Ndi ma polima ati omwe amagwiritsidwa ntchito ngati Flocculants?

Gawo lofunikira kwambiri pakuyeretsa madzi akuwonongeka ndikuphatikizana ndi kukhazikika kwa zolimba zoyimitsidwa, njira yomwe imadalira kwambiri mankhwala otchedwa flocculants. Mu ichi, ma polima amagwira ntchito yofunika kwambiri, kotero PAM, polyamines.polymer flocculants, kugwiritsa ntchito ma polima monga flocculants mu kuthira madzi oipa, ndi ntchito kumbuyo kwawo.

Kodi ma polymer flocculants omwe amagwiritsidwa ntchito kwambiri ndi ati?

Ma flocculants omwe amagwiritsidwa ntchito kawirikawiri amaphatikizapo ma polima a cationic, ma polima anionic ndi ma polima a nonionic. Ma polima awa amatha kupezedwa ndi njira zosiyanasiyana zopangira ndipo amakhala ndi mitundu yosiyanasiyana ya cationic ndi nthambi. M'magwiritsidwe ntchito, ndikofunikira kusankha ma polymer flocculants oyenera malinga ndi momwe madzi akutayira amagwirira ntchito kuti mupeze chithandizo chabwino kwambiri. PAM, polyDADMAC, imagwiritsidwa ntchito kwambiri pochiza madzi onyansa m'mafakitale. Polyacrylamide ndiye flocculant yomwe imagwiritsidwa ntchito kwambiri padziko lonse lapansi. Ma polima osungunuka m'madzi awa ndi opangidwa ndipo amatha kupangidwa kuti azigwiritsidwa ntchito mwapadera ndi zolemera zosiyanasiyana zama cell, ma viscosities, madigiri osiyanasiyana amilandu, mitundu yosiyanasiyana monga tinthu tating'onoting'ono, emulsions, etc. kutaya madzi m'thupi, makampani opanga mapepala ndi makampani osindikizira ndi opaka utoto.

Kugwiritsa ntchito ma flocculants poyeretsa madzi oyipa

Cholinga chachikulu cha mankhwala amadzi otayira ndikuchotsa zowononga monga zolimba zoyimitsidwa, zinthu zosungunuka ndi colloidal particles m'madzi kuti madzi azikhala bwino. Mwanjira iyi, ma flocculants amagwira ntchito yofunika kwambiri. Pogwiritsa ntchito flocculants, ting'onoting'ono particles ndi colloidal zinthu m'madzi zingachititse agglomerate mu lalikulu flocs, amene mosavuta kuchotsedwa ndi sedimentation kapena kusefera. Izi sizingangowonjezera ubwino wa madzi, komanso kupititsa patsogolo chithandizo chamankhwala ndikuchepetsa mtengo wamankhwala.

Chifukwa chiyani ma polima amatha kupanga ma flocculants?

Ma polima amatha kugwiritsidwa ntchito ngati ma flocculants makamaka chifukwa cha kulemera kwawo kwa mamolekyulu komanso mawonekedwe anthambi yambiri. Zinthu izi zimalola polima kuti azitha kutsatsa bwino pa tinthu tating'onoting'ono, ndikupanga magulu akulu omwe amatha kukhazikika mwachangu. Komanso, ma polima angathe kuthetsa kunyansidwa electrostatic pakati particles kupyolera mlandu neutralization, kulola particles kuyandikira ndi agglomerate pamodzi.

Limagwirira ntchito ma polima mu madzi oipa mankhwala

Limagwirira ntchito ma polima monga flocculants akhoza kugawidwa mu masitepe atatu: mlandu neutralization, bridging flocculation ndi kulanda maukonde. Choyamba, ndi polima kumatha ndi electrostatic repulsion pakati particles kupyolera mlandu neutralization, kulola particles kuyandikira. Polima ndiye amalumikiza tinthu ting'onoting'ono pamodzi kuti tipange magulu akuluakulu kupyolera mu bridging flocculation. Potsirizira pake, magulu ameneŵa amasonkhanitsidwanso n’kukhazikika m’madzi chifukwa cha makoka akusesa.

Zinthu zomwe zimakhudza magwiridwe antchito a ma polima poyeretsa madzi oyipa

Pali zinthu zambiri zomwe zimakhudza mphamvu ya mankhwala a polima a madzi onyansa, kuphatikizapo mtundu wa polima, mlingo, pH mtengo, kutentha, kuthamanga kwachangu, etc. Pakati pawo, mtundu wa polima ndi mlingo ndi chimodzi mwa zinthu zofunika kwambiri. Mitundu yosiyanasiyana ya ma polima imakhala ndi katundu wosiyanasiyana komanso kugawa kwa maselo, chifukwa chake ndikofunikira kusankha mtundu woyenera wa polima ndi mlingo wamadzi otayira osiyanasiyana kuti mukwaniritse chithandizo chabwino kwambiri. Kuphatikiza apo, zinthu monga pH mtengo, kutentha, ndi kuthamanga kwamphamvu zidzakhudzanso magwiridwe antchito amankhwala, ndipo mikhalidwe yoyenera iyenera kutsimikiziridwa kudzera mukuyesera.

Ma polima amatenga gawo lofunikira ngati ma flocculants pakuyeretsa madzi oyipa. Kumvetsetsa mozama momwe ma polima amagwirira ntchito komanso momwe ma polima amathandizira atha kupereka chithandizo chofunikira chaukadaulo komanso chitsogozo chothandizira kukonza njira zoyeretsera madzi akuwonongeka ndikuwongolera bwino chithandizo. M'tsogolomu, ndikusintha kosalekeza kwa zofunikira zoteteza chilengedwe komanso kupita patsogolo kosalekeza kwa sayansi ndi ukadaulo, akukhulupirira kuti kugwiritsa ntchito ma polima poyeretsa madzi onyansa kudzakhala kozama komanso kozama.
