Momwe Mungagwiritsire Ntchito Mankhwala Ochizira Madzi 3

Tili ndi chidwi kwambiri pochiza madzi onyansa pomwe kuwonongeka kwa chilengedwe kukukulirakulira.Mankhwala othandizira madzi ndi othandizira omwe ndiofunikira pazida zochotsera madzi zimbudzi. Apa timayambitsa njira zogwiritsira ntchito mankhwala osiyanasiyana amadzi.

I. Polyacrylamide pogwiritsa ntchito njira: (Kwa mafakitale, nsalu, zimbudzi za boma ndi zina zotero)

1. sungani mankhwalawa ngati yankho la 0.1% -0,3%. Kungakhale bwino kugwiritsa ntchito madzi osalowerera opanda mchere mukamasungunula (monga madzi apampopi)

Chonde dziwani: Mukamachepetsa mankhwalawa, chonde muziwongolera mayendedwe amakina osinthira, kuti mupewe kuphatikizana, mawonekedwe a nsomba ndi kutseka mapaipi.

3.Kusunthira kuyenera kupitilira mphindi 60 ndi ma rolls a 200-400 / min.Ndi bwino kuyendetsa kutentha kwamadzi ngati 20-30 , chonde onetsetsani kuti kutentha kuli pansi pa 60 .

4. Chifukwa cha mtundu waukulu wa ph womwe mankhwalawa amatha kusintha, mlingowo ukhoza kukhala 0.1-10 ppm, umatha kusintha malinga ndi mtundu wamadzi.

 Kagwiritsidwe polyaluminum mankhwala enaake: (ntchito makampani, kusindikiza ndi ankaudaya, madzi oyang'anira tauni madzi ogwiritsira, etc.)

   1. Sungunulani mankhwala olimba polyaluminum mankhwala enaake ndi madzi pa chiŵerengero cha 1:10, kuyambitsa ndi ntchito.

  2. Malinga ndi turbidity yosiyanasiyana yamadzi osaphika, mulingo woyenera kwambiri umatha kutsimikizika. Nthawi zambiri, pamene madzi akuda akuwinduka ndi 100-500mg / L, mlingowo ndi 10-20kg pa matani zikwi.

  3. Pamene madzi osaphika akwera kwambiri, mlingowo ukhoza kuwonjezeka moyenera; turbidity ikakhala yochepa, mlingowo umatha kuchepetsedwa moyenera.

  4. Polyaluminum chloride ndi polyacrylamide (anionic, cationic, non-ionic) amagwiritsidwa ntchito limodzi kuti athe kupeza zotsatira zabwino.
