1. Lub qhov ntawm kais dej cog qhov, sedimentation phiab thiab lwm yam kauj ruam on-line xyuas thiab lwm yam ntawm turbidity.
2. Cov dej phwj tuaj kho, kev tshuaj xyuas hauv online ntawm turbidity ntawm ntau hom kev lag luam tsim cov txheej txheem dej thiab cov txheej txheem dej khib nyiab.
Turbidity, ib qho kev ntsuas ntawm huab cua hauv cov kua, tau raug lees paub tias yog ib qho yooj yim thiab yooj yim qhia txog dej zoo.Nws tau raug siv los saib xyuas cov dej haus, suav nrog cov uas tsim los ntawm kev pom tau ntau xyoo lawm.Kev ntsuas turbidity suav nrog kev siv lub teeb pom kev zoo, nrog cov yam ntxwv uas tau hais tseg, los txiav txim seb qhov muaj pes tsawg leeg ntawm cov khoom muaj feem muaj nyob hauv dej lossis lwm cov kua dej.Lub teeb beam yog hu ua qhov teeb meem teeb beam.Cov khoom muaj nyob hauv dej ua rau qhov teeb meem teeb pom kev tawg tawg thiab lub teeb tawg tawg no raug kuaj pom thiab txheeb xyuas qhov txheeb ze rau tus qauv calibration.Qhov siab dua qhov ntau ntawm cov khoom siv uas muaj nyob rau hauv ib qho qauv, qhov ntau dua qhov tawg ntawm qhov teeb meem teeb pom kev zoo thiab qhov siab dua qhov tshwm sim turbidity.
Ib qho me me hauv ib qho qauv uas dhau los ntawm qhov teeb meem teeb meem teeb meem (feem ntau yog lub teeb incandescent, lub teeb emitting diode (LED) lossis laser diode), tuaj yeem ua rau tag nrho cov turbidity hauv cov qauv.Lub hom phiaj ntawm kev pom yog kom tshem tawm cov khoom ntawm ib qho qauv.Thaum pom cov tshuab ua haujlwm tau zoo thiab saib xyuas nrog lub turbidimeter, turbidity ntawm cov effluent yuav raug ntsuas los ntawm qhov ntsuas qis thiab ruaj khov.Qee qhov turbidimeters ua haujlwm tsawg dua ntawm cov dej huv huv, qhov twg qhov ntau thiab tsawg ntawm cov particle suav qis heev.Rau cov turbidimeters uas tsis muaj rhiab heev ntawm cov qib qis no, turbidity hloov uas tshwm sim los ntawm kev lim dej tuaj yeem ua rau me me uas nws dhau los ua qhov tsis sib xws ntawm turbidity baseline suab nrov ntawm lub ntsuas.
Lub suab nrov hauv paus no muaj ntau qhov chaw suav nrog cov suab nrov hauv lub cev (suab nrov hauv hluav taws xob), ntsuas lub teeb pom kev, suab nrov nrov, thiab suab nrov hauv lub teeb pom kev nws tus kheej.Cov kev cuam tshuam no yog qhov ntxiv thiab lawv dhau los ua qhov tseem ceeb ntawm cov lus teb tsis tseeb turbidity thiab tuaj yeem cuam tshuam tsis zoo rau cov ntsuas ntsuas ntsuas.
Cov ntsiab lus ntawm cov qauv hauv kev ntsuas turbidimetric yog qhov nyuaj ib feem los ntawm ntau hom qauv hauv kev siv thiab siv tau rau kev tshaj tawm cov hom phiaj los ntawm cov koom haum xws li USEPA thiab Standard Methods, thiab ib feem los ntawm cov ntsiab lus lossis cov ntsiab lus siv rau lawv.Nyob rau hauv 19th Edition ntawm Standard Methods rau Kev Ntsuam Xyuas Dej thiab Dej Num, kev qhia meej tau ua los ntawm kev txhais cov qauv piv rau theem nrab.Standard Methods txhais cov txheej txheem tseem ceeb raws li ib qho uas tau npaj los ntawm tus neeg siv los ntawm cov khoom siv raw khoom, siv cov txheej txheem meej thiab nyob rau hauv kev tswj hwm ib puag ncig.Hauv turbidity, Formazin tsuas yog lees paub qhov tseeb thawj tus qauv thiab tag nrho lwm cov qauv raug taug qab mus rau Formazin.Tsis tas li ntawd, ntsuas algorithms thiab specifications rau turbidimeters yuav tsum tau tsim nyob ib ncig ntawm no thawj tus qauv.
Standard Methods tam sim no txhais cov qauv theem nrab raws li cov qauv no ib lub chaw tsim khoom (lossis ib lub koom haum kuaj kev ywj pheej) tau ntawv pov thawj los muab cov ntsuas ntsuas ntsuas qhov sib npaug (hauv qee qhov txwv) rau cov txiaj ntsig tau txais thaum lub ntsuas ntsuas ntsuas nrog cov neeg siv npaj Formazin cov qauv (cov qauv tseem ceeb).Ntau yam qauv uas tsim nyog rau kev ntsuas yog muaj, suav nrog cov khoom lag luam raug tshem tawm ntawm 4,000 NTU Formazin, stabilized Formazin suspensions (StablCal ™ Stabilized Formazin Standards, uas tseem hu ua StablCal Standards, StablCal Solutions, lossis StablCalions ntawm kev lag luam susphens), thiab ntawm styrene divinylbenzene copolymer.
