Lub teeb tshuaj tua kab mob ua haujlwm feem ntau yog los ntawm ultraviolet (UV) hluav taws xob, tshwj xeeb tshaj yog luv luv -wave ultraviolet rays hauv UVC band (200-280nm), uas tuaj yeem rhuav tshem DNA / RNA qauv ntawm cov kab mob, ua rau lawv poob lawv lub peev xwm los tsim dua lossis tuag ncaj qha. Cov hauv qab no yog ib qho kev ntsuam xyuas ntxaws:
1. Cov ntsiab lus tseem ceeb: ultraviolet sterilization (UVGI)
Lub hom phiaj: Cov khoom siv caj ces (DNA lossis RNA) ntawm cov kab mob (cov kab mob, kab mob, fungi, spores, thiab lwm yam).
Kev puas tsuaj mechanism:
UVC ultraviolet rays (lub zog sterilization band:25 3,7nm) yog absorbed los ntawm nucleic acid ntawm microorganisms.
Nws ua rau tsim cov pyrimidine dimers (xws li thymine dimers) nyob rau hauv nucleic acid molecules, ua rau nws tsis yooj yim sua rau DNA / RNA replicate thiab transcript ib txwm.
Cov kab mob tuag los yog inactivated vim poob ntawm lawv lub peev xwm los tsim dua tshiab.
2. Hom tshuaj tua kab mob teeb
(1) Tsawg- siab mercury teeb (ib txwm UV teeb)
Txoj Cai: Tsim khoom253.7nm UVCthiab ib qho me me ntawm 185nm ultraviolet rays (uas tuaj yeem tsim ozone) los ntawm mercury vapor tawm.
Nta: High sterilization efficiency, tab sis muaj mercury, yog li nws yuav tsum tau ceev faj.
(2) UV LED tshuaj tua kab mob teeb
Lub hauv paus ntsiab lus: Semiconductor lub teeb emission, ncaj qha tsim UVC band (xws li 265nm).
Nta: Mercury-dawb, lub zog- txuag, tab sis tsis muaj zog, yuav tsum tau siv sij hawm ntev dua irradiation.
(3) Ozone disinfection teeb
Lub hauv paus ntsiab lus: 185nm ultraviolet rays decompose oxygen (O₂) rau hauv ozone (O₃), thiab ozone muaj zog oxidative zog uas rhuav tshem cov kab mob microbial.
Nta: Yuav tsum muaj qhov chaw kaw, thiab qhov cua yuav tsum tau ua tom qab tshuaj tua kab mob (ozone muaj teeb meem rau tib neeg lub cev).
3. Cov yam ntxwv cuam tshuam rau cov tshuaj tua kab mob
Irradiation siv sijhawm thiab sijhawm:
Nws yuav tsum tau ua kom tau raws li qhov xav tau ntawm koob tshuaj=siv (μW / cm²) × lub sijhawm (s). Piv txwv li, nws yuav siv li 10-20mJ / cm² los tua tus kabmob tshiab.
nrug: Qhov kev siv ntawm ultraviolet rays decays nrog lub square ntawm qhov deb (qhov ze rau lub teeb, qhov zoo dua cov nyhuv).
Kev tiv thaiv ib puag ncig: Plua plav, kua lossis khoom ntxoov ntxoo yuav txo cov nyhuv.
Cov kab mob microbial: Cov kab mob sib txawv muaj qhov sib txawv rau cov kab hluav taws xob UV (xws li cov kab mob spores yog ib qho nyuaj rau tua dua li cov kab mob zoo tib yam).
4. Kev ceev faj txog kev nyab xeeb
Tsis txhob cuam tshuam ncaj qha: UVC tuaj yeem ua rau daim tawv nqaij (liab thiab o) thiab qhov muag (keratitis), yog li tib neeg, tsiaj txhu, thiab nroj tsuag yuav tsum tau tawm thaum siv nws.
Kev pheej hmoo ozone: Tom qab ozone tshuaj tua kab mob, qhov cua yuav tsum tau ntau tshaj 30 feeb ua ntej nkag mus.
Lub neej teeb: Lub neej ntawm lub teeb mercury yog li 8,000 teev, thiab UV LED yog li 10,000 teev, thiab yuav tsum tau hloov tsis tu ncua.
5. Cov xwm txheej ntawm daim ntawv thov
Cov chaw kho mob: Cua thiab tshuaj tua kab mob saum npoo hauv chav ua haujlwm thiab pawg ntseeg.
Kev siv hauv tsev: tua kab mob hauv chav dej, chav ua noj, thiab khoom siv rau niam thiab menyuam.
Kev kho dej: UV dej purifiers tua cov kab mob hauv dej.
Cua purification: Inactivate cov kab mob nyob rau hauv cov huab cua nrog ib tug ncig system.
6. Kev txwv
Tsis muaj kev cuam tshuam ntev: Tsuas yog siv tau rau thaj chaw irradiated, thiab ib puag ncig yuav kis kab mob dua tom qab tshuaj tua kab mob.
Kev nkag mus tsis muaj zog: Tsis tuaj yeem nkag mus rau iav, yas, lossis cov av tob.
Los ntawm kev siv lub teeb pom kev zoo ntawm cov tshuaj tua kab mob ultraviolet, feem ntau cov kab mob pathogenic tuaj yeem ua haujlwm tsis zoo, tab sis cov cai tswj kev nyab xeeb yuav tsum tau ua raws li nruj me ntsis.
