Cov xwm txheej cuam tshuam rau kev hloov pauv oxygen ntawm MBBR ntxhib npuas diffusers

1. Diffuser yam ntxwv
npuas loj:
Cov npuas me me muaj thaj tsam loj dua, uas tuaj yeem ua rau thaj tsam ntawm cov pa-kua sib cuag, yog li txhim kho cov pa oxygen hloov pauv. Hauv qhov sib piv, cov npuas loj muaj qhov me me ntawm thaj chaw tshwj xeeb thiab qhov ua tau zoo ntawm cov pa oxygen tsawg.
Piv txwv li, kev siv cov microporous diffusers tuaj yeem tsim cov npuas me me, uas txhim kho cov pa oxygen hloov pauv tau zoo, tab sis tej zaum yuav ua rau txhaws. Coarse npuas diffusers tsim cov npuas loj, nrog rau cov pa oxygen hloov mus rau qhov tsis tshua muaj txiaj ntsig, tab sis tsis ua rau txhaws.
Bubble distribution:
Kev faib ua npuas sib txawv tuaj yeem ua kom ntseeg tau tias txhua qhov chaw hauv lub reactor tuaj yeem tau txais cov pa oxygen txaus thiab txhim kho tag nrho cov pa oxygen hloov pauv tau zoo. Yog tias cov npuas faib tsis sib npaug, nws yuav ua rau cov pa oxygen tsis txaus hauv cov cheeb tsam hauv zos, cuam tshuam rau kev kho mob.
Piv txwv li, siv cov diffusers tshwj xeeb uas tsim los, xws li cov phaj ntxeem tau, cov diffusers annular, thiab lwm yam, tuaj yeem ua tiav cov npuas npuas ntau dua.
Cov khoom siv diffuser:
Cov khoom siv ntawm diffuser cuam tshuam rau nws cov khoom nto thiab oxygen hloov kev ua haujlwm. Qee cov ntaub ntawv muaj qhov zoo dua hydrophilicity thiab roj permeability, uas tuaj yeem txhawb kev hloov pauv ntawm oxygen.
Piv txwv li, diffusers ua los ntawm cov ntaub ntawv xws li silicone thiab ceramics yuav muaj cov pa oxygen ntau dua.

2. Cov yam ntxwv ntawm cov dej khib nyiab
Kub:
Cov dej khib nyiab kub muaj qhov cuam tshuam loj rau kev solubility thiab diffusion coefficient ntawm oxygen. Feem ntau hais lus, qhov nce hauv qhov kub thiab txias yuav txo qhov solubility ntawm oxygen, tab sis ua kom cov diffusion coefficient ntawm oxygen.
Nyob rau hauv ib qho chaw, qhov kub siab dua tuaj yeem ua rau kom muaj txiaj ntsig ntawm kev hloov pauv oxygen, tab sis qhov kub thiab txias yuav ua rau muaj kev cuam tshuam tsis zoo rau cov kab mob.
tus nqi pH:
Tus nqi pH cuam tshuam rau lub neej ntawm cov pa oxygen hauv cov dej khib nyiab thiab kev ua haujlwm ntawm cov kab mob. Cov kab mob sib txawv muaj cov kev xav tau oxygen sib txawv thiab muaj peev xwm metabolic ntawm pH sib txawv.
Piv txwv li, qee cov kab mob feem ntau yuav nqus cov pa oxygen nyob rau hauv acidic tej yam kev mob, thaum cov pa oxygen hloov efficiency yuav raug txo nyob rau hauv alkaline tej yam kev mob.
Concentration ntawm pollutants:
Qhov concentration ntawm cov pa phem hauv cov dej khib nyiab cuam tshuam rau kev tiv thaiv kev hloov pauv oxygen. Cov ntsiab lus siab ntawm cov organic teeb meem, tshem tawm cov khib nyiab thiab lwm yam kuab paug tuaj yeem tsim cov txheej txheem fouling ntawm qhov chaw diffuser, cuam tshuam kev hloov pauv ntawm oxygen.
Tsis tas li ntawd, qee cov pa phem tuaj yeem hnov ​​​​mob nrog oxygen, haus cov pa oxygen, thiab txo qis kev ua haujlwm ntawm cov pa oxygen.

