Kev siv hluav taws xob ultraviolet: Lub zog hluav taws xob hluav taws xob hauv ib cheeb tsam irradiated vertically los ntawm ultraviolet rays, qhia nyob rau hauv mw / cm2, lub zog ultraviolet ntau dua, qhov ze ntawm qhov irradiation, qhov ntau dua qhov kev siv ultraviolet.
Sterilization tus nqi: (tus naj npawb ntawm cov kab mob nyob rau hauv cov dej nyoos spiked - tus naj npawb ntawm cov kab mob tom qab sterilization los ntawm lub sterilizer) / tus naj npawb ntawm cov kab mob nyob rau hauv lub spiked raw dej x 100 feem pua.
Kev siv hluav taws xob ultraviolet: cov khoom siv hluav taws xob siv hluav taws xob thiab lub sijhawm irradiation, nthuav tawm hauv mJ / cm2, uas yog qhov tseem ceeb ntawm kev ua kom tsis muaj zog ntawm ultraviolet sterilizers.Cov koob tshuaj irradiation yog proportional rau sterilization tus nqi.Qhov ntau dua qhov irradiation koob, ntau dua. Lub sterilization npaum li cas.Ib yam li, cov koob tshuaj irradiation yog proportional rau lub sij hawm irradiation.Lub sij hawm irradiation ntev dua, lub siab dua tus nqi sterilization.Lub ultraviolet sterilizers ua los ntawm Agua Topone. muaj koob tshuaj irradiation ntau dua lossis sib npaug li 30mJ / cm2.
Nyob ntawm seb hom kab mob li cas, lub sij hawm thiab qhov ntau npaum li cas ntawm UV sterilization kuj txawv. Cov kab mob sib txawv muaj qhov sib txawv ntawm qhov nqus siab rau UV teeb. Piv txwv li, qhov siab tshaj plaws nqus wavelengths ntawm DNA thiab E.coli yog ob qho tib si 265 nm, thaum lub siab tshaj plaws. absorption wavelengths ntawm Cryptosporidium thiab bacteriophage yog 261 nm thiab 271 nm, ntsig txog.Yog li ntawd, lub sij hawm ua kom tsis muaj menyuam yuav tsum sib txawv.Thaum qhov kev siv hluav taws xob ultraviolet yog 3 × 1 04 μW / cm2, lub sijhawm yuav tsum tau tua cov kab mob. thiab kab mob, pwm spores, thiab kab mob algae yog 0 1-1.0s,1.{{10}}.0s, thiab 5.{{13} }}.0s, ntsig txog.Raws li pab pawg tshawb fawb ntawm Dong Xiaoping, tus kws tshaj lij los ntawm Lub Tsev Haujlwm Saib Xyuas Kabmob Tiv Thaiv thiab Tiv Thaiv ntawm Tuam Tshoj Lub Chaw Tiv Thaiv thiab Tiv Thaiv Kab Mob, UVC irradiation nrog kev siv ntau dua 90 μW / cm3 tuaj yeem tua tau. tus kab mob SARS hauv 30 feeb.

Nyob rau hauv cov xwm txheej ntawm cov koob tshuaj UV txaus, cov kab mob uas tsis muaj zog thiab cov kab mob yuav tsis rov qab los, tab sis thaum cov koob tshuaj tsis txaus, ntau tus kab mob thiab cov kab mob tsis ua haujlwm los ntawm UV hluav taws xob tuaj yeem kho lawv cov qauv puas los ntawm kev pab ntawm lub teeb. tib yam, siab-siv, luv-lub sij hawm los yog tsawg-siv, ntev-lub sij hawm irradiation yuav siv tau mus cuag lub hom phiaj ntawm sterilization.
Tsis tas li ntawd, UV sterilization systems tsis yog tsuas yog kho dej xwb tab sis kuj syrups, kua txiv hmab txiv ntoo thiab cov kev daws teeb meem zoo sib xws.Nyob rau hauv kev xaiv ntawm UV koob, ntxiv rau kev xa mus rau cov ntsiab lus ntawm cov qauv tsim, nws yuav tsum tau txiav txim siab seb puas muaj qee yam kab mob tshwj xeeb hauv cov dej. lub cev, xws li qee cov pwm, uas yuav tsum tau txhaj tshuaj ntau dua los tua.
Cov saum toj no yog cov kev taw qhia ntawm ultraviolet hluav taws xob koob tshuaj thiab sterilization koob tshuaj rau cov kab mob sib txawv.Qhov tseeb, lub ultraviolet hluav taws xob koob tshuaj tsuas yog ib tug ntawm cov ntau yam qhia rau xaiv ib tug UV sterilizer.Xav xaiv ib tug UV sterilizer suits koj xav tau kev pab, koj kuj yuav tsum tau. Txhawm rau kom paub ntau ntxiv, zoo siab txais tos rau npe rau pob zeb diamond UV, peb yuav txuas ntxiv hloov kho UV sterilizers ntxiv rau koj, thiab coj koj mus rau qhov siab tshiab ntawm UV!
