Chotsukira utoto cha madzi otayira chimathetsa mavuto okonza madzi otayira m'matauni

Kuvuta kwa zigawo za madzi otayira m'matauni n'kodziwika kwambiri. Mafuta omwe amanyamulidwa ndi madzi otayira amapangidwa ngati mkaka, thovu lopangidwa ndi sopo lidzawoneka labuluu-lobiriwira, ndipo zinyalala zomwe zimatuluka nthawi zambiri zimakhala zakuda. Dongosolo losakanikiranali la mitundu yambiri limapereka zofunikira zambiri pa zochotsera utoto m'madzi otayira: iyenera kukhala ndi ntchito zambiri monga kuyeretsa, kuchotsa poizoni m'thupi, ndi kuchepetsa okosijeni nthawi imodzi. Lipoti loyesa la fakitale yotsukira zinyalala ku Nanjing likuwonetsa kuti kuchuluka kwa chromaticity komwe kumagwiritsidwa ntchito kumatha kufika madigiri 50-300, ndipo chromaticity ya zinyalala zomwe zimatsukidwa ndi makina ochotsera utoto achikhalidwe akadali ovuta kukhazikika pansi pa madigiri 30.

Zotsukira utoto zamadzi zinyalala zamakono achita bwino kwambiri kudzera mu kapangidwe ka mamolekyulu. Potengera chitsanzo cha modified dicyandiamide-formaldehyde polymer, magulu a amine ndi hydroxyl omwe ali pa unyolo wake wa mamolekyulu amapanga mphamvu yogwirizana: gulu la amine limagwira utoto wa anionic kudzera mu electrostatic action, ndipo gulu la hydroxyl limalumikizana ndi ma ayoni achitsulo kuti achotse utoto wachitsulo. Deta yeniyeni yogwiritsira ntchito ikuwonetsa kuti kuchuluka kwa chromaticity removal rate ya madzi otayira m'mizinda kwakwera kufika pa 92%, ndipo kuchuluka kwa alum flake sedimentation rate kwakwera ndi pafupifupi 25%. Chofunika kwambiri ndichakuti decolorizer iyi yamadzi otayira ikhoza kukhalabe ndi ntchito yayikulu pansi pa kutentha kochepa.

Poganizira za njira yonse yoyeretsera madzi, chotsukira madzi chija chatsopano chimabweretsa kusintha kwakukulu. Ponena za kugwira ntchito bwino kwa chotsukira, fakitale yamadzi yobwezeretsedwa itagwiritsa ntchito chotsukira madzi chija chophatikizana, nthawi yosungira thanki yosakaniza mwachangu inachepetsedwa kuchoka pa mphindi zitatu kufika pa masekondi 90; ponena za mtengo wogwirira ntchito, mtengo wa mankhwala pa tani imodzi ya madzi unachepetsedwa ndi pafupifupi 18%, ndipo kutulutsa kwa matope kunachepetsedwa ndi 15%; ponena za kusamala chilengedwe, kuchuluka kwa monomer komwe kumatsalira kunayang'aniridwa pansi pa 0.1 mg/L, komwe kuli kotsika kwambiri poyerekeza ndi muyezo wamakampani. Makamaka pokonza zimbudzi zamadzimadzi zophatikizana, zimakhala ndi mphamvu yabwino yotetezera ku kugunda kwadzidzidzi kwa chromatic komwe kumachitika chifukwa cha mvula yambiri.

Kafukufuku waposachedwapa akuyang'ana njira zitatu zatsopano: zochotsa utoto m'madzi otayira pogwiritsa ntchito photocatalytic zimatha kudziwononga zokha pambuyo pochiza kuti zisaipitsidwe; zochotsa utoto m'madzi otayira pogwiritsa ntchito kutentha zimatha kusintha mawonekedwe a mamolekyu malinga ndi kutentha kwa madzi; komanso zowonjezeredwa ndi bio.zochotsera utoto m'madzi otayira kuphatikiza mphamvu zowononga tizilombo toyambitsa matenda. Zatsopanozi zikupitilizabe kupititsa patsogolo chithandizo cha madzi otayira m'matauni kupita ku njira yothandiza komanso yobiriwira.
