Ndi ma polima ati omwe amagwiritsidwa ntchito ngati Flocculants?

Gawo lofunika kwambiri pa njira yochizira madzi otayira ndi kugawanika ndi kukhazikika kwa zinthu zolimba zomwe zapachikidwa, njira yomwe imadalira kwambiri mankhwala otchedwa flocculants. Pankhaniyi, ma polima amachita gawo lofunikira, kotero PAM, polyamines. Nkhaniyi ifufuza za kufanana kwa zinthuzi.ma flocculant a polima, kugwiritsa ntchito ma polima ngati ma flocculant pochiza madzi akuda, ndi ntchito zomwe zili kumbuyo kwawo.

Kodi ma polymer flocculants omwe amagwiritsidwa ntchito kwambiri ndi ati?

Ma polymer flocculant omwe amagwiritsidwa ntchito kwambiri ndi monga ma cationic polymers, ma anionic polymers ndi ma nonionic polymers. Ma polymers awa amatha kupezeka pogwiritsa ntchito njira zosiyanasiyana zopangira ndipo ali ndi mapangidwe osiyanasiyana a cationic ndi nthambi. Mu ntchito zenizeni, ndikofunikira kusankha ma polymer flocculant oyenera malinga ndi momwe madzi amatayira amakhalira kuti apeze zotsatira zabwino kwambiri pakuchiza. PAM, polyDADMAC, imagwiritsidwa ntchito kwambiri pochiza madzi otayira m'mafakitale. Polyacrylamide ndiye flocculant yomwe imagwiritsidwa ntchito kwambiri padziko lonse lapansi. Ma polymers osungunuka m'madzi awa ndi opanga ndipo amatha kupangidwira ntchito zinazake ndi kulemera kosiyanasiyana kwa mamolekyulu, kukhuthala, madigiri osiyanasiyana a charge, mitundu yosiyanasiyana monga tinthu tating'onoting'ono, ma emulsions, ndi zina zotero. PolyDADMAC imagwiritsidwa ntchito kwambiri m'madzi apampopi, kugwedezeka kwa madzi osaphika, kusowa madzi m'madzi, makampani opanga mapepala ndi makampani osindikiza ndi kupaka utoto.

Kugwiritsa ntchito flocculants pochiza madzi akumwa

Cholinga chachikulu cha kuyeretsa madzi otayira ndi kuchotsa zinthu zoipitsa monga zinthu zolimba zomwe zimapachikidwa, zinthu zachilengedwe zosungunuka ndi tinthu ta colloidal m'madzi kuti madzi akhale abwino. Munjira imeneyi, zinthu zoyatsira madzi zimakhala ndi gawo lofunika kwambiri. Pogwiritsa ntchito zinthu zoyatsira madzi, tinthu tating'onoting'ono ndi zinthu za colloidal m'madzi zimatha kusonkhana kukhala ma floc akuluakulu, omwe amatha kuchotsedwa mosavuta ndi sedimentation kapena sefa. Izi sizingongowonjezera ubwino wa madzi, komanso zimathandizanso kuti madzi azigwira bwino ntchito komanso kuchepetsa ndalama zochizira.

Nchifukwa chiyani ma polima amatha kupanga ma flocculant?

Ma polima angagwiritsidwe ntchito ngati ma flocculant makamaka chifukwa cha kulemera kwawo kwakukulu kwa mamolekyulu ndi kapangidwe ka nthambi zambiri. Makhalidwe amenewa amalola polima kuti azitha kulowa bwino pa tinthu tating'onoting'ono, ndikupanga ma floc akuluakulu omwe amatha kukhazikika mwachangu. Kuphatikiza apo, ma polima amatha kuchotsa kugwedezeka kwamagetsi pakati pa tinthu tating'onoting'ono kudzera mu kuletsa mphamvu, zomwe zimathandiza kuti tinthu tating'onoting'ono tiyandikire ndikusonkhana pamodzi.

Njira yogwirira ntchito ya ma polima pochiza madzi otayira

Kagwiridwe ka ntchito ka ma polima monga ma flocculant kangagawidwe m'magawo atatu: kuletsa mphamvu ya magetsi, kuletsa kugwedezeka kwa madzi ndi kugwidwa kwa ukonde. Choyamba, polima imachotsa kugwedezeka kwa magetsi pakati pa tinthu kudzera mu kuletsa mphamvu ya magetsi, zomwe zimathandiza kuti tinthu tiyandikire. Kenako polimayo imalumikiza tinthu timeneti kuti tipange ma floc akuluakulu kudzera mu kusokoneza mphamvu ya magetsi. Pomaliza, ma floc amenewa amawonjezedwa pamodzi ndikukhazikika m'madzi kudzera mu ukonde wotambasula.

Zinthu zomwe zimakhudza magwiridwe antchito a ma polima pochiza madzi otayira

Pali zinthu zambiri zomwe zimakhudza momwe polima imagwirira ntchito bwino polima pochotsa madzi otayika, kuphatikizapo mtundu wa polima, mlingo, pH, kutentha, liwiro loyambitsa, ndi zina zotero. Pakati pa zinthu zimenezi, mtundu wa polima ndi mlingo wake ndi chimodzi mwa zinthu zofunika kwambiri. Mitundu yosiyanasiyana ya ma polima ili ndi mphamvu zosiyana zoyendetsera magetsi komanso kugawa kwa kulemera kwa mamolekyulu, choncho ndikofunikira kusankha mtundu woyenera wa polima ndi mlingo wa madzi otayika osiyanasiyana kuti mupeze zotsatira zabwino kwambiri zochizira. Kuphatikiza apo, zinthu monga pH, kutentha, ndi liwiro loyambitsa madzi zimakhudzanso momwe mankhwalawo amagwirira ntchito, ndipo mikhalidwe yabwino iyenera kudziwika kudzera mu zoyeserera.

Ma polima amagwira ntchito yofunika kwambiri ngati ma flocculant pa ntchito yokonza madzi akuda. Kumvetsetsa bwino momwe ma polima amagwirira ntchito komanso zinthu zomwe zimapangitsa kuti ma polima azigwira ntchito kungapereke chithandizo chofunikira cha chiphunzitso ndi chitsogozo chothandiza pakukonza njira zosamalira madzi akuda ndikukweza magwiridwe antchito a ntchito yokonza. M'tsogolomu, ndi kusintha kosalekeza kwa zofunikira zoteteza chilengedwe komanso kupita patsogolo kwa sayansi ndi ukadaulo, akukhulupirira kuti kugwiritsa ntchito ma polima pa ntchito yokonza madzi akuda kudzakhala kwakukulu komanso kozama.
