Ibyiza bya polyaluminium chloride ikora neza mugutunganya amazi mabi

Hamwe no kwihutisha inganda, gusohora imyanda byabaye ikibazo gikomeye mu kurengera ibidukikije ku isi. Intandaro yo gutunganya imyanda iri mu guhitamo no gukoreshaflocculantsmugikorwa cyo kwezwa. Mu myaka yashize, chloride ikora neza cyane (PAC), nka flocculant ikomeye, yagiye ihinduka "ibicuruzwa byinyenyeri" mu nganda zitunganya imyanda kubera imikorere myiza kandi ifite amahirwe menshi yo kuyashyira mu bikorwa.

Choride ya polyaluminium ni polymer organique idafite imbaraga zikomeye za flocculation. Iraboneka na polymerisation reaction ya aluminium chloride na hydroxide ya aluminium mubihe byihariye. Ugereranije na flucculants ya aluminiyumu gakondo (nka sulfate ya aluminium, umunyu wa aluminiyumu, n'ibindi), chloride ya polyaluminium ikora neza ifite ubushobozi bukomeye bwo gukuraho umwanda, cyane cyane iyo uhuye n’umuvurungano mwinshi hamwe n’umwanda mwinshi w’amavuta. Imikorere iragaragara cyane iyo igeze ku bwiza bwamazi. Yakoreshejwe henshi mubice byinshi nko gutunganya imyanda ya komini, gutunganya imyanda mvaruganda, no gutunganya imyanda yo murugo.

Ibyiza bya chloride nziza cyane

1. Ingaruka ya flocculation iratangaje

Chloride ikora neza cyane irashobora gukora vuba umubare munini wibintu byiza mumazi, bityo bikamenyekanisha neza ibintu byahagaritswe, ibintu bya colloidal hamwe na mikorobe mikorobe mumazi. Irashobora kwihuta adsorb no gukuraho ibice byahagaritswe, amavuta, ibyuma biremereye ion nibindi bihumanya mumazi. Cyane cyane iyo uhuye nubuziranenge bwamazi, ingaruka ziruta kure cyane imyunyu ngugu ya aluminium. Mu gutunganya imyanda, chloride ikora neza cyane ya chloride irashobora kongera umuvuduko wo gutuza wikigega cyimyanda mugihe gito, bityo bikagabanya cyane uburyo bwo gutunganya imyanda.

2.Ibice byinshi byo gusaba

Choride ya polyaluminium ikora nezaIrashobora guhuza nuburyo butandukanye bwamazi meza, harimo amazi mabi cyane, umwanda mwinshi wamavuta, amazi arimo ibyuma biremereye, hamwe nubushyuhe buke bwo mumazi mabi, byerekana guhuza n'imiterere. Irashobora gukuraho neza ibintu byinshi byahagaritswe hamwe n’imyanda ihumanya mu mazi, kandi irashobora gukoreshwa cyane mugutunganya imyanda mubice bitandukanye nkubuyobozi bwa komini, inganda, nubucukuzi. Kurugero, mugutunganya imyanda yo murugo, amazi mabi yamazi, amazi mabi ya metallurgiki, amazi mabi yinganda zibiribwa nibindi bintu, chloride ya polyaluminium ikora neza irashobora kugera kubisubizo byiza byo gutunganya.

3. Igipimo gito, gukora neza no kuzigama ingufu

Choride ikora neza cyane ya polyaluminium yashizweho kugirango igere kuri dosiye nkeya ningaruka nziza ya flocculation. Igipimo cya turbidite nkeya ni 25-40% ya sulfate ya aluminium, naho dosiye yo guhindagurika cyane ni 10-25% ya sulfate ya aluminium. Ibi ntibigabanya gusa ikiguzi cyo gukoresha imiti, ahubwo binagabanya gukoresha ingufu hamwe nigitonyanga mugikorwa cyo gutunganya imyanda. Kubera ibisigazwa bya aluminiyumu nkeya, bigabanya umwanda wa kabiri w’amazi kandi bigabanya cyane ikiguzi rusange cyo gutunganya imyanda. Kubwibyo, byahindutse igikoresho cyingenzi cyo kuzigama ibiciro no kunoza imikorere mubikorwa bifatika.

4. Ibidukikije byangiza ibidukikije

Ikoreshwa rya chloride ya polyaluminium ikora neza ntigira ingaruka nke kubidukikije hamwe na aluminiyumu nkeya. Ugereranije n’ibindi binyabuzima bya chimique, polyaluminium chloride ifite umutekano kandi ntigire ingaruka nke kuri pH na TA yimyanda, bityo rero imiti ikenera imiti ihindura pH na TA iragabanuka. Cyane cyane mumishinga minini yo gutunganya imyanda no kurengera ibidukikije, yahindutse icyatsi kibisi kandi cyangiza ibidukikije.

