Qhov sib txawv thiab kev sib txuas ntawm PAC thiab PAM
PAC thiab PAM feem ntau hais ua ke. Dab tsi yog qhov sib txawv thiab kev sib txuas ntawm lawv?
PAC yog polyaluminium chloride, tseem hu ua dej purifier. Nws yog flocculant thiab coagulant rau kev kho dej phwj. Nws yog dav siv hauv kev kho dej phwj tuaj. Cov nyhuv kho tau zoo, kev ua haujlwm yooj yim, tus nqi qis nyiaj txiag. Raws li kev ntsuas ntsuas tau muab faib ua qib dej haus, qib kev lag luam, cov ntsiab lus tseem ceeb ntawm aluminium oxide (AL2O3), feem ntau ntawm 22 feem pua -31 feem pua. Raws li cov txheej txheem tsim khoom, nws tuaj yeem muab faib ua nruas ziab thiab tshuaj tsuag kom qhuav, uas muaj lawv tus kheej cov yam ntxwv thiab cov teebmeem hauv kev kho dej phwj sib txawv.
PAM yog polyacrylamide, yog tam sim no siv ntau tshaj plaws nyob rau hauv Suav teb, qhov zoo tshaj plaws kev kho mob nyhuv ntawm dej kho flocculant. Polyacrylamide yog linear polymer inorganic flocculant, raws li hom ionic tuaj yeem muab faib ua anionic, non-ionic, cationic, raws li kev ntsuas ntsuas tau muab faib ua qhov hnyav molecular 8-22 lab, ionic degree 10-60. Ntau hom ionic thiab molecular hnyav, ionic degree, nyob rau hauv ntau qhov chaw muaj daim ntawv thov zoo.
PAC thiab PAM yog tib yam dej kho flocculant, nyob rau hauv kev kho dej phwj tom qab nws dissolution thiab dej impurities tshem tawm cov teeb meem, tsim colloidal floc. Los ntawm kev nplawm, ua cov paj loj thiab tuab vanadium, thiab flocculation nag lossis daus. PAC thiab PAM yuav siv ua ke hauv kev kho dej phwj tuaj. Kev sib xyaw ua ke ntawm ob tsis tuaj yeem ua tiav cov txiaj ntsig zoo tshaj plaws. Nyob rau tib lub sijhawm, qhov ntau npaum li cas ntawm ob tus neeg sawv cev yuav raug txo, thiab tus nqi ntawm cov dej phwj tuaj yuav raug txo, thiab cov nqi kev lag luam yuav raug txo kom tsawg.
Qhov sib txawv ntawm PAC thiab PAM yog tias polyaluminium chloride yog coagulant, uas ua haujlwm zoo li tus choj hauv kev kho dej phwj tuaj thiab nyiam flocculation rau ib leeg. Tab sis polyacrylamide belongs rau cov polymer inorganic flocculant, nyob rau hauv dej phwj kho mob zoo molecular saw cov tshuaj tiv thaiv nrog dej phwj tuaj, tsim colloidal floc thiaj li mus cuag tau zoo tshaj plaws.
