant applications is very common. But ozone on bacteria kill rate is higher, kill faster. Chlorine disinfection of water quality are particularly sensitive to changes in pH, pH value changed from 7.5 to 8.0 chlorine dosage should increase 2.5 times, while the ozone dosage changed little. Currently using ozone instead of chlorine disinfection most important factor, but also the traditional use of chlorine disinfection of the United States, Japan and other countries are in the rapid development of the use of ozone-treated water main reason is that as water pollution by organic chemical industrial products, will produce chlorine disinfection chloroform, methylene bromide, carbon tetrachloride, chlorinated organics (THM), these substances have carcinogenic, and ozone oxidation treatment does not produce secondary pollution compounds.
Sterilization of bottled water purification process using ozone is most common, positive, a rough estimate, mineral water, pure water, clean water more than ten thousand, about 80% of the sterilization process using ozone. Due to technical supervision, and epidemic prevention departments have formed a consensus, there is no ozone equipment for bottled water is difficult to compete in the market. With the bottled water market, and domestic development of a large number of ozone equipment manufacturers. Ozone generator, dosing mixing equipment variety, quality is uneven, and even false fake, so bottled water quality can not be guaranteed. The key lies in the treated water should reach 0.3 ~ 0.5mg / L ozone solubility values, which first requires the amount of ozone dosage should satisfy the conditions of 1m3 of water 2g ozone, and must ensure full contact with water ---- gas and maintain a certain period of time . According to practical experience, ozone concentrations higher than 8mg / L is easy to achieve solubility requirements.
Sewage treatment including urban sewage, industrial effluent and sewage medical treatment, mainly for the purpose of disinfection, removal of pollutants and odor bleaching to meet emission standards. In recent years due to lack of water resources plaque, industry department has developed industrial and domestic wastewater reuse regulations, improve the processing standards.
United States in the early seventies of this century began using ozone treatment of sewage, the main purpose of disinfection and reduce biological oxygen demand (BOD) and chemical oxygen demand (COD), remove nitrite, suspended solids and bleaching, has reach full production application level. Japan in the areas of sewage water after ozone treatment as a non-potable water (ie water) recycling.
Ozone is used for electroplating industrial wastewater effluent containing cyanide oxidation, textile printing and dyeing wastewater decolorization, refining sewage to phenol, alkanes substances. United States, Japan, Germany, France and other countries in recent years have established a large-scale sewage treatment plant, China's oil refining, printing and dyeing industry also has pilot applications.
Ozone disinfection of swimming pool water is widely used, its processing effects and advantages has been recognized, the foreign application is extremely common. Of Guangzhou Tianhe Natatorium, Beijing Asian Games Village Ying Tung Natatorium, adopted ozone disinfection, the water is clear and transparent, completely solve the chlorine disinfection irritate the eyes, skin, and the hair yellow issue.
The U.S. Association recommends ozone treatment cooling tower circulating water cooling technology that can achieve scale, cleaning, sterilization algaecide, corrosion and stability of water quality objectives, the U.S. company has computer-controlled testing ozone ozone cooling water circulation system in operation, many units of conducting experimental studies, lessons learned.
Two chemical oxidation
Ozone as an oxidant and catalyst and refining agent used in chemical, petroleum, paper, textiles and pharmaceuticals, fragrances industry. Strong oxidizing power of ozone is easy to interrupt alkenes, alkynes organic compounds with carbon chain bond, after the partial oxidation to form new compounds.
Carbon fiber new material by ozone surface treatment to improve the quality; plastic film ozone treatment to improve the surface color printing capability; pulp bleaching in Norway has been developed to produce experimental stage.
In the biological, chemical contamination gas purification, ozone plays an important role. Fur, casings and the stench of fish processing plants, rubber, chemical plants polluting gases can be released through the smell of ozone.
Ozone can resolve the mustard gas, sarin and other chemical agents.
Ozone on synthetic pesticides act as a catalyst for certain pesticide residues in and can be oxidized and decomposed.
Three food industry applications
Strong bactericidal ability of ozone pollution and the benefits of it without residual disinfection in the food industry, odor, mildew preservation aspects widely used.
