Tus txheej txheem tseem ceeb hauv kev kho dej kom huv yog qhov sib xyaw thiab kev daws teeb meem ntawm cov khib nyiab, cov txheej txheem uas nyob ntawm cov tshuaj hu uaFlocculantsCov. Hauv no, cov polymers ua lub luag haujlwm tseem ceeb, yog li Pam, tsab cai lij choj Flocculants, kev siv flocculants hauv kev kho kom dej huv, thiab cov haujlwm tom qab lawv.
Dab tsi yog cov nquag sivpolymer flocculants?
Feem ntau siv polymer flocculants muaj cationic polymers, anionic polymers thiab nonionic polymers. Cov polymers no tuaj yeem tau los ntawm cov hluavtaws hluavtaws sib txawv thiab muaj cov qauv sau sib txawv thiab cov ceg ntoo. Hauv kev siv cov kev siv, nws yog ib qho tsim nyog los xaiv tsim nyog polymer flocculants raws li cov xwm txheej tshwj xeeb kom tau txais kev kho mob zoo tshaj plaws. Pam, Polydadmac, yog siv dav hauv kev kho kom muaj kev kho dej khib nyiab. Polyacrylamide yog cov feem ntau siv cov flocculant nyob hauv lub ntiaj teb. Cov khoom siv hluav taws xob-solomle dej yog cov khoom siv tsim kho thiab cov khoom siv sib txawv, thiab lwm yam hauv cov dej sib txawv, thiab cov dej roj hmab nyoos Lub cev qhuav dej, daim ntawv kev lag luam thiab luam ntawv thiab cuam tshuam kev lag luam.
Kev siv ntawmFlocculants hauv kev kho kom zoo
Lub hom phiaj tseem ceeb ntawm kev kho dej kom tshem tawm cov paug tsis xws li cov paug tsis xws li cov khoom siv hauv cov dej organic thiab colloidal hais los ntawm cov dej txhawm rau txhim kho cov dej zoo. Hauv cov txheej txheem no, flocculants ua si lub luag haujlwm tseem ceeb. Los ntawm kev siv flocculants, me me iab nyob rau hauv dej tuaj yeem ua rau agglomerate rau hauv cov flocs loj, uas tuaj yeem muab tau yooj yim dua los ntawm sedimentation lossis kev lim dej. Qhov no tsis tuaj yeem txhim kho cov dej kom zoo, tab sis kuj txhim kho kev ua haujlwm zoo thiab txo tus nqi kho.
Vim li cas cov polymers tuaj yeem ua cov flocculants?
Polymbers tuaj yeem siv ua flocculant tsuas yog vim lawv cov qauv siab molecular thiab ntau tus qauv. Cov khoom no tso cai rau cov polymer rau Adsorb zoo dua rau qhov teeb meem, tsim cov flocs loj uas tuaj yeem daws tau sai. Ib qho ntxiv, cov polymers tuaj yeem tshem tawm cov tshuab hluav taws xob nruab nrab ntawm cov me me los ntawm kev txheeb xyuas kev neutralization, tso cai rau kev mus kom ze thiab agglomerate ua ke.
Lub tshuab ntawm kev ua ntawm cov polymers hauv kev kho kom zoo
Lub tshuab ntawm kev ua ntawm cov polymbers li flocculants tuaj yeem faib ua peb qib: kev faib nruab nrab, Bridging Flocculation thiab nee ntes. Ua ntej, lub polymer tshem tawm cov electrostatic rov qab los ntawm kev them nqi los ntawm kev kho mob neutralization, cia cov khoom kom mus kom ze. Cov neeg polymer ces txuas cov lus ua ke los tsim cov flocs loj dua los ntawm cov bridging flocculation. Thaum kawg, cov flocs tau txuas ntxiv txuas ntxiv thiab hais hauv dej los ntawm kev cheb cov nets.
Yam cuam tshuam rau kev ua haujlwm ntawm cov polymers hauv kev kho kom huv
Muaj ntau ntau yam uas cuam tshuam rau kev ua haujlwm ntawm cov dej polymer ntawm cov khoom lim dej, noj tshuaj polymer, xem, thiab ntau dua yog ib qho tseem ceeb tshaj plaws. Ntau hom polymers muaj cov nqi sib txawv thiab cov khoom hnyav molecular, yog li nws yog ib qho tsim nyog los xaiv cov khoom siv kom tsim nyog polymer kom ua tiav cov nyhuv zoo tshaj plaws. Ib qho ntxiv, cov ntsiab lus xws li PH nqi, ntsuas kub, thiab stirring deve yuav cuam tshuam rau kev kho mob, thiab cov kev mob siab yuav tsum tau txiav txim siab los ntawm kev sim.
Polymers ua lub luag haujlwm tseem ceeb npaum li cov nplaim roj hauv kev kho kom huv. Kev nkag siab tob ntawm cov txheej txheem ntawm kev ua thiab cuam tshuam cov ntsiab lus ntawm polymers tuaj yeem muab cov txheej txheem kev ua haujlwm zoo thiab ua kom zoo dua kev kho mob. Yav tom ntej, nrog kev txhim kho txuas ntxiv ntawm kev tiv thaiv ib puag ncig thiab thev naus laus zis, nws ntseeg tau tias daim ntawv thov kev kho dej kom ntev dua thiab tob tob.
