Cov cim qhia tseem ceeb uas yuav tsum tsom mus rau thaum yuav Polyaluminum Chloride yog dab tsi?

Thaum yuav khoomPolyaluminum Chloride(PAC), uas yog ib qho coagulant siv dav hauv cov txheej txheem kho dej, yuav tsum tau soj ntsuam ntau yam tseem ceeb kom ntseeg tau tias cov khoom ua tau raws li cov qauv tsim nyog thiab tsim nyog rau nws daim ntawv thov. Hauv qab no yog cov cim tseem ceeb uas yuav tsum tsom mus rau:

1. Cov Ntsiab Lus Aluminium

Cov khoom xyaw tseem ceeb hauv PAC yog txhuas. Qhov ua tau zoo ntawm PAC ua cov coagulant feem ntau nyob ntawm qhov concentration ntawm txhuas. Feem ntau, cov ntsiab lus txhuas hauv PAC yog qhia ua feem pua ​​ntawm Al2O3. PAC zoo feem ntau muaj ntawm 28% txog 30% Al2O3. Cov ntsiab lus txhuas yuav tsum txaus kom ntseeg tau tias cov coagulation zoo yam tsis siv ntau dhau, uas tuaj yeem ua rau tsis muaj txiaj ntsig zoo thiab muaj peev xwm cuam tshuam rau qhov zoo ntawm dej.

2. Qhov yooj yim

Qhov yooj yim yog qhov ntsuas ntawm qib hydrolysis ntawm cov txhuas hauv PAC thiab yog qhia ua feem pua. Nws qhia txog qhov piv ntawm hydroxide rau txhuas ions hauv cov kua. PAC nrog qhov yooj yim ntau ntawm 40% txog 90% feem ntau yog qhov zoo dua rau kev siv dej kho. Qhov yooj yim siab dua feem ntau txhais tau tias coagulation zoo dua tab sis yuav tsum tau sib npaug nrog cov kev cai tshwj xeeb ntawm cov txheej txheem kho dej kom tsis txhob kho ntau dhau lossis tsis kho txaus.

4. Qib Kev Ua Phem

Yuav tsum muaj cov khoom tsis huv xws li cov hlau hnyav (piv txwv li, txhuas, cadmium) tsawg kawg nkaus. Cov khoom tsis huv no tuaj yeem ua rau muaj kev pheej hmoo rau kev noj qab haus huv thiab cuam tshuam rau kev ua haujlwm ntawm PAC. PAC uas muaj kev ntshiab siab yuav muaj cov khoom tsis huv tsawg heev. Cov ntawv qhia tshwj xeeb uas cov chaw tsim khoom muab yuav tsum muaj cov ntaub ntawv hais txog qhov siab tshaj plaws uas tso cai rau cov khoom tsis huv no.

6. Hom (Khoom los yog Kua)

PACmuaj ob hom khoom khov (hmoov lossis granules) thiab kua. Kev xaiv ntawm cov khoom khov thiab kua nyob ntawm qhov xav tau tshwj xeeb ntawm lub chaw kho mob, suav nrog cov chaw khaws khoom, cov khoom siv dosing, thiab yooj yim ntawm kev tuav. Cov kua PAC feem ntau nyiam vim nws yooj yim siv thiab yaj sai, thaum cov khoom khov PAC yuav raug xaiv rau kev khaws cia ntev thiab kev thauj mus los. Txawm li cas los xij, lub sijhawm khaws cia ntawm cov kua luv luv, yog li nws tsis pom zoo kom yuav cov kua ncaj qha rau kev khaws cia. Nws raug pom zoo kom yuav cov khoom khov thiab ua nws koj tus kheej raws li qhov sib piv.

7. Lub Neej Txee thiab Kev Ruaj Ntseg

Qhov ruaj khov ntawm PAC dhau sijhawm cuam tshuam rau nws txoj kev ua tau zoo. PAC zoo yuav tsum muaj lub sijhawm khaws cia ruaj khov, tswj nws cov khoom thiab kev ua haujlwm tau zoo rau lub sijhawm ntev. Cov xwm txheej khaws cia, xws li qhov kub thiab txias thiab kev raug cua, tuaj yeem cuam tshuam rau qhov ruaj khov, yog li PAC yuav tsum khaws cia rau hauv qhov chaw txias thiab qhuav hauv cov thawv kaw kom khaws nws qhov zoo.

8. Kev Siv Nyiaj Zoo

Ntxiv rau qhov zoo ntawm cov khoom, nws tseem yog qhov tsim nyog los xav txog qhov tsim nyog ntawm kev yuav khoom. Piv cov nqi, ntim khoom, kev thauj mus los, thiab lwm yam ntawm cov neeg muag khoom sib txawv kom nrhiav tau cov khoom uas tsim nyog rau kev tsim nyog.

Hauv kev xaus, thaum yuav polyaluminum chloride, nws yog ib qho tseem ceeb uas yuav tsum xav txog cov ntsiab lus ntawm txhuas, qhov yooj yim, pH tus nqi, qib impurity, solubility, daim ntawv, lub sijhawm khaws cia, kev siv nyiaj tsim nyog, thiab kev ua raws li txoj cai. Cov ntsuas no ua ke txiav txim siab qhov tsim nyog thiab ua haujlwm tau zoo ntawm PAC rau ntau yam kev siv dej kho.
