Moving Bed Biofilm Reactor (MBBR) yog txoj kev kho dej khib nyiab tshiab uas txhua lub tuam txhab xav tau kev lim dej pov tseg yuav tsum xav txog. Kev lag luam thoob plaws ntau qhov chaw yuav tsum kho cov dej khib nyiab uas lawv tsim los rov siv dua lossis tso tawm rau hauv cov dej ntuj. Qhov kev sib tw rau cov kev lag luam no nyob hauv kev nrhiav cov txheej txheem kho dej khib nyiab uas muaj txiaj ntsig zoo thiab muaj txiaj ntsig.
Cov txheej txheem MBBR txuag chaw, yooj yim rau kev khiav lag luam, muaj cov nqi kho mob tsawg, tuaj yeem tiv taus kev poob siab, thiab kho cov dej khib nyiab zoo. Tsis tas li ntawd, nws yog cov txheej txheem lom neeg uas tuaj yeem ua haujlwm nyob rau hauv ob qho tib si anaerobic thiab aerobic ib puag ncig, nrog rau kev kho mob siab thiab kev cuam tshuam ib puag ncig tsawg. Kab lus no yuav muab cov lus qhia ntxaws ntxiv rau MBBR, piav qhia nws qhov zoo thiab qee qhov tsis zoo los xav txog.
MBBR Wastewater Treatment yog dab tsi?
Lub Moving Bed Biofilm Reactor yog txheej txheem kev kho dej khib nyiab lom neeg, txhais tau tias nws yog txheej txheem ntuj tsim uas siv biofilm tshem tawm cov khib nyiab ntawm cov dej khib nyiab. Cov kab mob uas txuas nrog cov xov xwm siv cov khoom pov tseg uas tsis xav tau, tawm hauv cov dej huv.
Cov thev naus laus zis no tau tshaj tawm thawj zaug thaum xyoo 1980s los ntawm xibfwb Hallvard degaard ntawm Norwegian University of Science thiab Technology. Txij thaum ntawd los, nws tau dhau los ua ib txoj hauv kev nrov ntawm kev kho dej khib nyiab vim nws cov txiaj ntsig tseem ceeb. Cov txheej txheem muab txoj hauv kev nyab xeeb thiab ib puag ncig zoo los tshem tawm cov khoom siv organic, ntsuas raws li kev xav tau ntawm biochemical oxygen (BOD), nrog rau kev ua tiav nitrification thiab denitrification.
Qhov zoo ntawm MBBR Biological Kev Kho Cov Dej Num
Muaj ntau qhov zoo ntawm MBBR kev kho dej khib nyiab. Cov txiaj ntsig no ua rau cov txheej txheem biofilm reactor yog qhov kev xaiv zoo tshaj plaws rau qee qhov chaw tshaj li cov txheej txheem ib txwm muaj xws li membrane bioreactor lossis activated sludge.
Perfect Wastewater Solution for Space Constraints
Ib qho txiaj ntsig tseem ceeb ntawm MBBR yog nws lub cev me me hneev taw. Qhov tseeb, MBBR paub txog nws qhov loj me piv rau lwm txoj kev kho dej lom. Tib lub ntim ntawm cov dej khib nyiab tuaj yeem kho tau los ntawm MBBR lub tank uas tsuas yog ib feem ntawm qhov chaw xav tau los ntawm lub tank siv rau lub lim dej lossis cov txheej txheem sludge.
Yog tias qhov chaw xav tau los ua kom nws cov dej khib nyiab tuaj yeem ua kom muaj peev xwm kho tau, MBBR tso tsheb hlau luam yog qhov kev xaiv zoo tshaj plaws los txiav txim siab, vim tias lawv tuaj yeem yooj yim ntxiv rau cov kab ke uas twb muaj lawm yam tsis muaj qhov chaw tseem ceeb. Cov tso tsheb hlau luam uas twb muaj lawm kuj tuaj yeem rov kho dua los siv ua MBBR aeration tanks.
Yooj yim rau siv rau cov neeg ua haujlwm tsis muaj kev paub txog tsob nroj
Lwm qhov zoo ntawm biofilm reactors yog lawv txoj haujlwm yooj yim. Txawm hais tias kev tshawb fawb tom qab cov txheej txheem no yuav nyuaj me ntsis, cov txheej txheem nws tus kheej yog ncaj qha.
