Kev tshawb fawb pom tau hais tias qhov tseeb tsim MBBR Technology nrog polyethylene media li Biofilm kev pabcuam muaj qhov tshwj xeeb siv tau los siv rau OMS tshem tawm ntawm cov dej khib nyiab. Txoj kev hloov lub txaj Biofilm kuj tseem siv tau los ua qhov zoo tshaj plaws thiab ib puag ncig tus phooj ywg lwm txoj hauv kev rau kev tshem tawm tag nrho cov khoom noj los ntawm kev kaw lub thoob dej yug ntses lossis pej xeem thoob dej yug ntses dej khib nyiab.
Tsiv txaj txaj bioreactor (MBBR) muaj lub tank dej ntawm txhua tus qauv crammed nrog cov khoom me me. Cov yam tseem ceeb no yog cov khoom tsim tshwj xeeb nrog kev tswj xyuas qhov ntom ntom, yog li lawv tuaj yeem ua kua dej siv cov khoom siv aeration. Biofilms yuav zoo li ntawm cov khoom, thiab cov no yuav mus nrog cov dej khib nyiab hauv reactor. Cov lus tsa suab hauv lub reactor yog tsim los ntawm kev siv cov khoom aeration nyob rau hauv lub diffuser tso rau tom qab ntawm lub reactor. Cov tawv nqaij biofilm ntawm cov khoom tso cai rau cov kab mob microorganisms ua rau cov khoom siv biodegradable hauv cov dej khib nyiab thiab txo qis BOD / COD cov ntsiab lus cov ntaub ntawv nyob rau hauv lub xub ntiag ntawm oxygen nyob rau hauv cov huab cua rau fluidization. Cov dej tuav tau ntws los ntawm kab sib chaws los yog sieve los ntawm lub reactor, yog li tiv thaiv MBBR biocarrier hauv reactor. Cov cuab yeej tuaj yeem tsim los ntawm ib theem lossis ob theem kev kho raws li qhov xav tau ntawm cov dej khib nyiab.
Daim txhuam cev-hom cab kuj: Daim txhuam cev-hom MBBR xov xwm cov neeg nqa khoom muaj lub zog txhua yam, thaj chaw hauv pem teb ntau dhau, thiab cov txheej txheem tawv hauv pem teb zoo nkauj kub rau biofilms khaws cia. Lawv cov khoom spongy yog qhov hloov tau yooj yim, txawm hais tias lawv muaj lub siab xav muab tso rau ntau dua li ntau hom sib txawv.
Ecologix MBBR yog ib qho kev kho mob zoo tshaj plaws ntawm cov organic raws li kev sib sau ua ke ntawm ib txwm siv cov sludge thiab biofilm media. Txoj kev MBBR ua rau kev siv cov ntab Muaj Peev Xwm Muaj Peev Xwm MicroOrganism BioChips xov xwm hauv cov aeration thiab anoxic tso tsheb hlau luam. Cov microorganisms noj cov khoom ntuj. Cov xov xwm txhawb nqa kev txhim kho hauv pem teb rau cov organic microorganisms kom txuas thiab loj hlob. Cov cheeb tsam hauv pem teb nthuav dav txo cov hneev taw ntawm cov tso tsheb hlau luam uas xav tau los daws cov dej khib nyiab. Txoj kev kho mob tuaj yeem yog cardio thiab / lossis anaerobic thiab ua haujlwm ntawm kev thauj khoom ntau dhau.

