Ukubulala iintsholongwane emanzini okusela kufeza injongo ebalulekileyo—ukuphelisa uninzi lweentsholongwane eziyingozi, eziquka iintsholongwane, iintsholongwane, kunye neprotozoa, ukuthintela ukwanda kwezifo ezisemanzini.Ngelixa ukubulala iintsholongwane kungazisusi zonke iintsholongwane, kuqinisekisa ukuba umngcipheko wezifo ezisemanzini uyathotywa ukuya kumanqanaba abonwa amkelekile phantsi kwemigangatho yebhayoloji.Ukuvala inzala, kwelinye icala, kubhekisa ekupheliseni zonke iintsholongwane ezikhoyo emanzini, ngelixa ukubulawa kweentsholongwane kujolise kwinxalenye enkulu yeentsholongwane ze-pathogenic, ukunciphisa umngcipheko onxulumene nezigulo eziphuma emanzini.

I-Evolution ye-Disinfection Techniques
Phambi kwenkulungwane ye-19, xa kwasekwa ithiyori ye-bacterial pathogenic, ivumba lalithathwa njengesixhobo sosulelo lwezifo, liphembelela uphuhliso lweendlela zokubulala iintsholongwane emanzini kunye nogutyulo.

Iindlela zokubulala iintsholongwane kumanzi okusela
Ukubulala iintsholongwane ngokwaseMzimbeni
Iindlela zomzimba ezifana nokufudumeza, ukuhluzwa, ukusasazeka kwemitha ye-ultraviolet (UV) kunye nokukhanya kwemitha ziyasetyenziswa.Amanzi abilayo axhaphakile, asebenza kunyango oluncinci, ngelixa iindlela zokuhluza njengesanti, iasbestos, okanye izihluzi zefiber zeviniga zisusa iibhaktheriya ngaphandle kokuzibulala.Imitha ye-UV, ngakumbi phakathi koluhlu lwe-240-280nm, ibonisa iipropati ezinamandla zokubulala iintsholongwane, ezilungele ubungakanani bamanzi amancinci, zisebenzisa izibulala-ntsholongwane ze-UV ezithe ngqo okanye zohlobo lwemikhono.

Ukukhutshwa kweentsholongwane kwi-UV
Imitha ye-UV ephakathi kwe-200-280nm ibulala ngokufanelekileyo iintsholongwane ngaphandle kokusebenzisa imichiza, ifumana udumo ngokusebenza kwayo ekulawuleni ii-arhente ezibangela izifo.

Ukubulala iintsholongwane kwiMichiza
Amachiza okutshabalalisa iintsholongwane aquka iklorination, ikloramines, iklorini diokside, kunye ne-ozone.

I-Chlorine Compounds
I-Chlorination, indlela eyamkelwa ngokubanzi, ibonisa iimpawu ezinamandla, ezizinzileyo, kunye neendleko ezisebenzayo ze-germicidal, ezisetyenziswa ngokufanelekileyo kunyango lwamanzi.I-Chloramines, i-derivative ye-chlorine kunye ne-ammonia, igcina incasa yamanzi kunye nombala kunye nomthamo ophantsi we-oxidative kodwa ifuna iinkqubo ezinzima kunye nokugxila okuphezulu.

I-Chlorine Dioxide
Ithathwa njengesizukulwana sesine sokubulala iintsholongwane, iklorini diokside yodlula iklorini kwizinto ezininzi, ibonisa isibulali-ntsholongwane esingcono, ukususwa kwencasa, kunye nemveliso ephantsi ye-carcinogenic.Ayichatshazelwa kancinci bubushushu bamanzi kwaye ibonisa iziphumo eziphezulu ze-bactericidal kumanzi akumgangatho ophantsi.

I-Ozone Disinfection
I-ozone, i-oxidizer esebenzayo, inikezela ngokupheliswa kwe-microbial ebanzi.Nangona kunjalo, ayinabo ubomi obude, uzinzo, kwaye ifuna ubuchwephesha bokubeka iliso nokulawula, ubukhulu becala busetyenziswa kwimveliso yamanzi asebhotileni.

Apha ngezantsi kukho imigangatho yamazwe ngamazwe yokubulala iintsholongwane emanzini okusela

Iimfuno zesalathisi ze-chlorine zamahhala zezi: ixesha lokuqhagamshelana namanzi ≥ imizuzu ye-30, amanzi asefektri kunye nomda wamanzi we-terminal ≤ 2 mg / L, umda wamanzi wefektri ≥ 0.3 mg / L, kunye nomda wamanzi we-terminal ≥ 0.05 mg / L.

Iimfuno zesalathisi se-chlorine zizonke zezi: ixesha lokudibanisa ngamanzi ≥ imizuzu eyi-120, ixabiso elilinganiselweyo lamanzi asefektri kunye namanzi okugqibela ≤ 3 mg / L, i-surplus yamanzi yefektri ≥ 0.5 mg / L, kunye ne-terminal water surplus ≥ 0.05 mg / L.

Iimfuno zesalathisi se-ozone zezi: ixesha lokuqhagamshelana namanzi ≥ imizuzu eyi-12, amanzi asefektri kunye nomda wamanzi we-terminal ≤ 0.3 mg / L, i-terminal water residual ≥ 0.02 mg / L, ukuba ezinye iindlela ezidityanisiweyo zokubulala iintsholongwane zisetyenzisiweyo, umda we-disinfectant kunye nentsalela. iimfuno kufuneka kuhlangatyezwane nazo.

Iimfuno zesalathisi se-chlorine dioksidi zi: ixesha lokuqhagamshelana namanzi ≥ imizuzu ye-30, amanzi e-factory kunye ne-terminal water limit ≤ 0.8 mg / L, ibhalansi yamanzi yefektri ≥ 0.1 mg / L, kunye ne-terminal balance balance ≥ 0.02 mg / L.
