Mubidukikije bigezweho, ibibazo byimyanda iterwa niterambere ryinganda byafashwe neza mugihugu ndetse no mumahanga. Tuvuze kuri ibi, tugomba kuvuga uko decolorizing flocculants mugutunganya amazi. Ahanini, imyanda ituruka mu nganda nyinshi ikeneye gukoresha decolorizing flocculants. Yixing Amazi meza azakumenyesha ubumenyi hamwe nibisabwa mubice bitandukanye.
Imiti itandukanye ya polymer decolorizing flocculants ikoreshwa cyane mubijyanye n’amazi y’inganda no gutunganya imyanda mu mahanga, muri yo hakaba harimo polyacrylamide (PAM) nubwoko nyamukuru bwo gutaka flokculant. Ugereranije n’ibisanzwe byumunyu ngugu, PAM, nkubwoko bushya bwo gutunganya amazi, ifite ibyiza byinshi: byoroshye kandi byoroshye gukoresha, ingaruka ya flocculation irikubye inshuro icumi ugereranije numunyu ngengabuzima udasanzwe utunganya ibimera; kwihuta kwihuta no kwihuta, umuvuduko mwinshi wo gutemba; ingaruka zidasanzwe zo gutunganya imyanda imwe n'imwe; ibikoresho byoroshye bisabwa, ikirenge gito; amafaranga make yo kwivuza; umwanda urashobora gutunganywa no gukoreshwa, nibindi.
Gushyira mu bikorwaPAM irimbisha flocculant mubice bitandukanye byo gusaba:
1. Gusaba mubikorwa byo gukora impapuro
Gukoresha uburemere buke bwa PAM nka flocculant decolorizing birashobora kongera umuvuduko wimvura yibintu nibindi bintu mumazi yera bikagabanya igihombo cyabyo. Ongeraho 0.25 ~ 0.5% PAM kuri pulp irashobora kongera umuvuduko wibimera byinshuro inshuro 40 ~ 80, kugabanya ibintu bikomeye mumazi yera hafi 66%, kongera ivu ryimpapuro, kongera igipimo cyo kugumana pigment nkibumba ryera kuri 8 ~ 18%, kandi bizigama 20 kg byimbuto kuri toni yimpapuro. Byongeye kandi, nyuma yo gukoresha PAM, ubwinshi bwamazi yera buragabanuka cyane, bigabanya kwanduza ibidukikije. Kurugero, ibimera byahagaritswe byamata yera yera yamazi hamwe na pH = 6.8 ni 3000ppm. Nyuma yo kuvurwa na PAM ifite hydrolysis ya dogere 5 ~ 10%, uburemere bwa molekile ingana na miliyoni 5.5 ~ 10, na 500ppm ya aluminium sulfate, amazi yera arashobora guhinduka amazi atagira ibara kandi abonerana, kandi ibimera byahagaritswe bikagabanuka munsi ya 50ppm.
2. Gukoresha decolorizing flocculants mugutunganya amazi
①Kurwanya gupima no kumanuka
Mu mazi y’inganda no gutunganya imyanda, amazi meza agomba kubanza gusobanurwa. PAM decolorizing flocculants hamwe na coagulants ya organic organique ikoreshwa kenshi muguhuza, bishobora kugabanya cyane ikoreshwa rya coagulants idasanzwe, kwirinda guhagarika ibikoresho no kwangirika bitewe no gukoresha cyane imiti mvaruganda, kandi ikabuza gushiraho igipimo. Ibice 37.5 bya PAM bifite uburemere bwa molekuline iri munsi ya miriyoni 1 nibice 50 bya sodium tripolyphosifate ikoreshwa mugukora inibitori, ishobora ahanini gukumira igipimo cyoguhindura ubushyuhe bukabije.
②Gutunganya imyanda mvaruganda
3. Gukoresha decolorizing flocculants mugutunganya amazi mabi munganda zisukari
Umutobe w'isukari wakuwe mu icapiro n'inganda z'isukari ubusanzwe uba wuzuye kandi ibiyigize nabyo biragoye. Kugirango ubone umutobe wibisheke bisukuye, hagomba kongerwamo imiti isobanura. Mu bihe byashize, ubusanzwe ibinyabuzima byakoreshwaga mu binyabuzima byakoreshwaga, ariko hamwe n’iterambere ry’inganda z’isukari, ibinyabuzima bitangiza umubiri ntibishobora kongera gukenera umusaruro. Mu myaka yashize, ikoreshwa rya PAM mu nganda zisukari rishobora kongera igipimo cy’imitsi inshuro 20.
Muncamake, mugihe duhisemo polyacrylamide PAM decolorisation flocculant dukurikije uko ibintu bimeze, tugomba guhitamo dukurikije ibintu bitandukanye bisabwa. Kubwibyo, guhitamo polyacrylamide nabyo ni ngombwa cyane.
Niba ukeneye ibicuruzwa byacu, nyamuneka wumve nezatwandikire!
