Ubuyobozi bwuzuye bwo gutunganya amazi neza
Uburyo bwo gutunganya amazi bushingiye cyane ku mikorere yo gufunga no gukurura amazi kugira ngo akureho uduce duto, ibintu bikomoka ku binyabuzima, n'amazi ahinduka umuyoboro w'amazi. Mu binyabutabire bikoreshwa cyane muri ubu buryo harimoPolyaluminum Chloride (PAC)naPolyacrylamide (PAM).
Iyo bikoreshejwe neza hamwe, PAC na PAM bishobora kunoza cyane imikorere y’amazi, kugabanya ingano y’ibinyabutabire, no kongera ubushobozi bwo gufunga imyanda. Ariko, guhuza nabi—nk’uburyo butanoze bwo gupima cyangwa gushyiramo ibipimo—bishobora kugabanya imikorere myiza yo kuvura.
Iyi nkuru itanga ubuyobozi bwuzuye bwa tekiniki ku buryo bwo guhuza PAC na PAM mu gufungana kw'amaraso, harimo amahame ngenderwaho, uburyo bwo gutanga ingero, ingamba zo kunoza imikorere y'umubiri, hamwe n'amakosa asanzwe yo kwirinda.
Gusobanukirwa uruhare rwa PAC na PAM mu guhuza kw'imitsi
Mbere yo kuganira ku buryo bwo kubivanga, ni ngombwa gusobanukirwa uburyo buri kintu gikora mu nzira yo gufungana no gufungana kw'amaraso.
Polyaluminum Chlorideni polymer coagulant ikoreshwa cyane mu gutunganya amazi yo kunywa, gutunganya amazi yanduye mu nganda, no mu miyoboro y'amazi yanduye yo mu mujyi.
PAC ikora cyane cyane binyuze mu kugabanya ingufu no kuzishyira mu mazi. Mu buryo bwinshi bw'amazi karemano, uduce duto dufite ingufu nke, zituma tudakwirakwira kandi zikatubuza kwishyira mu mazi. PAC isohora iyoni za aluminiyumu zifite ingufu nziza zigabanya ingufu. Iyo zimaze gucika intege, uduce dutangira kwishyira hamwe tukavamo utunyangingo duto.
Ibyiza bya PAC
- Ubushobozi bukomeye bwo gufungana kw'amaraso
- Gukuraho umwanda neza
- Uburyo pH ikoreshwa mu gupima ubunini
- Ubunini bw'imyanda buri hasi ugereranije n'umunyu gakondo wa aluminiyumu
- Bikwiriye gusukura amazi meza ndetse no gutunganya amazi yanduye
Ariko, PAC yonyine ishobora gukora uduce duto duto duto dushira buhoro buhoro, ari na ho PAM iba ingenzi.
Polyacrylamideni organic polymer flocculant ikoreshwa mu kongera flecculant no gutuza. PAM ikora cyane cyane binyuze mu guhuza polymer. Imiyoboro yayo miremire ya molekile ihuza microflocs nyinshi hamwe, igakora flocs nini kandi nini zituza vuba.
Ubwoko bwa PAM bukoreshwa mu gusukura amazi
Hari ubwoko butatu bw'ingenzi:
- PAM ya Anionic (APAM)
- PAM ya Cationic (CPAM)
- PAM itari iy'ionic (NPAM)
Muri sisitemu nyinshi za PAC + PAM, PAM ya anionic ikunze gukoreshwa kuko PAC yamaze gutanga uburyo bwo kugabanya amashanyarazi neza.
Akamaro ka PAM mu mikorere y'amaraso afungana
- Yongera ingano y'amafi
- Yihutisha ubushyuhe bw'amazi
- Binoza uburyo amazi yo mu mazi akoreshwa mu gukuraho ibishanga
- Bigabanya igipimo cya PAC
- Yongera imikorere myiza yo kuyungurura
Impamvu PAC na PAM bikoreshwa hamwe
Gukoresha PAC na PAM hamwe bitanga ingaruka zo guhuza amaraso no gufungana.
Uburyo bw'intambwe ku yindi
PAC igabanya ubukana bw'uduce duto, igakuraho charges, kandi igakora micro-flocs.
Imiyoboro ya PAM ihuza microflocs mu maflocs manini.
Amafi manini arohama vuba mu bigega byo gutwika.
Ibyiza byo gukoresha polyaluminum chloride na polyacrylamide hamwe
- Gukuraho umwanda mwinshi
- Igihe cyo kwihuta cyo gutuza
- Kugabanya ikoreshwa ry'imiti
- Ubunini bw'imyanda bwagabanutse
- Imikorere myiza y'urufunguzo
Kubera izi nyungu, PAC + PAM ikoreshwa cyane muri:
- Inganda zitunganya amazi yanduye zo mu mujyi
- Gutunganya amazi yanduye mu nganda
- Gusobanura amazi yanduye yo mu bucukuzi bw'amabuye y'agaciro
- Gutunganya amazi yanduye mu nganda zikora impapuro
- Gusobanura neza amazi yo kunywa
Uburyo bwo Gupima PAC na PAM neza
Kimwe mu bintu by'ingenzi bituma amaraso afunga neza ni uko uburyo akoreshwa mu gupima amaraso bukurikirana neza. Uburyo bukwiye ni ubu:PAC ya mbere → PAM ya kabiri
Impamvu PAC igomba kongerwaho mbere na mbere
PAC igomba kubanza kugabanya imbaraga z'uduce duto hanyuma igakora microflocs z'ibanze. Iyo hatabayeho iyi ntambwe, molekile za PAM zizashonga mu mazi kandi ntizishobora gufatanya neza uduce duto.
