Abstract: mubijyanye n’amazi y’imyanda no gutunganya ibisigazwa by’imyanda, PAC na PAM byakoreshejwe cyane nka flocculants hamwe nubufasha bwa coagulant. Uru rupapuro rugaragaza ingaruka zikoreshwa hamwe nubushakashatsi bwa pac-pam mubice bitandukanye, bisobanura muri make imyumvire n'ibitekerezo by'abashakashatsi batandukanye ku guhuza pac-pam, kandi isesengura byimazeyo ibisabwa ibisabwa n'amahame ya pac-pam mubihe bitandukanye byubushakashatsi. n'imiterere y'umurima. Ukurikije ibikubiye hamwe nisesengura ryibisubizo byakozwe, iyi mpapuro yerekana ihame ryimbere rya pac-pam ikoreshwa mubikorwa bitandukanye byakazi, ikanagaragaza ko guhuza PAC na PAM nabyo bifite inenge, kandi uburyo bwo kubikoresha hamwe na dosiye bigomba gufatwa hakurikijwe ibihe byihariye.
Ijambo ryibanze: polyaluminium chloride; Polyacrylamide; Gutunganya amazi; Flocculation
0 Intangiriro
Mu nganda, gukoresha hamwe na chloride ya polyaluminium (PAC) na polyacrylamide (PAM) mu gutunganya amazi y’imyanda n’imyanda isa nayo byashizeho urunana rw’ikoranabuhanga rukuze, ariko uburyo bw’ibikorwa bihuriweho ntibusobanutse, kandi igipimo cya dosiye ku mikorere itandukanye muri imirima itandukanye nayo iratandukanye.
Uru rupapuro rusesengura byimazeyo umubare munini wibitabo byingirakamaro mugihugu ndetse no hanze yarwo, ruvuga muri make uburyo bwo guhuza PAC na PAC, kandi rukora imibare yuzuye kumyanzuro itandukanye ifatika hamwe ningaruka nyazo za PAC na PAM mubikorwa bitandukanye, bifite akamaro kayobora kubushakashatsi burenzeho mubice bifitanye isano.
1. Gukoresha murugo ubushakashatsi bwubushakashatsi bwa pac-pam
Ingaruka zifatika za PAC na PAM zikoreshwa mubice byose byubuzima, ariko dosiye nuburyo bwo kuvura buratandukanye kubikorwa bitandukanye nibikorwa byubuvuzi.
1.1 imyanda yo mu ngo hamwe n’amazi ya komini
Zhao Yueyang (2013) n'abandi bagerageje ingaruka za coagulation ya PAM nk'imfashanyo ya coagulant kuri PAC na PAFC bakoresheje uburyo bwo kwipimisha mu nzu. Ubushakashatsi bwerekanye ko coagulation ya PAC nyuma ya PAM coagulation yariyongereye cyane.
Wang Mutong (2010) n'abandi biga ku ngaruka zo kuvura PAC + PA ku miyoboro yo mu ngo yo mu mujyi, baniga uburyo bwo gukuraho COD n'ibindi bipimo binyuze mu bushakashatsi bwa orthogonal.
Lin yingzi (2014) n'abandi. Yize ingaruka nziza ya coagulation ya PAC na PAM kuri algae muruganda rutunganya amazi. Yang Hongmei (2017) n'abandi. Yize ingaruka zo kuvura ikoreshwa hamwe kumazi ya kimchi, hanyuma urebe ko agaciro ka pH ari 6.
Fu peiqian (2008) n'abandi. Yize ku ngaruka za flocculant ikoreshwa mugukoresha amazi. Mugupima ingaruka zo gukuraho umwanda nkumuvurungano, TP, COD na fosifate mubitegererezo byamazi, usanga flocculant yibintu bifite ingaruka nziza zo kuvanaho ubwoko bwose bwanduye.
Cao Longtian (2012) n'abandi bakoresheje uburyo bwo guhuza ibimera kugira ngo bakemure ibibazo by’umuvuduko ukabije w’umuvuduko, ibimera byoroheje kandi bigoye kurohama muri gahunda yo gutunganya amazi mu majyaruguru y’Ubushinwa kubera ubushyuhe buke mu gihe cy'itumba.
Liu Hao (2015) n'abandi. Yize ku ngaruka zo kuvura flocculant yibintu bigora kumyanda igoye no kugabanuka kwimyanda ihumanya imyanda yo murugo, ugasanga kongeramo umubare munini wa PAM mugihe wongeyeho PAM na PAC bishobora guteza imbere ingaruka zanyuma zo kuvura.
1.2 gucapa no gusiga irangi amazi mabi hamwe nogukora impapuro
Zhang Lanhe (2015) n'abandi. Yize ku ngaruka zo guhuza chitosani (CTS) na coagulant mu gutunganya amazi mabi y’impapuro, asanga ari byiza kongeramo chitosani
Igipimo cyo gukuraho COD n’umuvurungano cyiyongereyeho 13.2% na 5.9%.
Xie Lin (2010) yize ku ngaruka za PAC na PAM hamwe no gutunganya amazi mabi.
Liu Zhiqiang (2013) nabandi bakoresheje ubwabo PAC na PAC yibumbiye hamwe na ultrasonic bavura amazi yo gucapa no gusiga irangi. Hanzuwe ko mugihe agaciro ka pH kari hagati ya 11 na 13, PAC yabanje kongerwamo hanyuma ikangurwa muminota 2, hanyuma PAC yongewemo hanyuma ikangurwa muminota 3, ingaruka zo kuvura nizo nziza.
