Momwe Mungagwiritsire Ntchito Mankhwala Otsukira Madzi 1

Tsopano tikuyang'ana kwambiri pakutsuka madzi otayika pamene kuipitsa chilengedwe kukuipiraipira. Mankhwala otsukira madzi ndi othandizira omwe ndi ofunikira pa zida zotsukira madzi a zimbudzi. Mankhwalawa ndi osiyana pa zotsatira zake ndi njira zogwiritsira ntchito. Apa tikuwonetsa njira zogwiritsira ntchito mankhwala osiyanasiyana otsukira madzi.

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

1. Sakanizani mankhwalawa ngati yankho la 0.1%-0,3%. Ndi bwino kugwiritsa ntchito madzi osalowererapo opanda mchere powasakaniza. (Monga madzi a pampopi)

2. Dziwani izi: Mukachepetsa kuchuluka kwa mankhwala, chonde samalani kuchuluka kwa madzi omwe amagwiritsidwa ntchito pa makina oyezera okha, kuti mupewe kusonkhana kwa madzi, kutsekeka kwa madzi m'maso ndi mapaipi.

3. Kusakaniza kuyenera kuchitika kwa mphindi zoposa 60 ndi ma roll 200-400/min. Ndi bwino kuchepetsa kutentha kwa madzi kukhala 20-30 ℃, zomwe zingathandize kuti kusungunuka kusungunuke mwachangu. Koma chonde onetsetsani kuti kutentha kuli pansi pa 60 ℃.

4. Chifukwa cha kuchuluka kwa ph komwe mankhwalawa amatha kusintha, mlingo wake ukhoza kukhala 0.1-10 ppm, ndipo ukhoza kusinthidwa malinga ndi mtundu wa madzi.

Momwe mungagwiritsire ntchito chopondera utoto: (Makemikolo omwe amagwiritsidwa ntchito makamaka poyeretsa zinyalala za utoto)

1. Pa ntchito yopaka utoto, nthawi zambiri onjezerani chopondera utoto A m'mawa, kenako thirani utoto nthawi zonse. Pomaliza, onjezerani chopondera utoto B theka la ola musanapite kuntchito.

2. Malo oyezera mlingo wa utoto wa mist coagulant. Wothandizira ali pamalo olowera madzi ozungulira, ndipo malo oyezera mlingo wa wothandizila B ali pamalo otulukira madzi ozungulira.

3. Malinga ndi kuchuluka kwa utoto wopopera ndi kuchuluka kwa madzi ozungulira, sinthani kuchuluka kwa utoto wothira utoto A ndi B panthawi yake.

4. Kuyeza PH ya madzi ozungulira nthawi zonse kawiri patsiku kuti ikhale pakati pa 7.5-8.5, kuti mankhwalawa akhale ndi zotsatira zabwino.

5. Madzi ozungulira akagwiritsidwa ntchito kwa nthawi ndithu, mphamvu ya madzi ozungulira, mphamvu ya SS ndi zinthu zolimba zomwe zimapachikidwa m'madzi ozungulira zidzapitirira mtengo winawake, zomwe zimapangitsa kuti mankhwalawa akhale ovuta kusungunuka m'madzi ozungulira motero zimakhudza mphamvu ya mankhwalawa. Ndikofunikira kuyeretsa thanki yamadzi ndikuyikanso madzi ozungulira musanagwiritse ntchito. Nthawi yosinthira madzi imakhudzana ndi mtundu wa utoto, kuchuluka kwa utoto, nyengo ndi momwe zida zophikira zilili, ndipo ziyenera kutsatiridwa motsatira malangizo a katswiri wa pamalopo.
