Chopopera madzi otayira ndi chopopera madzi otayira zimbudzi chimagwira ntchito bwino chikagwiritsidwa ntchito pamodzi

In Chokometsera (Polyaluminum chloride, yomwe imadziwika kuti choyeretsera madzi, yomwe imadziwikanso kuti polyaluminum chloride, polyaluminum mwachidule,PACndiFlocculant (polyacrylamide, yomwe ili m'gulu la polima yokhala ndi mamolekyulu ambiri,PAM) Pansi pa ntchitoyo, chinthu chopachikidwacho chimaphwanyika thupi ndi kuphwanyika kwa mankhwala, motero amapanga ma floc akuluakulu opachikidwa. Pansi pa kuyandama kwa gulu la thovu, "ma floccules" amayandama pamwamba pa madzi kuti apange matope, omwe amalekanitsidwa ndi madzi pogwiritsa ntchito chotsukira slag. Kuyeretsa nozzle sikudzatsekeka, ndipo kugwiritsa ntchito coagulant ndi flocculant poyeretsa zimbudzi ndi kothandiza.

Coagulant (polyaluminum chloride, yomwe imadziwikanso kuti choyeretsera madzi, yomwe imadziwikanso kuti polyaluminum chloride, yomwe imadziwikanso kuti polyaluminum, PAC) imagwiritsidwa ntchito makamaka poyeretsa madzi akumwa ndi madzi otayira m'mafakitale, komanso pochiza madzi abwino (monga zimbudzi zamafuta, kusindikiza ndi kupaka utoto zimbudzi zopangira mapepala, kusungunula zimbudzi, zomwe zili ndi mphamvu zowononga, zitsulo zolemera monga Pb, Cr ndi zimbudzi zokhala ndi F, ndi zina zotero), kuphatikiza apo, imagwiritsidwanso ntchito kwambiri popangira molondola, kuboola mafuta, chikopa, kupanga mapepala achitsulo, ndi zina zotero, coagulant imagwiritsidwa ntchito m'madzi. Panthawi yokonza, tinthu ta colloidal m'madzi timatha kulumikizidwa ndikusonkhanitsidwa pamodzi. Nthawi zambiri, njira yolumikizirana ndi kuwonjezera mankhwala panthawi yokonza madzi kuti zinyalala ziume, zisinthe mtundu, zichotse zinthu zolimba, zichotse matope ndi mabakiteriya.

Polyaluminum ferric chloride ili ndi mphamvu yabwino yolumikizirana. Polyaluminum ferric chloride (PAFC) ndi mtundu watsopano wa flocculant yopangidwa ndi cationic composite yogwira ntchito bwino kwambiri. Ili ndi ubwino wokhala ndi malo otakata, kuchotsa ma turbidity bwino, komanso dzimbiri laling'ono ku mapaipi a zida; ilinso ndi mawonekedwe a flocculant yofulumira yachitsulo, kulekanitsidwa kosavuta, magwiridwe antchito abwino pochiza madzi otentha pang'ono, komanso PH yambiri pochiza madzi. Pakadali pano, polyaluminum ferric chloride yagwiritsidwa ntchito bwino pochiza madzi akumwa, madzi amafakitale ndi madzi otayira osiyanasiyana amafakitale.

Chokometsera (polyaluminum chloride, yomwe imadziwikanso kuti choyeretsera madzi, yomwe imadziwikanso kuti polyaluminum chloride, yomwe imadziwikanso kuti polyaluminum, PAC) ili ndi mphamvu zochotsa utoto ndi kuchotsa kuipitsidwa, ndipo mphamvu yoyeretsa madzi ndi nthawi 4-6 kuposa AL2 (SO4)3. Nthawi 3-5 kuposa kuchuluka kwa ALCL3, mlingo wake ndi wochepa, mphamvu yake ndi yayikulu, mtengo wake ndi wotsika, phindu lake ndi lalikulu, kusinthasintha kwake ndi pH yosiyana siyana, kuchepa kwa pH ya madzi osaphika ndi kochepa, kotero kuti ilibe mphamvu yowononga pazida zamapaipi, palibe chifukwa chowonjezera zowonjezera zina, ndipo ma flocs amapangidwa mwachangu Komabe, ndi wandiweyani, imakhala ndi ntchito zambiri, imatha kumira kwambiri, komanso mvula imagwa mwachangu, kotero mphamvu yoyeretsa madzi ambiri otayirira ndi yodziwikiratu.
