Ultraviolet sterilization is meant the method with ultraviolet ray (energy) radiation killing microorganisms and gemma.Its sterilizer is made as ultraviolet ray can make the nucleic acid-protein sex change, after microbial molecular or its analytic metabolism thing molecule are subjected to ultraviolet radiation, energy is released on the orbital electron of atom inside, and absorbed energy makes atom be in more upper state, and has changed the activity of atom; In ultraviolet spectral range, the nucleic acid of cell presents strong absorption band.The important component that known formation is kept cell life is that high molecular weight nucleic acid is DNA (DNA) and ribonucleic acid (RNA), about wavelength 260nm, has maximum absorption spectrum, the thymidine of DNA becomes thymine dimer and loses activity in the cell after ultraviolet radiation, ultraviolet ray simultaneously can make the oxygen of air produce drop ozone, and reaches common sterilization functions.Because ultraviolet ray can be reflected or absorb with straightline propagation by different surfaces, penetration power is faint, and simple glass can absorb ultraviolet ray, and therefore the article that are loaded in the container can not be used ultraviolet disinfection, and this method is mainly as air sterilization, drinking water sterilization and surface sterilizing.Ultraviolet ray can impel the quick oxidation of grease, so should not use ultraviolet disinfection in the grease.
The wavelength that is used for ultraviolet disinfection is 200-300nm, and the strongest wave band of sterilization functions is at 250-260nm.
Uviol lamp must be to produce the sterilizing viltalight lamp that the irradiation value is up to state standards.The ultraviolet light source description is a lot, adopts low pressure mercury lamp here.Low pressure mercury lamp can be divided into hot-cathode low-pressure mercury lamp and cold cathode low-voltage mercury lamp according to cathode type.The power of these two kinds of lamps is less, is no more than 30W.The germicidal low pressure mercury lamp mainly produces the 253.7nm ultraviolet ray.According to spectral power distribution, the ultraviolet ray of wavelength 254nm accounts for uviol lamp and launches 90% of spectrum gross energy, as considers the uviol lamp gross energy, and the ultraviolet gross energy of wavelength 250nm accounts for 60%, and other account for 2% for visible light, and the heat producing losses accounts for 38%.
Country's disinfection technology standard regulation: the radiation intensity of disinfection by ultraviolet light fluorescent tube should not be lower than 70 μ w/cm
2, in the time of killing multiple virus and bacterium, dose of radiation should not be lower than 100 μ w.s/cm
2The ultraviolet lamp tube radiation intensity is influenced by voltage, temperature, radiation length, angle of radiation etc.Be also noted that the cleaning and the service life of fluorescent tube simultaneously.Experiment shows: the every decline 10V of voltage UV intensity decline 15-20 μ w./cm
2, voltage is below 190V, and uviol lamp can not be worked; Under voltage 220V condition, in the room temperature 0-40 ℃ of scope, ultraviolet radiation intensity rises with increase in temperature, for example: lamp hole temperature drops to 4 when spending by temperature 27 degree, output quantity decline 60%-80% is 190-240V at voltage, when room temperature is 16-35 ℃, ultraviolet radiation intensity and voltage, the linear y=-325.12+2.14X of room temperature
1+ 0.72X
2The relation of ultraviolet radiation intensity and distance is E=97.72/L
1.828The coverage of ultraviolet radiation is 0.7-2.4m, in the uviol lamp two ends vertical line outside, increases uitraviolet intensity with angle and significantly decays, and near ultraviolet outer side center line, be 0.So during disinfection by ultraviolet light, adopt multi-lamp and at right angles offset the sterilization dark space mutually.Along with the increase of radiation intensity, the radiated time required to the microorganisms lethal effect reduces, otherwise increases.
Microbe species: various microorganisms are to ultraviolet tolerance difference.Fungal spore is the strongest to ultraviolet tolerance, and bacterial spore takes second place, and the poorest is breeding build microorganism.General bacterial spore than the strong 2-7 of its brood body tolerance doubly.Between with a kind of different strains, the different cultures of same bacterial classification and also variant between different generation to ultraviolet resistance, and relevant with environmental condition.For example at normal temperatures than the Escherichia coli that suspend in the dry air when the wavelength 250-260nm ultraviolet radiation, the about 50 μ w.min/cm of lethal dose
2, but the resistance of bacterium increases under wet environment, and lethal dose is 100 μ w.min/cm
2The required ultraviolet dosage of destroy microorganisms sees Table fully.
