Kev tsim kho thawj zaug ntawm MBBR txheej txheem:

MBBR txheej txheem rau kev kho dej khib nyiab tau tsim thiab pib tsim los ntawm xibfwb Hallvard Ǿdegaard thaum xyoo 1980s ntawm Norwegian University of Science thiab Technology.

twb muaj ntau tshaj 800 MBBR cov chaw kho dej khib nyiab hauv ntau tshaj 50 lub teb chaws hauv xyoo 2014, nrog txog ib nrab kho cov dej khib nyiab hauv tsev thiab ib nrab kho cov dej khib nyiab. Yam tsawg kawg yog ib feem ntawm qhov laj thawj rau qhov kev txaus siab hauv cov txheej txheem MBBR yog nws cov hneev taw me me hauv kev sib piv nrog rau lwm cov txheej txheem kho mob lom. Lub tank ntim xav tau rau cov txheej txheem MBBR feem ntau tsawg dua qhov xav tau rau cov txheej txheem sludge activated lossis lim lim tsim los kho cov dej khib nyiab tib yam.

Kev piav qhia dav dav ntawm MBBR txheej txheem:

MBBR txheej txheem yog ib qho txuas nrog kev loj hlob ntawm cov dej khib nyiab pov tseg. Ntawd yog, cov kab mob uas ua tiav kev kho mob txuas nrog cov khoom nruab nrab, xws li hauv cov lim lim lossis RBC systems. Los ntawm qhov sib txawv, nyob rau hauv kev ncua kev loj hlob ntawm cov dej khib nyiab pov tseg, zoo li cov txheej txheem activated sludge, cov kab mob uas ua tiav cov kev kho mob raug tshem tawm hauv cov cawv sib xyaw hauv lub tank aeration.

Nyob rau hauv cov pa txuas nrog kev loj hlob ntawm cov txheej txheem kev kho mob lom neeg, xws li trickling lim lossis RBC systems, cov kab mob txuas nrog rau qhov nruab nrab uas tau kho nyob rau hauv qhov chaw thiab cov dej khib nyiab tau kho ntws dhau los ntawm qhov nruab nrab nrog lawv txoj kev loj hlob lom. Nyob rau hauv sib piv, ib tug MBBR txheej txheem siv me me cov ntaub ntawv yas nqa khoom (tshwj xeeb nyob rau hauv kom meej ntxiv nyob rau hauv seem tom ntej no) raws li cov kab mob sib txuas. MBBR cov txheej txheem kev kho mob feem ntau tshwm sim hauv lub tank zoo ib yam li lub tshuab ua kom cov sludge aeration tank. Cov xov xwm cab kuj tau raug tshem tawm los ntawm lub tshuab cua diffused aeration rau cov txheej txheem anaerobic lossis los ntawm kev sib xyaw tshuab rau cov txheej txheem anoxic lossis anaerobic, raws li tau piav qhia hauv cov duab hauv qab no. Ib lub sieve feem ntau yog siv ntawm MBBR lub tank tawm kom cov khoom thauj khoom hauv lub tank.

Thawj qhov kev qhia meej feem ntau yog siv ua ntej ntawm MBBR tank. Qhov kev qhia meej thib ob kuj tseem siv tau, tab sis tsis muaj cov khoom siv rov ua dua tshiab uas xa rov qab mus rau hauv cov txheej txheem vim tias cov kab mob txaus ntshai tau khaws cia txuas nrog cov xov xwm.

MBBR Media Support Carrier System:

Cov txheej txheem MBBR siv cov khoom txhawb nqa yas yas zoo ib yam li cov hauv qab no. Raws li pom nyob rau hauv daim duab ntawd, tus cab kuj feem ntau yog tsim los kom muaj thaj chaw siab ntawm ib chav tsev ntim, kom muaj ntau qhov chaw ntawm cov kab mob sib txuas thiab loj hlob. Media txhawb nqa nqa zoo li cov uas pom hauv daim duab yog muaj los ntawm ntau tus neeg muag khoom. Ob lub zog ntawm tus cab kuj xav tau rau cov txheej txheem tsim kev suav suav kom piav qhia thiab sib tham hauv chav kawm no. Cov khoom no yog thaj chaw tshwj xeeb hauv m 2 / m 3 thiab qhov tsis muaj qhov sib piv. Qhov chaw tshwj xeeb ntawm MBBR cov neeg nqa khoom feem ntau yog nyob rau thaj tsam ntawm 350 txog 1200 m 2 / m 3 thiab qhov tsis muaj qhov sib piv feem ntau yog li ntawm 60% mus rau 90%. Tus nqi tsim nyog rau cov khoom thauj khoom no yuav tsum tau txais los ntawm cov chaw tsim khoom lossis cov neeg muag khoom.

MBBR Cov txheej txheem kho dej khib nyiab lwm txoj hauv kev:

MBBR dej khib nyiabCov txheej txheem kev kho mob yog hloov tau yooj yim thiab tuaj yeem siv ntau txoj hauv kev. Daim duabHauv qab no qhia cov duab kos rau rau 6 txoj hauv qab no. Nco ntsoov tias, raws li yav dhau loshais, thawj qhov kev qhia meej thiab cov lus qhia theem nrab yog qhia rau txhua tus

txheej txheem lwm txoj kev, tab sis tsis muaj sludge recycle li nyob rau hauv ib tug pa activated sludgetxheej txheem.

1. Ib theem BOD tshem tawm

2. Ob theem BOD tshem tawm

3. Ob theem BOD tshem tawm thiab Nitrification

4. Ib theem tertiary Nitrification

5. Pre-Anoxic Denitrification

6. Post-Anoxic Denitrification

Txheej txheem cej luam ntawm MBBR txheej txheem tsim xam:

Qhov tseem ceeb ntawm kev tsim qauv siv los txiav txim siab qhov xav tau MBBR tank loj yog qhov chaw thauj khoom ntawm qhov chaw (SALR) hauv g / m 2 / d. Lub g / d hauv SALR units yog hais txog g / d ntawm qhov ntsuas tau raug tshem tawm thiab m 2 hauv SALR units yog hais txog thaj tsam ntawm tus cab kuj. Yog li, rau BOD tshem tawm SALR yuav yog g BOD / hnub nkag mus rau MBBR tank ib m 2 ntawm cov chaw nqa khoom. Rau nitrification reactor, SALR yuav yog g NH 3 -N/hnub nkag mus rau MBBR tank ib m 2 ntawm cov cab kuj. Thaum kawg, rau kev tsim denitrification, SALR yuav yog g TSIS MUAJ 3 -N/hnub ib m 2 ntawm cov chaw nqa khoom.

Rau ib qho ntawm cov txheej txheem no, tus qauv tsim tus nqi rau SALR tuaj yeem siv ua ke nrog cov qauv tsim ntawm cov dej khib nyiab thiab BOD, ammonia, lossis nitrate concentration, xam qhov xav tau ntawm cov cab kuj nyob rau hauv MBBR tank. Tus tsim cov khoom ntim tuaj yeem suav nrog siv tus nqi paub rau thaj tsam tshwj xeeb ntawm tus neeg nqa khoom (m 2 / m 3). Thaum kawg, tus tsim tus nqi rau tus neeg nqa khoom sau % tuaj yeem siv los suav cov ntim tank xav tau.
