Mu Disembala, 2021, zoyendetsa makonda zomwe zidasungunuka zidamalizidwa ndikukwaniritsa mulingo wafakitale kuti uperekedwe bwino.
Dissolved Air Flotation (DAF System) ndi njira yoyeretsera madzi yomwe imamveketsa madzi oipa (kapena madzi ena, monga mtsinje kapena nyanja) pochotsa zolimba zomwe zayimitsidwa kapena mafuta & girisi.Amagwiritsidwa ntchito kwambiri popangira madzi oyipa pakulekanitsa kwamadzi olimba, amatha kuchotsa zolimba, mafuta & mafuta ndi colloidal mogwira mtima.Pakadali pano, COD, BOD imatha kuchepetsedwa.Ndiwo zida zazikulu zopangira madzi oyipa.
Mawonekedwe a Kapangidwe
DAF System makamaka imakhala ndi pampu ya mpweya yosungunuka, mpweya wa compressor, chotengera cha mpweya chosungunuka, thupi la thanki lachitsulo la rectangle, skimmer system.
1. Kugwiritsa ntchito kosavuta komanso kasamalidwe kosavuta, kuwongolera bwino kuchuluka kwa madzi otayira ndi mtundu wake.
2.The thovu yaying'ono opangidwa ndi kusungunuka mpweya chotengera ndi 15-30um, ndi zomatira ndi flocculant mwamphamvu tikwaniritse bwino flotation kwenikweni.
3. Wapadera GFA kusungunuka mpweya dongosolo, dzuwa mkulu wa Kutha mpweya angafikire 90%+, mphamvu amphamvu kutseka
4. Unyolo-mbale mtundu skimmer, ntchito khola ndi mkulu dzuwa kuti zinyalala.
Chiphunzitso cha Ntchito
Madzi osungunuka a mpweya opangidwa ndi GFA amaponyedwa mu chotulutsa mpweya pochepetsa kupanikizika.15-30um ming'oma yaying'ono yochokera ku chotulutsa mpweya imatha kumamatira zolimba zomwe zayimitsidwa zimawapangitsa kukhala opepuka kuposa madzi, ndiye zolimba zophatikizidwa ndi thovu yaying'ono zimatha kuyandama pamwamba kuti apange scum wosanjikiza womwe ungatayidwe ndi skimmer system mu thanki ya sludge. .Madzi aukhondo otsika amalowa m’thanki yamadzi aukhondo.Pafupifupi 30% ya madzi oyera amasinthidwanso ku dongosolo la GFA pomwe ena amatulutsidwa kapena kuponyedwa kunjira ina.
Kugwiritsa ntchito
Dongosolo la DAF, monga njira imodzi yochitira zinthu zonyansa, imagwiritsidwa ntchito kwambiri muumisiri woyeretsa zimbudzi.Itha kugwiritsidwa ntchito m'mafakitale awa:
1. Paper industry - zamkati zobwezeretsanso m'madzi oyera ndi madzi oyera ogwiritsidwanso ntchito.
2. Makampani opanga nsalu, kusindikiza ndi utoto - kuchepetsa mtundu wa chromaticity ndi kuchotsa SS
3. Nyumba yophera ndi chakudya
4. Petro-chemical industry - mafuta-madzi kulekana
