Hauv kev kho cov dej phwj tuaj ntawm papermaking, steel, metallurgy, ntxhia ua, tshuaj lom neeg kev lag luam, electroplating, slaughtering, nroog cov dej phwj thiab lwm yam lag luam, polyaluminium chloride thiab polyacrylamide feem ntau ntxiv kom ceev cov sedimentation tus nqi ntawm cov pa phem nyob rau hauv dej thaum lub sij hawm flocculation thiab sedimentation txheej txheem. . Thaum ntxiv cov tshuaj, polyaluminium chloride yog ntxiv ua ntej thiab tom qab ntawd polyacrylamide. Yog li vim li cas polyacrylamide yuav tsum tau siv nrog polyaluminium chloride? Vim li cas ntxiv polyaluminium chloride ua ntej thiab tom qab ntawd polyacrylamide?
Txhawm rau teb cov lus nug saum toj no, peb yuav tsum paub tias lub luag haujlwm ntawm polyaluminium chloride thiab polyacrylamide yog dab tsi.
Lub luag haujlwm ntawm polyaluminium chloride
1. Cov tshuaj aqueous ntawm polyaluminium chloride yog acidic, nrog tus nqi pH ntawm 3.5 thiab 5.0, uas tuaj yeem kho tus nqi pH ntawm cov dej zoo;
2. Tus nqi pH ntawm cov dej zoo siv rau polyaluminium chloride yog dav dua li ntawm polyacrylamide, ntawm 3 thiab 12;
3. Tom qab polyaluminium chloride los rau hauv cov dej phwj tuaj, nws yuav xub tsim ib pawg flocculent ntawm cov khoom me me;
4. Polyaluminium chloride yog coagulant, tseem hu ua coagulant pab, uas tuaj yeem ua lub luag haujlwm coagulant;
5. Polyaluminium chloride muaj peev xwm demulsification;
6. Thaum polyaluminium chloride siv ib leeg, flocs yuav tsim nyob rau hauv dej, tab sis cov flocs no tsis yooj yim los daws. Tom qab kev kho dej zoo, nws yog turbid heev thiab tsis tuaj yeem ua tiav cov txiaj ntsig ntawm kev nrawm nrawm thiab sedimentation.
Lub luag haujlwm ntawm polyacrylamide
1. Thaum siv polyacrylamide, pH ntau ntawm cov dej zoo nyob nruab nrab ntawm 6-9;
2. Thaum siv polyacrylamide ib leeg, cov nyiaj ntxiv yog loj thiab cov nyhuv tsis zoo. Nws yog ib qho tsim nyog yuav tau siv coagulant los kho tus nqi pH ua ntej.
Ua ke lub luag haujlwm thiab kev siv cov yam ntxwv ntawm Lvyuan's polyaluminium chloride thiab polyacrylamide, peb yuav nkag siab: nyob rau hauv lub flocculation thiab sedimentation theem ntawm cov dej phwj tuaj kho, polyaluminium chloride yuav tsum tau ntxiv ua ntej, thiab tom qab ntawd polyacrylamide.
Yog vim li cas yog: ntxiv polyaluminium chloride ua ntej tuaj yeem kho tus nqi pH ntawm cov dej zoo rau 6-9, uas yog tsim nyog rau kev siv polyacrylamide. Nyob rau tib lub sijhawm, polyaluminium chloride kuj tuaj yeem ua lub luag haujlwm coagulant, pab polyacrylamide kom nrawm sedimentation, ua kom cov dej ntshiab thiab cov sludge sinking.
Yog tias qhov kev txiav txim ntawm lawv qhov sib ntxiv yog thim rov qab, tsis yog tsuas yog cov txiaj ntsig kev kho mob yuav tsis ruaj khov, tab sis tus nqi ntawm polyaluminium chloride thiab polyacrylamide kuj yuav nce ntxiv.
Yog li ntawd, nyob rau hauv lub flocculation thiab sedimentation theem ntawm cov dej phwj tuaj kho, Lvyuan polyaluminium chloride PAC yuav tsum tau ntxiv ua ntej, thiab ces Lvyuan polyacrylamide PAM yuav tsum tau ntxiv.
