Kev tswj xyuas cov dej zoo ntawm lub pas dej da dej yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab kev lom zem ua luam dej.Ib qho tshuaj lom neeg ua haujlwm rau kev kho dej yogAluminium Sulfate, ib qho chaw paub txog nws cov txiaj ntsig hauv kev nthuav dav thiab ntsuas dej hauv pas dej.
Aluminium sulfate, tseem hu ua alum, tuaj yeem ua cov flocculants hauv kev kho dej hauv pas dej da dej, pab tshem tawm cov khoom tshem tawm thiab cov impurities.Qhov no tuaj yeem ua rau cov dej ntshiab thiab txhim khu kev zoo nkauj thiab kev nyab xeeb ntawm lub pas dej.
Txheej txheem qhia meej:
Aluminium sulfate ntxiab tshem tawm cov khoom, xws li av, khib nyiab, thiab kab mob, ua rau lawv nyob rau hauv qab ntawm lub pas dej.Kev siv cov txhuas sulfate tsis tu ncua pab tswj cov dej kom pom tseeb thiab tiv thaiv kev sib sau ntawm cov khoom tsis zoo.
Kev cai pH:
Dhau li ntawm nws cov khoom qhia meej, aluminium sulfate kuj cuam tshuam rau pH qib ntawm cov dej hauv pas dej.Xyuas kom meej tias pH ntawm lub pas dej da dej yog nyob rau hauv thaj tsam ntawm 7.2 txog 7.6 thiab tag nrho alkalinity nyob rau hauv thaj tsam ntawm 80 mus rau 120 ppm.Yog tias tsim nyog, kho pH siv pH Minus lossis pH Plus thiab kho tag nrho cov alkalinity siv pH Minus thiab TA thawv.Tsis txhob ntxiv aluminium sulfate thaum siv lub pas dej ua ke.
Kev txiav txim siab thiab cov lus qhia:
Kev Siv Kom Zoo:
Nws yog ib qho tseem ceeb kom ua raws li cov lus pom zoo noj thaum siv txhuas sulfate hauv lub pas dej da dej.Cov koob tshuaj ib txwm yog 30-50 mg / L.Yog tias cov dej qias neeg dhau lawm, yuav tsum tau noj ntau dua.Kev noj ntau dhau yuav ua rau tus nqi pH poob ntau dhau, ua rau muaj kev phom sij rau cov khoom siv hauv pas dej da dej, thiab tseem yuav txo cov nyhuv flocculation.Underdosing, ntawm qhov tod tes, yuav tsis muab cov lus qhia meej dej zoo.
Kev saib xyuas tsis tu ncua:
Kev ntsuas tsis tu ncua ntawm pas dej da dej, suav nrog pH, alkalinity, thiab aluminium sulfate qib, yog qhov tseem ceeb.Qhov no ua kom cov dej nyob hauv qhov kev pom zoo thiab pab tiv thaiv txhua yam teeb meem tshwm sim los ntawm kev tsis sib haum tshuaj.
Aluminium sulfate yuav tsum tau siv kom raug raws li cov lus qhia ntawm kev siv.Nws pab tshem tawm cov khoom tshem tawm thiab sib npaug pH qhov tseem ceeb, thiab ua lub luag haujlwm tseem ceeb hauv kev tshem tawm cov dej impurities ntawm lub pas dej.Lub pas dej ua ke yuav tsum tau sim ua ntu zus, thiab ua raws li txoj hauv kev siv kom nyab xeeb rau hauv pas dej da dej.
