Tsiv lub txaj Biofilm Reactor Kev Kho Mob

Tsiv lub txaj Biofilm reactor

Lub txaj txav biofilm reactor (MBBR) Technology yog qhov ua tau zoo txheej txheem kev kho kom zoo. Cov kev ua tau zoo ntawm MBRB Biofilm tshuab yog cuam tshuam los ntawm ntau yam, nrog rau kev ua haujlwm muaj txiaj ntsig, thiab kev teeb tsa system, xws li pub mis thiab sib tov. Hauv kev ua haujlwm ruaj khov, kev pom ntawm cov muaj sia feem ntau yuav nyob twj ywm. Nws nyob ntawm kev pub khoom noj thiab cov biofilm loj ntawm cov cab kuj, nrog qhov nruab nrab ntawm tsawg dua 20 g \/ m². Txawm li cas los xij, hauv cov kab ke nrog scaling, cov cab kuj muaj huab hwm coj tau ntau dua. Piv txwv li, thaum cov kab mob nquag yog nyob rau ntawm sab nraud ntawm cov nplai loj. Rau cov txheej txheem zoo li nitrification lossis ammonia oxidation, qhov loj ib cheeb tsam tuaj yeem qis dua vim muaj kev loj hlob qeeb ntawm cov kab mob.

Cov organic chaw thau khoom

Cov organic chaw thau khoom cov nqi hauv MBRB tau raws li thaj chaw muaj kev tiv thaiv thiab tau mus txog 100 gcod \/ m² \/ d, keeb kwm biofm thiab keeb kwm chaw thau khoom. Nyob rau hauv xws li lub siab - chaw thau khoom, khoom noj cov pa tawm yuav dhau los ua kev txwv tsis pub muaj kev txo qis. Piv rau cov sludge tshuab, MBRB tau tswj hwm cov slude ntau dua ib qho kev sib faib. Nrog rau qhov nruab nrab biofilm ntawm 20 g \/ m² ntawm cov chaw nplooj nkoj thiab 70% sau tau, cov ntsiab lus sludge ntawm thaj chaw ntawm 500 m³ yog kwv yees li 7 g \/ l. Qhov no yog ua tiav tsis muaj qhov xav tau rau sludge reflux, yog li sim ua haujlwm thiab tshem tawm cov cai rau sludge reflux khoom siv.

Tus txheej txheem MBBr tau tseem tau tsim kho qhov kev tshem tawm ntawm ammonia los ntawm cov txiaj ntsig nitrentification thiab cov txheej txheem denitrification. Hauv cov txheej txheem tsis raug kho, ammonium ions yog tag oxidized los ntawm nitrate yog txo rau nitrogen roj los ntawm kev ua ntej \/ post - Denitrication. Qhov kev txwv no feem ntau nqa tawm hauv ob reactors. Inorganic carbon feem ntau yog muab ua alkalinity los txhawb cov oxidation ntawm ammonium. Denitrification yuav tsum tau npaj ua degradable organic teeb meem, xws li Methanol, ua hluav taws xob lees txais. Ib nrab nitricification, uas suav nrog nitrosation thiab anaerobic ammonium oxidation, kuj tseem ua tau los ntawm kev tswj cov pa oxygen nkag mus rau biofilm. Qhov no tso cai rau kev tshem tawm cov nitrogen los ntawm cov dej khib nyiab los ntawm ib reactor, uas yog oxidation ntawm nitrite rau nitrite yog inhibited.
