MBR dej phwj kho khoom siv yog lwm lub npe rau membrane bioreactor. Nws yog cov khoom siv kho dej phwj sib xyaw nrog cov thev naus laus zis siab heev. Hauv qee qhov dej num uas yuav tsum tau muaj dej ntau thiab kev tswj xyuas nruj ntawm cov dej paug, membrane bioreactor ua tau zoo tshwj xeeb. Niaj hnub no, Liding Environmental Protection, lub chaw tsim khoom siv dej phwj tuaj, yuav piav qhia rau koj cov khoom no nrog kev ua haujlwm zoo.
Cov khoom tseem ceeb ntawm MBR cov khoom siv dej phwj tuaj yog cov membrane. MBR muab faib ua peb hom: hom sab nraud, hom submerged thiab hom sib xyaw. Raws li seb puas xav tau oxygen hauv lub reactor, MBR muab faib ua aerobic type thiab anaerobic type. Aerobic MBR muaj lub sijhawm pib luv luv thiab cov dej tawm zoo, uas tuaj yeem ua tau raws li cov qauv siv dej rov qab, tab sis cov sludge tso tawm yog siab thiab siv zog loj. Anaerobic MBR muaj tsawg zog noj, tsawg sludge ntau lawm, thiab biogas tiam, tab sis nws yuav siv sij hawm ntev los pib, thiab kev tshem tawm cov pa phem tsis zoo li aerobic MBR. Raws li cov ntaub ntawv sib txawv, MBR tuaj yeem muab faib ua microfiltration membrane MBR, ultrafiltration membrane MBR thiab lwm yam. Membrane cov ntaub ntawv feem ntau siv hauv MBR yog microfiltration membranes thiab ultrafiltration membranes.
Raws li kev sib cuam tshuam ntawm membrane modules thiab bioreactors, MBR muab faib ua peb hom: "aeration MBR", "separation MBR" thiab "extraction MBR".
Aerated MBR tseem hu ua Membrane Aerated Bioreactor (MABR). Txoj kev aeration ntawm cov cuab yeej no yog superior rau cov tsoos ntxeem tau los yog microporous loj npuas aeration. Cov pa roj-permeable membrane yog siv rau cov npuas-dawb aeration los muab cov pa oxygen, thiab kev siv cov pa oxygen siab heev. Lub biofilm ntawm lub breathable membrane yog nyob rau hauv tag nrho kev sib cuag nrog cov dej phwj tuaj, thiab lub breathable membrane muab oxygen rau cov kab mob uas txuas rau nws, thiab zoo degrades cov pa phem nyob rau hauv dej.
Hom kev sib cais MBR tseem hu ua cov khoom sib cais hom MBR. Nws muab cov txheej txheem sib cais membrane nrog cov txheej txheem kev kho dej khib nyiab. Khoom-kua sib cais efficiency. Thiab vim hais tias cov ntsiab lus ntawm cov activated sludge nyob rau hauv lub aeration tank nce, efficiency ntawm biochemical cov tshuaj tiv thaiv yog zoo dua, thiab organic pollutants yog ntxiv degraded. Hom kev sib cais MBR feem ntau yog siv hauv MBR cov dej phwj tuaj kho.
Extractive MBR (EMBR) muab cov txheej txheem sib cais ntawm daim nyias nyias nrog anaerobic digestion. Selective membranes extract cov tshuaj lom neeg los ntawm cov dej khib nyiab. Cov kab mob anaerobic hloov cov organic teeb meem hauv cov dej khib nyiab rau hauv methane, lub zog roj, thiab hloov cov khoom noj (xws li nitrogen thiab phosphorus) rau hauv ntau hom tshuaj, yog li ua kom muaj peev xwm rov qab los ntawm cov dej khib nyiab.
