Momwe mungasankhire flocculant yoyenera kwa inu poyeretsa madzi akumwa

Pokonza madzi otayidwa, amafunika kudutsa njira zingapo zogwirira ntchito, ndipo atayesedwa kuti akwaniritse muyezo wotulutsira madzi, amatulutsidwa. Mu ndondomekozi, flocculant imagwira ntchito yofunika kwambiri.Flocculantimatha kusuntha zinthu zomwe zapachikidwa m'madzi. Kukhazikika, zomwe zimapangitsa kuti zikhale zosavuta kusefa. Mitundu ya zinthu zopukutira nayonso ndi yolemera kwambiri. Momwe mungasankhire flocculant yomwe ikuyenererani ndiyofunikanso komanso yofunika. Ponena za kusankha zinthu zopukutira, opanga PAM ndi PAC ali ndi malingaliro otsatirawa:

Momwe mungasankhire flocculant pokonza madzi otayidwa iyenera kusankhidwa malinga ndi makhalidwe a madzi otayidwa mumakampani enaake. Nthawi yomweyo, zimatengera komwe flocculant imawonjezeredwa komanso zomwe imagwiritsidwa ntchito. Nthawi zambiri, posankha flocculant yopanda organic, kapangidwe ka madzi otayidwa kayenera kuganiziridwa, kenako sankhani yoyenera (mchere wachitsulo, mchere wa aluminiyamu kapena mchere wachitsulo-aluminium, mchere wa silicon-aluminium, mchere wa silicon-ferric, ndi zina zotero); ma flocculant a polymer osapangidwa ndi organic akuphatikizapo:polyaluminum chloride (PAC), polyaluminium sulfate (PAS), polyaluminum sulfochloride (PACSndisulfate ya polyferric (PFS), ndi zina zotero. Pakati pawo, PAC ndi PAS zomwe zimayimira bwino zimakhala ndi mawonekedwe osinthika bwino ndi kusintha kwa ubwino wa madzi omwe amathiridwa ndi mankhwala osaphika ochizira madzi, mphamvu yabwino yotsekereza ndi kuyeretsa, komanso mtengo wotsika wa mankhwala.

Posankha flocculant yachilengedwe (monga:polyacrylamide PAM), makamaka zimatengera ngati anionic polyacrylamide, cationic polyacrylamide kapena nonionic polyacrylamide zimagwiritsidwa ntchito. Anionic polyacrylamide zimadalira kuchuluka kwa hydrolysis. Kusankha ma cations nthawi zambiri kumagwiritsidwa ntchito pochotsa madzi m'matope. Kusankha cationic polyacrylamide ndikofunikira kwambiri. Malo oyeretsera zinyalala mumzinda nthawi zambiri amagwiritsa ntchito polyacrylamide yapakati-yamphamvu ya cationic. Ma cations ofooka nthawi zambiri amagwiritsidwa ntchito pochotsa madzi m'matope m'mafakitale opanga mapepala ndi kusindikiza ndi kupaka utoto, ndipo madzi otayira mankhwala nthawi zambiri amagwiritsidwa ntchito. Sankhani ma cations amphamvu ndi zina zotero. Mtundu uliwonse wa madzi otayira uli ndi mawonekedwe akeake. Non-ionic polyacrylamide imagwiritsidwa ntchito makamaka m'mikhalidwe yofooka ya asidi, ndipo non-ionic PAM imagwiritsidwa ntchito kwambiri m'mafakitale osindikizira ndi kupaka utoto.

Opereka mankhwala ochizira madziAmasonyeza kuti kusankha kwa ma flocculant onsewa kuyenera kutsimikiziridwa malinga ndi mayesowo. Mu mayesowo, dziwani kuchuluka kwa mlingo woyerekeza, onani liwiro la flocculation ndi sedimentation, werengerani mtengo wa chithandizo, ndikusankha wothandizira flocculation wotsika mtengo komanso woyenera.
