Imishini yokwelapha indle ye-MBR ingenye igama le-membrane bioreactor.imishini yokuhlanza indle ehlanganisiwengobuchwepheshe obuthuthukisiwe. Kweminye imisebenzi enezidingo eziphezulu zokungcola kanye nokulawulwa okuqinile kokungcola kwamanzi, i-membrane bioreactor isebenza kahle kakhulu. Namuhla, i-Liding Environmental Protection, umkhiqizi wemishini yokwelapha indle ochwepheshe, izokuchazela lo mkhiqizo ngempumelelo evelele.
Ingxenye eyinhloko yeImishini yokuhlanza indle ye-MBRyi-membrane. I-MBR ihlukaniswe ngezinhlobo ezintathu: uhlobo lwangaphandle, uhlobo olucwiliswe emanzini kanye nohlobo oluhlanganisiwe. Ngokuya ngokuthi i-oxygen iyadingeka yini ku-reactor, i-MBR ihlukaniswe ngohlobo lwe-aerobic kanye nohlobo lwe-anaerobic. I-Aerobic MBR inesikhathi esifushane sokuqala kanye nomphumela omuhle wokukhipha amanzi, okungahlangabezana nezinga lokusetshenziswa kabusha kwamanzi, kodwa umphumela wodaka uphezulu futhi ukusetshenziswa kwamandla kukhulu. I-Anaerobic MBR inokusetshenziswa kwamandla okuphansi, ukukhiqizwa kodaka okuphansi, kanye nokukhiqizwa kwe-biogas, kodwa kuthatha isikhathi eside ukuqala, futhi umphumela wokususa ukungcola awumuhle njenge-aerobic MBR. Ngokwezinto ezihlukene ze-membrane, i-MBR ingahlukaniswa ibe yi-microfiltration membrane MBR, i-ultrafiltration membrane MBR njalo njalo. Izinto ze-membrane ezivame ukusetshenziswa ku-MBR yi-microfiltration membranes kanye ne-ultrafiltration membranes.
Ngokusho kokuxhumana phakathi kwamamojula e-membrane nama-bioreactor, i-MBR ihlukaniswe ngezinhlobo ezintathu: "i-aeration MBR", "i-separation MBR" kanye ne-"extraction MBR".
I-MBR evuvukele ibizwa nangokuthi i-Membrane Aerated Bioreactor (MABR). Indlela yokungenisa umoya yalobu buchwepheshe ingcono kune-bubble enkulu evuvukele noma enezimbobo ezincane. I-membrane engena ngegesi isetshenziselwa ukungenisa umoya ongenayo amabhamuza ukuze inikeze umoya-mpilo, futhi izinga lokusetshenziswa komoya-mpilo liphezulu. I-biofilm e-membrane evuvukele ithintana ngokuphelele nendle, futhi i-membrane evuvukelekayo inikeza umoya-mpilo kuma-microorganisms anamathele kuyo, futhi iyonakalisa ngempumelelo ukungcola emanzini.
Uhlobo lwe-MBR lokuhlukaniswa lubizwa nangokuthi uhlobo lwe-MBR lokuhlukaniswa okuqinile nolwelwesi. Luhlanganisa ubuchwepheshe bokuhlukanisa i-membrane nobuchwepheshe bendabuko bokwelashwa kwamanzi amdaka. Ukusebenza kahle kokuhlukanisa okuqinile nolwelwesi. Futhi ngenxa yokuthi okuqukethwe kodaka olusebenzayo ethangini lokungenisa umoya kuyanda, ukusebenza kahle kwemiphumela yamakhemikhali kuyathuthuka, futhi ukungcola kwezinto eziphilayo kuyawohloka. Uhlobo lwe-MBR lokuhlukaniswa luvame ukusetshenziswa kumaphrojekthi okwelapha indle ye-MBR.
I-Extractive MBR (EMBR) ihlanganisa inqubo yokuhlukanisa ulwelwesi nokugaya okungasebenzisi i-anaerobic. Ulwelwesi olukhethiwe lukhipha amakhemikhali anobuthi emanzini angcolile. Amagciwane angasebenzi aguqula izinto eziphilayo emanzini angcolile abe yi-methane, igesi yamandla, bese eguqula izakhamzimba (njenge-nitrogen ne-phosphorus) zibe izinhlobo eziningi zamakhemikhali, ngaleyo ndlela kwandisa ukubuyiswa kwemithombo emanzini angcolile.
