Polyaluminium chlorideyog ib qho zoo heev flocculant, feem ntau siv hauv cov dej phwj hauv nroog thiab kev kho dej khib nyiab. Nws muaj cov yam ntxwv ntawm high efficiency thiab stability. Thaum peb tham txog PAC, ib qho ntawm cov cim qhia feem ntau hais yog qhov pib. Yog li dab tsi yog qhov yooj yim? Cov txiaj ntsig zoo li cas rau qhov zoo ntawm polyaluminium chloride? Kev nkag siab txog lub tswv yim no yuav muaj txiaj ntsig zoo rau kev xaiv ntawm polyaluminium chloride.
Dab tsi yog qhov yooj yim hauv polyaluminium chloride?
Hauv PAC, qhov tseem ceeb yog hais txog cov molar piv ntawm hydroxyl pawg rau txhuas ions. Nws feem ntau yog qhia raws li qhov yooj yim (B):
B = [OH-] / [Al3+]
Basicity yog ib qho tseem ceeb ntawm kev ua tau zoo ntawm polyaluminium chloride. Nws ncaj qha cuam tshuam cov nyhuv flocculation ntawm PAC.
Peb lub tuam txhab muab ntau hom PAC nrog lub hauv paus ntawm 40% txog 90%.
Lub mechanism ntawm kev cuam tshuam ntawm lub hauv paus ntawm polyaluminium chloride
Lub hauv paus cuam tshuam rau kev ua haujlwm ntawm PAC los ntawm kev cuam tshuam cov polymer morphology thiab kev faib tawm ntawm PAC. Alkalinity txiav txim siab qib ntawm polymerization ntawm txhuas hydroxyl complexes hauv PAC. Cov txheej txheem siab dua yog qhov tsim nyog rau kev tsim PAC nrog qib siab polymerization thiab txhim kho nws cov nyhuv flocculation. Thiab lub hauv paus tseem ceeb yuav cuam tshuam rau qhov zoo ntawm kev faib tawm ntawm PAC thiab nws lub peev xwm adsorption rau cov khoom tsis zoo.
Qhov cuam tshuam ntawm qhov pib ntawm PAC:
Kev tsim nyog hauv paus tuaj yeem ua kom zoo dua cov nyhuv flocculation ntawm polyaluminium chloride. Tsawg dhau lawm yuav ua rau tsis txaus hydrolysis ntawm PAC thiab txo cov nyhuv flocculation.
Lub hauv paus tseem yuav cuam tshuam qhov loj me, qhov ntom ntom thiab sedimentation tus nqi ntawm polyaluminium chloride condensed flocs. Kev tsim nyog hauv paus tuaj yeem ua qhov no zoo heev.
Yog li ntawd, nws yog ib qho tseem ceeb tshwj xeeb los xaiv tus qauv PAC raws li koj xav tau.
Peb tuaj yeem muab cov qauv PAC hauv qab no:
| Yam khoom | PAC-I | PAC-D | PAC-H | PAC-M | PAC-G |
| Qhov tshwm sim | Cov hmoov daj | Cov hmoov daj | Dawb hmoov | Mis hmoov | Milky Dawb hmoov |
| Cov ntsiab lus (%, Al2O3) | 29 ± 1 | 30 ± 1 | 30 ± 1 | 30 ± 1 | 30 ± 1 |
| Basicity (%) | 40–90 : kuv | 40–90 : kuv | 40–90 : kuv | 40–90 : kuv | 40–90 : kuv |
| Dej tsis sib haum (%) | 1.0 TSI MAX | 0.6 MAX | 0.6 MAX | 0.6 MAX | 0.6 MAX |
| pH | 3.0-5.0 Nws | 3.0-5.0 Nws | 3.0-5.0 Nws | 3.0-5.0 Nws | 3.0-5.0 Nws |
Peb ua nruj tswj hwm zoo ntawm peb cov koom haum polyaluminium chloride cov koom haum thiab tuaj yeem ua cov qauv kev pom zoo raws li cov neeg siv khoom sib txawv, muab cov neeg siv khoom zoo PAC uas ua tau raws li lawv cov kev xav tau. Peb pab pawg muag khoom muaj kev paub dhau los hauv kev xaiv cov khoom lag luam thiab tuaj yeem muab cov neeg siv khoom nrog cov lus qhia thiab cov qauv tsim nyog rau cov neeg siv khoom los ua cov kev sim beaker.
Yog tias koj tab tom nrhiav kev ntseeg siabPAC Supplierrau kev kho dej haus, kev kho dej khib nyiab lossis lwm yam kev siv, peb tuaj yeem muab kev cai PAC kom tau raws li koj xav tau. Tiv tauj peb tam sim no kom paub ntau ntxiv txog peb cov khoom lag luam PAC ua haujlwm siab thiab tau txais cov lus sib tw!
