Nrog rau kev nrawm ntawm kev lag luam, cov dej phwj tuaj tau dhau los ua qhov teeb meem loj hauv ntiaj teb kev tiv thaiv ib puag ncig. Lub hauv paus ntawm kev kho dej phwj yog nyob rau hauv kev xaiv thiab sivflocculantsnyob rau hauv cov txheej txheem purification. Nyob rau hauv xyoo tas los no, high-efficiency polyaluminum chloride (PAC), uas yog ib qho tseem ceeb flocculant, tau maj mam dhau los ua "lub hnub qub khoom" nyob rau hauv cov dej phwj kev lag luam vim nws cov kev ua tau zoo heev thiab dav daim ntawv thov prospects.
Polyaluminium chloride yog ib qho inorganic polymer compound nrog muaj zog flocculation nyhuv. Nws tau txais los ntawm cov tshuaj tiv thaiv polymerization ntawm aluminium chloride thiab aluminium hydroxide nyob rau hauv tej yam kev mob. Piv nrog rau cov tsoos txhuas ntsev flocculants (xws li txhuas sulfate, txhuas ntsev coagulant, thiab lwm yam), high-efficiency polyaluminum chloride muaj peev xwm ua kom muaj peev xwm tshem tawm cov pa phem, tshwj xeeb tshaj yog thaum muaj kev kub ntxhov thiab cov roj hnyav. Qhov kev ua tau zoo tshwj xeeb tshaj yog thaum nws los txog rau dej zoo. Nws tau siv dav hauv ntau qhov chaw xws li kev kho dej phwj hauv nroog, kev kho dej phwj tuaj, thiab kev kho dej phwj hauv tsev.
Qhov zoo ntawm high-efficiency polyaluminium chloride
1. Cov nyhuv flocculation yog qhov zoo kawg
High-efficiency polyaluminium chloride tuaj yeem tsim ntau cov nplua flocs hauv dej sai sai, yog li adsorbing tshem tawm cov khib nyiab, cov tshuaj colloidal thiab cov kab mob hauv dej. Nws tuaj yeem sai sai adsorb thiab tshem tawm cov khoom tshem tawm, roj, hnyav hlau ions thiab lwm yam khoom paug hauv dej. Tshwj xeeb tshaj yog thaum cuam tshuam nrog cov dej tsis zoo, cov nyhuv yog qhov zoo dua rau cov tshuaj txhuas ntsev flocculants. Hauv kev kho dej phwj tuaj, kev ua haujlwm siab ntawm polyaluminum chloride tuaj yeem ua rau kom nrawm nrawm ntawm cov dej khib nyiab hauv lub sijhawm luv luv, yog li txo qhov kev kho dej phwj tuaj.
2.Kev siv ntau yam
High-efficiency polyaluminium chloridetuaj yeem hloov mus rau ntau yam dej tsis zoo, suav nrog cov dej turbidity siab, siab oily dej phwj tuaj, cov dej uas muaj cov hlau hnyav, thiab cov dej tsis muaj dej tsis zoo, uas qhia tau tias muaj zog adaptability. Nws tuaj yeem tshem tawm cov khib nyiab feem ntau thiab cov pa phem hauv dej, thiab tuaj yeem siv dav hauv kev kho dej phwj hauv ntau qhov chaw xws li kev tswj hwm hauv nroog, kev lag luam, thiab kev tsuas. Piv txwv li, hauv kev kho cov dej phwj hauv tsev, cov dej khib nyiab khib nyiab, cov dej khib nyiab metallurgical, cov khoom noj khoom haus khib nyiab thiab lwm yam xwm txheej, kev ua haujlwm siab polyaluminum chloride tuaj yeem ua tiav cov txiaj ntsig zoo.
