Indwara ya bagiteri na virusi bibaho mu kirere, mu mazi no mu butaka, ndetse no hejuru y’ibiribwa, ibimera n’inyamaswa.Benshi muri bagiteri na virusi ntibibabaza umubiri wabantu.Nyamara, bamwe muribo bahindura kwangiza umubiri wumubiri, bikangiza ubuzima bwabantu.
Imirasire ya Ultraviolet ni iki
Uburyo bukunze kugaragara kumirasire ya UV ni urumuri rwizuba, rutanga ubwoko butatu bwingenzi bwimirasire ya UV, UVA (315-400nm), UVB (280-315nm), na UVC (bigufi kuri 280 nm).Itsinda UV-C rya ultraviolet ray ifite uburebure bwa metero 260nm, byagaragaye ko ari imirasire ikora neza muguhagarika, ikoreshwa muguhagarika amazi.
Ihame ry'akazi
Sterilizer ihuza tekinike yuzuye kuva optique, microbiologiya, chimie, electronics, ubukanishi na hydromechanics, ikora imirasire ikomeye kandi ikora neza ya UV-C kugirango imirase y'amazi atemba.Bagiteri na virusi biri mumazi byangizwa nubunini buhagije bwa UV-C (uburebure bwumuraba 253.7nm).Nkuko ADN n'imiterere y'utugingo byangiritse, kuvugurura ingirabuzimafatizo birabujijwe.Kurandura amazi no kweza birangira rwose.Byongeye kandi, imirasire ya UV ifite uburebure bwa 185nm itanga hydrogène radicals kugirango ihindure molekile kama kuri CO2 na H2O, hanyuma TOC mumazi ikavaho.
Ibyiza bya UV-C Gutera no Kurwanya
● Ntabwo ihindura uburyohe, pH, cyangwa ibindi bintu byamazi
● Ntabwo itanga imiti yica udukoko twangiza ubuzima
● Nta ngaruka zo gukabya kandi birashobora gutegekwa byoroshye guhindura amazi cyangwa imiterere y'amazi
● Kurwanya ubwoko bwose bwa mikorobe, harimo bagiteri, virusi, ibihumyo, na protozoa
Kugabanya imiti ikenewe
Umutekano kandi utangiza ibidukikije
Umubare nigice cyumuriro wa Ultraviolet
Indangagaciro za Irradiance yibikoresho byacu
Imirasire
Ibinyabuzima byose bya mikorobe bisaba igipimo gitandukanye kugirango kidakora.
Nt / Oya = exp. (- kEefft) ……………… 1
Kubwibyo muri Nt / N o = --kEefft ………… 2
● Nt ni umubare wa mikorobe mugihe t
● Oya ni umubare wa mikorobe mbere yo kugaragara
● k ni igipimo gihoraho bitewe nubwoko
Efft ni irrasiyo nziza muri W / m2
Igicuruzwa Eefft cyitwa igipimo cyiza
Heff igaragarira muri Ws / m2 na J / m2
Bikurikiraho ko kuri 90% bica ikigereranyo cya 2 kiba
2.303 = kHeff
Ibimenyetso bimwe byerekana agaciro byatanzwe mumeza 2, aho bishobora kugaragara ko bitandukanye na virusi na bagiteri 0.2 m2 / J, kugeza kuri 2.10-3 kuri spore yibumba na 8.10-4 kuri algae.Ukoresheje ibigereranyo hejuru, ishusho 14 yerekana abarokotse cyangwa kwica% na dose, birashobora kubyara.
