1. Kev soj ntsuam ntawm covtxoj cai thovMBBR hauv petrochemical cov dej khib nyiab
Nyob rau hauv cov txheej txheem kho MBBR, qee qhov sib zog ua kom lub cev muaj zog ntxiv rau cov txheej txheem aeration tank, thiab cov kab mob nyob ib puag ncig tau hloov pauv los ntawmgas-kua theemnyob rau hauv cov txheej txheem ib txwm mus rau solid-gas-kua peb-theemlos tsim ib qho kev sib xyaw ecosystem, uas yog lub hav zoov ntawm microorganisms muab cov kev mob zoo.
Cov av nkos ntev-hnub nyoog biofilms ua raws thiab loj hlob hauv cov lim mbbr tshem tawm, kom cov kab mob nitrifying muaj qhov chaw nyob zoo. Cov kab mob nitrifying loj hlob qeeb thiab xav tau ib puag ncig tsim nyog kom muaj sia nyob, uasua kom cov nyhuv nitrification.Lub biofilm plays lub luag haujlwm ua ke nrog cov sludge tshem tawm ntawm qhov chaw ntawm cov xov xwm raug tshem tawm mbbr, thiabqhov zoo ntawm degradationtuaj yeem siv tag nrho.
Cov kab mob uas raug tshem tawm thiab lawv cov kab mob sib kis loj hlob ua ke hauv lub pas dej. Lawv ua ketshem tawm cov organicthiabHloov cov ammonia nitrogen rau NO-N thiab NO:-N; Tsis tas li ntawd, cov kab mob uas loj hlob hauv mbbr reactor tuaj yeem tsim tau raws li kev txwv ntawm kev hloov pauv oxygen. Sab hauv anaerobic zone thiab facultative zone nyob rau hauv nruab nrabtxhawb kev ciaj sia thiab kev loj hlob ntawm cov kab mob facultative denitrifyingthiabexert cov nyhuv ntawm denitrification thiab denitrification.
Nyob rau tib lub sijhawm, lubsludge load yog heev txo, tsis muaj kev txhawj xeeb txog sludge expansion, lubefficiencykev kho cov dej khib nyiab petrochemicalyog txhim kho, thiab covkev ua haujlwm ruaj khov dua.
2. Covkev txhawb nqa thiab kev thovMBBR hauv petrochemical cov dej khib nyiab
Hauv xyoo 1991, txhawm rau ua kom tau raws li cov pej xeem' lub suab ntawm kev tiv thaiv ib puag ncig, Lub teb chaws Yelemees tsim nws cov qauv tso tawm dej rau cov tshuaj chlorine thiab nitrogen thiab TN, uas yog, siab dua 12qC, ammonia nitrogen concentration ntawm cov effluent tom qab kev kho mob xav tau. kom tsawg dua 4.5mg / L.
Ntau lub chaw kho dej khib nyiab German tau txais yuavLinpor-NMBBRtxheej txheem los txhim kho cov txheej txheem kev kho dej khib nyiab ib txwm muaj thiab tau txais txiaj ntsig zoo heev.
Txij thaum ntawd los, ntau lub teb chaws kuj tau tsimMuaj feem xyuam rau ammonia nitrogen emission qauv. Cov qauv no tau txhawb nqa kev siv xov xwm biofilter hauv ntau lub teb chaws, tshwj xeeb tshaj yog nyob rau hauv petrochemical teb, qhov twg ntau cov dej khib nyiab siv cov txheej txheem mbbr biofilter.
Lub Bisai City Oil Refinery hauv Nyij Pooj tau hloov pauv cov txheej txheem kev kho dej khib nyiab los ntawm thawj CAS mus rauLinpor-C/NMBBRtxheej txheem. Cov nyhuv ntawm kev kho dej khib nyiab tom qab mbbr media lim yog qhov pom tseeb heev.
3. Cov lus xaus
MBBR yog ua raws li cov txheej txheem CAS-Conventional Activated Sludge (activated sludge process), siv cov khoom siv thauj khoom tshem tawm los ua tus nqa khoom ntawm microbial kev ua kom ntseeg tau tias nws nyob hauvfluidized xeev.
Lim media mbbr muaj lub peev xwm muaj zogtshem tawm nitrogen thiab ammonia, thaj chaw tshwj xeeb ntawm cov cab cab uas raug tshem tawm yog qhov loj, thiab tus naj npawb ntawm cov kab mob ntawm nws qhov chaw thiab sab hauv yog loj, ua rau cov sludge concentration 6-10 npaug ntawm CAS. Nrog muaj zog purification muaj peev xwm, nws yog ib qho yooj yim rau rov qab siv cov dej reclaimed, uastxuag tus nqi rau kev tsim khoom lag luam. Yog li, MBBR yog qhov tsim nyog rau kev kho dej khib nyiab hauv kev lag luam petrochemical.
