In Industrial Wastewater Treatment, yuav muaj ntau cov khoom me me hauv cov dej khib nyiab.Txhawm rau tshem tawm cov khoom no thiab ua kom cov dej ntshiab thiab rov siv dua, nws yog qhov yuav tsum tau sivDej Tshuaj Additives -Flocculants (PAM) ua kom cov khoom tshem tawm impurities condense rau hauv cov molecules loj thiab nyob.
Cov colloid hais nyob rau hauv dej yog me me, thiab saum npoo yog hydrated thiab them kom lawv ruaj khov.Tom qab cov flocculant ntxiv rau hauv dej, nws yog hydrolyzed rau hauv ib qho kev them nyiaj colloid thiab nws cov ions nyob ib puag ncig los tsim micelles nrog cov qauv hluav taws xob ob txheej.
Cov txheej txheem ntawm kev nplawm sai sai tom qab txhaj tshuaj yog siv los txhawb txoj hauv kev thiab cov kev sib tsoo ntawm cov colloidal impurity hais hauv dej thiab cov micelles tsim los ntawm hydrolysis ntawm flocculant.Cov impurity hais nyob rau hauv cov dej ua ntej poob lawv stability nyob rau hauv qhov kev txiav txim ntawm lub flocculant, ces coagulate nrog ib leeg mus rau hauv loj hais, thiab ces nyob twj ywm los yog ntab nyob rau hauv lub sib cais chaw.
Cov khoom GT ntawm qhov nrawm gradient G tsim los ntawm nplawm thiab lub sijhawm nplawm T tuaj yeem sawv cev rau tag nrho cov khoom sib tsoo hauv tag nrho lub sijhawm cov tshuaj tiv thaiv, thiab cov nyhuv coagulation tuaj yeem tswj tau los ntawm kev hloov GT tus nqi.Feem ntau, tus nqi GT yog tswj los ntawm 104 thiab 105. Xav txog qhov cuam tshuam ntawm impurity particle concentration ntawm kev sib tsoo, GTC tus nqi tuaj yeem siv los ua tus tswj tsis ua haujlwm rau tus cwj pwm coagulation nyhuv, qhov C sawv cev rau qhov loj concentration ntawm impurity hais hauv cov dej phwj tuaj, thiab nws pom zoo tias tus nqi GTC nyob nruab nrab ntawm 100 los yog li ntawd.
Tus txheej txheem ntawm kev ua kom lub flocculant kom diffuse sai sai rau hauv dej thiab sib tov sib npaug nrog tag nrho cov dej khib nyiab yog hu ua kev sib tov.Cov impurity hais nyob rau hauv cov dej cuam tshuam nrog flocculant, thiab los ntawm cov txheej txheem xws li compression ntawm hluav taws xob ob txheej thiab hluav taws xob neutralization, kev ruaj ntseg yog ploj lossis txo, thiab cov txheej txheem ntawm kev tsim micro flocs hu ua coagulation.Cov txheej txheem ntawm agglomeration thiab tsim ntawm micro flocs loj hlob mus rau hauv loj flocs los ntawm mechanisms xws li adsorption bridging thiab sediment net capture nyob rau hauv lub agitation ntawm bridging tshuaj thiab dej ntws yog hu ua flocculation.Kev sib xyaw, coagulation thiab flocculation yog sau ua ke hu ua coagulation.Cov txheej txheem sib tov yog feem ntau ua tiav hauv lub tank sib tov, thiab coagulation thiab flocculation yog nqa tawm hauv cov tshuaj tiv thaiv tank.
