Polyaluminium sulfate yog cov khoom sib xyaw polymer nrog cov qauv molecular loj thiab muaj peev xwm adsorption muaj zog, thiab nws cov dej ua kom huv si zoo dua li ntawm tag nrho cov tshuaj inorganic dej purifiers. Cov flocs tsim tom qab muab tso rau hauv cov dej nyoos yog qhov loj, cov sedimentation ceev ceev, kev ua haujlwm siab, thiab lub peev xwm lim tau zoo. Thiab nws muaj zog yoog tau rau txhua yam dej nyoos, thiab tsis tshua muaj txiaj ntsig rau pH tus nqi dej (PH tus nqi 4-11). Txawm hais tias qhov turbidity ntawm cov dej nyoos thiab qhov concentration ntawm cov pa phem hauv cov dej khib nyiab, nws cov nyhuv purification yog qhov zoo kawg li. Tsawg npaum li cas: tsawg corrosive rau cov khoom siv thiab cov kav dej, yooj yim rau kev khiav lag luam, me me, thiab cov nqi purification tsawg.
Khoom siv
1). Raws li kev siv nyiaj, cov tshuaj yuav tsum tau diluted 5-15 zaug.
2). Qhov ntau npaum li cas tuaj yeem txiav txim siab raws li qhov sib txawv turbidity ntawm cov dej nyoos. Feem ntau, cov turbidity (turbidity yog 100-500mg / L) dej, 10-20 kg ntawm cov khoom no yog siv ib txhiab tons, thiab cov turbidity muaj dej phwj yog tsis haus dej. Kev noj tshuaj kom tsim nyog muaj.
Cov ntaub ntawv tshwj xeeb solubility; polyaluminium sulfate yog insoluble nyob rau hauv ntshiab sulfuric acid (tsuas yog coexists), thiab yog yaj nyob rau hauv dej nrog sulfuric acid nyob rau hauv sulfuric acid tov, yog li solubility ntawm polyaluminium sulfate nyob rau hauv sulfuric acid yog solubility ntawm txhuas sulfate nyob rau hauv dej. Lub solubility ntawm txhuas sulfate yog 0 31.2 grams ntawm 10 degrees; 33.5 grams ntawm 10 degrees; 36.4 grams ntawm 20 degrees; 40.4 grams ntawm 30 degrees; 45.7 grams ntawm 40 degrees; 52.2 grams ntawm 50 degrees; 59.2 grams ntawm 60 degrees; 66.2 grams ntawm 70 degrees; 73,1 g; 86.8 grams ntawm 90 degrees; 89 grams ntawm 100 degrees. Polyaluminium sulfate yog siv dav siv hauv kev lag luam reagent uas feem ntau tsis meej pem nrog alum. Polyaluminium sulfate feem ntau yog siv los ua flocculant hauv kev ua kom huv ntawm cov dej haus thiab cov khoom siv dej phwj tuaj, nrog rau hauv kev lag luam ntawv. Nyob rau hauv tej yam ntuj tso, polyaluminium sulfate tsis tshua muaj nyob rau hauv daim ntawv ntawm anhydrous ntsev. Nws tsim ib tug series ntawm hydrates.
