Kev Kho Mob Wastewater - Flocculants (Pam)

Hauv kev siv dej khib nyiab, muaj qee qee qee zaum tsis zoo uas ua rau cov dej huab, uas ua rau cov neeg tsis yooj yim los ntxuav. Nws yog qhov yuav tsum tau siv cov flocculant kom ua kom dej ntshiab kom tau raws li cov qauv tso tawm. Rau cov flocculant, peb pom zooPolyacrylamide (Pam).

FlocculantRau Kev Kho Mob Khib

Polyacrylamide yog dej-soluble polymer. Nws cov molecular saw muaj cov pab pawg polar, uas tuaj yeem adsorb cov lus raug tshem tawm hauv kev daws teeb meem thiab agglomerate cov lus los tsim cov flocs loj dua. Cov flocs loj tuaj yeem ua kom nrawm nrawm ntawm cov nag lossis daus ntawm cov ntawv raug tshem tawm thiab ua kom nrawm ntawm cov nyhuv ntawm cov kuab qhia meej. Piv nrog kho kom zoo ib yam li kev kho kom huv, tshuaj lom neeg tshuaj khib nyiab yog qhov nyuaj heev. Hauv cov txheej txheem ntawm kev kho cov tshuaj lim dej lim dej, ntau yam chaw nyob xws li flocculants, coagulants, thiab decolorizers xav tau. Ntawm lawv, cov nquag siv flocculant yog noionic polyacrylamide.

Txoj kev txhim kho ntawm polyacrylamide

1. Lub polyacrylamide molecular saw muaj cov pab pawg polar, uas tuaj yeem nqus cov pawg neeg raug tshem tawm hauv dej thiab choj nruab nrab los tsim cov flocs loj dua.

2. Tsis yog-ionic polyacrylamide tuaj yeem nrawm rau cov dej nag tsis muaj zog los ntawm kev tsim cov kev qhia loj dua ntawm kev daws teeb meem thiab txhawb nqa cov nyhuv pom.

3. Ntawm tag nrho cov khoom noj flocculant, tsis muaj ionic polyacrylamide muaj cov txiaj ntsig zoo hauv kev kho acidic dej, thiab cov tshuaj lim dej feem ntau yog acidic. Yog li ntawd, tsis-ionic polyacrylamide muaj nws cov txiaj ntsig zoo hauvKev Kho Mob Tshuaj Tso Tshuaj.

4. Cov coagulant tuaj yeem siv ua ke nrog inorganic salts xws li polyaluminum, polyiron thiab lwm cov roj inoracculants, thiab cov nyhuv zoo dua. Nws yog qhov tseeb vim yog cov yam ntxwv ntawm cov tsis-ionic polyacrylamide uas nws tau pom tseeb zoo hauv kev kho tshuaj lom neeg quav tshuaj.

Peb muab cov txiaj ntsig zoo rau kev ua ntej ntawm lub hoobkas, kom koj tuaj yeem tau txais nqi sams-zoo tshaj plaws thiab kev txaus siab tom qab muag.
