Chimbudzi mankhwala coagulant ndi flocculant ndi zotsatira zabwino pamene ntchito pamodzi

In Coagulant (Polyaluminium Chloride, omwe amadziwika kuti oyeretsa madzi, omwe amadziwikanso kuti polyaluminium chloride, polyaluminium mwachidule,PAC) ndiFlocculant (polyacrylamide, wokhala ndi ma polima apamwamba kwambiri,PAM) Pansi pakuchitapo kanthu, chinthu choyimitsidwacho chimagwedezeka ndi kusuntha kwa mankhwala, motero kupanga flocs yaikulu yoyimitsidwa. Pansi pa mphamvu ya gulu la thovu, "floccules" imayandama pamwamba pa madzi kuti apange scum, yomwe imasiyanitsidwa ndi madzi pogwiritsa ntchito slag scraper. Kuyeretsa nozzle sikungayambitse kutsekeka, ndipo kugwiritsa ntchito coagulant ndi flocculant muzachimbudzi ndikothandiza.

Coagulant (polyaluminium kolorayidi, yomwe imadziwika kuti madzi oyeretsa, yotchedwanso polyaluminium chloride, yotchedwa polyaluminium, PAC) imagwiritsidwa ntchito makamaka pakuyeretsa madzi akumwa ndi madzi onyansa a mafakitale, komanso kuchiritsa madzi apadera (monga zimbudzi zamafuta, Kusindikiza ndi kudaya zinyalala zopangira mapepala, zimbudzi zosungunula, zokhala ndi ma radioactive, zitsulo zolemera zapoizoni monga Pb, Cr ndi zimbudzi zomwe zili ndi F, ndi zina), kuwonjezera apo, zimagwiritsidwanso ntchito kwambiri pakuponyera mwatsatanetsatane, kubowola mafuta, zikopa, zitsulo zamapepala, etc., coagulant imagwiritsidwa ntchito m'madzi Panthawi yochizira, tinthu tating'onoting'ono tomwe timakhala m'madzi titha. kulumikizidwa ndi kulumikizidwa palimodzi. Nthawi zambiri, njira ya coagulation ndikuwonjezera mankhwala panthawi yoyeretsa madzi kuti zinyalala zifanane, zisinthe, kuchotsa zolimba zomwe zayimitsidwa, kuchotsa turbidity ndi mabakiteriya.

Polyaluminium ferric chloride imakhala ndi coagulation yabwino. Polyaluminium ferric chloride (PAFC) ndi mtundu watsopano wamtundu wapamwamba wa inorganic cationic composite flocculant. Iwo ali ubwino padziko lonse, zabwino turbidity kuchotsa kwenikweni, ndi dzimbiri yaing'ono kwa mapaipi zida; ilinso ndi mikhalidwe ya kukhazikika kwachitsulo chachitsulo chothamanga kwambiri, kupatukana kosavuta, kuchita bwino pamankhwala otsika kutentha kwamadzi, komanso kuchuluka kwa PH pamankhwala amadzi. Pakalipano, polyaluminium ferric chloride yakhala ikugwiritsidwa ntchito bwino pochiza madzi akumwa, madzi a mafakitale ndi madzi onyansa osiyanasiyana a mafakitale.

Coagulant (polyaluminium chloride, yomwe imadziwikanso kuti yoyeretsa madzi, yomwe imatchedwanso polyaluminium chloride, yotchedwa polyaluminium, PAC) ili ndi mphamvu zowonongeka komanso zowonongeka, ndipo mphamvu yoyeretsa madzi ndi 4-6 nthawi ya AL2 (SO4) 3. 3-5 nthawi kuchuluka kwa ALCL3, mlingo ndi wochepa, zotsatira zake ndi zazikulu, mtengo wake ndi wotsika, phindu ndilokwera, kusinthasintha kwa pH yamtengo wapatali, kuchepetsa pH mtengo wa madzi osaphika ndi ochepa. , kotero ilibe dzimbiri pazida zamapaipi, palibe chifukwa chowonjezera zina, ndipo flocs imapanga mwachangu Komabe, ndi yokhuthala, imakhala ndi ntchito yayikulu, yozama kwambiri, komanso yamvula mwachangu, chifukwa chake madzi ochuluka amadzimadzi amadziwika bwino kwambiri.
