Aluminium sulfate dej kho

Aluminium sulfate dej kho yog ib qho tseem ceeb ntawm kev tiv thaiv ib puag ncig, thiab ntau yam kuab paug hauv kev kho dej ua rau muaj kev hem thawj rau ib puag ncig thiab tib neeg kev noj qab haus huv. Aluminium sulfate yog ib qho tshuaj kho dej uas nquag siv nrog kev ua haujlwm zoo ntawm flocculation thiab sedimentation, uas tuaj yeem tshem tawm cov khib nyiab thiab chromaticity hauv cov dej khib nyiab.

Aluminium sulfate, nrog rau cov tshuaj formula Al2 (SO4) 3, yog ib qho inorganic compound feem ntau pom nyob rau hauv daim ntawv ntawm dawb crystals. Nws muaj dej solubility zoo thiab ruaj khov, thiab tuaj yeem yaj sai sai hauv dej los tsim cov txhuas ions thiab sulfate ions. Hauv kev kho cov dej txhuas sulfate, lub luag haujlwm tseem ceeb ntawm txhuas sulfate yog txhawm rau txhawm rau tshem tawm cov khib nyiab thiab cov chromatic cov khoom hauv cov dej khib nyiab rau hauv cov khoom loj dua los ntawm flocculation thiab sedimentation, yog li yooj yim rau kev lim dej tom qab thiab kev kho sedimentation.

1. Kho tus nqi pH: Tus nqi pH ntawm cov dej khib nyiab muaj qee yam cuam tshuam rau cov nyhuv flocculation ntawm txhuas sulfate. Feem ntau hais lus, thaum tus nqi pH nyob nruab nrab ntawm 6.0 thiab 7.0, cov nyhuv flocculation ntawm txhuas sulfate zoo dua. Yog li ntawd, ua ntej siv txhuas sulfate, nws yog ib qhov tsim nyog los tswj cov pH nqi ntawm cov dej khib nyiab los ntawm kev ntxiv cov kua qaub-puag regulators.

2. Aluminium sulfate dej kev kho mob pub mis: Raws li qhov teeb meem tiag tiag, yaj ib qho tsim nyog ntawm txhuas sulfate hauv dej los tsim ib qho kev daws teeb meem ntawm txhuas sulfate. Tom qab ntawd sib npaug ntxiv cov tshuaj rau cov dej khib nyiab kom kho, feem ntau yog nplawm lossis txau.

3. Sib tov thiab sedimentation: Nyob rau hauv cov txheej txheem ntawm kev sib tov aluminium sulfate nrog dej phwj tuaj, txhuas ions nyob rau hauv aluminium sulfate react chemically nrog suspended solids thiab chromatic tshuaj nyob rau hauv dej phwj tuaj tsim flocculents. Raws li lub sijhawm dhau mus, cov flocs maj mam nce thiab nyob rau hauv qab ntawm cov dej phwj tuaj.

4. Lim thiab sedimentation: Tom qab ib lub sij hawm ntawm sedimentation, cov flocculants nyob rau hauv cov dej phwj yuav maj mam nyob rau hauv qab los ua sludge. Tom qab ntawd, sludge tuaj yeem raug cais tawm ntawm cov dej huv los ntawm kev pom lossis centrifugation kom ua tiav lub hom phiaj ntawm cov dej phwj tuaj.