3. Tsawg npaum li cas, kev ua haujlwm siab thiab txuag hluav taws xob
High-efficiency polyaluminium chloride yog tsim los ua kom tau txais tsawg dua thiab cov nyhuv flocculation zoo dua. Qhov ntau npaum li cas rau qis-turbidity yog 25-40% ntawm txhuas sulfate, thiab qhov ntau npaum li cas rau high-turbidity yog 10-25% ntawm txhuas sulfate. Qhov no tsis tsuas yog txo tus nqi ntawm kev siv tshuaj, tab sis kuj txo qis kev siv hluav taws xob thiab sludge hauv cov txheej txheem dej phwj tuaj. Vim nws tsis tshua muaj aluminium residue, nws txo cov pa phem thib ob ntawm cov dej hauv lub cev thiab txo tus nqi tag nrho ntawm kev kho dej phwj tuaj. Yog li ntawd, nws tau dhau los ua ib qho cuab yeej tseem ceeb kom txuag tau cov nqi thiab txhim kho kev ua tau zoo hauv kev siv tswv yim.
4. Ib puag ncig tus phooj ywg
Kev siv cov khoom siv high-efficiency polyaluminium chloride muaj kev cuam tshuam tsawg dua ntawm ib puag ncig thiab tsis tshua muaj aluminium residue. Piv nrog rau lwm cov tshuaj flocculants, polyaluminium chloride muaj kev nyab xeeb dua thiab muaj kev cuam tshuam tsawg dua ntawm pH thiab TA ntawm cov dej ntws, yog li qhov kev thov rau cov tshuaj kho pH thiab TA raug txo. Tshwj xeeb tshaj yog nyob rau hauv loj-scale kev kho dej phwj thiab tej yaam num tiv thaiv ib puag ncig, nws tau dhau los ua ib tug greener thiab ntau environmentally friendly xaiv.
5. Haum rau qhov kub thiab txias thiab siab turbidity dej kho
Kev kho dej hauv lub caij kub qis yog ib qho kev sib tw. Tshwj xeeb tshaj yog nyob rau lub caij ntuj no txias, qhov ua tau zoo ntawm ntau cov tshuaj flocculants yuav raug txo kom tsawg. Txawm li cas los xij, kev ua haujlwm siab polyaluminum chloride tuaj yeem ua kom muaj kev ua haujlwm siab flocculation nyob rau hauv qhov kub thiab txias. Tsis tas li ntawd, thaum dej turbidity siab, PAC kuj qhia tau hais tias muaj zog ua lub peev xwm thiab tuaj yeem tshem tawm cov khoom uas raug tshem tawm thiab cov khoom colloidal hauv dej. Rau cov dej nrog cov roj hnyav hnyav, kev ua haujlwm siab polyaluminum chloride kuj muaj cov nyhuv degreasing zoo heev.
6. Hloov mus rau qhov sib txawv pH tus nqi
High-efficiency polyaluminium chloride muaj zog adaptability rau cov kev hloov hauv dej pH thiab tuaj yeem ua haujlwm zoo hauv ntau qhov pH. Feem ntau hais lus, PAC tuaj yeem tswj xyuas cov nyhuv flocculation zoo hauv dej nrog qis (acidic) lossis siab dua (alkaline) pH tus nqi, uas txuas ntxiv nthuav nws qhov kev siv tau raws li ntau yam dej zoo. 5.0-9.0 vs 5.5-7.5
7. Txhim kho sedimentation efficiency thiab txo sludge ntim
High-efficiency polyaluminium chloride pab ua kom lub zog ntawm cov khoom siv hauv cov kav dej phwj tuaj thiab txhim kho kev ua haujlwm ntawm lub tank sedimentation los ntawm kev txhim kho qhov ceev thiab kev sib haum xeeb ntawm flocs. Tsis tas li ntawd, vim muaj cov qib siab ntawm polymerization ntawm high-efficiency polyaluminum chloride, cov flocs tsim yog nruj dua thiab khom sai dua, yog li txo cov sludge tsim. Qhov no yog qhov tseem ceeb heev rau kev kho sludge tom ntej thiab pov tseg, thiab tuaj yeem txo tus nqi thiab nyuaj ntawm kev kho sludge.
Daim ntawv thov piv txwv ntawm high-efficiency polyaluminium chloride hauv kev kho dej khib nyiab
