Amagciwane kanye negciwane kukhona emoyeni, emanzini nasenhlabathini, futhi cishe kuyo yonke indawo yokudla, izitshalo nezilwane.Iningi lamabhaktheriya negciwane alilimazi imizimba yabantu.Nokho, ezinye zazo ziyaguquka ukuze kulimaze amasosha omzimba, okusongela impilo yomuntu.
Iyini imisebe ye-Ultraviolet
Uhlobo oluvame kakhulu lwemisebe ye-UV ukukhanya kwelanga, okukhiqiza izinhlobo ezintathu eziyinhloko zemisebe ye-UV, i-UVA (315-400nm), i-UVB (280-315nm), ne-UVC (emifushane kuno-280 nm).Ibhande le-UV-C lemisebe ye-ultraviolet enobude begagasi obuzungeze u-260nm, ekhonjwe njengomsebe osebenza kahle kakhulu wokuvala inzalo, isetshenziselwa ukuvala inzalo yamanzi.
Isimiso Sokusebenza
I-sterilizer ihlanganisa amasu aphelele avela ku-optics, i-microbiology, i-chemistry, i-electronics, mechanics kanye ne-hydromechanics, idale imisebe ye-UV-C ejulile futhi ephumelelayo yokukhipha amanzi agelezayo.Amagciwane namagciwane emanzini abhujiswa umthamo owanele wemisebe ye-UV-C (ubude begagasi obungu-253.7nm).Njengoba i-DNA kanye nokwakheka kwamangqamuzana kucekelwe phansi, ukuvuselelwa kweseli kuyavinjelwa.Ukukhipha amagciwane nokuhlanzwa kwamanzi kufeza ngokuphelele.Ngaphezu kwalokho, i-UV ray enobude obuyi-185nm ikhiqiza ama-radicals e-hydrogen ukuze i-oxidize ama-organic molecule abe yi-CO2 ne-H2O, futhi i-TOC emanzini iyaqedwa.
Izinzuzo zokubulala amagciwane kwe-UV-C kanye nokubulala inzalo
● Ayiguquli ukunambitheka, i-pH, noma ezinye izici zamanzi
● Ayikhiqizi imikhiqizo yokubulala amagciwane eyakhiwe
● Ayikho ingozi yokweqisa futhi ingalawulwa kalula ekushintsheni ukugeleza kwamanzi noma izakhiwo zamanzi
● Isebenza kuzo zonke izinhlobo zezinto ezincane, okuhlanganisa amagciwane, amagciwane, isikhunta, ne-protozoa.
● Yehlisa amakhemikhali adingekayo
● Iphephile futhi inobungani nemvelo
Ubuningi kanye Neyunithi Yemisebe ye-Ultraviolet
I-Irradiance Value Yezisetshenziswa Zethu
Imithamo yesikali
Zonke izinto eziphilayo ezincane zidinga umthamo ohlukile ukuze ungasebenzi.
Nt/Cha = exp.(-keEefft)…………………1
Ngakho-ke ku-Nt /N o = --keEefft…………2
● Nt inombolo yamagciwane ngesikhathi t
● Cha inani lamagciwane ngaphambi kokuchayeka
● k izinga elingaguquki kuye ngohlobo
● I-Eefft i-irradiance esebenzayo ku-W/m2
Umkhiqizo u-Eeft ubizwa ngokuthi umthamo osebenzayo
I-Heff ivezwe ngo-Ws/m2 kanye no-J/m2
Lokhu kulandela ukuthi ku-90% ukubulala i-equation 2 kuba
2.303 = kHeff
Ezinye izinkomba zenani lika-k zinikezwe kuthebula lesi-2, lapho zingabonakala zihluka kusuka kumagciwane angu-0.2 m2/J namabhaktheriya, kuya ku-2.10-3 ngezinhlamvu zesikhunta kanye no-8.10-4 ku-algae.Kusetshenziswa izibalo ezingenhla, umfanekiso 14 okhombisa ukusinda noma ukubulala % uma kuqhathaniswa nethamo, ungakhiqizwa.
