Mabakiteriya ndi kachilombo kamakhala mumlengalenga, m'madzi ndi m'nthaka, komanso pafupifupi padziko lonse la chakudya, zomera ndi nyama.Mabakiteriya ambiri ndi ma virus samawononga matupi a anthu.Komabe, ena a iwo amasintha n’kuwononga chitetezo cha m’thupi, n’kuika pangozi thanzi la munthu.
Kodi Ultraviolet Radiation ndi chiyani
Mtundu wofala kwambiri wa cheza cha UV ndi kuwala kwa dzuwa, komwe kumatulutsa mitundu itatu ikuluikulu ya cheza ya UV, UVA (315-400nm), UVB (280-315nm), ndi UVC (yaufupi kuposa 280 nm).Gulu la UV-C la ultraviolet ray lomwe lili ndi kutalika kozungulira 260nm, lomwe ladziwika kuti ndilothandiza kwambiri pakutseketsa, limagwiritsidwa ntchito poletsa madzi.
Mfundo Yogwirira Ntchito
The sterilizer imaphatikiza njira zambiri kuchokera ku optics, microbiology, chemistry, electronics, mechanics ndi hydromechanics, kupanga kuwala kwakukulu komanso kothandiza kwa UV-C kuyatsa madzi oyenda.Mabakiteriya ndi ma virus omwe ali m'madzi amawonongeka ndi kuchuluka kwa UV-C ray (wavelength 253.7nm).Pamene DNA ndi mapangidwe a maselo awonongedwa, kusinthika kwa selo kumaletsedwa.Kupha tizilombo toyambitsa matenda m'madzi ndi kuyeretsa kumakwaniritsa kotheratu.Kuphatikiza apo, kuwala kwa UV komwe kumakhala ndi kutalika kwa 185nm kumapanga ma hydrogen radicals kuti oxidize mamolekyu achilengedwe kukhala CO2 ndi H2O, ndipo TOC m'madzi imachotsedwa.
Ubwino wa UV-C Disinfection ndi Sterilization
● Sasintha kukoma, pH, kapena mikhalidwe ina ya madzi
● Sichimapanga mankhwala ophera tizilombo toyambitsa matenda okhudza thanzi lawo
● Palibe chiwopsezo chochulukirachulukira ndipo chingathe kuwongolera mosavuta kusintha kayendedwe ka madzi kapena mawonekedwe amadzi
● Amalimbana ndi mitundu yonse ya tizilombo tating'onoting'ono, kuphatikizapo mabakiteriya, mavairasi, mafangasi, ndi protozoa
● Amachepetsa mankhwala ofunikira
● Otetezeka komanso osasamalira chilengedwe
Kuchuluka ndi Chigawo cha Ultraviolet Radiation
Mtengo wa Irradiance wa Zida Zathu
Mlingo wa radiation
Tizilombo tating'onoting'ono tonse timafunika mulingo wosiyana kuti usamagwire ntchito.
Nt/No = exp.(-keEeft)……………………1
Chifukwa chake mu Nt /N o = --keEefft…………2
● Nt ndi chiwerengero cha majeremusi pa nthawi t
● Ayi ndi chiwerengero cha majeremusi asanalowe m'thupi
● k ndi mlingo wokhazikika malinga ndi mitundu
● Eeft ndiye kuwala kothandiza mu W/m2
The mankhwala Eeft amatchedwa mphamvu mlingo
Heff imawonetsedwa mu Ws/m2 ndi J/m2
Izi zikutsatira kuti 90% kupha equation 2 kumakhala
2.303 = kHeff
Zizindikiro zina za mtengo wa k zimaperekedwa mu tebulo 2, pomwe zimatha kuwonedwa kuti zimasiyana kuchokera ku 0.2 m2 / J mavairasi ndi mabakiteriya, mpaka 2.10-3 kwa spores za nkhungu ndi 8.10-4 kwa algae.Pogwiritsa ntchito ma equation omwe ali pamwambapa, chithunzi 14 chosonyeza kupulumuka kapena kupha % motsutsana ndi mlingo, chikhoza kupangidwa.
