Nws yog qhov tseeb tias ntxivChlorineyuav cuam tshuam rau pH ntawm koj lub pas dej. Tab sis seb pH qib nce lossis txo qis yog nyob ntawm seb tusTshuaj tua kab mob chlorinentxiv rau lub pas dej ua ke yog alkaline lossis acidic. Yog xav paub ntxiv txog cov tshuaj tua kab mob chlorine thiab lawv txoj kev sib raug zoo rau pH, nyeem rau.
Qhov tseem ceeb ntawm chlorine Disinfection
Chlorine yog cov tshuaj siv dav tshaj plaws rau kev tua kab mob hauv pas dej. Nws yog qhov tsis sib haum xeeb hauv nws cov txiaj ntsig ntawm kev tua cov kab mob phem, kab mob, thiab algae, ua rau nws yog qhov tseem ceeb hauv kev saib xyuas kev huv ntawm pas dej. chlorine tuaj nyob rau hauv ntau hom, xws li sodium hypochlorite (kua), calcium hypochlorite (khoom), thiab dichlor (hmoov). Txawm li cas los xij ntawm daim ntawv siv, thaum chlorine ntxiv rau hauv pas dej ua ke, nws reacts tsim hypochlorous acid (HOCl), ib qho tshuaj tua kab mob uas ua rau cov kab mob tsis zoo.
Puas ntxiv chlorine qis pH?
1. Sodium hypochlorite:Daim ntawv no ntawm chlorine, feem ntau yog ua kua, feem ntau hu ua bleach lossis kua chlorine. Nrog pH ntawm 13, nws yog alkaline. Nws yuav tsum tau ntxiv cov kua qaub kom lub pas dej ua ke nruab nrab.
2. Calcium hypochlorite:Feem ntau tuaj nyob rau hauv granules los yog ntsiav tshuaj. Feem ntau hu ua "calcium hypochlorite", nws kuj muaj pH siab. Nws qhov sib ntxiv tuaj yeem pib nce pH ntawm lub pas dej, txawm hais tias cov nyhuv tsis zoo li sodium hypochlorite.
3. TrichlorthiabDichlor: Cov no yog acidic (TCCA muaj pH ntawm 2.7-3.3, SDIC muaj pH ntawm 5.5-7.0) thiab feem ntau yog siv rau hauv ntsiav tshuaj lossis granule daim ntawv. Ntxiv trichlor lossis dichlor rau hauv lub pas dej ua ke yuav txo cov pH, yog li hom tshuaj tua kab mob chlorine no feem ntau yuav txo qis pH tag nrho. Cov nyhuv no yuav tsum tau saib xyuas kom tsis txhob muaj cov dej hauv pas dej ua kua qaub dhau.
Lub luag haujlwm ntawm pH hauv pas dej da dej
pH yog qhov tseem ceeb hauv kev ua haujlwm ntawm chlorine ua cov tshuaj tua kab mob. Qhov pH zoo tshaj plaws rau cov pas dej da dej feem ntau yog nyob nruab nrab ntawm 7.2 - 7.8. Qhov no ua kom ntseeg tau tias cov tshuaj chlorine ua haujlwm zoo thaum ua luam dej. Ntawm pH qib qis dua 7.2, chlorine ua dhau heev lawm thiab tuaj yeem ua rau khaus ua luam dej qhov muag thiab tawv nqaij. Hloov pauv, ntawm pH qib siab tshaj 7.8, chlorine poob nws cov txiaj ntsig, ua rau lub pas dej ua rau cov kab mob thiab algae loj hlob.
Ntxiv cov tshuaj chlorine cuam tshuam rau pH, thiab khaws pH hauv qhov zoo tagnrho yuav tsum tau saib xyuas kom zoo. Txawm hais tias chlorine nce lossis txo pH, ntxiv pH adjuster yog qhov tseem ceeb kom muaj kev sib npaug.
Dab tsi pH adjusters ua
pH adjusters, los yog pH balancing chemicals, yog siv los kho cov pH ntawm cov dej mus rau qhov xav tau. Muaj ob lub ntsiab ntawm pH adjusters siv hauv pas dej da dej:
1. pH nce (Piv txwv): Sodium carbonate (soda tshauv) yog ib qho uas nquag siv pH nce. Thaum pH qis dua qib tau pom zoo, nws tau ntxiv los txhim kho pH thiab rov qab sib npaug.
2. pH Reducers (Acids): Sodium bisulfate yog ib qho siv pH reducer. Thaum pH siab dhau lawm, cov tshuaj no tau ntxiv kom txo qis rau qhov zoo tshaj plaws.
Hauv cov pas dej uas siv cov tshuaj chlorine acidic, xws li trichlor lossis dichlor, feem ntau yuav tsum muaj pH nce ntxiv los tiv thaiv qhov txo qis ntawm pH. Hauv cov pas dej uas siv sodium los yog calcium hypochlorite, yog tias pH siab dhau tom qab chlorination, pH reducer yuav tsum tau txo qis pH. Tau kawg, qhov kawg suav ntawm seb puas siv lossis tsis siv, thiab siv ntau npaum li cas, yuav tsum yog raws li cov ntaub ntawv tshwj xeeb ntawm tes.
Ntxiv chlorine rau hauv pas dej ua ke cuam tshuam rau nws cov pH, nyob ntawm seb hom tshuaj chlorine siv.Cov tshuaj tua kab mob chlorineuas muaj acidic ntau dua, xws li trichlor, yuav txo qis pH, thaum ntau cov tshuaj tua kab mob alkaline chlorine, xws li sodium hypochlorite, nce pH. Kev saib xyuas lub pas dej kom zoo yuav tsum tsis yog tsuas yog ntxiv cov tshuaj chlorine rau cov tshuaj tua kab mob xwb, tab sis kuj tseem ua tib zoo saib xyuas thiab hloov pH siv lub pH adjuster. Txoj cai sib npaug ntawm pH ua kom cov tshuaj tua kab mob muaj zog ntawm cov tshuaj chlorine ua kom tiav yam tsis muaj kev cuam tshuam rau kev ua luam dej. Los ntawm kev sib npaug ntawm ob, cov tswv hauv pas dej ua ke tuaj yeem ua kom huv, nyab xeeb, thiab xis nyob ib puag ncig ua luam dej.
