Yuav ua li cas ib tug sai thiab meej xaiv qhov tsim nyog flocculant? Ua ntej kho cov dej khib nyiab, nws yog ib qho tseem ceeb uas yuav tsum xav txog hom dej khib nyiab kom ntseeg tau tias cov txheej txheem xaiv tau raug thiab ceev dua. Yog li, dab tsi yuav tsum tau xav txog thaum xaiv flocculant?
Sludge yog ib qho khoom siv los ntawm kev kho dej khib nyiab. Nws yog ib qho tseem ceeb kom nkag siab txog cov sludge qhov chaw, cov khoom, muaj pes tsawg leeg, thiab cov ntsiab lus ntawm cov khib nyiab. Raws li cov ntsiab lus tseem ceeb, sludge tuaj yeem faib ua cov organic lossis inorganic. Feem ntau,cationic flocculantsyog siv rau cov organic sludge, thaum anionic flocculants yog siv rau inorganic sludge.
Cationic flocculants feem ntau tsis tsim nyog rau kev siv nyob rau hauv cov xwm txheej alkaline, thaum anionic flocculants tsis tsim nyog rau cov mob acidic. Cov ntsiab lus siab dua hauv cov sludge feem ntau xav tau ntau npaum li cas ntawm flocculant.
Xaiv Flocculant Ionicity: Rau cov sludge xav tau dewatering, me me - cov kev sim ntsuas tuaj yeem ua los tshuaj xyuas cov flocculants nrog ntau qib ntawm ionicity. Qhov no pab txheeb xyuas cov khoom zoo tshaj plaws kom ua tiav cov txiaj ntsig zoo flocculation thaum txo qhov ntau npaum thiab txo cov nqi.
Cov yam tseem ceeb hauv kev xaiv ionicity muaj xws li: floc loj, floc zog, thiab cov ntsiab lus noo noo.
Flocculant Particle Loj: Yog tias cov khoom me me dhau lawm, cov dej ceev tsis cuam tshuam; Yog tias loj dhau lawm, lawv yuav tsis khi dej txaus lossis txo cov sludge ntim tau zoo. Qhov loj me tuaj yeem hloov kho los ntawm kev xaiv flocculant nrog qhov tsim nyog qhov hnyav.
Flocculation Strength: Flocs yuav tsum nyob ruaj khov thiab tsis sib cais nyob rau hauv shear quab yuam. Ua kom cov flocculant qhov hnyav molecular los yog xaiv cov qauv molecular tsim nyog pab txhim kho kev ruaj ntseg.
Kev sib xyaw Flocculant nrog Sludge: Lub flocculant yuav tsum hnov qab tag nrho nrog cov sludge ntawm ib qho chaw tshwj xeeb hauv cov khoom siv dewatering kom induce flocculation. Yog li, cov tshuaj flocculant yuav tsum muaj qhov tsim nyog viscosity los xyuas kom meej sib xyaw nrog cov sludge muab cov cuab yeej uas twb muaj lawm. Kev sib xyaw ua ke yog qhov tseem ceeb rau kev ua tiav. Cov tshuaj viscosity nyob ntawm nws qhov hnyav molecular thiab concentration.
Flocculant Dissolution: Ib qho flocculant tuaj yeem ua tau zoo yog tias nws tau yaj tag nrho. Qee lub sij hawm, nws yog ib qho tsim nyog yuav tsum ua kom nrawm nrawm nrawm; Hauv cov xwm txheej zoo li no, nce qhov kev daws teeb meem yuav raug txiav txim siab.
