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 zimbudzi, bwino kuchepetsa kuipitsidwa, kusintha fungo la zimbudzi, kuchepetsa acidity ndi alkalinity wa zimbudzi, kuti bwino kusintha kuipitsa zimbudzi. PAC ndi chowonjezera chothandizira kuchimbudzi, chomwe chimakhala ndi gawo lofunikira pakuyeretsa zimbudzi.

Makhalidwe

PAC ndi inorganic polima coagulant. Iwo akhoza destabilize zabwino inaimitsidwa particles ndi ayoni colloidal m'madzi, akaphatikiza, flocculate, coagulate ndi mpweya kudzera psinjika wa iwiri wosanjikiza, adsorption ndi neutralization magetsi, adsorption ndi bridging, ndi mpweya ukonde kugwira, etc, kuti tikwaniritse chiyeretso, ndi ubwino PAC ali ndi zotsatira za mankhwala. mitundu yosiyanasiyana ya ntchito ndikusinthira kumadzi ambiri. Ndikosavuta kupanga maluwa akulu alum mwachangu komanso kumakhala ndi mvula yabwino. 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.
