Anionic Polymer Flocculants tuaj yeem kho cov khib nyiab los ntawm kev ua yeeb yam hauv ntxhia, yog li txo cov nqi kev kho dej rau kev lag luam. Tam sim no, feem ntau cov kev kho dej kom huv ntau tshaj plaws rau kev lag luam mining hauv Suav teb yog tus txheej txheem koom tes nrog kev ua yeeb yam, ua haujlwm rau cov pa roj teeb, thiab rov siv dua. Cov kev tshawb fawb txog kev sim ntawm cov chaw me me tau qhia tias txawm tias yog ib hom dej huv ntau ntxiv nyob ntawm tus neeg saib xyuas kev kho mob tau siv los yog siv tshuaj tiv thaiv tus neeg sawv cev.
Coagulation theem: feem ntau siv cov coagulants suav nrog polyaluminium chloride (PAC), polyfertric sulfate (PFS) thiab Alum. Nws raug nquahu kom xaiv cov khoom lag luam uas tsim nyog tshaj plaws los ntawm kev sim.
Flocculation Stage: Polyacrylamide nrawm nrawm ntawm tus nqi ntawm sedimentation ntawm cov nqi uas tsis raug. Txawm li cas los xij, cov pob zeb sib txawv muaj cov kev xav tau rau cov qib ntawm cov hydrolysis ntawm polyacrylamide. Nws yog ib qho tsim nyog los xaiv ib qho kev tsim nyog hydrolysis raws li qhov taw qhia ua ntej. Feem ntau, ib qho tswv yim ntawm 0.2 mg / l ntawm Pam yog txaus.
Adsorption theem: cov tshuaj ntawm cov hmoov ua haujlwm rau cov pa roj carbon tsawg tsawg dua li cov roj carbon granular. Vim tias hmoov ua haujlwm carbon ua haujlwm tau nkag mus rau hauv lub voj voog dej, hmoov txhuas feem ntau raug xaiv hauv cov khoom loj. Cov kev pom zoo tshaj plaws yog feem ntau ntawm 50 ~ 100 mg / l.
Tom qab tau txais txiaj ntsig zoo rau cov txiaj ntsig flocculation thiab kev ua yeeb yam thiab adsentation los ntawm cov pa roj carbon ntau, nws tuaj yeem raug rov qab siv yam tsis muaj kev cuam tshuam rau cov neeg tau txais txiaj ntsig.
Anionic Polyacrylamide yog ib txwm siv nyob rau hauv kev kho txheej txheej ua haujlwm ntawm cov ntxhia. Nws cov molecular hnyav tuaj yeem ncav cuag 6-18 lab. Nws nqus cov khib nyiab tshem tawm hauv cov dej los ntawm kev cuam tshuam hluav taws xob, kev tsim cov flocs loj dua thiab nrawm nrawm ntawm cov khoom kom raug hauv kev ncua ntawv.
Qhov taw qhia ntawm anionic polyacrylamide
| Kev tshwm sim | Dawb granules |
| Cov ntsiab lus nyuaj | Ntau dua los yog sib npaug rau 88% |
| Molecular hnyav | 6 lab - 20 lab |
| Kev Ua Haujlwm Hydrolysis | 10 - 35% |
| Lub sijhawm ua tiav | Tsawg dua los yog sib npaug rau 90 feeb |
| Tus ntxhiab | Tsw |
| Lom zem | Tsis -} toxic |
| Kev corrosiveness | Tsis - corrosive |
| Thaum tshav kub kub | Yooj yim decomposes thaum qhov kub tshaj 120 degree |
Polyacrylamub siv:
Ua ntej siv, polyacrylamide yuav tsum tau npaj rau hauv 0.1% rau 0.3% daws. Ua tiav kev sib cais yuav tsum tau nplawm ntawm chav tsev kub rau 40 feeb. Qhov npaj PAM kev daws yuav tsum tau siv tam sim ntawd thiab yuav tsum tsis txhob muab cia rau ncua sijhawm kom tsis txhob muaj kev tawm tsam.
Polyacrylamide Dosing Txoj Kev:
1. Lub ntiajteb tau nqus Dosing: Siv lub ntiajteb txawj nqus ntxiv rau tus neeg sawv cev mus rau cov dej phwj dej, tso cai rau cov dej ntws mus sib xyaw.
2. Kev siab: Siv cov twj tso kua mis kom ntxiv cov neeg sawv cev rau lub siab yeeb nkab.
Cim npe nrov: Anionic Polymer Flocculant tshuaj tua hmoov rau cov ntxhia ua hmoov, Suav anionic polymulrant tshuaj hmoov rau cov khoom siv ntxhia, cov chaw muag khoom
