Kusintha koipa kwa anionic polyacrylamide ntchito

Anionic Polyacrylamide zimagwiritsa ntchito kulimbikitsa flocculation zimbudzi, ali makhalidwe a polima electrolyte mu ndale ndi zamchere sing'anga, tcheru ndi electrolytes mchere, ndi ayoni mkulu mtengo zitsulo akhoza mtanda zikugwirizana mu insoluble gel osakaniza, amene makamaka ntchito zoweta. madzi, mafakitale ndi m'tawuni zimbudzi mankhwala, komanso angagwiritsidwe ntchito inorganic sludge kuchepa madzi m'thupi.

Atatu waukulu ntchito madera anionic polyacrylamide:

M'makampani opangira zitsulo ndi zitsulo, amagwiritsidwa ntchito kuyeretsa madzi ochapira gasi mung'anjo yotseguka, kufotokozera madzi otayira muzitsulo zazitsulo ndi zomera zokolola, kuyeretsedwa kwa electrolytes ndi kulongosola kwa electroplating zinyalala zamadzimadzi.

Mu migodi, ntchito malasha kutsuka kumveka madzi ndi tailings flotation, woyera malasha kusefera, tailings (slag) kuchepa madzi m'thupi, flotation tailings kumveka, kuganizira thickening ndi kusefera, potaziyamu alkali otentha kusungunula ndi flotation processing madzimadzi kumveka, fluorite ndi barite flotation tailings. , yaiwisi brine pokonza mchere, sludge dehydration kumveketsa ndi phosphate mgodi kuchira mankhwala madzi.

M'matauni ndi m'mafakitale amadzi otayira, amagwiritsidwa ntchito kukonza kuchotsedwa kwa zolimba zoyimitsidwa, BOD ndi phosphate m'madzi onyansa.Powonjezera 0.25mg/L hydrolyzed Polyacrylamide ku thanki yoyamba yamadzi otayira sedimentation, mitengo yochotsa zinthu zomwe zaimitsidwa ndi BOD zitha kuonjezedwa mpaka 66% ndi 23%, motero.Powonjezera 0.3mg/L anionic polyacrylamide ku thanki yachiwiri yamadzi onyansa amadzimadzi, kuchotsedwa kwa zinthu zomwe zaimitsidwa ndi BOD zitha ziwonjezeke mpaka 87% ndi 91%, motero, ndi kuchotsedwa kwa phosphorous kumatha kuchuluka kuchokera ku 35% mpaka 91%. .Pochiza madzi akumwa ndi madzi onyansa apanyumba, amagwiritsidwa ntchito pofotokozera pamwamba, kuwunikira madzi otayira komanso kusintha kwa filtrate.

The solubility wa anionic polyacrylamide kukonzekera umayamba:

1, yomwe imagwiritsidwa ntchito pomanga zimbudzi, chiwerengero chovomerezeka cha 0.1%

2, choyamba kuwaza ufa m'madzi apampopi, ndikuyambitsanso pa liwiro lapakati la 40-60 RPM kuti polima asungunuke m'madzi asanawonjezeke.

3, Pa kuyesera, kutenga 100ml madzi oipa, kuwonjezera 10% polyacrylamide njira, ndi kusonkhezera pang'onopang'ono, ntchito syringe pang'onopang'ono kuwonjezera PAM yankho, 0.5ml nthawi iliyonse, malinga ndi kukula kwa kwaiye alum maluwa ndi kuyandikira kwa flocculant, kumveka kwa supernitant, mlingo wa sedimentation, mlingo kuti mudziwe wothandizira woyenera.
