Hauv cov zej zog niaj hnub no, kev tiv thaiv thiab kev siv cov peev txheej dej tau dhau los ua qhov tseem ceeb ntawm kev saib xyuas thoob ntiaj teb.Nrog rau acceleration ntawm industrialization, dej tej chaw muaj kuab paug yog ua ntau thiab loj.Yuav ua li cas kho thiab ntxuav cov dej phwj kom zoo tau dhau los ua qhov teeb meem ceev uas yuav tsum tau daws.Hauv cov ntsiab lus no, PAM polymer flocculant tau los ua, nws tau yeej qhov kev pom zoo ntawm feem coob ntawm cov neeg siv nrog nws cov tshuaj lom neeg thiab cov txiaj ntsig kho dej zoo.
PAM, lub npe tag nrho ntawm polyacrylamide, yog ib qho polymer flocculant.Nws yog ib hom high polymer npaj los ntawm dawb radical polymerization ntawm acrylamide.Cov khoom muaj qhov hnyav molecular thiab tuaj yeem tsim cov khoom loj ntawm flocculants, uas muaj kev sib cais zoo thiab ruaj khov hauv dej, thiab tuaj yeem nqus tau zoo thiab tshem tawm cov teeb meem tshem tawm thiab cov kuab paug hauv dej.
Daim ntawv thov txheej txheem ntawm PAM polymer flocculant yog yooj yim heev.Ua ntej, cov tshuaj PAM yog ntxiv rau cov dej kom kho, thiab tom qab ntawd los ntawm kev nplawm los yog cov neeg kho tshuab nplawm, cov PAM thiab dej tau sib xyaw ua ke los tsim cov flocculent loj.Cov flocculents yuav nyob hauv dej, yog li ua tiav lub hom phiaj ntawm kev tshem tawm cov pa phem.Vim muaj tshuaj lom neeg ruaj khov ntawm cov khoom, cov dej kho tau tuaj yeem tso ncaj qha rau hauv ib puag ncig yam tsis muaj kev kho mob thib ob.
Qhov zoo ntawm cov khoom no tsis yog tsuas yog nws cov txiaj ntsig kev kho dej.Ua ntej, nws yog pheej yig dua los siv.Piv nrog rau cov kev kho dej ib txwm siv, xws li nag lossis daus, pom, thiab lwm yam, kev siv cov khoom siv tau yooj yim dua thiab kev lag luam ntau dua.Qhov thib ob, cov khoom lag luam muaj kev cuam tshuam tsawg dua rau cov dej zoo.Nws tsis hloov cov tshuaj lom neeg ntawm cov dej, yog li nws tsis ua rau muaj kuab paug thib ob rau ib puag ncig.Thaum kawg, kev kho cov nyhuv ntawm cov khoom yog qhov zoo, tuaj yeem tshem tawm cov teeb meem raug tshem tawm thiab yaj cov pa phem hauv dej, txhim kho qhov pom tseeb ntawm cov dej thiab qhov ntsuas qhov ntsuas.
Feem ntau, PAM polymer flocculant yog cov cuab yeej kho dej zoo thiab ib puag ncig zoo.Nws qhov kev tshwm sim tsis tsuas yog muab cov kev daws teeb meem tshiab los daws cov teeb meem ntawm cov dej qias neeg, tab sis kuj tseem muab kev txhawb zog rau kev txhawb nqa ntsuab thiab kev tswj xyuas dej kom ruaj khov.Nyob rau hauv lub neej yav tom ntej, nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho ntawm ib puag ncig kev paub, peb muaj laj thawj ntseeg tias cov khoom yuav ua lub luag haujlwm ntau dua hauv kev kho dej.
