Wastewater decolorizer amathetsa mavuto ochizira madzi oyipa am'matauni

Kuvuta kwa zigawo za madzi otayidwa mumsewu ndizodziwika kwambiri. Mafuta omwe amatengedwa ndi madzi otayira amatha kupanga turbidity yamkaka, thovu lopangidwa ndi zotsukira limawoneka lobiriwira, ndipo zinyalala nthawi zambiri zimakhala zofiirira. Dongosolo losakanikirana lamitundu yambirili limayika zofunikira zapamwamba madzi otayira decolorizers: imayenera kukhala ndi ntchito zingapo monga demulsification, defoaming ndi oxidation-kuchepetsa nthawi imodzi. Lipoti loyesera la malo opangira zimbudzi ku Nanjing likuwonetsa kuti kusinthasintha kwa chromaticity komwe kumakhudza kumatha kufika madigiri 50-300, ndipo chromaticity yamadzi otayira omwe amathiridwa ndi ochotsa madzi oyipa akadali ovuta kukhazikika pansi pa madigiri 30.

Ma decolorizer amakono amadzi onyansa adachita bwino kwambiri chifukwa cha mapangidwe a mamolekyu. Kutengera kusinthidwa dicyandiamide-formaldehyde polima mwachitsanzo, magulu amine ndi hydroxyl pa unyolo wa maselo ake amapanga synergistic zotsatira: gulu la amine limagwira utoto wa anionic pogwiritsa ntchito electrostatic action, ndipo gulu la hydroxyl limapanga chelate ndi ayoni azitsulo kuti athetse utoto wachitsulo. Zomwe zidagwiritsidwa ntchito zikuwonetsa kuti kuchuluka kwa kuchotsedwa kwa madzi otayidwa a chromaticity kwakwera mpaka 92%, ndipo kuchuluka kwa sedimentation ya alum flake kwakwera pafupifupi 25%. Chochititsa chidwi kwambiri ndichakuti decolorizer yamadzi otayirayi imatha kukhalabe ndi ntchito yayikulu pansi pa kutentha kochepa.

Kuchokera pamalingaliro a njira yonse yoyeretsera madzi, decolorizer yatsopano yamadzi otayira imabweretsa zosintha zingapo. Ponena za chithandizo chamankhwala, pambuyo poti chomera chamadzi chobwezeretsedwa chinatengera decolorizer yamadzi ophatikizika, nthawi yosungiramo tanki yosakanikirana mwachangu idafupikitsidwa kuchokera ku 3 mphindi mpaka masekondi 90; ponena za mtengo wogwiritsira ntchito, mtengo wa mankhwala pa tani imodzi ya madzi unachepetsedwa ndi pafupifupi 18%, ndipo kutuluka kwa sludge kunachepetsedwa ndi 15%; ponena za kuchezeka kwa chilengedwe, zotsalira zake zotsalira zimayendetsedwa pansi pa 0.1 mg/L, zomwe zili pansi kwambiri pamakampani. Makamaka pothira zimbudzi zophatikizika za sewero, zimakhala ndi mphamvu yabwino yotchingira kugwedezeka kwadzidzidzi komwe kumachitika chifukwa chamvula yamkuntho.

Kafukufuku wamakono akuyang'ana njira zitatu zatsopano: photocatalytic wastewater decolorizers amatha kudzichepetsera pambuyo pa chithandizo kuti apewe kuipitsidwa kwachiwiri; kutentha-kuyankha madzi oipa decolorizers akhoza basi kusintha mamolekyu mogwirizana ndi kutentha kwa madzi; ndi bio-inhancedmadzi otayira decolorizers kuphatikizira mphamvu zowononga ma microbial. Zatsopanozi zikupitilira kuyendetsa madzi akumatauni kuti azitha kuyenda bwino komanso kobiriwira.
