Ni izihe polima zikoreshwa nk'imiti igabanya ubushyuhe?

Intambwe y'ingenzi mu gikorwa cyo gutunganya amazi yanduye ni ugufatana no gutuza kw'ibintu bikomeye bihagaze, igikorwa gishingiye cyane cyane ku binyabutabire byitwaimiti igabanya ubushyuheMuri ibi, polimeri zigira uruhare runini, bityo PAM, polyamines. Iyi nkuru izasuzuma ibijyanye n'imiti isanzwe ya polimeri, ikoreshwa rya polimeri nk'imiti ikoreshwa mu gutunganya amazi yanduye, n'imikorere yayo.

Ni ibihe bikunze gukoreshwaibikoresho byo mu bwoko bwa polima?

Ama-flocculant akoreshwa cyane muri polymer arimo cationic polymers, anionic polymers na non-ionic polymers. Izi polymers zishobora kuboneka hakoreshejwe uburyo butandukanye bwo gukora kandi zifite imiterere itandukanye ya cationic na branches. Mu bikorwa bifatika, ni ngombwa guhitamo polymer flocculants zikwiye hakurikijwe imiterere yihariye y'amazi yanduye kugira ngo haboneke ingaruka nziza zo kuyatunganya. PAM, polyDADMAC, ikoreshwa cyane mu gutunganya amazi yanduye mu nganda. Polyacrylamide niyo flocculant ikoreshwa cyane ku isi. Izi polymers zishobora gushonga mu mazi ni synthetic kandi zishobora gukorerwa ku buryo bwihariye hakoreshejwe uburemere butandukanye bwa molekile, viscosities, charge degree zitandukanye, imiterere itandukanye nk'uduce duto, emulsions, nibindi. PolyDADMAC ikoreshwa cyane mu mazi ya robine, flocculation y'amazi mabi, amazi y'imyanda, inganda z'impapuro n'inganda zicapa n'izisiga amarangi.

Ikoreshwa ryaimiti igabanya ubukana bw'amazi mabi mu gutunganya amazi yanduye

Intego nyamukuru yo gutunganya amazi yanduye ni ugukuraho imyanda nk'ibintu bikomeye biva mu mazi, ibintu by'umwimerere byashongeshejwe n'uduce twa colloidal mu mazi kugira ngo amazi arusheho kuba meza. Muri iki gikorwa, uduce twa flocculants tugira uruhare runini. Mu gukoresha uduce twa flocculants, uduce duto n'ibintu bya colloidal mu mazi bishobora gutuma bihurira mu duce duto, dushobora gukurwaho byoroshye hakoreshejwe uburyo bwo kuyasukura cyangwa kuyayungurura. Ibi ntibishobora kongera ubwiza bw'amazi gusa, ahubwo binanongera imikorere myiza yo kuyasukura no kugabanya ikiguzi cyo kuyasukura.

Kuki polymers zishobora gukora flocculants?

Polymer zishobora gukoreshwa nk'ibice bito bito bitewe ahanini n'uburemere bwabyo bwinshi bwa molekile n'imiterere yabyo ifite amashami menshi. Iyi miterere ituma polymeri irushaho kwinjirira ku duce duto, igakora uduce duto dushobora kwimuka vuba. Byongeye kandi, polymeri zishobora gukuraho electrostatic repulsion hagati y'uduce duto binyuze mu kugabanya ingufu, bigatuma uduce kwegerana no kwishyira hamwe.

Uburyo polymer zikora mu gutunganya amazi yanduye

Uburyo polimeri zikora nk'ibice bito bishobora kugabanywamo ibice bitatu: gukurura ingufu, gukurura ingufu no gufata imbunda. Ubwa mbere, polimeri ikuraho gukurura ingufu hagati y'ibice bito binyuze mu gukurura ingufu, bigatuma ibice biregera. Hanyuma polimeri ihuza ibice bito kugira ngo bikore ibice binini binyuze mu gukurura ingufu. Amaherezo, ibi bice birushaho guhurizwa hamwe no guturwa mu mazi binyuze mu gukurura imbunda.

Ibintu bigira ingaruka ku mikorere ya polymers mu gutunganya amazi yanduye

Hari ibintu byinshi bigira ingaruka ku mikorere myiza ya polymer mu gutunganya amazi yanduye, harimo ubwoko bwa polymer, ingano, pH, ubushyuhe, umuvuduko wo gukangura, nibindi. Muri byo, ubwoko bwa polymer n'ingano ni kimwe mu bintu by'ingenzi. Ubwoko butandukanye bwa polymer bufite imiterere itandukanye yo gushyushya n'ibipimo by'uburemere bwa molekile, bityo ni ngombwa guhitamo ubwoko bwa polymer bukwiye n'ingano y'amazi yanduye atandukanye kugira ngo haboneke ingaruka nziza zo kuyatunganya. Byongeye kandi, ibintu nk'agaciro ka pH, ubushyuhe, n'umuvuduko wo gukangura nabyo bigira ingaruka ku mikorere myiza yo kuyatunganya, kandi imiterere myiza igomba kugenwa binyuze mu igerageza.

Polymers zigira uruhare runini mu gutunganya amazi yanduye. Gusobanukirwa neza uburyo polymers zikora n'ibintu bigira ingaruka kuri zo bishobora gutanga ubufasha bw'ingenzi mu by'imitekerereze n'ubuyobozi bufatika mu kunoza uburyo bwo gutunganya amazi yanduye no kunoza imikorere myiza y'ubuvuzi. Mu gihe kizaza, hamwe no kunoza ibikenewe mu kubungabunga ibidukikije no gukomeza gutera imbere mu bumenyi n'ikoranabuhanga, bikekwa ko ikoreshwa rya polymers mu gutunganya amazi yanduye rizarushaho kuba rinini kandi ryimbitse.
