Zida Zoyeretsera Madzi Otayidwa
Chithandizo cha thupi
Njira iyi ndi kusakaniza ufa kapena tinthu ta zinthu zokhala ndi mapokoso monga kaboni wokonzedwa ndi dongo ndi chimbudzi, kapena kulola chimbudzi kudutsa pa fyuluta yopangidwa ndi tinthu take, kotero kuti kuipitsa m'chimbudzicho kumamatiridwa pamwamba pa zinthu zokhala ndi mapokoso kapena kusefedwa.
Pali mitundu yambiri ya zosakaniza zomwe zimagwiritsidwa ntchito pochiza kusakaniza, ndipo kusankha kwa zosakaniza ku utoto kuyenera kuganiziridwa mu polojekitiyi, ndipo zosakaniza ziyenera kusankhidwa malinga ndi mtundu wa zinyalala. Zotsatira zake zikusonyeza kuti popaka utoto m'madzi otayidwa ndi pH=12, kuchuluka kwa utoto wa anion kumatha kufika 95%-100% pogwiritsa ntchito ma silicon polymers (methyl oxygen) ngati zosakaniza. Kaolin ndi yosakaniza. Kafukufuku wasonyeza kuti kaolin imatha kuyamwa utoto wachikasu mwachindunji m'madzi otayidwa pogwiritsa ntchito njira yayitali yochizira organic cation.
Chithandizo cha mankhwala
Imagawidwa makamaka m'mitundu iwiri ya njira yolumikizirana ndi njira yolumikizirana, yomwe imakhala ndi zotsatira zake pochiza madzi.
Njira yolumikizirana makamaka imaphatikizapo njira yolumikizirana ndi mpweya woyandama. Ma coagulants ambiri omwe amagwiritsidwa ntchito makamaka ndi mchere wa aluminiyamu kapena mchere wachitsulo, womwe umagwiritsidwa ntchito kwambiri ndi aluminiyamu chloride (PAC) yomwe imagwira ntchito bwino polumikiza, ndipo ferrous sulfate ndi mtengo wotsika kwambiri. Ubwino waukulu wa njira yolumikizirana ndi kuyenda kosavuta kwa njira, kugwiritsa ntchito bwino ndi kuyang'anira, ndalama zochepa zogulira zida, malo ochepa komanso magwiridwe antchito ambiri ochotsa utoto wa hydrophobic. Zoyipa zake ndi mtengo wokwera wogwirira ntchito, matope ambiri komanso kusowa madzi okwanira m'thupi, komanso zotsatira zoyipa za utoto wa hydrophilic.
Pali njira zingapo zopangira okosijeni, monga ozoni oxidation ndi kuwala okosijeni. Njira ya okosijeni ya ozoni imatha kupereka zotsatira zabwino zochotsera mtundu pa utoto wambiri, koma zotsatira zoyipa zochotsera mtundu pa sulfure, kuchepetsa, utoto ndi utoto wina wosasungunuka. Chithandizo cha Photooxidation popaka utoto pogwiritsa ntchito madzi otayira ndi chachikulu, koma ndalama zomwe zimagwiritsidwa ntchito ndi zida zamagetsi ziyenera kuchepetsedwa kwambiri, kugwiritsa ntchito njira iyi m'nyumba si mabizinesi ambiri.
Chithandizo cha electrolytic
Kupaka utoto wa electrolysis kumakhudza bwino njira yopangira utoto wa madzi otayidwa okhala ndi utoto wa asidi, kuchuluka kwa utoto ndi 50% ~ 70%, koma zotsatira za chithandizo pa madzi otayidwa okhala ndi utoto wozama komanso COD wambiri ndi zoyipa.
Zikumveka kuti ziwerengero, mitundu yonse ya utoto chifukwa cha mphamvu zosiyanasiyana zamagetsi mu chithandizo cha electrolytic cha COD removal rate yawo ili ndi kusiyana kwakukulu, dongosolo la COD removal rate nthawi zambiri limakhala: sulfide dyes, VAT dye-acid dyes, reactive dye-neutral dyes, direct dye-cationic dyes.
