ʻO nā mea hana hoʻomaʻamaʻa ʻo MBR kahi inoa ʻē aʻe no ka bioreactor membrane. ʻO ia kahi mea hana hoʻomaʻemaʻe i hoʻohui ʻia me ka ʻenehana holomua. I kekahi mau papahana me nā koi effluent kiʻekiʻe a me ka mālama paʻa ʻana i nā mea haumia wai, hana maikaʻi loa ka bioreactor membrane. I kēia lā, e wehewehe ʻo Liding Environmental Protection, kahi mea hana ʻoihana hoʻomaʻemaʻe wai, e wehewehe iā ʻoe i kēia huahana me ka maikaʻi maikaʻi.
ʻO ka mea nui o nā lako hana hoʻomaʻemaʻe MBR ʻo ia ka membrane. Hoʻokaʻawale ʻia ʻo MBR i ʻekolu ʻano: ʻano waho, ʻano submerged a me nā ʻano composite. Wahi a inā pono ka oxygen i loko o ka reactor, ua māhele ʻia ʻo MBR i ke ʻano aerobic a me ke ʻano anaerobic. ʻO ka MBR Aerobic he manawa hoʻomaka pōkole a me ka hopena hoʻokuʻu wai maikaʻi, hiki ke hoʻokō i ka maʻamau o ka hoʻohana hou ʻana i ka wai, akā kiʻekiʻe ka hoʻopuka ʻana o ka sludge a nui ka hoʻohana ʻana i ka ikehu. Anaerobic MBR he haʻahaʻa ikehu hoʻohana, haʻahaʻa sludge hana, a me ka biogas hanauna, akā, lōʻihi ka manawa e hoʻomaka ai, a ʻaʻole maikaʻi ka hopena o ka lawe ʻana i nā mea haumia e like me ka MBR aerobic. Wahi a nā mea membrane like ʻole, hiki ke hoʻokaʻawale ʻia ka MBR i ka microfiltration membrane MBR, ultrafiltration membrane MBR a pēlā aku. ʻO nā mea membrane i hoʻohana maʻamau ʻia ma MBR he mau membrane microfiltration a me nā membrane ultrafiltration.
Wahi a ka pilina ma waena o nā modula membrane a me nā bioreactors, ua māhele ʻia ʻo MBR i ʻekolu mau ʻano: "aeration MBR", "separation MBR" a me "extraction MBR".
Ua kapa ʻia ʻo MBR Aerated Membrane Aerated Bioreactor (MABR). ʻOi aku ke ʻano o ka aeration o kēia ʻenehana ma mua o ka porous a i ʻole microporous nui. Hoʻohana ʻia ka membrane gas-permeable no ka aeration manuahi e hāʻawi i ka oxygen, a ʻoi aku ka kiʻekiʻe o ka hoʻohana ʻana o ka oxygen. ʻO ka biofilm ma ka membrane breathable e pili pono ana me ka wai, a hāʻawi ka membrane breathable i ka oxygen i nā microorganisms i hoʻopili ʻia iā ia, a hoʻohaʻahaʻa maikaʻi i nā mea haumia i ka wai.
Ua kapa ʻia ka ʻano hoʻokaʻawale MBR ʻo ke ʻano hoʻokaʻawale solid-wai MBR. Hoʻohui ia i ka ʻenehana hoʻokaʻawale membrane me ka ʻenehana lapaʻau kūlohelohe wai kuʻuna. Paʻa-wai hoʻokaʻawale maikaʻi. A no ka hoʻonui ʻana o ka ʻike o ka sludge i hana ʻia i loko o ka pahu aeration, hoʻomaikaʻi ʻia ka maikaʻi o nā hopena biochemical, a hoʻohaʻahaʻa hou ʻia nā mea haumia. Hoʻohana maʻamau ʻia ka MBR ʻano hoʻokaʻawale i nā papahana hoʻomaʻemaʻe wai ʻole MBR.
Hoʻohui ʻia ka MBR Extractive (EMBR) i ke kaʻina hana hoʻokaʻawale membrane me ka anaerobic digestion. Lawe nā membrane koho i nā mea ʻona mai ka wai ʻino. Hoʻololi nā microorganism anaerobic i nā mea olaola i loko o ka wai ʻino i methane, kahi kinoea ikehu, a hoʻololi i nā meaʻai (e like me ka nitrogen a me ka phosphorus) i loko o nā ʻano kemika hou aku, a laila e hoʻonui i ka hoʻihoʻi ʻana i nā kumuwaiwai mai ka wai ʻino.
