Qhov sib txawv tseem ceeb ntawm cov tshuaj dawb thiab cov tshuaj chlorine tag nrho yog tias cov tshuaj dawb dawb yog cov tshuaj chlorine uas tuaj yeem ua rau cov kab mob pathogenic muaj nyob rau hauv dej thaum tag nrho cov tshuaj chlorine yog qhov sib xyaw ntawm cov tshuaj chlorine thiab dawb chlorine. Tus nqi ntawm cov tshuaj dawb dawb yog ib txwm qis dua tus nqi ntawm tag nrho cov tshuaj chlorine.
Cov tshuaj chlorine sib xyaw yog cov tshuaj chlorine uas cuam tshuam nrog cov tshuaj nitrogen uas muaj nyob hauv dej. Yog li, cov tshuaj chlorine no tsis muaj rau cov txheej txheem tshuaj tua kab mob ntawm cov dej. Qhov no txhais tau hais tias lub sij hawm tag nrho cov tshuaj chlorine muab tag nrho cov tshuaj chlorine uas muaj thiab tsis muaj rau cov kab mob pathogenic (mob ua rau) cov kab mob hauv dej.
Dab tsi yog chlorine dawb?
Cov tshuaj dawb dawb yog cov tshuaj chlorine uas tuaj yeem ua rau cov kab mob muaj kab mob nyob hauv dej. Nws yog qhov concentration ntawm chlorine nyob rau hauv daim ntawv ntawm yaj chlorine gas (Cl 2), hypochlorous acid (HOCl) thiab hypochlorite ions (OCl–). Ntxiv mus, hypochlorous acid feem ntau pab txhawb rau qhov ntsuas no vim tias hypochlorous acid muaj cov nyhuv oxidizing uas yog kaum npaug siab dua li hypochlorite ions. Peb tuaj yeem ntsuas qhov concentration ntawm cov dej hauv pas dej da dej vim tias nws yog cov tshuaj chlorine uas muaj los ntxuav cov dej hauv pas dej. Piv txwv li: cov ntsiab lus chlorine dawb hauv pas dej da dej yog tsim nyog nyob rau hauv thaj tsam ntawm 1-3 ppm.
Daim duab 01: Cov tshuaj tua kab mob chlorine rau cov pas dej da dej
Peb yuav tsum ntsuas cov tshuaj chlorine dawb hauv dej vim peb yuav tsum tau saib xyuas cov ntsiab lus chlorine hauv dej (vim cov tshuaj tua kab mob, cov tshuaj chlorine tau siv los ntawm dej). Muaj ob txoj hauv kev ntsuas cov tshuaj dawb chlorine; kuaj colorimetric thiab amerometric kuaj. Colorimetric kev ntsuam xyuas yog automated systems; nws xav tau cov qauv thiab cov reagents tshwj xeeb uas tuaj yeem ua rau muaj xim loj hlob hauv cov qauv. Kev ntsuam xyuas amperometric kuj tseem muaj cov tshuab ua haujlwm uas muaj cov tshuaj chlorine rugged uas tau txais txiaj ntsig rau pH.
chlorine tag nrho yog dab tsi?
Tag nrho cov tshuaj chlorine yog qhov sib xyaw ntawm cov tshuaj chlorine thiab cov tshuaj dawb dawb. Cov tshuaj chlorine sib xyaw yog cov tshuaj chlorine uas tsis muaj rau cov txheej txheem dej huv. Hauv lwm lo lus, nws yog qhov ntsuas ntawm qhov concentration ntawm cov tshuaj chlorine uas ua ke nrog nitrogen-muaj cov tebchaw hauv dej. Yog li, cov tshuaj chlorine no tsis muaj rau cov txheej txheem tshuaj tua kab mob.
Cov tshuaj muaj nitrogen hauv dej yog ammonia thiab organic amines. Cov tebchaw no muaj nyob hauv cov dej ntuj lossis cov dej tsis huv. Txawm li cas los xij, cov nroj tsuag kho dej qee zaum txhob txwm tshaj tawm ammonia rau hauv dej txhawm rau tsim cov tshuaj chloramines (cov txheej txheem no yog chloramination), uas kuj yog tshuaj tua kab mob.
Dab tsi yog qhov txawv ntawm Dawb chlorine thiab tag nrho cov chlorine?

Summary – Dawb chlorine vs Total chlorine
Cov tshuaj chlorine uas muaj cov tshuaj muaj ntau heev ua cov tshuaj bleaching thiab tshuaj tua kab mob. Nws tuaj yeem ua raws li oxidizer kom oxidize ntau yam teeb meem hauv dej. Tsis tas li ntawd, nws tuaj yeem txhim kho qhov saj ntawm cov dej haus. Cov tshuaj chlorine dawb thiab tag nrho cov tshuaj chlorine yog ob hom kev ntsuas peb coj los xyuas kom meej cov dej zoo. Qhov sib txawv ntawm cov tshuaj dawb dawb thiab tag nrho cov tshuaj chlorine yog tias cov tshuaj dawb dawb yog cov tshuaj chlorine uas tuaj yeem ua rau cov kab mob pathogenic microorganisms muaj nyob rau hauv dej whereas tag nrho cov tshuaj chlorine yog qhov sib xyaw ntawm cov tshuaj chlorine thiab dawb chlorine.
