MBBR yog dab tsi? Daim ntawv qhia ua tiav rau kev txav txaj biofilm reactor thev naus laus zis

MBBR yog dab tsi?

MBBR (Moving Bed Biofilm Reactor) yog ib qho kev kho dej khib nyiab siab heev uas muab cov txiaj ntsig ntawm ob qho tib si ncua kev loj hlob (activated sludge) thiab txuas nrog kev loj hlob (biofilm). Tsim nyob rau hauv Norway thaum lig 1980s, nws tau dhau los ua ib qho ntawm cov txiaj ntsig zoo tshaj plaws thiab tau txais kev siv tshuaj lom neeg thoob ntiaj teb.

 

Ntawm nws lub hauv paus, MBBR siv ntau txhiab tus kws tsim kho tshwj xeeb, pub dawb -floating yas xov xwm nqa hauv lub tank aeration. Cov neeg nqa khoom no muab thaj chaw tiv thaiv kab mob rau cov kab mob kom txuas thiab tsim cov kab mob biofilm- cov kab mob nplua nuj ntawm cov kab mob uas noj cov pa phem.

 

Yuav ua li cas MBBR ua haujlwm: Cov txheej txheem piav qhia

Cov txheej txheem MBBR ua haujlwm los ntawm plaub theem tseem ceeb.

 

1. Biofilm Tsim
Cov kab mob ib txwm txuas mus rau qhov chaw tiv thaiv ntawm cov khoom siv yas. Nyob rau tib lub sij hawm, lawv loj hlob mus rau hauv ib tug ruaj khov, complex biofilm txheej uas muaj cov kab mob, protozoa, thiab lwm yam kab mob.

 

2. Nruam kev sib cuag & sib tov
Cov neeg nqa khoom nyob twj ywm nyob rau hauv tas li txav los ntawm aeration (nyob rau hauv aerobic tso tsheb hlau luam) los yog mechanical mixing (hauv anaerobic tso tsheb hlau luam). Qhov kev txav no ua kom txhua qhov poob ntawm cov dej khib nyiab hu rau lub active biofilm.

 

3. Cov pa phem tawg
Cov kab mob biofilm siv cov organic teeb meem, rhuav tshem:
BOD (Biochemical Oxygen Demand)
COD (Chemical Oxygen Demand)
Ammonia nitrogen (los ntawm nitrification)
Nitrate (los ntawm denitrification hauv thaj chaw anoxic)

 

4. Ntuj Sloughing
Thaum biofilm dhau los ua tuab dhau lawm, cov khoom siv biomass ntau dhau yuav ploj mus, tuav lub zej zog microbial tsis muaj kev cuam tshuam.

 

Qhov Tseem Ceeb Innovation: Qhov "Micro-Reactor" nyhuv
Txhua tus neeg nqa khoom ua raws li tus kheej micro-reactor qhov twg:
Cov txheej txheej sab nraud: cov kab mob aerobic (oxygen-ib puag ncig nplua nuj)
Cov khaubncaws sab nraud povtseg: anaerobic lossis facultative kab mob (oxygen-depleted ib puag ncig)
Qhov no tso cai rau tib lub sijhawm nitrification thiab denitrification hauv tib lub cab kuj
