Choride ya polyaluminium:PAC muri make, izwi kandi nka aluminium chloride yibanze cyangwa hydroxyl aluminium chloride.
Ihame:binyuze mu bicuruzwa bya hydrolysis ya chloride ya polyaluminium cyangwa chloride polyaluminium, imvura ya colloidal mu miyoboro cyangwa imyanda irashirwaho vuba, byoroshye gutandukanya ibice binini byimvura.Imikorere:Isura n'imikorere ya PAC bifitanye isano na alkalinity, uburyo bwo gutegura, ibihumanye hamwe nibirimo alumina.
1, iyo alkalinity yamazi meza ya polyaluminium chloride iri murwego rwa 40% ~ 60%, ni amazi yumuhondo yoroheje yoroheje.Iyo alkaline irenze 60%, ihinduka buhoro buhoro ibara ritagira ibara.
2, iyo alkaline iri munsi ya 30%, chloride ikomeye ya polyaluminium ni lens.
3, iyo alkalinity iri murwego rwa 30% ~ 60%, ni ibintu bya colloidal.
4, iyo alkaline irenze 60%, ihinduka buhoro buhoro ikirahure cyangwa resin. Choride ya polyaluminium ikomeye ikozwe muri bauxite cyangwa minerval yibumba ni umuhondo cyangwa umukara.
Ibicuruzwa
Ibyiciro rusange
Ibirimo 22-24%:gutunganya ingoma yumusaruro, udafite isahani hamwe na kayunguruzo, ibikoresho bitangirika mumazi biri hejuru, nigiciro cyisoko ryibicuruzwa byinganda, cyane cyane bikoreshwa mugutunganya amazi mabi yinganda.
26% bikubiyemo:gutunganya ingoma yumusaruro, udafite isahani hamwe nayunguruzo, ibikoresho bidashonga amazi biri munsi ya 22-24%, iki gicuruzwa nigipimo cyigihugu cyurwego rwinganda, igiciro kiri hejuru gato, cyane cyane gikoreshwa mugutunganya amazi mabi yinganda.
28% bikubiyemo:ibi bifite ubwoko bubiri bwo gukama ingoma no kumisha spray, amazi akoresheje akayunguruzo ka plaque, amazi adashonga kurenza bibiri bya mbere byo hasi, nibicuruzwa bya PAC byo murwego rwohejuru, birashobora gukoreshwa mugutunganya imyanda mike hamwe no kwangiza ibiti byamazi.
Ibirimo 30%:hari ubwoko bubiri bwo kumisha ingoma no kumisha spray, amazi ya nyina akoresheje akayunguruzo ka plaque, ni mubicuruzwa byo mu rwego rwa PAC byo mu rwego rwo hejuru, bikoreshwa cyane cyane mu ruganda rw’amazi ya robine hamwe n’umuvuduko muke wo gutunganya amazi yo mu ngo.
32% bikubiyemo:ibi bikozwe no kumisha spray, bitandukanye nibindi bicuruzwa, iyi PAC igaragara ni umweru, ni isuku nyinshi idafite ferrous polyaluminium chloride, ikoreshwa cyane cyane munganda zikora imiti n’amavuta yo kwisiga, ni ibyiciro byibiribwa.
Polyacrylamide:bita PA M, bakunze kwita flocculant cyangwa coagulant
Ihame:Urunigi rwa molekile ya PAM hamwe no gutatanya icyiciro binyuze muburyo butandukanye bwubukanishi, umubiri, imiti nizindi ngaruka, icyiciro cyatatanye gihuza hamwe, kigakora umuyoboro, bityo bikazamura uruhare.
Imikorere:PAM ni ifu yera, gushonga mumazi, hafi yo kudashonga muri benzene, ether, lipide, acetone nizindi miti rusange yumuti rusange, igisubizo cyamazi ya polyacrylamide ni hafi ya flux viscous fluid, ni ibicuruzwa bidatera akaga, bidafite uburozi, bitangirika, bikomeye PAM ifite hygroscopicity, hygroscopicity yiyongera hamwe no kwiyongera kwa dogere ionic.
