Mu bidukikije bya none, ibibazo by'imyanda iterwa n'iterambere ry'inganda byavuwe neza mu gihugu no mu mahanga. Tuvuze kuri ibi, tugomba kuvuga uko imyanda ikoreshwa mu gutunganya amazi ihagaze. Muri make, imyanda ikorwa n'inganda nyinshi igomba gukoresha imyanda ikoreshwa mu gutunganya amazi. Yixing Cleanwater izakwereka ubumenyi n'ikoreshwa mu nzego zitandukanye.
Imiti itandukanye igabanya ibara ya polymer ikoreshwa cyane mu bijyanye no gutunganya amazi n'imyanda mu mahanga, muri yo harimo polyacrylamide (PAM) ari yo bwoko bw'ingenzi bwo gukuraho ibara rya flocculant. Ugereranyije n'imiti isanzwe igabanya ibara ry'umunyu, PAM, nk'ubwoko bushya bw'imiti itunganya amazi, ifite ibyiza byinshi: byoroshye kandi byoroshye gukoresha, ingaruka zo gukuraho ibara ry'umunyu inshuro nyinshi kurusha imiti isanzwe igabanya ibara ry'umunyu; kwihuta kw'amazi no kuyasesa, imikorere myiza yo gukuraho ibara ry'umusenyi; ingaruka zidasanzwe zo gutunganya imyanda imwe n'imwe; ibikoresho byoroshye bikenewe, ahantu hato; igiciro gito cyo gutunganya; imyanda ishobora kongera gukoreshwa no kongera gukoreshwa, nibindi.
Ishyirwa mu bikorwa ryaUmuti wo mu bwoko bwa PAM ukuraho ibara mu nzego zitandukanye zo gukoresha:
1. Gukoresha mu nganda zikora impapuro
Gukoresha PAM ifite uburemere bwinshi nk'umuti ugabanya ibara bishobora kongera umuvuduko w'imvura y'ibimera n'ibindi bintu mu mazi yera no kugabanya igihombo cyabyo. Kongeramo PAM 0.25 ~ 0.5% ku bimera bishobora kongera umuvuduko w'imvura y'ibimera ku nshuro 40 ~ 80, kugabanya ingano ikomeye mu mazi yera ku kigero cya 66%, kongera ingano y'ivu mu mpapuro, kongera umuvuduko w'ibara nk'ibumba ryera ku kigero cya 8 ~ 18%, no kuzigama ibiro 20 by'ibimera kuri toni imwe y'impapuro. Byongeye kandi, nyuma yo gukoresha PAM, amazi yera aragabanuka cyane, bigabanya umwanda uhumanya ibidukikije. Urugero, ibintu bikomeye bihagaze by'amazi y'imyanda y'amata afite pH = 6.8 ni 3000ppm. Nyuma yo kuvurwa na PAM hakoreshejwe hydrolysis ya 5 ~ 10%, uburemere bwa molekile ya miliyoni 5.5 ~ 10, na aluminium sulfate ya 500ppm, amazi yera ashobora guhinduka amazi adafite ibara kandi abonerana, kandi ibintu bikomeye bihagaze bikagabanuka bikagera munsi ya 50ppm.
2. Gukoresha imiti igabanya ibara ry'amazi mu gutunganya amazi
①Kurwanya kwagura no kugabanya igipimo
Mu gutunganya amazi n'imyanda mu nganda, amazi mabi agomba kubanza gusobanuka neza. Ibyuma bigabanya ibara bya PAM n'ibice bigabanya ibara bya 'inorganic coagulants' akenshi bikoreshwa hamwe, bishobora kugabanya cyane ikoreshwa rya 'inorganic coagulants', birinda kuziba kw'ibikoresho no kwangirika bitewe no gukoresha cyane 'inorganic coagulants', kandi bikarinda ikorwa ry'ibipimo. Ibice 37.5 bya PAM bifite uburemere bwa molekile buri munsi ya miliyoni 1 na 50 bya sodium tripolyphosphate bikoreshwa mu gukora 'scale inhibitor', ibi bikaba bishobora gukumira ubushyuhe bwinshi.
②Gutunganya imyanda y'inganda
3. Gukoresha imiti igabanya ibara ry'amazi mu gutunganya amazi yanduye mu nganda z'isukari
Umutobe w'ibisheke ukurwa mu icupa n'inganda z'isukari akenshi uba ufite umwanda kandi imiterere yawo nayo iragoye cyane. Kugira ngo haboneke umutobe w'ibisheke mwiza, hagomba kongerwamo imiti igabanya ibara. Mu bihe byashize, ibipimo by'ibishishwa bikuraho ibara mu buryo bw'umwimerere byakoreshwaga, ariko bitewe n'iterambere ry'inganda z'isukari, ibipimo by'ibishishwa bikuraho ibara mu buryo bw'umwimerere ntibishobora guhaza ibyifuzo by'umusaruro. Mu myaka ya vuba aha, ikoreshwa rya PAM mu nganda z'isukari rishobora kongera igipimo cyo gushwanyagurika kw'ibishishwa inshuro 20.
Muri make, iyo duhisemo polyacrylamide PAM decolorization flocculant dukurikije uko ibintu bimeze, tugomba kuyihitamo dukurikije uburyo butandukanye bwo kuyikoresha. Kubwibyo, guhitamo polyacrylamide nabyo ni ingenzi cyane.
Niba ukeneye ibicuruzwa byacu, nyamuneka komezaTwandikire!
