Momwe Mungagwiritsire Ntchito Mankhwala Otsukira Madzi 3

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 madigiri 20-30.℃,zimene zithandiza kuti kusungunuka kufulumizitse. 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 polyaluminum chloride: (yogwiritsidwa ntchito m'mafakitale, kusindikiza ndi kuyika utoto, madzi otayira a m'matauni, ndi zina zotero)

　　1. Sungunulani mankhwala olimba a polyaluminum chloride ndi madzi pa chiŵerengero cha 1:10, sakanizani ndikugwiritsa ntchito.

　　2. Malinga ndi kutayirira kosiyanasiyana kwa madzi osaphika, mlingo woyenera ukhoza kudziwika. Nthawi zambiri, kutayirira kwa madzi osaphika ndi 100-500mg/L, mlingo ndi 10-20kg pa matani chikwi.

　　3. Madzi osaphika akachuluka, mlingo wake ukhoza kuwonjezeredwa moyenera; madzi osaphika akachepa, mlingo wake ukhoza kuchepetsedwa moyenera.

　　4. Polyaluminum chloride ndi polyacrylamide (anionic, cationic, non-ionic) zimagwiritsidwa ntchito pamodzi kuti zitheke bwino.
