Momwe Mungagwiritsire Ntchito Mankhwala Ochizira Madzi 1

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 penti mist coagulant: (Makhemikali omwe amagwiritsidwa ntchito makamaka pochiza zimbudzi za utoto)

1. Mu ntchito yopenta, nthawi zambiri onjezani utoto wa coagulant A m'mawa, ndiyeno pukuta utoto bwino.Pomaliza, onjezerani utoto wa coagulant B theka la ola musanachoke kuntchito.

2. Malo a dosing wa penti mist coagulant A wothandizila ali polowera madzi ozungulira, ndipo nsonga ya dosing ya wothandizira B ndi pomwe madzi amazungulira.

3. Malinga ndi kuchuluka kwa utoto wopopera komanso kuchuluka kwa madzi ozungulira, sinthani kuchuluka kwa utoto wa coagulant A ndi B munthawi yake.

4. Kuyeza mtengo wa PH wa madzi ozungulira nthawi zonse kawiri pa tsiku kuti ukhale pakati pa 7.5-8.5, kuti wothandizirayo akhale ndi zotsatira zabwino.

5. Pamene madzi ozungulira amagwiritsidwa ntchito kwa nthawi, ma conductivity, mtengo wa SS ndi zolimba zomwe zimayimitsidwa m'madzi ozungulira zidzadutsa mtengo wina, zomwe zidzapangitsa kuti wothandizirayo akhale ovuta kusungunuka m'madzi ozungulira ndipo motero zimakhudza zotsatira zake. wa wothandizira uyu.Ndikoyenera kuyeretsa thanki yamadzi ndikusintha madzi ozungulira musanagwiritse ntchito.Nthawi yosintha madzi ikugwirizana ndi mtundu wa utoto, kuchuluka kwa utoto, nyengo ndi mikhalidwe yeniyeni ya zida zokutira, ndipo ziyenera kutsatiridwa motsatira malangizo a katswiri wapamalo.
