Momwe Mungagwiritsire Ntchito Mankhwala Ochizira Madzi 1

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 kwa madzi ngati 20-30 ℃, zomwe zithandizira kuvunda.Koma chonde onetsetsani kuti kutentha kuli pansipa 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.

Momwe mungagwiritsire ntchito coagulant ya utoto: (Mankhwala omwe amagwiritsidwa ntchito makamaka pochotsa zimbudzi)

1. Pogwiritsa ntchito utoto, onjezerani utoto wozungulirana ndi A m'mawa, kenako ndikuwaza utoto mwachizolowezi. Pomaliza, onjezerani nkhungu coagulant B theka la ola musanachoke kuntchito.

2. Malo opangira utoto wa utoto wozizira Wothandizila ali polowera madzi, ndipo dosing wa wothandizila B ndiye potulutsa madzi.

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

4. Kuyeza mtengo wa PH wamadzi oyenda pafupipafupi kawiri patsiku kuti akhale pakati pa 7.5-8.5, kuti wothandizirayu akhale ndi zotsatira zabwino.

5. Madzi oyenda akagwiritsidwa ntchito kwakanthawi, mayendedwe ake, mtengo wa SS ndi zolimba zoyimitsidwa zamadzi ozungulira zimapitilira phindu linalake, zomwe zimapangitsa wothandizirayu kukhala wovuta kusungunuka m'madzi ozungulira motero zimakhudza zotsatira zake wa wothandizirayu. Tikulimbikitsidwa kuyeretsa thanki yamadzi ndikusintha madzi oyenda musanagwiritse ntchito. Nthawi yosinthira madzi imakhudzana ndi mtundu wa utoto, kuchuluka kwa utoto, nyengo ndi momwe zinthu ziliri ndi zida zokutira, ndipo zikuyenera kuchitidwa molingana ndi malingaliro a waluso pamalopo.
