Dab tsi yog qhov txawv ntawm coagulation thiab flocculation?

Coagulation thiab flocculation yog ob txoj hauv kev tseem ceeb siv hauv kev kho dej kom tshem tawm impurities thiab hais tawm ntawm dej.Thaum lawv muaj feem cuam tshuam thiab feem ntau siv ua ke, lawv ua haujlwm me ntsis txawv:

Coagulation:

Coagulation yog thawj kauj ruam hauv kev kho dej, qhov twg cov tshuaj coagulants ntxiv rau hauv dej.Cov coagulants feem ntau yogAluminium Sulfate(alum) thiab ferric chloride.Cov tshuaj no tau ntxiv los ua kom tsis muaj zog ntawm cov khoom siv hluav taws xob (colloids) uas muaj nyob hauv dej.

Cov coagulants ua haujlwm los ntawm neutralizing cov nqi hluav taws xob ntawm cov khoom no.Cov khoom hauv dej feem ntau muaj qhov tsis zoo, thiab cov coagulants qhia cov ions zoo.Qhov no neutralization txo cov electrostatic repulsion ntawm cov khoom, cia lawv los ze zog ua ke.

Raws li qhov tshwm sim ntawm coagulation, cov khoom me me pib ua ke, tsim cov khoom loj dua, hnyav dua hu ua flocs.Cov flocs no tseem tsis tau loj txaus los daws cov dej los ntawm lub ntiajteb txawj nqus ib leeg, tab sis lawv yooj yim dua los daws cov txheej txheem tom ntej.

Flocculation:

Flocculation ua raws li coagulation hauv cov txheej txheem kho dej.Nws yuav maj mam nplawm los yog ua rau cov dej agitating los txhawb cov me me floc particles kom sib tsoo thiab ua ke rau hauv loj thiab hnyav flocs.

Flocculation pab txhawb kev tsim cov loj, denser flocs uas muaj peev xwm daws tau dej ntau dua.Cov flocs loj no yooj yim dua los cais tawm ntawm cov dej kho.

Thaum lub sij hawm flocculation txheej txheem, ntxiv tshuaj hu ua flocculants yuav muab ntxiv los pab nyob rau hauv lub agglomeration ntawm flocs.Feem ntau flocculants muaj xws li polymers.

Hauv cov ntsiab lus, coagulation yog cov txheej txheem ntawm chemically destabilizing hais nyob rau hauv dej los ntawm neutralizing lawv cov nqi, thaum flocculation yog lub cev txheej txheem ntawm nqa cov no.destabilized hais ua ke los tsim flocs loj.Ua ke, coagulation thiab flocculation pab kom meej cov dej los ntawm kev ua kom yooj yim tshem tawm cov khoom tshem tawm thiab impurities los ntawm cov txheej txheem tom ntej xws li sedimentation thiab pom hauv cov nroj tsuag kho dej.
