Cov kab mob thiab kab mob muaj nyob hauv huab cua, dej thiab av, thiab yuav luag txhua qhov chaw ntawm zaub mov, nroj tsuag thiab tsiaj txhu.Feem ntau ntawm cov kab mob thiab kab mob tsis ua mob rau tib neeg lub cev.Txawm li cas los xij, qee qhov ntawm lawv hloov mus ua rau lub cev tsis muaj zog, ua rau tib neeg txoj kev noj qab haus huv.
Dab tsi yog Ultraviolet Radiation
Feem ntau ntawm UV hluav taws xob yog hnub ci, uas ua rau peb lub ntsiab ntawm UV rays, UVA (315-400nm), UVB (280-315nm), thiab UVC (luv dua 280 nm).UV-C band ntawm ultraviolet rays nrog wavelength nyob ib ncig ntawm 260nm, uas tau raug txheeb xyuas tias yog cov kab hluav taws xob zoo tshaj plaws rau kev ua kom tsis muaj menyuam, yog siv rau kev ua kom tsis muaj dej.
Txoj Cai Ua Haujlwm
Cov sterilizer integrates cov txheej txheem los ntawm optics, microbiology, chemistry, electronics, mechanics thiab hydromechanics, tsim high intensive thiab zoo UV-C rays rau irradiate cov dej ntws.Cov kab mob thiab cov kab mob hauv cov dej raug rhuav tshem los ntawm qhov ntim txaus ntawm UV-C rays (wavelength 253.7nm).Raws li DNA thiab cov qauv ntawm cov hlwb tau raug rhuav tshem, lub cell regeneration yog inhibited.Cov dej tua kab mob thiab purification ua tiav tiav.Ntxiv mus, UV hluav taws xob nrog lub wavelength ntawm 185nm tsim hydrogen radicals los oxidize cov organic molecules rau CO2 thiab H2O, thiab TOC hauv dej raug tshem tawm.
Qhov zoo ntawm UV-C Disinfection thiab Sterilization
● Tsis hloov saj, pH, lossis lwm yam khoom ntawm dej
● Tsis tsim tshuaj tua kab mob los ntawm kev noj qab haus huv uas tsim los
● Tsis muaj kev pheej hmoo ntawm overdoing thiab tuaj yeem tswj tau yooj yim rau kev hloov dej ntws los yog cov khoom siv dej
● Siv tau rau txhua hom kab mob, nrog rau cov kab mob, kab mob, fungi, thiab protozoa
● Txo cov tshuaj uas xav tau
● Kev nyab xeeb thiab ib puag ncig-phooj ywg
Ntau thiab Chav Tsev ntawm Ultraviolet Radiation
Irradiance Tus nqi ntawm peb cov cuab yeej
Radiation Dosage
Tag nrho cov kab mob microorganisms yuav tsum tau txhaj tshuaj sib txawv kom tsis txhob ua haujlwm.
Nt /No = exp.(-kEefft)…………………1
Li no hauv Nt /N o = --kEefft…………2
● Nt yog tus naj npawb ntawm cov kab mob thaum lub sij hawm t
● Tsis yog tus naj npawb ntawm cov kab mob ua ntej raug
● k yog tus nqi tas mus li nyob ntawm hom
● Eefft yog cov irradiance zoo hauv W/m2
Cov khoom Eefft hu ua cov koob tshuaj zoo
Heff qhia hauv Ws/m2 thiab J/m2
Nws ua raws li ntawd rau 90% tua kab zauv 2 ua
2.303 TZS = 0
Qee qhov ntsuas tus nqi k tau muab rau hauv cov lus 2, qhov uas lawv tuaj yeem pom txawv ntawm 0.2 m2 / J kab mob thiab kab mob, mus rau 2.10-3 rau pwm spores thiab 8.10-4 rau algae.Siv qhov sib npaug saum toj no, daim duab 14 qhia txog kev muaj sia nyob lossis tua % piv rau koob tshuaj, tuaj yeem tsim tawm.