Ibicuruzwa
Ibyiciro rusange
PAM ukurikije ibiranga itsinda ryatandukanijwe igabanyijemo anionic polyacrylamide, cationic polyacrylamide na polyacrylamide itari ionic.Ionic polyacrylamide.
PAM:gukora sludge yakozwe nuburyo bwa biohimiki
Anionic PAM:umwanda hamwe nigitaka hamwe nuburyo bwiza, nkuruganda rwibyuma, uruganda rukora amashanyarazi, metallurgie, gukaraba amakara, gukuramo ivumbi nandi miyoboro, bigira ingaruka nziza
Nonionic PAM:kuri cationic na anionic bifite ingaruka nziza, ariko igiciro cyigiciro gihenze cyane, mubisanzwe ntabwo gikoreshwa cyane
Byombi byongeyeho gukoresha amabwiriza
Flocculation ni iki? Nyuma yo kongeramo coagulant mumazi mbisi, kuvanga byuzuye numubiri wamazi, imyanda myinshi ya colloid mumazi itakaza ituze, kandi uduce duto twa colloid udahungabana turagongana kandi tugahurira hamwe muri pisine, hanyuma tugakora floc ishobora gukurwaho nuburyo bwimvura.
Ibintu bigira uruhare runini
Inzira yo gukura kwa floc ninzira yo guhura no kugongana nuduce duto.
Ubwiza bwingaruka ziterwa na flocculation biterwa nibintu bibiri bikurikira:
1 ubushobozi bwibikoresho bya polymer byakozwe na coagulant hydrolysis yo gukora ikiraro cya adsorption ikiraro, kigenwa nimiterere ya coagulants
2 amahirwe yo kugongana nuduce duto nuburyo bwo kubigenzura kugirango bigongane kandi bifatika. Amasomo yubuvuzi bwamazi yizera ko kugirango hongerwe amahirwe yo kugongana, umuvuduko ukabije ugomba kwiyongera, kandi ingufu zikoreshwa mumubiri wamazi zigomba kuba byiyongereye mukongera umuvuduko wa gradient, ni ukuvuga, kongera umuvuduko w umuvuduko wa pisine ya flokculasiyo (inyongera: niba ibice byegeranye kandi bigakura vuba cyane muri flocculation, bizarimbuka. Hano haribibazo bibiri: gukura 1 kwibihingwa byihuse imbaraga zayo ni gucika intege, muburyo bwo gutemba byahuye nogosha gukomeye bizatuma ikiraro cya adsorption kiracibwa, ikiraro cyaciwe na adsorption ikiraro kiragoye gukomeza, bityo inzira ya flocculation nayo ni inzira ntarengwa, hamwe no gukura kwa floc, umuvuduko w umuvuduko ugomba kugabanuka, kugirango ibimera byakozwe bitoroha kumeneka 2 2 flc zimwe na zimwe zikura vuba cyane bizatuma ubuso bwamazi bwihariye bugabanuka cyane, reaction imwe ntabwo ari uduce duto duto twatakaje imiterere yimyitwarire, utwo duce duto nuduce twinshi turagongana; birashoboka ko byagabanutse cyane, biragoye kongera gukura, ibyo bice ntibishobora gusa kubigega byimyanda bigumana gusa, biragoye no kubigumana kugirango bishungurwe.)
Ongeraho ibisabwa
Mubyiciro byambere bya reaction yo kongeramo coagulant, birakenewe kongera amahirwe yo guhura numwanda uko bishoboka kwose, kongera umuvuduko cyangwa umuvuduko. Biterwa no kugongana kwamazi no gufata isahani hamwe no gutemba kwamazi hagati kuzinga isahani kugirango wongere umuvuduko, kugirango ibice byamazi bigongane amahirwe yiyongere, kugirango flc yegeranye.Kandi no gutinda gutinda, kugirango ugabanye umuvuduko ukabije, ushobora kubona flokculation nziza, ingaruka yimvura.