Zhou Danni (2016) n'abandi bize ubushakashatsi ku ngaruka zo kuvura PAC + PAM ku myanda yo mu ngo, bagereranya ingaruka zo kuvura umuvuduko w’ibinyabuzima na antidote y’ibinyabuzima, basanga PAC + PAM yari nziza kuruta uburyo bwo kuvura ibinyabuzima mu gukuramo amavuta, ariko PAC + PAM yari nziza cyane kuruta uburyo bwo kuvura ibinyabuzima muburozi bwamazi.
Wang Zhizhi (2014) n'abandi. Yize uburyo bwo kuvura uburyo bwo gutunganya impapuro zo hagati yo hagati ya PAC + PAM coagulation mubice byuburyo. Iyo igipimo cya PAC ari 250 mg / L, igipimo cya PAM ni 0,7 mg / L, kandi agaciro ka pH ntikabogamye, igipimo cyo gukuraho COD kigera kuri 68%.
Zuo Weiyuan (2018) nabandi barize kandi bagereranya ingaruka zivanze na flocculation ya Fe3O4 / PAC / PAM. Ikizamini cyerekana ko iyo igipimo cya bitatu ari 1: 2: 1, ingaruka zo kuvura gucapa no gusiga amarangi amazi meza.
LV sining (2010) n'abandi. Yize ingaruka zo kuvura PAC + PAM ikomatanya kumazi yo hagati. Ubushakashatsi bwerekana ko ingaruka ziterwa na flocculation aribyiza mubidukikije bya aside (pH 5). Igipimo cya PAC ni 1200 mg / L, urugero rwa PAM ni 120 mg / L, naho igipimo cyo gukuraho code kirenga 60%.
1.3 Amazi yimyanda yamakara no gutunganya amazi mabi
Yang Lei (2013) n'abandi. Yize ku ngaruka ziterwa na PAC + PAM mu gutunganya amazi y’inganda z’amakara, ugereranije n’imyanda isigaye munsi y’ibipimo bitandukanye, kandi itanga urugero rwahinduwe na PAM ukurikije imivurungano itandukanye ya mbere.
Fang Xiaoling (2014) nabandi bagereranije ingaruka ya coagulation ya PAC + Chi na PAC + PAM kumazi y’inganda. Bashoje bavuga ko PAC + Chi yagize ingaruka nziza zo gukwirakwiza no gukuraho COD neza. Ibisubizo byubushakashatsi byerekanaga ko igihe cyiza cyo gukurura cyari 10 min naho agaciro ka pH kari 7.
Deng Lei (2017) n'abandi. Yize ku ngaruka za flocculation ya PAC + PAM ku gucukura amazi y’amazi, kandi igipimo cyo gukuraho COD cyageze kuri 80%.
Wu Jinhua (2017) n'abandi. Yize uburyo bwo gutunganya amazi mabi yamakara akoresheje coagulation. PAC ni 2 g / L na PAM ni 1 mg / L. ubushakashatsi bwerekana ko agaciro ka pH ari 8.
Guo Jinling (2009) n'abandi. Yize ku ngaruka zo gutunganya amazi ya flocculation yibumbiye hamwe atekereza ko ingaruka zo kuyikuramo ari nziza mugihe dosiye ya PAC yari 24 mg / L na PAM yari 0.3 mg / L.
Lin Lu (2015) n'abandi. Yize ku ngaruka za flocculation ziterwa na pac-pam kumavuta ya emulisile arimo amazi mabi mubihe bitandukanye, kandi agereranya ingaruka za flocculant imwe. Igipimo cyanyuma ni: PAC 30 mg / L, pam6 mg / L, ubushyuhe bwibidukikije 40 ℃, pH idafite aho ibogamiye nigihe cyo gutembera muminota irenga 30. Mubihe byiza cyane, uburyo bwo gukuraho COD bugera kuri 85%.
2 umwanzuro n'ibitekerezo
Ihuriro rya polyaluminium chloride (PAC) na polyacrylamide (PAM) ryakoreshejwe cyane mubice byose byubuzima. Ifite ubushobozi bukomeye mubijyanye n’amazi y’amazi no gutunganya imyanda, kandi agaciro kayo mu nganda kagomba kurushaho gushakishwa.
Uburyo bwo guhuza PAC na PAM ahanini biterwa nubworoherane bwiza bwurunigi rwa PAM macromolecular, buhujwe na Al3 + muri PAC na - O muri PAM kugirango habeho imiterere ihamye. Imiterere y'urusobekerane rushobora guhisha ibindi byanduye nkibice bikomeye hamwe nigitonyanga cyamavuta, bityo bigira ingaruka nziza zo gutunganya amazi mabi hamwe nubwoko bwinshi bwanduye, cyane cyane kubana namavuta namazi.
Mugihe kimwe, guhuza PAC na PAM nabyo bifite inenge. Amazi yibigize flocculite ni menshi, kandi imiterere yimbere yimbere iganisha kubisabwa kugirango bivurwe kabiri. Kubwibyo, iterambere ryiterambere rya PAC rifatanije na PAM riracyafite ibibazo nibibazo.
