Kuchita Ndi Njira Yamadzimadzi Polymerized Ferric Sulfate

Chatsopano, apamwamba ndi mkulu-mwachangu chitsulo mchere zosakaniza polima flocculant zimagwiritsa ntchito kwambiri madzi kuyeretsedwa kwenikweni, madzi abwino, palibe zinthu zoipa monga zotayidwa, klorini ndi ayoni heavy metal, ndipo palibe kutengerapo madzi ayoni chitsulo.Ndizopanda poizoni, zopanda vuto, zotetezeka komanso zodalirika.Zili ndi zotsatira zochititsa chidwi pakuchotsa turbidity, decolorization, deoiling, dehydration, sterilization, deodorization, kuchotsa algae, COD, BOD ndi ayoni azitsulo zolemera m'madzi.Amagwiritsidwanso ntchito popangira madzi otayira m'mafakitale, monga kusindikiza ndi kudaya madzi oipa.Amagwiritsidwanso ntchito kwambiri poponya, kupanga mapepala, mankhwala, kupukuta ndi zina zotero.

Poyerekeza ndi ma flocculants ena, polymeric ferric sulfate ili ndi izi:
1. Chatsopano, apamwamba ndi apamwamba chitsulo mchere inorganic polima flocculant;
2. Kuchita bwino kwa coagulation, alum wandiweyani komanso kuthamanga kwachangu;
3. Zabwino kwambiri zoyeretsa madzi, madzi abwino, opanda zinthu zovulaza monga aluminiyamu, klorini ndi ayoni zitsulo zolemera, ndipo palibe gawo la madzi kutengerapo ma ayoni achitsulo, opanda poizoni, opanda vuto, otetezeka komanso odalirika;
4. Zotsatira zazikulu za kuchotsa turbidity, decolorization, deoiling, dehydration, sterilization, deodorization, kuchotsa algae, COD, BOD ndi heavy metal ions m'madzi;
5. Sinthani kumitundu yambiri ya pH yamadzi am'madzi, yomwe ndi 4-11 ndi 6-9.Kusiyanasiyana kwa pH mtengo ndi alkalinity yonse yamadzi yaiwisi pambuyo pa kuyeretsedwa ndi yaying'ono, ndipo zowonongeka kwa zipangizo zothandizira ndizochepa;
6. Kuyeretsedwa kwa madzi oipitsidwa pang'ono, algae omwe ali, kutentha kochepa komanso madzi osaphika otsika ndi ochititsa chidwi, makamaka chifukwa cha madzi osaphika kwambiri;
7. Mlingo ndi wochepa, mtengo wake ndi wotsika, ndipo mtengo wamankhwala ukhoza kupulumutsidwa ndi 20% - 50%.

Njira zazikulu
1. Amawonjezedwa kutsogolo kwa thanki ya pre sedimentation.Pano, osati phosphate yokha m'madzi yaiwisi yomwe imatha kuchiritsidwa, komanso zinthu zomwe zayimitsidwa m'madzi zimatha kudsorbed ndikukhazikika.Komabe, kumawonjezera kuchuluka kwa sludge anapanga, amachotsa wambirimbiri insoluble organic nkhani, zimakhudza wotsatira tizilombo denitrification ndi kwachilengedwenso phosphorous kuchotsa, ndipo kumawonjezera vuto la sludge mankhwala.
2. Amawonjezeredwa mu thanki yachiwiri ya sedimentation ngati coagulant.Pambuyo Kutha izo, polima mankhwala adzakhala coagulate mankwala m'madzi, ndiyeno kuchita kwambiri phosphorous kuchotsa mankhwala kudzera mpweya kuyandama kapena sedimentation kusefera kulekana.Kuonjezera chitsulo cha polima pano sikungokhala ndi kuchuluka kwa phosphorous kuchotsa, komanso kumakhala ndi mphamvu zokopa za zinthu zina zoyimitsidwa m'madzi.Komabe, poyerekeza ndi njira ya biochemical, njirayi imawonjezera mlingo wa mankhwala ndipo imapanga matope ambiri, ndipo thanki yomaliza ya sedimentation iyenera kukhazikitsidwa kuti iwonetsetse kuti kayendedwe kabwino ka kusefera kotsatira.