Cov lus piav qhia ntawm Moving Bed Biofilm Reactor (MBBR)
Muaj ntau ntau hom biofilm siv rau kev kho dej, xws li trickling biofilters, rotating organic contactors (RBC), granular media biofilters, floating hlaws biofilters thiab fluidized txaj biofilters (Timmons li al., 2002), lawv txhua tus muaj koob hmoov thiab qhov tsis zoo. Lub lim lim tam sim no tsis ntim tau zoo; mechanical screws tau tsis tu ncua kev txawj inrotating organic contactors; granular media biofilters xav kom lub sij hawm qis rov qab flashing thiab fluidized txaj reactors pom hydraulic instability (Rusten li al., 2006). Hauv cov ntsiab lus no, kev hloov pauv txaj biofilm reactor (MBBR) kev tshawb fawb ib zaug tau tsim nyob rau xyoo kaum cuaj yim yim thiab thaum ntxov Nineties hauv Norway (Ødgaard li al., 1999).Tam sim no MBBR tau siv thoob ntiaj teb rau kev kho mob hauv nroog thiab kev lag luam. dej khib nyiab, raws li zoo raws li kev kho dej hauv aquaculture (Rusten li al., 2006). Hauv kev lag luam aquaculture, MBBR feem ntau siv rau nitrification, raws li kev tshem tawm ntawm tej yam ntuj tso. Txhawm rau kom nyob deb ntawm cov kab mob heterotrophic microorganisms uas noj cov khoom suav ntuj uas txwv tsis pub cov kab mob nitrifying microorganism ntawm cov khoom siv ntau dhau, MBBR feem ntau ua haujlwm ntawm cov khoom siv qis hauv cov dej hauv dej hiav txwv (Rusten li al., 2006).Piv nrog cov biofilm reactors feem ntau sib txawv. , MBBR ua rau kev siv tag nrho lub tank rau kev loj hlob ntawm biomass, nws kuj tseem muaj qhov tsis tseem ceeb ntawm lub taub hau poob thiab tsis xav kom rov qab ua ntu zus thiab tam sim no tsis xav kom txhaws (Rusten li al., 2006). Tsis tas li ntawd, qhov filling feem ntawm biofilm nqa hauv lub reactor tuaj yeem txhawj xeeb txog kev nyiam. Txawm li cas los xij, nws tau pom zoo tias kev sau cov feem yuav tsum tsawg dua 70 feem pua los tuav tus neeg muab kev pabcuam raug tshem tawm hauv lub reactor (Ding, 2012).
MBBR Kev Kho Dej Ncua Ua Haujlwm li cas?
MBBR yog ib qho kev siv thev naus laus zis raws li kev tshawb fawb biofilm, nrog rau kev ua haujlwm biofilm loj hlob tshwj xeebtsim cov khoom siv yas (lossis biomedia) uas raug tshem tawm hauv lub reactor. Nws tuaj yeem ua tau ob qho tib sinyob rau hauv aerobic thiab anaerobic tej yam kev mob, raws li qhia nyob rau hauv daim duab 2.2.1. Nyob rau hauv cov ntaub ntawv aerobic, biomediaraug tshem tawm los ntawm agitation los ntawm aeration diffusers, thaum nyob rau hauv cov ntaub ntawv anaerobic, ib tug tov khoom yogsiv los khaws cov biomedia txav (Ødgaard li al., 1999). Bio-medias yog tsim los ntawm kev sib txawvcov ntaub ntawv thiab high-density polyethylene feem ntau yog siv, uas muaj ib tug ceev txog0.95g/cm 3. Txhawm rau muab qhov siab tshaj plaws ntawm thaj chaw tshwj xeeb (m 2 / m 3), bio-medias yogtsim nyob rau hauv ntau yam duab thiab ntau thiab tsawg (Ding, 2012). Daim duab 2.2.2 qhia tau hais tias ib txwm sivbiomedia K1 nrog thaj tsam tshwj xeeb 350 m 2 / m 3 .Cov txheej txheem nitrification hauv MBBR cuam tshuam los ntawm ntau yam ib puag ncig, xws likub, pH, alkalinity, COD qib, yaj oxygen (DO) theem nyob rau hauv lub reactor,tag nrho ammonium nitrogen (TAN) theem, thiab cov xwm txheej ntawm biofilm (Rusten li al., 2006). Rauntsuas qhov ua tau zoo ntawm TAN tshem tawm hauv reactor, muaj peb yam tsis siv ntau(Pfeiffer thiab Wills, 2011): 1) ntim TAN tshem tawm tus nqi (g TAN m -3 d -1 ), 2) TAN tshem tawmtus nqi (g TAN m -2 d -1 ), 3) thiab feem pua TAN tshem tawm efficiency
