Vim li cas peb thiaj ntxiv Aluminium Sulfate rau hauv dej?

Kev kho dej yog cov txheej txheem tseem ceeb uas ua kom muaj dej huv thiab nyab xeeb rau ntau lub hom phiaj, suav nrog kev haus dej, kev lag luam, thiab kev ua liaj ua teb.Ib qho kev coj ua hauv kev kho dej muaj kev sib ntxiv ntawmAluminium Sulfate, kuj hu ua alum.Qhov kev sib xyaw no ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov dej zoo los ntawm kev daws cov teeb meem tshwj xeeb hauv kev muab dej.Hauv tsab xov xwm no, peb yuav tshawb txog cov laj thawj tom qab ntxiv aluminium sulfate rau dej thiab cov txiaj ntsig nws coj.

Coagulation thiab Flocculation:

Ib qho laj thawj tseem ceeb rau kev ntxiv aluminium sulfate rau dej yog nws cov txiaj ntsig hauv coagulation thiab flocculation.Coagulation yog hais txog cov txheej txheem ntawm destabilizing tshem tawm cov khoom hauv dej, ua rau lawv sib sau ua ke.Flocculation cuam tshuam txog kev tsim cov khoom loj, hu ua flocs, los ntawm cov khoom coagulated.Aluminium sulfate ua raws li coagulant, pab tshem tawm cov impurities xws li tshem tawm cov khib nyiab, organic teeb meem, thiab kab mob.

Tshem tawm ntawm Turbidity:

Turbidity, tshwm sim los ntawm kev tshem tawm cov khoom hauv dej, tuaj yeem cuam tshuam nws qhov pom tseeb thiab zoo nkauj zoo nkauj.Aluminium sulfate pab txo qis turbidity los ntawm kev txhawb nqa cov aggregation ntawm cov khoom no.Cov flocs tsim nyob rau hauv, tso cai rau kom yooj yim pom thiab muab dej ntshiab.

Kev hloov pH:

Aluminium sulfate kuj tseem txhawb nqa pH hloov hauv kev kho dej.Nws ua raws li pH stabilizer, pab tswj cov dej acidity lossis alkalinity hauv qhov xav tau.Cov qib pH kom zoo yog qhov tseem ceeb rau kev ua tau zoo ntawm lwm cov txheej txheem kho thiab xyuas kom meej tias cov dej kho tau raws li cov qauv kev cai.

Txo phosphorus:

Phosphorus yog cov khoom noj muaj txiaj ntsig uas tuaj yeem ua rau muaj kuab paug hauv dej thiab eutrophication thaum muaj ntau dhau.Aluminium sulfate tuaj yeem pab txo cov qib phosphorus los ntawm kev tsim cov tshuaj insoluble nrog nws.Qhov no pab tiv thaiv kev loj hlob ntawm algae thiab lwm yam dej tsis zoo, txhim kho dej zoo.

Txhim kho qhov chaw nyob hauv Sedimentation Basins:

Hauv cov nroj tsuag kho dej, cov bass sedimentation yog siv los tso cai rau cov khoom nyob hauv qab, yooj yim tshem tawm lawv.Aluminium sulfate pab txhim kho kev daws teeb meem los ntawm kev txhawb nqa kev tsim cov floc loj dua thiab ntom ntom.Qhov no ua rau muaj txiaj ntsig ntau dua sedimentation, txo cov load ntawm cov txheej txheem tom ntej.

Qhov sib ntxiv ntawm aluminium sulfate rau dej ua haujlwm rau ntau lub hom phiaj hauv kev kho dej, suav nrog coagulation, flocculation, turbidity tshem tawm, pH hloov, thiab txo phosphorus.Cov txheej txheem no koom ua ke los tsim cov dej huv thiab nyab xeeb rau kev siv thiab ntau yam kev siv hauv kev lag luam.Kev nkag siab txog lub luag haujlwm ntawm txhuas sulfate hauv kev kho dej yog qhov tseem ceeb rau kev ua kom zoo ntawm cov txheej txheem kho thiab ua kom cov dej zoo rau cov zej zog.
