Lwm daim ntawv thov tseem ceeb ntawm polyamines yog nyob rau hauv lawv lub peev xwm los pab tshem tawm cov kab mob xws li cov hlau hnyav thiab cov pa phem.Los ntawm kev tsim cov complexes nrog cov kab mob no, polyamines pab txhawb lawv cov nag lossis daus, pab lawv sib cais los ntawm dej matrix.Qhov no yog tshwj xeeb tshaj yog zoo nyob rau hauv hais txog cov dej paug paug los ntawm industrial tso tawm los yog ua liaj ua teb runoff.

Kev cuam tshuam ib puag ncig ntawm polyamines hauv kev kho dej kuj tseem ceeb.Piv nrog rau cov tshuaj coagulants, polyamines feem ntau xav tau qis dua, ua rau txo cov tshuaj sludge ntau lawm.Qhov no tsis yog tsuas yog kho cov txheej txheem kho mob nkaus xwb tab sis kuj ua raws li kev txhawb nqa thoob ntiaj teb rau kev tswj hwm dej nyab xeeb thiab nyab xeeb.

Cov chaw kho dej thoob plaws ntiaj teb tau nce siv polyamines los ua ib feem ntawm lawv txoj kev kho mob vim lawv muaj ntau yam thiab ua haujlwm tau zoo.Cov kws tshawb fawb thiab cov kws tsim qauv txuas ntxiv tshawb nrhiav txoj hauv kev los txhim kho kev siv cov polyamines, kom ntseeg tau tias lawv daim ntawv thov hauv ntau hom kev kho dej.

Hauv kev xaus, PA tab tom hloov pauv kev kho dej los ntawm kev muab cov kev daws teeb meem zoo thiab ruaj khov kom ntseeg tau tias muaj dej huv thiab nyab xeeb.Raws li cov zej zog thiab kev lag luam cuam tshuam nrog cov teeb meem ntawm dej tsis txaus thiab muaj kuab paug, lub luag haujlwm ntawm polyamines hauv kev txhim kho cov txheej txheem kho dej tau dhau los ua qhov tseem ceeb.Kev txais yuav ntawm polyamines sawv cev yog ib kauj ruam tseem ceeb ntawm kev ua tiav lub neej yav tom ntej uas nkag mus rau cov dej huv yog qhov tseeb rau txhua tus.