3. Cov xwm txheej ua haujlwm
Aeration siv zog:
Aeration intensity yog hais txog cov huab cua nkag mus rau hauv lub reactor ib lub sij hawm. Ua kom cov aeration siv tau tuaj yeem ua rau nce tus nqi tsim thiab cov npuas, ua kom cov pa roj-kua sib cuag cheeb tsam, thiab yog li txhim kho kev ua haujlwm ntawm cov pa oxygen.
Txawm li cas los xij, kev siv zog ntau dhau tuaj yeem ua rau muaj teeb meem xws li kev sib xyaw ua npuas dej thiab cov dej ntws ntxiv shear quab yuam, uas yuav txo tau cov pa oxygen hloov pauv. Nyob rau tib lub sijhawm, kev siv aeration ntau dhau kuj tseem yuav ua rau kev siv hluav taws xob ntau ntxiv thiab cov nqi khiav lag luam.
Hydraulic tuav lub sijhawm:
Hydraulic retention time yog hais txog lub sijhawm nyob ntawm cov dej khib nyiab hauv lub reactor. Lub sijhawm hydraulic tuav ntev dua tuaj yeem muab cov pa oxygen ntau lub sijhawm hloov mus rau hauv dej thiab txhim kho cov pa oxygen hloov pauv.
Txawm li cas los xij, lub sij hawm tuav hydraulic ntev dhau lawm yuav txo qis kev kho lub peev xwm ntawm lub reactor, ua kom cov av hauv pem teb thiab cov nqi tsim kho. Yog li ntawd, nws yog ib qho tsim nyog los xaiv lub sijhawm hydraulic kom haum raws li qhov xwm txheej tiag tiag.
Dej ntws hauv lub reactor:
Lub xeev cov dej ntws hauv lub reactor yuav cuam tshuam rau kev txav mus los ntawm cov npuas thiab lub sijhawm sib cuag roj-kua. Kev sib xyaw dej zoo tuaj yeem ua rau cov npuas sib npaug sib npaug hauv lub reactor, ua kom cov pa roj-kua sib cuag, thiab txhim kho cov pa oxygen hloov pauv.
Piv txwv li, kev siv cov khoom siv xws li agitators thiab reflux twj tso kua mis tuaj yeem txhim kho cov dej ntws hauv lub reactor thiab txhim kho cov pa oxygen hloov pauv.

4. Cov yam ntxwv ntawm Biofilm
Biofilm thickness:
Lub thickness ntawm biofilm yuav cuam tshuam rau diffusion tsis kam ntawm oxygen hauv biofilm. Thicker biofilms yuav ua rau kom cov pa hloov pauv tsis kam thiab txo cov pa oxygen hloov mus ua haujlwm.
Yog li ntawd, lub thickness ntawm biofilm yuav tsum tau tswj kom tsis txhob muaj kev loj hlob ntau dhau. Lub thickness ntawm biofilm tuaj yeem tswj tau los ntawm kev kho cov kev ua haujlwm tsis tu ncua thiab ntxuav cov muab tub lim tsis tu ncua.
Biofilm ua haujlwm:
Kev ua haujlwm ntawm biofilm cuam tshuam rau nws qhov kev thov rau oxygen thiab nws qhov kev siv tau zoo. Biofilms nrog kev ua haujlwm siab dua tuaj yeem nqus thiab siv cov pa oxygen zoo dua, txhim kho kev ua haujlwm ntawm oxygen hloov mus.
Kev ua haujlwm ntawm biofilm tuaj yeem txhim kho los ntawm kev ua kom zoo rau kev ua haujlwm thiab ntxiv cov as-ham.
