Kev tsis
MBBR (txav lub txaj biofilm reactor) yog cov dej paug dej paug los ntawm kev ncua biofilm-coated nqa khoom (biomedia) hauv dej. Biofilformation, lossis biofating, yog ib qho ntawm cov txheej txheem tseem ceeb ntawm MBBR cov thev naus laus zis, tseem ceeb rau cov kab ke ua haujlwm tau zoo thiab ruaj khov. Juntai muaj kev paub txog kev tshawb xyuas MBBR Technology. Rau chaw teeb meem teeb meem hauv MBRBR, peb tuaj yeem pib los ntawm cov hauv qab no los pab koj hauv kev daws teeb meem cov teeb meem kev txhim kho.
Ntsiab Cai ntawm Biofilm Tsim
Cov txheej txheem Biofilm tsim tshwj xeeb xws li thawj microbial kos duab, kev loj hlob, thiab theem ua tiav. Thaum lub sijhawm tus txheej txheem no, microbes ua raws li cov biomedia hauv Mbbr Reactor, sib sau ua cov biofilm ruaj khov. Yam khoom xws li kub, pH, yaj cov pa, piv txwv ntawm cov cab kuj tuaj yeem cuam tshuam qhov ceev thiab zoo ntawm biofilm tsim.
Yam cuam tshuam rau kev tsim biofilm tsim
• Kev tsim kho biofilly qeeb (qeebCov xwm txheej zoo li kub tsawg, cov txiaj ntsig tsis txaus, thiab cov p p tsis zoo yuav ua rau muaj kev txhim kho qeeb biofilm.
• Npog Biofilm: Cov nqi hluav taws kub uas muaj kev puas tsuaj, kev puas tsuaj rau kev puas tsuaj, lossis anoxia sab hauv los ntawm cov biofilils tuab zuj zus tuaj yeem ua rau biofilm detachment.
Tsis ncaj biofilm thickness: uneven dej faib lossis cab kuj sib sau ua ke tuaj yeem ua rau tsis ncaj biofilm thickness, cuam tshuam rau kev kho mob.
• Kev laus biofilm: Sijhawm rau lub sijhawm, Biofilms yuav muaj hnub nyoog thiab dhau los ua qhov tau txais txiaj ntsig zoo, tsim nyog tu lossis hloov cov neeg nqa khoom los daws cov teeb meem no.
Txoj kev tsim biofilm
- Inoculation pib-up
Tus Saib Xyuas Ncaj Ncees: Ntxiv cov kev ua kom muaj kev cia siab lossis cov qauv microbial tshwj xeeb
ncaj qha rau MBRBR system kom ua kom muaj tseeb biofilm tsim.
Indirect Inoculation: Qhia cov dej muaj cov microbes rau hauv
Lub MBBR system los ntawm kev ncig ncig, siv cov microbial uas twb muaj lawm
Zej zog los txhawb kev tsim biofilm.
- Kev hloov kho tau zoo
Ntxiv cov pa roj carbon: Txhawb kev loj hlob microbial thiab biofilm
tsim los ntawm kev ntxiv ib qho kev tsim nyog ntawm cov pa roj carbon kom tsim nyog, xws li
piam thaj, rau lub kaw lus.
Kho N \/ P Piv Txwv: Txhim kho cov khoom noj muaj txiaj ntsig zoo rau
microbial kev loj hlob los ntawm kev kho cov nitrogen rau phosphorus piv,
Saib xyuas kev txhim kho biofilm.
- Ib puag ncig cov haujlwm ua kom tau zoo:
Tswj Qhov Kub: Tswj MBRBR system nyob rau hauv
Qhov kub ntawm qhov ntsuas kub rau microbial kev loj hlob txhawb nqa biofilm
tsim thiab ruaj khov.
PHOONATION: Tswj xyuas qib pher tsim nyog, tsis yog kua qaub dhau
tsis dhau Alkaline, los pab txhawb microbial connctment thiab biofilm
kev loj hlob.
Nce zuj zus yaj oxygen: Ensuring ib qho txaus
yaj oxygen yog qhov tseem ceeb rau kev txhawb nqa kev loj hlob ntawm aerobic
microbes thiab biofilm tsim.
- Cov chaw kho cov khoom muaj
NTSA: Nce cov cab kuj sib nrug
los ntawm kev siv lub cev lossis tshuaj lom neeg los txhim kho microbial
Ntxawg thaj chaw thiab cov nplaum.
Kev hloov kho deg deg deg: Siv Surfactants lossis Lwm Yam Tshuaj
kev kho mob txhawm rau txhim kho lub hydrophilicity lossis hydrophobicity ntawm lub
cov cab kuj nto, txhawb nqa cov ntawv txuas ntawm cov hom
microbes.
- Tswjhwm hydraulic lub sijhawm khaws cia thiab khiav txaus
Kho cov kev tuav haujlwm hydraulic (HRT): Optimizing lub sijhawm
dej ntws los ntawm MBRBR system los xyuas kom microbes muaj
txaus lub sij hawm rau txuas thiab kev loj hlob.
Kho tus nqi Flow: Tswj cov dej ntws los tiv thaiv biofilm
kev nkhaus los ntawm kev ntws nrawm.
