Kev siv PAM hauv kev txhim kho flocculation thiab sedimentation

Hauv cov txheej txheem kho dej phwj tuaj, kev sib xyaw ua ke thiab kev tso dej tawm yog ib feem tseem ceeb, uas muaj feem cuam tshuam ncaj qha rau qhov zoo ntawm cov dej khib nyiab thiab kev ua haujlwm ntawm tag nrho cov txheej txheem kho. Nrog rau kev nce qib tas mus li ntawm thev naus laus zis, polyacrylamide (PAM), ua cov khoom siv flocculant zoo, tau siv ntau dua hauv kev txhim kho flocculation thiab sedimentation. Tsab xov xwm no yuav tshawb nrhiav tob txog kev siv PAM hauv kev txhim kho flocculation thiab sedimentation, tshuaj xyuas nws cov txiaj ntsig thiab cov teeb meem, thiab xav kom koj nkag siab sai txog PAM.

Cov txiaj ntsig ntawm daim ntawv thov ntawm PAMnyob rau hauv kev txhim kho flocculation thiab sedimentation

Cov nyhuv flocculation sai: PAM molecules muaj cov yam ntxwv ntawm qhov hnyav molecular siab thiab qhov ceev ceev, uas tuaj yeem nqus cov khoom me me hauv dej sai sai thiab txhawb kev tsim cov flocs sai sai los ntawm kev txuas. Qhov no pab txo lub sijhawm settling thiab txhim kho kev ua haujlwm zoo.

Kev ua haujlwm ntawm cov dej phwj tuaj zoo dua: Los ntawm kev ntxiv PAM, qhov loj thiab qhov ceev ntawm cov flocs tau nce ntxiv, yog li txhim kho qhov sib cais ntawm lub tank dej phwj tuaj. Qhov no pab txo cov khoom khov uas raug tshem tawm hauv cov dej phwj tuaj thiab txhim kho qhov zoo ntawm cov dej phwj tuaj.

Haum rau ntau yam dej zoo: Cov hom thiab cov xwm txheej kho mob ntawm PAM tuaj yeem hloov kho raws li cov dej zoo sib txawv, ua rau nws tsim nyog rau kev kho dej nrog qhov turbidity siab, qhov turbidity tsawg thiab muaj ntau yam kuab paug.

Txo kev siv hluav taws xob: Kev siv PAM tuaj yeem ua rau lub sijhawm poob qis, yog li txo qhov kev siv hluav taws xob ntawm kev kho dej phwj tuaj. Qhov no yog qhov tseem ceeb heev rau kev txuag hluav taws xob thiab txo cov pa phem.

Txo cov sludge tsim tawm: Cov floc tsim los ntawm kev siv PAM muaj cov qauv nruj thiab cov dej tsawg, uas yog qhov zoo rau kev qhuav thiab pov tseg cov sludge, yog li txo cov nqi tsim tawm thiab pov tseg sludge.

Cov teeb meem thiab cov tswv yim teb ntawm PAM hauv kev txhim kho flocculation thiab sedimentation

Txawm hais tias PAM muaj cov txiaj ntsig zoo hauv kev txhim kho flocculation thiab sedimentation, kuj tseem muaj qee qhov teeb meem:

Kev Tswj Xyuas Qhov Tshuaj: Qhov tshuaj PAM yuav tsum tau hloov kho raws li qhov zoo ntawm cov dej tiag tiag. Kev noj tshuaj ntau dhau yuav ua rau cov flocs tawg ua tej daim me me. Yog li ntawd, kev tswj xyuas qhov tshuaj kom meej yog qhov tseem ceeb.

Teeb meem nrog cov monomers seem: Qee cov khoom PAM muaj cov monomers tsis tau polymerized, uas yuav muaj kev cuam tshuam rau ib puag ncig thiab tib neeg kev noj qab haus huv. Yog li ntawd, nws yog ib qho tseem ceeb kom xaiv cov khoom PAM nrog cov monomer seem tsawg thiab xyuas kom meej tias muaj kev tshem tawm cov monomers seem.

Kev Ua Haujlwm thiab Kev Txij Nkawm: Kev yaj thiab kev sib tov ntawm PAM xav tau cov khoom siv tshwj xeeb thiab cov xwm txheej ua haujlwm kom ntseeg tau tias nws tau sib npaug hauv dej. Yog li ntawd, muaj qhov xav tau los txhawb kev cob qhia tus neeg teb xov tooj thiab kev txij nkawm khoom siv.

Tus nqi thiab kev ruaj khov: Txawm hais tias PAM muaj qhov zoo hauv kev txhim kho flocculation thiab sedimentation, yog tias nws siv tsis raug, nws yuav siv tau ntau heev tab sis qhov cuam tshuam tsis yog raws li tus qauv, ua rau muaj kev pov tseg cov peev txheej thiab nce tus nqi. Yog li ntawd, yuav tsum tau them sai sai rau nws siv.
