Imyanda yangiza imyanda ikemura ibibazo byo gutunganya amazi mabi ya komini

Ubwinshi bwibigize amazi y’amakomine biragaragara cyane. Amavuta atwarwa no kugaburira amazi mabi azabyara amata, ifuro ikorwa nudukingirizo tuzagaragara nkubururu-icyatsi, kandi imyanda yimyanda iba yijimye. Sisitemu y'amabara menshi avanze ashyiraho ibisabwa hejuru imyanda yangiza: ikeneye kugira imirimo myinshi nko gusenya, gusebanya no kugabanya okiside-icyarimwe. Raporo y’ibizamini y’uruganda rutunganya imyanda i Nanjing yerekana ko ihindagurika rya chromaticity ry’ingaruka zaryo rishobora kugera kuri dogere 50-300, kandi chromaticité y’imyanda ivurwa na decolorizeri y’amazi gakondo iracyagoye guhagarara munsi ya dogere 30.

Amazi meza ya decolorizeri bageze ku mikorere isimbuka binyuze mu bishushanyo mbonera. Dufashe urugero rwa dicyandiamide-formaldehyde polymer nkurugero, amine na hydroxyl mumatsinda yayo ya molekuline bigira ingaruka zifatika: itsinda rya amine rifata amarangi ya anionic binyuze mumikorere ya electrostatike, kandi hydroxyl group chelates hamwe na ion yicyuma kugirango ikureho amabara. Imibare ifatika isaba yerekana ko igipimo cyo gukuraho chromaticity y’amazi y’amazi ya komine cyiyongereye kugera kuri 92%, naho igipimo cy’imyuka ya alum flake cyiyongereyeho 25%. Ikigaragara cyane ni uko iyi decolorizer yamazi ashobora gukomeza gukora cyane mugihe cy'ubushyuhe buke.

Urebye uburyo bwose bwo gutunganya amazi, decolorizer nshya yamazi azana iterambere ryinshi. Mu rwego rwo kuvura neza, nyuma y’uruganda rw’amazi rwongeye kugarurwa rwemeje decolorizer y’amazi y’amazi, igihe cyo kugumana ikigega kivanga vuba cyagabanutse kuva ku minota 3 kugeza ku masegonda 90; kubijyanye nigiciro cyo gukora, igiciro cyimiti kuri toni yamazi yagabanutseho 18%, naho ibicuruzwa biva mu mahanga byagabanutseho 15%; mubijyanye no kubungabunga ibidukikije, ibiyirimo bya monomer bisigaye byagenzuwe munsi ya 0.1 mg / L, biri munsi yuburinganire bwinganda. Cyane cyane iyo itunganya imiyoboro yimyanda ihuriweho, ifite ubushobozi bwiza bwo gukwirakwiza impanuka zitunguranye ziterwa na mvura nyinshi.

Ubushakashatsi bugezweho bwibanze ku nzira eshatu zigezweho: fotokatalitiki y’amazi yangiza imyanda irashobora kwangirika nyuma yo kuvurwa kugirango birinde umwanda wa kabiri; Ubushyuhe-busubiza amazi yangiza imyanda irashobora guhita ihindura ihinduka rya molekile ukurikije ubushyuhe bwamazi; na bio-yazamuyeimyanda yangiza guhuza ubushobozi bwa mikorobe. Ibi bishya bikomeje gutwara amazi y’amakomine yerekeza ku cyerekezo cyiza kandi kibisi.