1904 had the use of ozone preservation of milk, meat, cheese and other food proteins reported in 1909 French De Bonie refrigeration plant official use chilled meat surface ozone sterilization, and achieved a significant reduction in the number of microbial effects. In 1928 the British established in Tianjin, "Hop Kee egg plant", which beat egg workshop on the use of ozone disinfection. The late thirties, the United States 80% of the frozen egg libraries are equipped with ozone generators, improve egg storage period. It is particularly worth noting that the U.S. Food and Drug Administration (FDA) in April 1997, has been modified to ozone as "food additive" restrict the use of the provisions do not apply to allow in food processing, storage, use ozone. This is a milestone in the development of ozone technology. The U.S. and many countries food processing technology advances, improve food quality, has a major role.
4 Medical Applications
On the ward, operating room air disinfection ozone in our country is to promote the main direction, and carried out a lot of treatment abroad is the application of research experiments. Germany, Switzerland, Russia, France and Italy, the medical and dental doctors, many years in the use of ozone for treatment, such as oral surgery and dental ornament maintain oral sterile water with ozone, ozone in combination with radiation therapy to treat cancer, drinking ozonated water treatment of women's diseases, injecting ozone gas treatment fistula hemorrhoids, varicose veins.
Ozone is a gas safety
Information on the nature of ozone in the introduction cryogenic condensation often referred to ozone and 20% concentrations of ozone and oxygen gas mixture exists the possibility of explosion. In practice, low concentration ozone, such as the application of high-concentration ozone water generator of the highest concentration of 70mg / L (source of oxygen concentration of 5%), as an air processing applications generator at concentrations of 200mg/m3, than explosive concentrations much lower, and hence the security of our application of ozone gas.
It is noteworthy that using oxygen source is indeed large ozone system should be strictly in accordance with safety standards for the design and operation of oxygen. Currently installed in the supply line as the detection of hydrocarbon detector alarm equipment to prevent oxygen explosion accidents.
The application of ozone in a hundred years history, has not been reported instances of ozone explosion.
2 health standards and health protection
Ozone as a gas fungicide, relying on its oxidation generated against viruses, bacteria and fungi and other microorganisms strong role in the killing. Like with any disinfectant for animals and humans caused by certain physiological responses even damage, but the ozone than the commonly used disinfectants to be much smaller, anti-insurance is also much easier.
National scientific community on the physiological damaging effects of ozone had a long in-depth research, and develop the appropriate health standards in order to ensure the health applications.
Ozone industrial hygiene standards:
International Ozone Association: 0.1, the contact 10 hours
United States: 0.1 exposure 8 hours
Germany, France, Japan: 0.1
China: 0.15
Research experiment is multifaceted, beginning from 1950, including by age groups for ozone exposure in order to determine the physiological responses of. In a large number of experimental data on the basis of many researchers in accordance with K = c (concentration) * t (time) Equation established physiological response of human health protection and the relationship between the ozone concentration graph. This figure clearly shows that people in the physiological response of ozone environment and the extent of damage to the product concentration with time, indicating that higher concentrations do not produce significant short contact time of impact, and with the low concentration but a long time may be affected significantly.

The following diagram stimulation zone range without damage zone, ie leave the ozone environment quickly recovered in the affected zone. Figure Pinching means "feel" for the smell of ozone-specific odor; "stimulus" is a respiratory mucosa reaction was dry mouth, cough, sore throat strong stimuli, such as feeling tired, take a few hours to recover. Literature clearly pointed out that the section above stimulation area (poisoning District) is the estimated value. So far in the world without a case of ozone poisoning incidents.
Because people can feel the sense of smell ozone concentrations below health and safety standards, so that any person working area of ozone in the ozone stimulation obviously feel it will automatically take technical measures to avoid or eliminate leakage fault, and not a "product" accumulation damage.
Ozone as a disinfectant, bactericidal ability, use of low concentration, self-decomposition of oxygen can no residual contamination after contact discomfort disappeared immediately left the scene, etc., is formaldehyde (formalin), peracetic acid, potassium permanganate other common disinfectants can not match. Requires the presence of staff directly disinfection is unreasonable. To ensure the correct application of health from ozone damage.
Ozone is not a panacea, nor is it perfect. Should be based on a scientific attitude and approach to publicity, promotion and application of ozone, ozone increased with the development of China's technological level.
