Daim ntawv thov
Coagulant aluminium sulfate yog ib qho ntawm feem ntau siv, feem ntau yog siv rau kev ua kom huv ntawm cov dej haus thiab dej ua haujlwm. Lub tshuab yog: txhuas sulfate yaj hauv dej, hydrolyzed rau hauv cov ntsev ntsev thiab txhuas hydroxide muaj peev xwm ntes cov dej impurity hais.
Txoj kev siv
Vim tias cov khoom siv hydrolysis ntawm aluminium hydroxide aluminium sulfate tsuas yog nyob rau hauv pH tus nqi ntawm cov dej yog 6- 7, nws muaj solubility tsawg, thiaj li yuav ua rau cov khib nyiab tshem tawm hauv dej kom tau qhov zoo tshaj plaws flocculation sedimentation, pH tus nqi ntawm cov dej yuav tsum. khaws cia rau hauv qhov ntau ntawm 5.7-5.8. Thaum noj tshuaj ntawm txhuas sulfate flocculation kev kho mob, feem ntau 5- -50mg/L; yog tias txhawm rau tshem tawm, tus lej tuaj yeem ntxiv rau 90- -110mg / L. Yog tias nws yog siv rau decolorization, yuav tsum tau siv nrog txhuas sulfate thiab chloride, qhov zoo tshaj pH tus nqi yog 4.5- 5.5, siv tau 4-7.
