AAO + MBR Vs. AOO txheej txheem
Tsis zoo li cov txheej txheem AAO - MBR cov txheej txheem feem ntau siv cov phiaj xwm ua kom tsis txhob muaj fiber thiab cov plaub hau entanglement hauv membrane fibers. Lub pore loj yog ib txwm 1mm.
Tsis zoo li cov tsoos AAO cov txheej txheem, AAO + MBR cov txheej txheem feem ntau ua haujlwm ntau dua los ntawm slude recirculation los ntawm kev cuam tshuam phosphorus tso tawm hauv thaj chaw anaerobic. This involves recirculating the sludge from the membrane zone to the beginning of the aerobic zone, from the aerobic zone effluent to the beginning of the anoxic zone, and from the anoxic zone effluent to the beginning of the anaerobic zone.
Piv rau cov tsoos AAO cov txheej txheem hauv AAO + MBr yog feem ntau siab dua, ncav 8000-1-1-1-1 txog 8,000 ntxiv rau hauv MBR TANK. Qhov no siab dua sludge concentration txhais tau tias nws tuaj yeem tiv cov dej zoo thiab ntim ntau dua thiab tuaj yeem tsim cov dej loj dua rau ib lub sijhawm.
Piv rau cov tsoos AAO txheej txheem, qhov tseeb ntws tsawg dua hauv txhua cheeb tsam ntawm AAO + MBR cov txheej txheem yog qhov siab dua. Qhov kev ua tau ntws tau tsuas yog txo qis cov kev ua haujlwm zoo ntawm kev rov qab los, thiab kev hloov pauv ntawm txhua cheeb tsam, thiab kev hloov pauv ntawm cov kev coj ua rau lub taub hau poob thiab weir.
Qhov zoo ntawm AAO + MBR
Nyob rau hauv qee qhov kev ua haujlwm, MBR zoo thiab ua tiav tau txuas ntxiv sludge - dej sib cais, rov qab cov MLSS mus rau Bioreactor. Qhov no zam qhov teeb meem ntawm residual sludge tau muaj nyob rau hauv ib qho kev ua kom lub taub roj av theem nrab thiab tom qab ntawd ua tiav rau hauv cov tsoos AOA txheej txheem. Nws daws cov teeb meem zoo xws li qhov xav tau loj sho taub dej tas, thiab muaj peev xwm sludge kev ua tau zoo los ntawm kev hloov ib puag ncig los ntawm ib puag ncig hloov pauv thiab sludge idleness.
Nws ua tiav sludge - dej sib cais cuam tshuam los ntawm cov txheej txheem theem nrab ntawm lub tiab hauv lub AAOO. Vim yog cov yam ntxwv microporous ntawm daim nyias nyias khoom, tab sis kuj tau khaws cov roj ntsha molbine, tab sis kuj tseem ua kom zoo ua haujlwm zoo thiab kho tau zoo ruaj khov. Cov tshuaj tua tsiaj ntau ntxiv hauv Biomeactor tseem ceeb txhim kho cov khoom siv uas poob siab ntawm cov ensor lub sijhawm thiab ib koog reactor ntim. Hauv MBR cov txheej txheem, ua tiav sib cais ntawm HRT thiab SRT tso cai rau daim nyias nyias thiab ua tiav MLSS ntau npaum li 10,000-20,000 mg / l.
AAO + MBR siv cov tshuaj nitrogen thiab phosphorus tshem tawm muaj peev xwm ntawm lub itoo txheej txheem, txhim kho cov txiaj ntsig ntawm mbthoral ntawm MBR. Ua ke nrog kev tuav khaws nyiaj tau zoo ntawm daim nyias nyias, cov txiaj ntsig no ua rau muaj effluent SS thiab turrididity nce xoom.
AAO + MBR cov txheej txheem nta cov qauv ua haujlwm thiab cov khoom siv hauv nruab nrab, txo cov nqi av thiab sijhawm.