Intambwe zisanzwe zo gupima
- Ikigega cyo kuvanga vuba
- Gutera PAC
- Kuvanga vuba (amasegonda 30–60)
- Gutera PAM
- Kuvanga buhoro buhoro (igihe cyo guhuza imiterere y'umubiri)
- Gutwika
⚠️ Ikosa risanzwe:Kongeramo PAM mbere ya PAC ni ikosa rikunze kugaragara rituma habaho floc mbi no gusesagura imiti.
Igipimo cyiza cya PAC na PAM
Igipimo gitandukana bitewe n'ubwiza bw'amazi, ubushuhe, n'ubwinshi bw'ibintu bikomeye bihagaze.
Ingano zisanzwe ni izi zikurikira
Igipimo cya PAC
Amazi yo kunywa: 5–50 mg/L
Amazi yanduye yo mu nganda: 30–200 mg/L
Igipimo cya PAM
Ubusanzwe ni hasi cyane ugereranyije na PAC
Ingano isanzwe: 0.1–3 mg/L
Itegeko ry'ingenzi
Igipimo cya PAM ubusanzwe ni 1/100 kugeza 1/50 cy'igipimo cya PAC.
PAM ikabije ishobora gutera:
- Amashuka afite imitako
- Gutuza nabi
- Kuziba kw'akayunguruzo
Kubwibyo, gupima ibinini ni ngombwa kugira ngo hamenyekane ingano nziza.
Gutegura ibisubizo bya PAC na PAM
Gutegura imiti neza ni ingenzi kugira ngo ipimwa neza.
* Gutegura igisubizo cya PAC
PAC isanzwe itegurwa nk'umuti wa 5–10%.
PAC ishonga vuba cyane kandi ishobora gukoreshwa mu munsi umwe.
*Gutegura igisubizo cya PAM
PAM isaba kwitegura neza kurushaho.
Uburyo busanzwe bwo kwibanda ku bintu:
igisubizo cya 0.05–0.1%
Urugero rw'itegurwa:
- Shyiramo amazi mu gikoresho cyo kuvanga
- Suka buhoro buhoro ifu ya PAM
- Kangura buhoro buhoro mu gihe cy'iminota 30–60
- Reka gusaza mu gihe cy'iminota 30
Ingingo z'ingenzi:
- Irinde kuvanga vuba cyane (bishobora guca iminyururu ya polymer)
- Koresha amazi meza
- Tegura umuti mushya buri munsi
Uburyo bwo kuvanga ibintu kugira ngo umuntu agire ubwivumbure bukora neza
Kuvanga imbaraga bigira ingaruka zikomeye ku mikorere y'amaraso afunganye.
Icyiciro cyo kuvanga vuba
Intego: gukwirakwiza PAC vuba.
Ibipimo bisanzwe:
- Igihe: amasegonda 30–60
- Umuvuduko w'umuvuduko (G): 700–1000 s⁻¹
Icyiciro cyo gukurura ingano y'amazi
Intego: kureka amashu akure adacitse.
Ibipimo bisanzwe:
- Igihe: Iminota 15–30
- Umuvuduko w'umuvuduko: 20–80 s⁻¹
PAM ikunze kongerwaho mu ntangiriro y'icyiciro cyo gukurura.
Isuzuma ry'ibinini kugira ngo hakorwe neza uburyo bwo gutunganya imikorere
Ikizamini cy'icupa ni bwo buryo bwizewe cyane bwo kumenya uruvange rwiza rwa PAC na PAM.
Uburyo busanzwe bwo gupima ibinini
- Tegura ingero nyinshi z'amazi
- Ongeraho ibipimo bitandukanye bya PAC
- Uruvange rwihuse
- Ongeraho PAM
- Uruvange ruhoro
- Reba imiterere y'amafi
- Pima ubushuhe nyuma yo guhagarara
Ibitekerezo by'ingenzi:
- Ingano y'urutoki
- Umuvuduko wo kugabanya umuvuduko
- Ubuziranenge bw'amazi
Igipimo cyiza gitanga:
- Amafarashi manini
- Gutuza vuba
- Amazi meza y'ikirenga
Amakosa akunze kubaho mu gihe uhuza PAC na PAM
Ndetse n'abakora akazi k'uburambe rimwe na rimwe bahura n'ibibazo.
Umwanzuro
Guhuza Polyaluminum Chloride na Polyacrylamide ni imwe mu ngamba nziza zo kunoza uburyo bwo gufunga no gufunga mu buryo bwo gutunganya amazi.
PAC igabanya ubukana bw'uduce duto duto duto binyuze mu kugabanya ingufu, mu gihe PAM yongera imiterere y'udusimba binyuze mu guhuza polymer. Iyo ikoreshejwe mu buryo bukwiye—PAC ya mbere, PAM ya kabiri—iyi miti ikora udusimba tunini kandi twinshi dutuma duhagarara vuba kandi tugatanga amazi meza.
Kugira ngo abakora ibikorwa byabo bagere ku musaruro mwiza, bagomba kwibanda kuri ibi bikurikira:
- Urukurikirane rw'ikoreshwa ry'umuti mu buryo bukwiye
- Kugenzura neza igipimo
- Gutegura igisubizo neza
- Uburyo bwiza bwo kuvanga
- Gupima ikigega kugira ngo harebwe uburyo ibintu bihinduka
Hamwe n'uburyo bwiza bwo gukora, PAC na PAM bishobora kunoza cyane imikorere myiza yo gutunganya amazi, imikorere yo gufunga imyanda, ndetse no kwizerana muri rusange.
