Kev kho dej phwj tuaj Aluminium Sulphate

Kev kho dej phwj tuaj aluminium sulfate yog ib qho inorganic compound nrog cov tshuaj formula Al2 (SO4) 3. Nws yog ib tug dav siv synergistic precipitant thiab flocculant. Kev kho dej phwj tuaj aluminium sulfate yog cov hmoov dawb uas zoo li cov khoom amorphous lossis thaiv, yooj yim soluble hauv dej, thiab muaj zog acidity.

Hauv kev kho dej phwj tuaj, aluminium sulfate yog ib qho kev siv tshuaj kho mob, feem ntau yog siv los ua kom cov coagulation ntawm cov khib nyiab tshem tawm mus rau hauv cov khoom loj, yog li ua kom yooj yim rau sedimentation lossis pom, thiab ua tiav lub hom phiaj ntawm kev tshem tawm cov pa phem. Tsis tas li ntawd, kev kho dej phwj tuaj aluminium sulphate tuaj yeem cuam tshuam nrog lwm cov pa phem los tsim cov dej khib nyiab thaum kho dej khib nyiab, ua lub luag haujlwm tseem ceeb hauv kev tswj dej kom zoo. Lub caij no, kev kho dej phwj tuaj aluminium sulphate kuj tuaj yeem ua tus neeg sawv cev denitrification thiab dephosphorization, txo cov ntsiab lus ntawm cov as-ham xws li nitrogen thiab phosphorus.

Kev kho dej phwj tuaj aluminium sulfate tuaj yeem txo cov alkalinity ntawm cov dej khib nyiab, txo cov kab mob loj hlob hauv cov dej khib nyiab, tiv thaiv corrosion ntawm cov dej khib nyiab, txo cov viscosity ntawm cov dej khib nyiab, inhibit sedimentation, thiab tiv thaiv cov volatilization ntawm cov khoom phem hauv cov dej khib nyiab.

Nrog rau txoj kev loj hlob ntawm industrialization thiab urbanization, kev tso tawm ntawm cov kav dej phwj hauv tsev thiab cov dej khib nyiab hauv kev lag luam tseem nce ntxiv, thiab kev kho dej phwj tau dhau los ua qhov tseem ceeb hauv kev tiv thaiv ib puag ncig. Kev kho dej phwj tuaj aluminium sulfate tuaj yeem cuam tshuam nrog cov khoom tsis zoo xws li tshem tawm cov khib nyiab, cov teeb meem organic, thiab cov hlau hnyav hauv cov dej khib nyiab los tsim cov flocculents, yog li ua tiav lub hom phiaj ntawm kev tshem tawm impurities. Nyob rau tib lub sijhawm, Kev kho dej phwj tuaj aluminium sulfate tuaj yeem tswj hwm tus nqi pH thiab yaj cov pa oxygen ntawm cov dej, uas yuav pab txhim kho kev ua haujlwm ntawm cov dej phwj tuaj.