Ongeraho ibikoresho:ibikoresho byibiyobyabwenge, ikigega kibika ibiyobyabwenge, dose stirrer, pompe ikoreshwa nibikoresho byo gupima.Bifite ibikoresho byo gukoresha uburyo
PAC, PAM itanga intumbero (yakuwe mu gikapu cyo gupakira ibiyobyabwenge hanyuma ikongerwamo ikigega cyo gusesa) PAC na PAM itanga ibitekerezo Ukurikije ubunararibonye: PAC yo gusenya PAC yibanda kuri 5% -10%, PAM yibanze kuri 0.1% -0.3%, hejuru yamakuru ugereranije nubuziranenge, ni ukuvuga, buri kibe cyamazi PAC 50-100kg, PAM 1-3kg. Ubu bwitonzi buri hejuru cyane, ubushobozi bwo gusesa PAM bugarukira, bukeneye kubyutsa umuvuduko ukabije kugirango bicike burundu.Mu mpeshyi, Ihagarikwa rya PAM rishobora kwiyongera neza kugeza kuri 0.3-0.5% .Fata ubwinshi bwa PAC yo gusesa bwa 10%, PAM yo gushonga kwa 0.5%, hanyuma amazi ya cubic yose yashonga PAC100kg, PAM5kg, uhindure pompe ya diaphragm yatemba, ukurikije metero kibe 1 / Kubara amasaha 24, ni ukuvuga, Q = litiro 42 / isaha, irashobora kugera kubikorwa byiza byo gutunganya imyanda.PAC, PAM itunganya umwanda wamazi (ushonga mumazi yumwimerere) Igipimo cyo gutunganya imyanda muri rusange ni PAC 50-100ppm, PAM 2-5ppm, ppm igice ni miriyoni imwe, bityo gihinduka garama 50-100 za PAC kuri toni yimyanda, Garama 2-5 za PAM, birasabwa ko muri rusange ukurikije iki kigeragezo cya dosiye. Niba ubushobozi bwo gutunganya imyanda ya buri munsi ari metero kibe 2000, kwibumbira hamwe kwa PAC ukurikije 50ppm, kwibumbira hamwe kwa PAM ukurikije kubara 2ppm, hanyuma buri munsi dosiye ya PAC ni 100kg, dosiye ya PAM ni 4kg.Ibipimo byavuzwe haruguru bibarwa ukurikije uburambe rusange, ibipimo byihariye hamwe nubunini bwa dosiye bigomba gushingira kubushakashatsi bwihariye bwubwiza bwamazi.Kubara agaciro kashyizweho muri metero ya pompe ya pompe
Nyuma yo kongeramo umukozi mumazi cyangwa umwanda, bigomba kuvangwa neza.Igihe cyo kuvanga ni amasegonda 10-30, mubisanzwe ntabwo kirenze iminota 2.Igipimo cyihariye cya agent hamwe nubushuhe bwibice bya colloidal, ibintu byahagaritswe mumazi cyangwa umwanda, ibikoresho bya kamere hamwe nubuvuzi bifite isano ikomeye, dosiye yo kuvura slegge kuri bamwe, dosiye nziza iboneka binyuze mubushakashatsi bwinshi. Dukurikije icyerekezo cyiza cya dosiye (ppm1 kugirango wongere concentration) hamwe namazi atemba (t / h) hamwe nuburyo bwo gukemura igisubizo (ppm2 yo kwitegura kwibanda), birashobora kubarwa kuri pose ya pompe yerekana agaciro (LPM) .Igiciro cyerekana agaciro gukuramo pompe yamashanyarazi (LPM) = gutemba kwamazi (t / h) / 60 × PPM1 kugirango wongere ibitekerezo / PPM2 yo gutegura.
Icyitonderwa: ppm ni miriyoni imwe; gukuramo pompe yamashanyarazi yibiciro, LPM ni litiro / umunota; GPM ni gallons / umunota
