Ukuthetha jikelele,unxunguphaloibhekisa kwiunxunguphalongamanzi.Ngokukodwa, kuthetha ukuba umzimba wamanzi uqulethe izinto ezimisiweyo, kwaye ezi
izinto ezimisiweyo ziya kuthintelwa xa ukukhanya kudlula.Eli nqanaba lothintelo libizwa ngokubaunxunguphaloixabiso.Izinto eziqinileyo ezinqunyanyisiweyokunye ne-colloids
njengomhlaba, intlenga, i-organic matter ecolekileyo, i-inorganic matter, kunye neplankton emanzini zinokwenza amanzi axokomezeke kwaye abonise ukungqubana okuthile.
Ngokutsho kweuhlalutyo lomgangatho wamanzi, iunxunguphaloeyenziwe ngu-1 mg SiO2 kwi-1L yamanzi nguMgangatho omnyeunxunguphaloiyunithi, ekubhekiswa kuyo njenge-1 degree.
Ngokubanzi, kokukhona iphezuluunxunguphalo, kokukhona siguquguquka isicombululo.
Umgaqo-siseko wokulinganisa we-turbidity:
Umtha wokukhanya ohambelanayo usasaza kulwelo olucacileyo.Ukuba akukho zincinci ezimisiweyo kulwelo, umqadi awuyi kutshintsha indlela xa uhamba
kumgca othe tye;okanye hayi).Oku kubumba into eyaziwa ngokuba kukukhanya okusasazekayo.Amasuntswana amaninzi (phezuluunxunguphalo) kokukhona ukusasazwa kokukhanya kuqatha.Unxunguphalo
kulinganiswa ngesixhobo esibizwa ngokuba yi-nephelometer.I-nephelometer ithumela ukukhanya ngecandelo lesampulu kwaye ilinganise ukuba kungakanani ukukhanya okusasazwe ngako
amasuntswana emanzini kwi-angle ye-90 ° kwisibane sesiganeko.Le ndlela yokulinganisa ukukhanya okuthe saa ibizwa ngokuba yindlela yokusasaza.Nayiphi na inyanisounxunguphalomayibe
kulinganiswe ngale ndlela.Iimitha ye-turbidityifanelekile kwimilinganiselo yomibini yentsimi kunye neyebhubhoratri, kunye nokubeka iliso ngokuqhubekayo yonke imini.Ii-turbidimeters
inokusetwa ukukhalisa i-alam xa ilinganisiweunxunguphaloamaxabiso angaphezulu kwemigangatho yokhuseleko.
Iindlela zokulinganisa:
1. Unxunguphaloinokulinganiswa ngendlela ye-nephelometric okanye indlela yokukhanya esasaziweyo.E-China, i-turbidimetry isetyenziselwa ukuzimisela.Isampulu yamanzi iyathelekiswa
neunxunguphaloisisombululo esisezantsi esilungiswe ngekaolin, kunye neunxunguphaloAkukho phezulu, kwaye kumiselwe ukuba i-1 mg ye-silicon dioxide kwilitha enye yamanzi adibeneyo.
aunxunguphalo iyunithi.Kubaiindlela ezahlukeneyo zokulinganisa okanye izinto ezisemgangathweni ezahlukeneyo, amaxabiso afunyenweyo omlinganiselo we-turbidity awahambelani ngokuyimfuneko.Inqanaba le
unxunguphalongokubanziandinakoukuchaza ngokuthe ngqo iqondo longcoliseko lomgangatho wamanzi, kodwa ukwandaunxunguphalookubangelwa ubomi bomntu kunye nogutyulo lwamashishini lubonisa
ukuba umgangatho wamanzi uye wehla.
2. Unxunguphaloinokulinganiswa nge-turbidimeter.I-nephelometer ithumela ukukhanya ngecandelo lesampulu kwaye ilinganise ukuba kungakanani na ukukhanya okusasazwe ngamasuntswana emanzini.
kwi-90 °i-engile kwisibane sesiganeko.Le ndlela yokulinganisa ukukhanya okuthe saa ibizwa ngokuba yindlela yokusasaza.Nayiphi na inyanisounxunguphalokufuneka ilinganiswe ngolu hlobo.Iimitha ye-turbidityyi
zilungele zombiniimilinganiselo yentsimi kunye nelebhu, kunye nokubeka iliso rhoqo ngewotshi.Ii-turbidimetersinokusetwa ukukhalisa i-alam xa ilinganisiwe
unxunguphalo amaxabiso angaphezulu kwemigangatho yokhuseleko.
3. Unxunguphaloinokuqikelelwa ngokusebenzisa i-colorimeter okanye i-spectrophotometer ukulinganisa iqondo lokuthotywa kokukhanya okugqithisiweyo okubangelwa kukuthintelwa.
yeamasuntswana kwiisampuli.Nangona kunjalo, ii-arhente ezilawulayo azibuboni ubunyani bale ndlela, kwaye ayihlangabezani nenkcazo yeAmerican Public Health Association.
unxunguphalo.
4. Umlinganiselo wokuhanjiswa kokukhanya uchaphazeleka lula ngokuphazamiseka okufana nokufunxa umbala okanye ukufunxwa kwamasuntswana.Ngaphaya koko, bekungekho lunxulumano phakathi kokuhanjiswa kokukhanya kunye neziphumo ezilinganiswe ngemilinganiselo yokukhanya okuthe saa.Nangona kunjalo, kwinqanaba elithile i-colorimeter kunye ne-spectrophotometer imilinganiselo inokusetyenziselwa ukumisela ubukhulu beunxunguphalokwiinkqubo zokunyanga amanzi okanye ulawulo lwenkqubo.
