Zinthu Zomwe Zimakhudza Kugwira Ntchito kwa Flocculant Pochiza Madzi Otayira

Pakukonza madzi otayidwa, pH ndi chinthu chofunikira chomwe chimakhudza mwachindunji magwiridwe antchito aFlocculantsNkhaniyi ikufotokoza momwe pH, alkalinity, kutentha, kukula kwa tinthu tating'onoting'ono tosayera, ndi mtundu wa flocculant pa mphamvu ya flocculation.

Zotsatira za pH

PH ya madzi otayira imagwirizana kwambiri ndi kusankha, mlingo, ndi mphamvu ya coagulation-sedimentation ya flocculants. Kafukufuku akusonyeza kuti pH ikakhala pansi pa 4, mphamvu ya coagulation imakhala yotsika kwambiri. Izi zitha kukhala chifukwa cha pH yochepa yomwe imapangitsa kuti tinthu ta colloidal tikhazikike m'madzi otayira, zomwe zimapangitsa kuti zikhale zovuta kuti flocculants iwambane bwino. Pamene pH ili pakati pa 6.5 ndi 7.5, mphamvu ya coagulation imakula kwambiri chifukwa kusakhazikika kwa tinthu ta colloidal mu pH iyi kumawonjezera mphamvu ya flocculants. Komabe, pamene pH ipitirira 8, mphamvu ya coagulation imachepa kwambiri, mwina chifukwa chakuti pH yapamwamba imasintha bwino ma ion m'madzi otayira, zomwe zimakhudza kwambiri flocculants.

Ngati pH ili yotsika kwambiri, PAC singathe kupanga ma floc bwino, ndipo magulu a anionic a APAM amachepetsedwa mphamvu, zomwe zimapangitsa kuti isagwire ntchito. Ngati pH ili yokwera kwambiri, PAC imagwa mofulumira kwambiri, zomwe zimapangitsa kuti pakhale ntchito yoipa, ndipo CPAM imakhala ndi vuto la hydrolysis ndipo sigwira ntchito bwino.

Udindo wa Alkalinity

Kuchuluka kwa madzi m'madzi otayira kumachepetsa pH. Ngati kuchuluka kwa madzi m'madzi otayira sikukwanira, nthawi zambiri pamafunika kuwonjezera mankhwala monga laimu kuti pH ikhale yokhazikika zomwe zimapangitsa kuti PAC isamayende bwino. Mosiyana ndi zimenezi, pamene pH ya madzi ili yokwera kwambiri, ma acid angafunike kuwonjezeredwa kuti pH ichepetsedwe kukhala yosalowerera, kuonetsetsa kuti ma flocculant akugwira ntchito bwino.

Zotsatira za Kutentha

Kutentha kwa madzi onyansa ndi chinthu chofunikira kwambiri chomwe chimapangitsa kuti flocculation igwire bwino ntchito. Pa kutentha kochepa, madzi onyansa amakhala ndi kukhuthala kwakukulu, zomwe zimachepetsa kuchuluka kwa kugundana pakati pa tinthu ta colloidal ndi zinyalala m'madzi, zomwe zimalepheretsa kuti flocculants isagwirizane. Chifukwa chake, ngakhale kuti kuchuluka kwa flocculants kumawonjezeka, flocculation imakhalabe yocheperako, zomwe zimapangitsa kuti mapangidwe osasunthika ndi tinthu tating'onoting'ono tomwe timavuta kuchotsa pa kutentha kochepa.

Mphamvu ya Kukula kwa Tinthu Tosayera

Kukula ndi kufalikira kwa tinthu tating'onoting'ono tosayera m'madzi otayira kumakhudzanso kwambiri momwe tinthu tating'onoting'ono tosayera timagwirira ntchito. Tinthu tating'onoting'ono tosafanana kapena tochepa kwambiri tingayambitse kuti tinthu tating'onoting'ono tosayera tisagwire ntchito bwino chifukwa tinthu tating'onoting'ono tosayera nthawi zambiri timakhala tovuta kusonkhanitsa bwino kudzera mu ma flocculant. Zikatero, kusungunuka kwa reflux kapena kuwonjezera kuchuluka koyenera kwa flocculant kungathandize kuti flocculant igwire ntchito bwino.

Kusankha Mitundu ya Flocculant

Kusankha mtundu woyenera wa flocculant ndikofunikira kwambiri kuti ntchito yokonza madzi otayidwa ikhale yothandiza. Mitundu yosiyanasiyana ya flocculant, monga inorganic flocculants, polymer flocculants, ndi activated silica gel, ili ndi ubwino wake m'mikhalidwe yosiyanasiyana. Mwachitsanzo, pamene zinthu zolimba zomwe zimapachikidwa m'madzi otayidwa zili mu mawonekedwe a colloidal, inorganic flocculants nthawi zambiri zimakhala zothandiza kwambiri. Pochita ndi tinthu tating'onoting'ono tomwe timayimitsidwa, kuwonjezera ma polymer flocculants kapena activated silica gel ngati coagulants kungakhale kofunikira. Nthawi zambiri, kugwiritsa ntchito pamodzi kwa inorganic ndi polymer flocculants kumatha kusintha kwambiri mphamvu ya flocculant ndikukulitsa kuchuluka kwa ntchito.

Zinthu monga pH, alkalinity, kutentha, kukula kwa tinthu tating'onoting'ono ta madzi onyansa, ndi mtundu wa flocculant zimakhudza kugwira ntchito kwa flocculant pochiza madzi onyansa. Kumvetsetsa bwino ndi kuwongolera zinthuzi ndikofunikira kwambiri pakukweza kugwira ntchito bwino kwa mankhwala onyansa. Ndife ogulitsa anu odalirika a mankhwala osungunuka, okhala ndi mitundu yambiri ya flocculant, kuphatikiza PAM, PAC, ndi zina zotero. Pa tsamba lathu lovomerezeka mutha kufufuza mosavuta zinthu zathu zosiyanasiyana. Ngati muli ndi mafunso kapena mukufuna thandizo, chonde musazengereze kulumikizana nafe!
