Zomwe zimakhudza kugwiritsa ntchito ma flocculants pochiza zimbudzi

pH ya zimbudzi

Phindu la pH la zimbudzi limakhudza kwambiri zotsatira za flocculants.Phindu la pH la zimbudzi limagwirizana ndi kusankha kwa mitundu ya flocculant, mlingo wa flocculants ndi zotsatira za coagulation ndi sedimentation.Pamene mtengo wa pH uli<4, zotsatira za coagulation ndizochepa kwambiri.Pamene pH mtengo uli pakati pa 6.5 ndi 7.5, zotsatira za coagulation zimakhala bwino.Pambuyo pH mtengo>8, zotsatira za coagulation zimakhalanso zosauka kwambiri.

Kuchuluka kwa alkalinity m'chimbudzi kumakhala ndi vuto linalake pamtengo wa PH.Pamene alkalinity ya zimbudzi sikukwanira, laimu ndi mankhwala ena ayenera kuwonjezeredwa.Pamene pH mtengo wa madzi uli wokwera, m'pofunika kuwonjezera asidi kuti asinthe pH kuti asalowerere.Mosiyana ndi izi, ma polymer flocculants samakhudzidwa kwambiri ndi pH.

kutentha kwa chimbudzi

Kutentha kwa zimbudzi zingakhudze liwiro flocculation wa flocculant.Pamene zimbudzi ndi kutentha otsika, mamasukidwe akayendedwe a madzi ndi mkulu, ndipo chiwerengero cha kugunda pakati flocculant colloidal particles ndi zonyansa particles m'madzi yafupika, amene amalepheretsa n'zogwirizana adhesion wa flocs;choncho, ngakhale kuti mlingo wa flocculants ukuwonjezeka, mapangidwe a flocs Akadali pang'onopang'ono, ndipo ndi otayirira komanso opangidwa bwino, zomwe zimapangitsa kuti zikhale zovuta kuchotsa.

zonyansa m'zimbudzi

The m'goli kukula kwa zonyansa particles mu zimbudzi n'kopindulitsa kwa flocculation M'malo mwake, zabwino ndi yunifolomu particles zidzachititsa osauka flocculation kwenikweni.Kuchulukirachulukira kwa tinthu tonyansa nthawi zambiri kumawononga kukomoka.Panthawiyi, refluxing sediment kapena kuwonjezera coagulation aids akhoza kusintha coagulation zotsatira.

Mitundu ya flocculants

Kusankha flocculant makamaka zimadalira chikhalidwe ndi ndende ya inaimitsidwa zolimba mu zimbudzi.Ngati zolimba zomwe zayimitsidwa m'chimbudzi zili ngati gel, ma flocculants a inorganic ayenera kusankhidwa kuti asokoneze komanso kuti aziundana.Ngati flocs ndi yaying'ono, ma polima flocculants ayenera kuwonjezeredwa kapena zothandizira coagulation monga activated silika gel osakaniza ayenera kugwiritsidwa ntchito.

Nthawi zambiri, kuphatikiza ntchito inorganic flocculants ndi polima flocculants akhoza kwambiri kusintha coagulation zotsatira ndi kukulitsa kukula kwa ntchito.

Mlingo wa flocculant

Mukamagwiritsa ntchito coagulation kuti muchotse madzi oyipa aliwonse, pali ma flocculants abwino kwambiri komanso mlingo wabwino kwambiri, womwe nthawi zambiri umatsimikiziridwa ndi kuyesa.Kuchuluka kwa mlingo kungayambitsenso kukhazikika kwa colloid.

Dosing zinayendera flocculant

Mukamagwiritsa ntchito ma flocculants angapo, kutsatizana koyenera kwa dosing kumafunika kutsimikiziridwa kudzera muzoyeserera.Nthawi zambiri, ma flocculants ndi ma organic flocculants akagwiritsidwa ntchito palimodzi, ma flocculants a inorganic ayenera kuonjezedwa kaye, kenako ma organic flocculants ayenera kuwonjezeredwa.
