Kodi PAC ili ndi ntchito yotani poyeretsa madzi?

Ntchito

Zochita za PAC zimakwaniritsidwa kudzera m'magawo anayi ake kapena hydrolysis product compressed bilayer, neutralization yamagetsi, tepi web trapping, ndi adsorption bridging.

Imatsitsa ndikusefa zinthu zomwe zimatha kuthiridwa okosijeni ndi okosijeni kupangitsa COD, motero kuchepetsa COD, komanso mvula ya particulate matter.PAC ndi yotetezeka, yosamalira zachilengedwe, komanso yothandiza poyeretsa madzi oyipa.Iwo sangakhoze bwino kuchepetsa ndende ya zinthu organic, mchere ndi tizilombo mu zinyalala, komanso akhoza kuchepetsa chromaticity ndi turbidity wa zinyalala, bwino kuchepetsa kuipitsidwa, kusintha fungo la zimbudzi, kuchepetsa acidity ndi alkalinity zimbudzi, kotero kuti kuti bwino kusintha kuipitsa zimbudzi.PAC ndi chowonjezera chothandizira kuchimbudzi, chomwe chimakhala ndi gawo lofunikira pakuyeretsa zimbudzi.

Makhalidwe

PAC ndi inorganic polima coagulant.Itha kusokoneza tinthu tating'onoting'ono tomwe timayimitsidwa ndi ayoni a colloidal m'madzi, akaphatikiza, flocculate, coagulate ndi precipitate kudzera kukanikiza kwa wosanjikiza wapawiri, ma adsorption ndi magetsi a neutralization, kutsatsa ndi kutsekereza, komanso kupha ukonde, ndi zina, kuti akwaniritse chiyeretso ndi chithandizo chamankhwala. Poyerekeza ndi ma coagulants ena, PAC ili ndi ubwino wotsatirawu: Imakhala ndi ntchito zambiri komanso imagwirizana ndi madzi ambiri.N'zosavuta kupanga maluwa akuluakulu a alum mwamsanga ndipo imakhala ndi mpweya wabwino.Ili ndi mitundu yambiri yamtengo wapatali wa PH (5-9), ndipo PH mtengo ndi alkalinity yamadzi oyeretsedwa ndi ochepa.Madzi akatentha, amatha kukhalabe ndi mvula.Kuchuluka kwake kwa alkalinity ndikwambiri kuposa mchere wina wa aluminiyamu ndi chitsulo, ndipo kulibe kukokoloka pang'ono pazida.

Kugwiritsa ntchito

PAC ndi mtundu watsopano wa macromolecule coagulant wokhala ndi mphamvu zambiri.Amagwiritsidwa ntchito kwambiri mumadzi akumwa, kuyeretsedwa kwa madzi m'mafakitale, kutayira kwamadzi am'matauni amadzimadzi.Kutha kupangitsa kuti gulu lipangidwe mwachangu ndi kukula kwakukulu komanso kugwa kwamvula mwachangu.Ili ndi kusinthasintha kosiyanasiyana kwa madzi pa kutentha kosiyana komanso kusungunuka kwabwino.PAC imawononga pang'ono ndipo imayenera kudyedwa yokha komanso yabwino kuti igwire ntchito.

Mapeto

PAC ndi coagulant yofunikira pantchito yoyeretsa madzi.Iwo ali imayenera kuyeretsedwa kwambiri pa kutentha otsika, otsika turbidity ndi mkulu turbidity madzi.Komabe, popeza monomer yake imakhudzidwa ndi zinthu zakuthupi kuti ipange zinthu zomwe zili zowopsa ku thanzi la munthu, ndikofunikira kuwonetsetsa chiyero cha PAC pakuyeretsa madzi.
