MBBR Media loj, zoo li voids thiab puab porosity
Cov voids loj yuav ua rau detachment ntawm biofilms vim siab shear rog thiab yog li yuav ua rau kom lub sij hawm tsim biofilm thaum lub sij hawm thawj colonization. Thaum lub sij hawm muaj kev cuam tshuam kev poob siab, ib feem loj ntawm biofilm raug rau cov tshuaj lom uas yuav ua rau kev ua haujlwm tsis zoo.
Cov voids me me thiab sib sib zog nqus tso cai rau tsim sai ntawm biofilms nyob rau hauv qhov tob qhov pores vim qis sloughing tawm thaum pib txheej txheem. Fine pore qauv nrog cov voids ntxaum tseem tiv thaiv cov kab mob tiv thaiv kev poob siab. Yog li MBBR media nrog cov qauv pore zoo muaj kev tiv thaiv zoo dua tiv thaiv kev poob siab thiab pib sai dua piv rau lub caij uas muaj cov voids loj thiab qhib.
Finer voids kuj tso cai rau kev loj hlob ntawm thinner biofilms uas khaws ib feem loj ntawm biomass tam sim no nyob rau hauv biofilm raug rau cov kua ntau ntawm lub reactor rau substrate uptake. Qhov no muaj qhov zoo dua diffusion gradients tso cai rau kev tshem tawm zoo dua.
Cov kab noj hniav sib sib zog nqus tso cai rau kev loj hlob ntawm cov kab mob tshwj xeeb xws li cov kab mob Anammox thiab Denitrifying cov kab mob hauv cov pores sab hauv ua kom cov txheej txheem ua haujlwm tau zoo thiab kev ntseeg siab nyob rau lub sijhawm ua haujlwm. Txawm li cas los xij, cov qauv pore zoo heev tuaj yeem cuam tshuam cov khoom nqa khoom nrog ntau dhau ntawm biofilm tsim nyob rau hauv lub pore puab thiab ua rau nws hnyav dua. Ntxiv rau qhov tsis zoo ntawm kev nkag mus rau hauv lub qhov pore rau substrate, cov biofilms sab hauv ua tsis tshua muaj zog thiab rov ua dua lub sijhawm ua haujlwm.
Yog li, MBBR cov ntaub ntawv xov xwm uas muaj cov qauv pore txaus thiab cov porosity sab hauv yog qhov xav tau ntau vim nws muaj ntau yam txiaj ntsig xws li:
-
Faster thiab zoo colonization
-
Kev tiv thaiv cov kab mob tiv thaiv kev poob siab nyob rau tib lub sijhawm muab kev nkag mus tau zoo rau hauv biofilms sab hauv kom zoo dua substrate diffusion.
-
Tsim nyog detachment, shearing thiab yaig ntawm biofilms nyob rau hauv tas li ntawd mus tiv thaiv kev loj hlob thiab clogging.
-
Thinner biofilm kev loj hlob nrog zoo dua diffusion gradients cia zoo dua substrate uptake thiab tshem tawm tau zoo.
Ntawm qhov tsis sib xws tam sim no cov khoom siv yas raws li MBBR xov xwm keeb kwm muaj cov voids loj dua uas muaj ntau yam tsis zoo xws li:
-
Tsis zoo pib colonization vim shearing ntawm biomass thaum pib.
-
Kev tiv thaiv tsawg kawg nkaus tiv thaiv kev poob siab ua ntej cov khoom siv biofilms tuab yog tsim nrog EPS los tiv thaiv lawv.
Tsis zoo diffusion gradient nrog tsawg nkag mus rau sab hauv biofilms nyob rau hauv tuab biofilm tsim.
