1. Inkcazo yeukubulala iintsholongwane kunye nokuvalwa
Ukubulala iintsholongwane: Kukuphelisa iintsholongwane, iintsholongwane, kunye neentsholongwane eziyingozi kumzimba womntu.
Ukuvalwa: Bulala zonke iintsholongwane.Nokuba ii-microorganisms ziyingozi okanye ziluncedo kumzimba womntu.
2. Iindlela zokubulala iintsholongwane kunye nokuvala inzala
(1) Indlela yeziyobisi: Ukubulala iintsholongwane kunye nokuvala inzala kwenziwa ngokusula, ukutshiza kunye nokufunxa ngamachiza angenazintsholongwane.La machiza anomhlwa ukuya kuthi ga kwinqanaba elithile, ngoko ke umphezulu oza kuvalwa iintsholongwane kufuneka ube nokunganyangeki kakuhle komhlwa.
amayeza angenazintsholongwane:
a.Ukufutha ngegesi ye-ethylene oxide.25°C, 30% ukufuma okunxulumene, 8 ~16 iiyure.Kukho iqondo elithile letyhefu.
b.Peroxyacetic acid.Uxinaniso 2% yokutshiza.25°C, imizuzu engama-20.Iyadleka.
c.Acrylic acid gas fumigation.25°C, ukufuma okunxulumene nama-80%.Umthamo yi-7g/m3.Kukho iqondo elithile letyhefu.
d.Ukufunxa igesi ye-formaldehyde.25°C, ukufuma okunxulumene nama-80%.Umthamo yi-35ml/m3.Kukho iqondo elithile letyhefu.
e.I-Formalin gas fumigation.25°C, ukufuma okunxulumene ne-10%.Imizuzu eli-10.Iyacaphukisa.
(2) I-Ultraviolet irradiation: I-Ultraviolet ngokubanzi inobude obuyi-1360 ~ 3900, kunye ne-ultraviolet ene-wavelength ye-2537 inobona buchule bunamandla bokuvala inzala.Amandla okubulala iintsholongwane kwisibane se-UV aya kuncipha ngokunyuka kwexesha.Ngokubanzi, amandla aphumayo eeyure ezili-100 zokulayita ngamandla emveliso alinganisiweyo, kwaye ixesha lokucima xa isibane se-UV silayitelwa ukuya kuma-70% ombane olinganisiweyo uchazwa njengobomi obuqhelekileyo besibane se-UV.Ukuba isibane se-UV singaphezulu kobomi obuqhelekileyo kodwa umphumo olindelekileyo wokuvala inzala awunakufezekiswa, isibane se-UV kufuneka sitshintshwe.
Isiphumo sokuvala inzalaIsibane se-UViphinde yahluke ngeentlobo ezahlukeneyo, kwaye idosi ye-irradiation yokubulala isikhunta ilingana namaxesha angama-40-50 idosi ye-irradiation yokubulala i-bacilli.Isiphumo sokuvala isibane sesibane se-UV sikwanxulumene nokufuma komoya.Ukufuma okunxulumene ne-60% lixabiso loyilo.Xa ukufuma okunxulumeneyo kudlula i-60%, ukutyhileka kufuneka kwandiswe.
I-ultraviolet irradiation yesibane kufuneka iqhutywe kwisimo esingenamntu ngenxa yokuba kukho umonakalo othile kumzimba womntu.Isibane se-ultraviolet sinomphumo ongcono wokucoca kunye ne-irradiating phezu komhlaba, kodwa unempembelelo encinci kumoya ohambayo.
3Kuthatha iiyure ezi-2 ukufezekisa injongo yokuvala inzala;xa ubushushu buyi-121℃, ixesha lokuvala inzala yimizuzu eyi-15-20 kuphela.
(4) Kukho ezinye iindlela zokuvala inzala njengelysozyme, nanometer, neradiation.Kodwa eyona ndlela isetyenziswa kakhulu yindlela yokucoca yokuvala inzala.Iisihluzoihluza iintsholongwane kunye ne-microorganisms ezincanyathiselwe eluthulini ngelixa zihluza amasuntswana othuli.