5. Birakwiriye ubushyuhe buke no gutunganya amazi menshi

Gutunganya amazi mugihe cy'ubushyuhe buke nikibazo gisanzwe. Cyane cyane mu gihe cyubukonje, imikorere ya flocculants nyinshi izagabanuka cyane. Nyamara, chloride ikora cyane ya polyaluminium irashobora gukomeza kugumana ingaruka nyinshi ziterwa nubushyuhe buke. Byongeye kandi, iyo umuvuduko mwinshi wamazi ari mwinshi, PAC irerekana kandi ubushobozi bukomeye bwo gutunganya kandi irashobora gukuraho neza ibice byahagaritswe nibintu bya colloidal mumazi. Ku mazi afite umwanda mwinshi wa peteroli, chloride ya polyaluminium ikora neza nayo igira ingaruka nziza cyane.

6. Guhuza na pH zitandukanye zitandukanye

Choride ya polyaluminium ikora neza ifite imbaraga zo guhuza n’imihindagurikire y’amazi pH kandi irashobora gukora neza muburyo bugari bwa pH. Muri rusange, PAC irashobora gukomeza kugira ingaruka nziza mumazi afite amazi yo hasi (acide) cyangwa arenze (alkaline) pH, ibyo bikaba byongera uburyo bukoreshwa mubihe bitandukanye byamazi meza. 5.0-9.0 vs 5.5-7.5

7. Kunoza imikorere yubutaka no kugabanya ingano ya silige

Choride ikora neza cyane ya polyaluminium ifasha kwihutisha gutuza ibice bikomeye mumyanda kandi ikanoza imikorere yimikorere yikigega cyimitsi itezimbere ubwinshi bwimiterere yabantu. Byongeye kandi, kubera urwego rwo hejuru rwa polymerisiyumu ya chloride ya polyaluminium ikora neza, flocs zakozwe zirakomera kandi zigatuza vuba, bityo bikagabanya ubwinshi bwumwanda wakozwe. Ibi bifite akamaro kanini kubuvuzi bwakurikiyeho no kujugunya, kandi birashobora kugabanya ikiguzi ningorane zo kuvura imyanda.

Gukoresha ingero za polyaluminium chloride ikora neza mugutunganya amazi mabi

1. Gutunganya imyanda yo mu mijyi

Mu rwego rwo gutunganya imyanda y’amakomine, chloride ikora neza cyane irashobora gukoreshwa cyane mugutegura no gutunganya icyiciro cya kabiri cy’ibihingwa by’amazi. Irashobora gukuraho neza ibintu byahagaritswe, ibintu byitwa colloidal, bagiteri nizindi mikorobe mu mazi, kuzamura ubwiza bw’amazi, kandi bigatanga isoko y’amazi meza yo kuvura ibinyabuzima nyuma. PAC ibaye imwe mumigezi nyamukuru yibimera bitunganya imyanda mumijyi myinshi murugo ndetse no mumahanga.

2.Gutunganya amazi mabi yinganda

Mu rwego rwo gutunganya amazi mabi yinganda, chloride ya polyaluminium ikora neza nayo ikoreshwa cyane. Ifite ingaruka nziza zo gutunganya amazi mabi yinganda kuva gucapa no gusiga irangi, gukora impapuro, uruhu, amashanyarazi nizindi nganda, kandi irashobora gukuraho neza umwanda nkamabara, COD na BOD. Kurugero, mubyuma, ingufu z'amashanyarazi, inganda zikora imiti, gukora impapuro, gutunganya ibiryo nizindi nganda, PAC irashobora gufasha gukuraho ibyuma biremereye, irangi ryamavuta, uduce twahagaritswe nibindi byangiza mumazi. Cyane cyane mugihe cyo gutunganya amazi mabi yamavuta, PAC yerekanye ubushobozi bwayo bwiza bwo kuvanaho amavuta kandi irashobora kugabanya cyane amavuta yibintu byamazi.

3. Gucukura amabuye y'agaciro

Mu rwego rwo gutunganya imyanda y’amazi, chloride ya polyaluminium ikora neza irashobora gukuraho neza amabuye y’amabuye, imyanda n’ibindi bintu byahagaritswe mu mazi, bigatanga inkunga yo gutunganya amazi no gusana ibidukikije mu bucukuzi bw’amabuye y'agaciro. Kubera ko ubwiza bw’amazi mu bucukuzi bugoye kandi ubusanzwe burimo ibintu byinshi byahagaritswe hamwe n’ibyuma biremereye, imikorere myiza ya chloride polyaluminium ikora neza cyane igaragara cyane muri ubu buryo bwo gutunganya amazi mabi.

Muri rusange,chloride ikora neza cyane, nka flocculant nziza yo gutunganya imyanda, ifite ibyiza bya tekiniki nibidukikije. Cyane cyane kubijyanye n’umuvuduko mwinshi, ubwiza bw’amazi, hamwe n’umwanda mwinshi w’amavuta, birashobora kugera ku ngaruka nziza zo kuvura.
