Momwe Mungagwiritsire Ntchito Mankhwala Ochizira Madzi 2

Momwe Mungagwiritsire Ntchito Mankhwala Otsuka Madzi 3

Tsopano timayang'ana kwambiri pochiza madzi otayira pamene kuipitsidwa kwa chilengedwe kukuipiraipira.Ma mankhwala ochizira madzi ndi othandizira omwe ali ofunikira pazitsulo zopangira madzi otayira. Mankhwalawa ndi osiyana ndi zotsatira ndi kugwiritsa ntchito njira.Apa tikuwonetsa njira zogwiritsira ntchito mankhwala osiyanasiyana opangira madzi.

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

1.Dilute mankhwala monga 0.1% -0,3% yankho.Ndi bwino kugwiritsa ntchito madzi opanda mchere pothira. (Monga madzi apampopi)

2.Chonde zindikirani: Pamene diluting mankhwala, chonde kulamulira mlingo otaya wa Makinawa dosing makina, kupewa agglomeration, vuto maso a nsomba ndi blockage mu mapaipi.

3.Kugwedeza kuyenera kupitirira mphindi 60 ndi 200-400 masikono / min. Ndi bwino kulamulira kutentha kwa madzi monga 20-30.℃, zomwe zidzafulumizitsa kusungunuka.Koma chonde onetsetsani kuti kutentha kuli pansi pa 60℃.

4.Chifukwa cha kuchuluka kwa ph komwe mankhwalawa amatha kusintha, mlingo ukhoza kukhala 0.1-10 ppm, ukhoza kusinthidwa molingana ndi madzi.

Momwe mungagwiritsire ntchito polyaluminium chloride: (yomwe imagwira ntchito kumakampani, kusindikiza ndi utoto, madzi onyansa a tauni, etc.)

　　1. Sungunulani cholimba polyaluminium kolorayidi mankhwala ndi madzi pa chiŵerengero cha 1:10, kusonkhezera ndi ntchito.

　　2. Malinga ndi turbidity yosiyana ya madzi aiwisi, mulingo woyenera kwambiri ungadziwike.Nthawi zambiri, pamene turbidity ya madzi yaiwisi ndi 100-500mg/L, mlingo ndi 10-20kg pa matani chikwi.

　　3. Pamene chipwirikiti cha madzi osaphika chakwera, mlingo ukhoza kuwonjezeka moyenerera;pamene turbidity ili yotsika, mlingo ukhoza kuchepetsedwa moyenera.

　　4. Polyaluminium chloride ndi polyacrylamide (anionic, cationic, non-ionic) amagwiritsidwa ntchito palimodzi kuti apeze zotsatira zabwino.
