Polyacrylamide (Pam)tuaj yeem ua ke nrog lwm cov flocculants, coagulant ID thiab lwm yam khoom kom ua tiav cov teebmeem zoo dua. Qhov kev siv sib xyaw ua ke no tuaj yeem ua tau raws li cov dej sib txawv thiab kev kho mob kom txhawb nqa cov nqi kho flocculation, txo qis kev txuag dej.
1. Thaum siv ua ke nrog inorganic flocculants
(1) Lub hauv paus ntsiab lus:
Polyacrylamide, raws li cov organic siab - cov roj av (xws li siv cov flocculant, thaum lwm yam), tuaj yeem siv tau ntawm lawv cov txiaj ntsig,Siv cov nyhuv synergistic, thiab txhim kho cov nyhuv flocculation.
(2) Daim ntawv thov:
Nyob rau hauv cov dej nyoos,Inorganic flocculants tuaj yeem ntxiv ua ntej, ua raws li los ntawm polyacrylamide.Los ntawm kev noj kom zoo dua ntawm lub ntev- Cov kab ntawm polyacrylamide, cov flocs flocculants tuaj yeem loj hlob ntxiv thiab ua kom nrawm dua. Polyacrylamide tseem tuaj yeem ntxiv ua ntej, ua raws li los ntawm inorganic flocculants, los tsim cov flocs loj dua thiab txhim kho cov kev kho mob.
(3) Zoo:
Nws tuaj yeem txo cov tshuaj ntawm flocculants, txhim kho kev kho dej kom zoo, txo cov khoom siv ntawm nplai, thiab kev tiv thaiv cov khoom siv ntawm cov khoom siv, thiab lwm yam.
2. Thaum siv ua ke nrog lwm cov organic flocculants
(1) txoj ntsiab cai:
Txawv ntau hom organic polymer flocculants, muaj anionic, tuaj yeem ua ke ntawm cov xwm txheej thiab lub hom phiaj ntawm cov dej khib nyiab kom ua tiav cov txiaj ntsig flocculation zoo tshaj plaws.
(2) Daim ntawv thov:
Piv txwv li, thaum kho cov dej khib nyiab nrog kev them nqi tsis zoo, thiab tom qab ntawd anionic polyacrylamide tuaj yeem raug ntxiv los txhawb qhov tsim thiab sedimentation ntawm flocs.
(3) Zoo:
Raws li cov hom phiaj sib txawv thiab kev kho mob, tsim nyog sib xyaw ntawm cov organic flocc