Microbial numbers, suspending carrier and organic substance influence experimental results show that the microbiological contamination amount the more, and required radiation ultraviolet dosage is bigger.Bacterium invests dust and is suspended in the air byer force than the resistance in bacterium liquid aerosol, because ultraviolet penetration power is very poor, air dust can absorb ultraviolet ray and reduce sterilizing rate, contains dirt powder 800-900/cm in air
3The time, bactericidal potency can reduce 20%-30%; The existence of peptone, egg, cow's milk, blood, serum all can strengthen microorganism to ultraviolet resistance.
Temperature Influence, most microorganisms (it is outer to fall Micrococcus) are very sensitive to ultraviolet radiation when low temperature, because with this understanding, the quantity of thymine dimer obviously reduces, the accumulation of thymidine photoproduct will influence the reparation of microorganism, and variations in temperature also influences ultraviolet intensity.Too high or too low for temperaturely all can influence Disinfection Effect, general temperature is advisable with 20-40 ℃.
The influence of humidity: relative humidity is more than 60%-70%, and the killing rate of microorganism sharply descends, and the suitableeest is 40%-60%, surpasses 80% even anti-activation arranged.Relative humidity increases at 56% o'clock by 33%, and bactericidal potency can reduce to original 1/3.Humidity may show three aspects to the influence of sterilizing rate: 1. because the relative humidity height makes particle increase in the air, be easy to catch when sampling, make bactericidal effect be the surface and upward reduce.2. the particle increase weakens the radiation penetration cell, thereby killing effect reduces.3. during relative humidity 60%-70%, in the air bacterium moisture be 30g/100g bacterium rule, this amount claims the critical water yield.The ultraviolet energy transmission can destroy the macromolecular conjugate relation of bacterium, and this effect easily occurs in, in the bacterium of critical moisture content and dehydration, so the ultraviolet sterilization rate is lower under the general super-humid conditions.
Because the ultraviolet radiation energy is low, a little less than the penetration power, only can kill the microorganism that directly is radiated, must make the sterilization position fully be exposed to ultraviolet ray during sterilization, so present ultraviolet sterilization is applied to air sterilization, the sterilization of the direct irradiation part of the sterilization and the surface of solids in the water.
The mounting means of ultraviolet lamp generally has ceiling type, suspension type and wall lamp type.Press the irradiation direction branch of lamp and go up according to formula and the following formula of shining, every cubic metre space mounting uviol lamp should be no less than 1.5W, and radiated time is no less than 30 minutes.
Ultraviolet ray air sterilization effect is relevant with environment temperature, and the 253.7nm ultraviolet ray of room temperature 20 ℃ of times institute's radiation is the strongest, and room temperature is when 10 ℃ or 40 ℃, and the ultraviolet ray reduction 10%-15% of institute's radiation then reduces by 50% in the time of 0 ℃.The temperature of room air and dust influence ultraviolet sterilization effect by influencing ultraviolet aerial penetrance, and during as relative air humidity 75%, it is about 18.7% that its sterilizing rate reduces during than RH25%, and for example dustiness 8.5 * 10 in the air
5During grain/L, reduce 20%-30% during sterilization when dustless, thus when ultraviolet sterilization is used for solid pharmaceutical preparation, strengthen air cleaning, local exhaust and often the ultraviolet laying dust of cleaning be necessary.Dose of radiation is relevant with ultraviolet radiation intensity of being accepted by radiant matter and radiated time: dose of radiation=intensity X time.Uitraviolet intensity with by the distance dependent of radiant matter to uviol lamp, when radiation length＜1/2 fluorescent tube length, the intensity radiation length is inversely proportional to; During radiation length＞1/2 fluorescent tube length, square being inversely proportional to of intensity and distance.
Ultraviolet ray is very high to the transmitance of water, and the ultraviolet sterilization effect is better, so can be used for drinking water disinfection, ultraviolet ray transmissivity is relevant with the solute concentration in the solution, and solute concentration increases, and transmitance reduces, during solution sterilization, dose of radiation should corresponding increase (seeing the following form).
Ultraviolet ray is to the transmitance of liquid
Surface of solids sterilization: during sterilization, light source is good apart from pollution face less than 1m, needs 30 minutes approximately.Sterilization effect is best in the ultraviolet disinfection cabinet! The inwall of sterilization cabinet should adopt the higher aluminium sheet of reflectivity after processing, to strengthen the irregular reference effect.As cabinet domestic demand layering glove, dividing plate need be with netted, and uviol lamp should top and lower curtate in cabinet be placed, and is more as the number of plies, then all need place uviol lamp for every layer.
