Momwe mungasankhire flocculant yoyenera kwa inu pochiza madzi oyipa

Pokonzekera madzi onyansa, amayenera kudutsa njira zingapo zogwirira ntchito, ndipo atatha kuyesedwa kuti akwaniritse muyeso wotuluka, amachotsedwa.Panjira iyi, flocculant imagwira ntchito yofunika kwambiri.TheFlocculantakhoza flocculate inaimitsidwa nkhani yaing'ono mamolekyu m'madzi.Kukhazikika, kupangitsa kukhala kosavuta kusefa.Mitundu ya flocculants imakhalanso yolemera kwambiri.Momwe mungasankhire flocculant yomwe ikugwirizana ndi inu ndiyofunikanso komanso yofunika.Pankhani yosankhidwa kwa ma flocculants, opanga PAM ndi PAC ali ndi malingaliro awa:

Momwe mungasankhire flocculant mu mankhwala amadzi onyansa ayenera kusankhidwa molingana ndi makhalidwe a madzi onyansa mumakampani enaake.Panthawi imodzimodziyo, zimatengeranso komwe flocculant imawonjezeredwa ndi zomwe zimagwiritsidwa ntchito.Nthawi zambiri, posankha flocculant inorganic, zikuchokera madzi zinyalala ayenera kuganizira, ndiyeno kusankha yabwino (chitsulo mchere, zotayidwa mchere kapena chitsulo-zotayidwa mchere, pakachitsulo-zotayidwa mchere, pakachitsulo-zotayidwa mchere, etc.);Inorganic polymer flocculants ndi:polyaluminiyamu kloridi (PAC), polyaluminium sulphate (PAS), polyaluminium sulfochloride (Zotsatira PACS) ndipolyferric sulphate (PFS), etc. Pakati pawo, woimira kwambiri PAC ndi PAS ali ndi makhalidwe a kusinthika kwabwino kwa kusintha kwa madzi opangidwa ndi mankhwala opangira madzi opangira madzi, kugwirizanitsa bwino ndi kuyeretsa, komanso mtengo wotsika wa mankhwala.

Posankha organic flocculant (monga:polyacrylamide PAM), zimatengera ngati anionic polyacrylamide, cationic polyacrylamide kapena nonionic polyacrylamide imagwiritsidwa ntchito.Anionic polyacrylamides zachokera pa mlingo wa hydrolysis.Kusankhidwa kwa ma cations nthawi zambiri kumagwiritsidwa ntchito pochotsa madzi amatope.Kusankhidwa kwa cationic Polyacrylamide ndikofunikira kwambiri.Kumatauni zimbudzi mankhwala zomera zambiri ntchito sing'anga-amphamvu cationic Polyacrylamide.Ma cations ofooka nthawi zambiri amagwiritsidwa ntchito pochotsa madzi m'thupi popanga mapepala ndi kusindikiza ndi kupaka utoto, ndipo madzi otayira am'mankhwala amagwiritsidwa ntchito nthawi zambiri.Sankhani ma cations amphamvu ndi zina zotero.Mtundu uliwonse wa madzi oipa uli ndi makhalidwe ake.Non-ionic polyacrylamide amagwiritsidwa ntchito makamaka pansi pa mikhalidwe yofooka ya acidic, ndipo PAM yopanda ionic imagwiritsidwa ntchito kwambiri m'mafakitale osindikizira ndi utoto.

Opereka chithandizo chamadzianene kuti kusankha kwa ma flocculants onsewa kuyenera kutsimikiziridwa molingana ndi mayeso.M'mayeso, dziwani kuchuluka kwa dosing, yang'anani kuthamanga kwa flocculation ndi sedimentation, kuwerengera mtengo wamankhwala, ndikusankha wothandizila wachuma komanso wogwira ntchito.
