Kev siv tshuaj tua kab mob rau cov dej haus yog lub hom phiaj tseem ceeb - tshem tawm feem ntau ntawm cov kab mob phem, nrog rau cov kab mob, kab mob, thiab protozoa, txhawm rau tiv thaiv kev kis kab mob hauv dej.Thaum cov tshuaj tua kab mob tsis tshem tawm tag nrho cov kab mob, nws ua kom ntseeg tau tias qhov kev pheej hmoo ntawm cov kab mob hauv dej raug txo kom tsawg mus rau qib uas pom zoo raws li cov qauv microbiological.Sterilization, ntawm qhov tod tes, hais txog kev tshem tawm tag nrho cov kab mob uas muaj nyob hauv dej, thaum cov tshuaj tua kab mob tsom rau ib feem ntawm cov kab mob pathogenic, txo cov kev pheej hmoo cuam tshuam nrog cov kab mob hauv dej.

Evolution of Disinfection Techniques
Ua ntej nruab nrab xyoo pua 19th, thaum cov kab mob pathogenic tau tsim, cov ntxhiab tsw tau suav tias yog qhov nruab nrab rau kev sib kis kab mob, cuam tshuam rau kev txhim kho cov dej thiab dej phwj hauv kev coj noj coj ua.

Tshuaj tua kab mob rau haus dej
Tshuaj tua kab mob lub cev
Kev siv lub cev xws li cua sov, pom, ultraviolet (UV) hluav taws xob, thiab irradiation yog ua haujlwm.Cov dej kub npau npau yog ib qho, siv tau rau kev kho me me, thaum pom txoj hauv kev zoo li xuab zeb, asbestos, lossis fiber ntau vinegar lim tshem cov kab mob tsis tua lawv.UV hluav taws xob, tshwj xeeb tshaj yog nyob rau hauv thaj tsam 240-280nm, nthuav tawm cov khoom siv tshuaj tua kab mob, tsim rau cov dej me me, siv cov tshuaj tua kab mob ncaj qha lossis lub tes tsho-hom UV.

UV Disinfection
UV hluav taws xob nruab nrab ntawm 200-280nm zoo tua cov kab mob yam tsis tau siv tshuaj, ua kom muaj txiaj ntsig zoo rau kev tswj cov kab mob ua rau cov kab mob.

Tshuaj tua kab mob
Cov tshuaj tua kab mob muaj xws li chlorination, chloramines, chlorine dioxide, thiab ozone.

Cov tshuaj chlorine
Chlorination, ib txoj kev siv dav dav, qhia tau tias muaj zog, ruaj khov, thiab muaj txiaj ntsig zoo ntawm cov tshuaj tua kab mob, siv tau zoo hauv kev kho dej.Chloramines, ib tug derivative ntawm chlorine thiab ammonia, khaws cov dej saj thiab xim nrog qis oxidative muaj peev xwm tab sis yuav tsum tau complex txheej txheem thiab ntau dua concentrations.

Chlorine Dioxide
Raws li cov tshuaj tua kab mob thib plaub, chlorine dioxide tshaj cov tshuaj chlorine hauv ntau yam, ua kom pom cov tshuaj tua kab mob zoo dua, tshem tawm saj, thiab txo qis cov khoom noj carcinogenic.Nws tsis tshua muaj kev cuam tshuam los ntawm dej kub thiab nthuav tawm cov kab mob zoo tshaj plaws ntawm cov dej tsis zoo.

Ozone Disinfection
Ozone, ib qho zoo oxidizer, muaj broad-spectrum microbial eradication.Txawm li cas los xij, nws tsis muaj lub neej ntev, ruaj khov, thiab yuav tsum muaj kev txawj ntse rau kev saib xyuas thiab tswj, feem ntau yog siv hauv cov dej ntim khoom.

Hauv qab no yog qee cov qauv thoob ntiaj teb rau kev haus dej tua kab mob

Cov tshuaj chlorine dawb uas yuav tsum tau muaj yog: lub sij hawm sib cuag nrog dej ≥ 30 feeb, lub Hoobkas dej thiab lub davhlau ya nyob twg dej txwv ≤ 2 mg / L, Hoobkas dej margin ≥ 0.3 mg / L, thiab cov dej davhlau ya nyob twg ≥ 0.05 mg / L.

Tag nrho cov tshuaj chlorine index yuav tsum yog: lub sij hawm sib cuag nrog dej ≥ 120 feeb, txwv tus nqi ntawm lub Hoobkas dej thiab dej davhlau ya nyob twg ≤ 3 mg / L, Hoobkas dej tshaj ≥ 0.5 mg / L, thiab cov dej ntws tawm ≥ 0.05 mg / L.

Cov kev cai ozone index yuav tsum yog: lub sij hawm sib cuag nrog dej ≥ 12 feeb, lub Hoobkas dej thiab lub davhlau ya nyob twg dej txwv ≤ 0.3 mg / L, cov dej seem seem ≥ 0.02 mg / L, yog tias siv lwm txoj kev siv tshuaj tua kab mob, cov tshuaj tua kab mob txwv thiab cov seem seem yuav tsum tau ua raws.

Chlorine dioxide index yuav tsum yog: lub sij hawm sib cuag nrog dej ≥ 30 feeb, lub Hoobkas dej thiab lub davhlau ya nyob twg dej txwv ≤ 0.8 mg / L, lub Hoobkas dej tshuav ≥ 0.1 mg / L, thiab cov dej tshuav nyiaj li cas ≥ 0.02 mg / L.
