Koj tuaj yeem ua li cas thiaj paub tseeb tias koj lub pob zeb MBRBR ua tau zoo?
MBBR TSHUAB
MBBR (txav lub txaj biofilm reactor) yog cov dej paug dej paug los ntawm kev ncua biofilm-coated nqa khoom (biomedia) hauv dej. Biofilm tsim, 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 ntau yam hauv kev tshawb nrhiav MBBR technology. Txhawm rau muab cov teeb meem biofilm hauv MBRBR, peb tuaj yeem pib los ntawm cov hauv qab no los pab koj hauv kev daws teeb meem cov txheej txheem.
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
Qeeb Miofilm Tsim:
Cov 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.
Biofilm detachment:
Cov qhab nia kub, kev puas tsuaj puas, 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.
Biofilm laus:
Lub sijhawm dhau los, Biofils yuav muaj hnub nyoog thiab dhau los ua tsis tau zoo, tsim nyog tu lossis hloov ntawm cov neeg nqa khoom los daws cov teeb meem no.
Txoj kev tsim biofilm
Inoculation pib-up
Inoculation ncaj qha:Ntxiv cov kev ua tau zoo lossis cov qauv microbial tshwj xeeb ncaj qha rau MBBR system kom ua nrawm rau kev tsim biofilm.
Indirect Inoculation:Qhia cov dej muaj cov microbes rau hauv MBBR system los ntawm kev ncig tebchaws, siv cov pej xeem microbial uas twb muaj lawm los txhawb cov biofilm tsim.
Kev hloov kho tau zoo
Ntxiv cov pa roj carbon ntau:Txhawb microbial kev loj hlob thiab biofilm tsim los ntawm kev ntxiv cov pa roj carbon kom tsim nyog, xws li cov piam thaj, rau cov kab ke.
Kho N \/ P piv:Ua kom zoo tshaj plaws cov tshuaj lom zem tshuav rau microbial kev loj hlob los ntawm kev kho cov nitrogen rau phosphorus piv, pab txhawb kev txhim kho biofilm.
Ib puag ncig cov haujlwm ua kom zoo
Tswj kub:Kev tswj hwm MBBR system nyob rau hauv qhov kev kub siab tshaj plaws rau microbial kev loj hlob txhawb nqa biofilm tsim thiab ruaj khov.
Ph Haum:Tswj cov qib pher theem tsim nyog, tsis yog kua qaub dhau los tsis dhau Alkaline, los pab txhawb cov microbial txuas thiab biofilm kev loj hlob.
Nce zuj zus yaj oxygen:Ua kom muaj kev yeem txaus ntawm cov pa oxygen yog qhov tseem ceeb rau kev txhawb nqa kev loj hlob ntawm aerobic microbes thiab biofilm tsim.
Cov chaw kho cov khoom muaj
Dougen Dougenen:Nce cov chaw nqa khoom ntawm lub cev nqaij daim tawv lossis tshuaj lom neeg los txhim kho cov microbial txuas thaj tsam thiab cov nplaum.
Kho qauv:Siv surfactants lossis lwm yam kev kho mob tshuaj kom txhim kho lub hydrophilicity lossis hydrophobicity ntawm cov cab kuj, txhawb nqa cov khoom ntawm cov microbes tshwj xeeb.
Tswjhwm hydraulic lub sijhawm khaws cia thiab khiav txaus
Kho lub sijhawm ua haujlwm rau Hydraulic (HRT):Ua kom lub sij hawm dej ntws los ntawm MBBR system kom paub meej microbes muaj lub sijhawm txaus rau kev txuas thiab kev loj hlob.
Kho tus nqi Flow:Tswj cov dej ntws los tiv thaiv biofilm detachment tshwm sim los ntawm kev ntws nrawm heev.
TxojkevKom zoo dua thiab tsis zoo
Cov no yog qee txoj hauv kev rau kev daws cov teeb meem biofilm hauv MBRBR. Xav txog cov kev xav tau ntawm peb cov neeg siv khoom biochemical, juntai cov kws tshaj lij tsim muaj ntau yam thiab lawv qhov zoo thiab qhov tsis zoo hauv kev kho kom muaj dej khib nyiab:
Cov no yog qee txoj hauv kev rau kev daws cov teeb meem biofilm hauv MBRBR. Xav txog cov kev xav tau ntawm peb cov neeg siv khoom biochemical, juntai cov kws tshaj lij tsim muaj ntau yam thiab lawv qhov zoo thiab qhov tsis zoo hauv kev kho kom muaj dej khib nyiab:
1.Ntuj biofilm tsim
Kev cia siab rau ib txwm tam sim no microbes nyob rau hauv lub system rau biofilm tsim. Cov qauv no tsis tas yuav sab nraud microbial inoculation tab sis kev sib koom tes thiab kev loj hlob ntawm cov kab tsuag hauv qab dej hauv lub inoculation. Txij li thaum inoculation kom muaj tsawg, cov ntaub ntawv biofilm maj mam, tab sis adhesion nruab nrab ntawm biofilm thiab cov cab kuj muaj zog.
Cov txiaj ntsig: Kev lag luam yooj yim, tsis tas yuav muaj cov microbial ntxiv.
Qhov tsis zoo: Biofilm tsim yuav qeeb qeeb, thiab kev kho mob pib yuav tsis ruaj khov.
