1.Qhov loj ntawm flocs: flocs me me dhau yuav cuam tshuam rau cov dej ntws ceev, thiab cov flocs loj dhau yuav khi dej ntau dua thiab txo qhov degree ntawm av nkos biscuit.Qhov loj ntawm floc tuaj yeem hloov kho los ntawm kev xaiv qhov hnyav molecular ntawm polyacrylamide.
2..Sludge yam ntxwv: Thawj qhov taw tes yog kom nkag siab qhov chaw, yam ntxwv, muaj pes tsawg leeg thiab kev faib ua feem ntawm sludge.Raws li cov khoom sib txawv, sludge tuaj yeem muab faib ua cov organic thiab inorganic sludge.Cationic polyacrylamide yog siv los kho cov organic sludge, thiab cov txheeb ze anionic polyacrylamide flocculant yog siv rau inorganic sludge.Anionic polyacrylamide yog siv thaum lub alkalinity muaj zog, thiab anionic polyacrylamide tsis haum rau muaj zog acidity.Cov ntsiab lus khoom Thaum cov sludge siab, tus nqi ntawm polyacrylamide feem ntau yog loj.
3.Flocculation zog: Flocculation yuav tsum nyob ruaj khov thiab tsis tawg nyob rau hauv qhov kev txiav txim ntawm shearing.Ua kom lub cev hnyav molecular ntawm polyacrylamide lossis xaiv cov qauv molecular tsim nyog yuav pab txhim kho kev ruaj ntseg ntawm flocs.
4.Ionicity ntawm polyacrylamide: Rau dewatered sludge, flocculants nrog ionicity sib txawv tuaj yeem xaiv los ntawm kev sim me me ua ntej, thiab qhov zoo tshaj plaws haum polyacrylamide tuaj yeem raug xaiv, kom cov nyhuv flocculant zoo tshaj plaws tuaj yeem tau txais, thiab kom txo tau qhov ntim thiab txuag. tus nqi.
5. Dissolution ntawm polyacrylamide: zoo dissolution muaj peev xwm muab tag nrho ua si rau cov nyhuv flocculation.Qee lub sij hawm nws yog ib qho tsim nyog yuav tsum ua kom nrawm nrawm, tom qab ntawd txiav txim siab nce qhov concentration ntawm cov tshuaj polyacrylamide.
Qhov tseeb, thaum kho cov dej phwj tuaj, rau qee cov dej phwj tuaj, kev siv ib qho flocculant tsis tuaj yeem ua tiav cov txiaj ntsig, thiab ob qho yuav tsum tau siv ua ke.Kev siv cov inorganic flocculant PAC thiab polyacrylamide composite flocculant los kho cov dej phwj tuaj yuav ua tau zoo dua.effect, tab sis xyuam xim rau qhov kev txiav txim thaum ntxiv potions, yog tias qhov kev txiav txim tsis raug, cov nyhuv yuav tsis tiav.