Cov tuam txhab uas tsim cov dej khib nyiab yuav tsum tau txiav txim siab ntau yam los xam cov qauv tsim tau zoo tshaj plaws rau lawv cov kab ke MBBR. Thaum qhov tsim nyog tau txiav txim siab, kev khiav hauj lwm qhov system yog qhov yooj yim. Vim tias lub kaw lus hloov tau yooj yim thiab tuaj yeem teb cov kev hloov pauv tau yooj yim, tus neeg teb xov tooj tsis tshua xav tau kev hloov kho.
Lwm qhov zoo ntawm MBBR yog tias nws yuav tsum tau kho me ntsis.
Tsis zoo li lwm cov kab ke uas feem ntau xav tau kev saib xyuas ua kom lub cev ua haujlwm, MBBR systems nyiam ua haujlwm zoo thiab ua haujlwm zoo ntawm lawv tus kheej nrog kev cuam tshuam tsawg.
Resistant rau Shock Loads
MBBR cov tshuab muab kev hloov pauv tau yooj yim thiab tuaj yeem hloov kho rau qhov sib txawv ntawm cov khoom siv tau zoo. Qhov no txhais tau tias lawv tuaj yeem tiv thaiv kev poob siab zoo. Vim hais tias MBBR cov tshuab kos rau cov txiaj ntsig ntawm ob qho tib si ruaj khov thiab ncua kev loj hlob ntawm cov txheej txheem lom neeg, lawv tuaj yeem tswj cov khoom siv organic siab yam tsis muaj kev cuam tshuam los ntawm kev poob siab lossis lwm yam kev hloov pauv loj.
Ua haujlwm nrawm nrog Lub Sijhawm Hydraulic Tsawg
Hydraulic retention time (HRT) yog qhov ntsuas ntawm lub sijhawm siv dej ntau npaum li cas los kho cov neeg muaj zog. Rau qee lub tshuab, qhov no tuaj yeem siv sijhawm ntev, ua rau cov nqi ua haujlwm qeeb. Thaum nws los txog rau MBBR systems, lawv cov qauv tsim ua rau lawv ua haujlwm sai, ua tiav HRT qis. Feem ntau, HRT rau MBBR systems tsuas yog ob peb teev lossis tsawg dua.
Qhov tsis zoo ntawm MBBR Kev Kho Dej Ncua Dej
Raws li nrog txhua qhov kev daws teeb meem, MBBR kuj muaj qee qhov tsis zoo. Qhov tsis zoo ntawm MBBR system suav nrog:
Accumulation ntawm Carriers:
Hauv kev xyaum, nws yog ib qho uas cov neeg nqa khoom tuaj yeem khaws cia hauv thaj chaw hauv cheeb tsam vim muaj kev txhawb nqa ntawm aeration thiab dej ntws. Txhawm rau txo qhov teeb meem no, kev txhim kho hauv cov txheej txheem ntawm cov kav dej aeration thiab cov qauv ntawm lub reactor yog tsim nyog. Lub reactor tus qauv feem ntau txiav txim siab nws cov yam ntxwv hydraulic. Hauv kev tsim qauv engineering, kev ua kom zoo ntawm kev tsim kho thiab cov yam ntxwv hydraulic ntawm lub reactor los ntawm kev sim dav tuaj yeem txo qis kev siv hluav taws xob thiab ntxiv txhim kho cov txiaj ntsig kev lag luam ntawm MBBR.
Clogging:
Thaum lub qhov hluav taws xob ntawm MBBR reactors feem ntau nruab nrog grate los yog daim phiaj los tiv thaiv cov cab kuj poob, lawv muaj feem cuam tshuam. Hauv kev tsim kho vaj tse, cov khoom siv hluav taws xob tuaj yeem ntsia tau rau kev tu lub sijhawm, lossis cov cuab yeej siv cua rov qab tuaj yeem tsim los tiv thaiv kev txhaws.
Kev lag luam uas yuav tau txais txiaj ntsig los ntawm MBBR Kev Kho Dej Pov Tseg
Txhua qhov kev lag luam uas yuav tsum tau kho lossis rov ua dua cov dej khib nyiab uas nws tsim tau tuaj yeem tau txais txiaj ntsig los ntawm MBBR system. Ntau qhov kev lag luam uas tuaj yeem siv tau zoo MBBR los kho lawv cov dej khib nyiab suav nrog kev lag luam textile, kev tsim tshuaj lom neeg, kev lag luam zaub mov thiab dej haus, thiab cov dej phwj hauv nroog.
Nrhiav qhov zoo tshaj plaws MBBR system rau koj daim ntawv thov
MBBR tsim tau zoo tuaj yeem txuag tau lub tuam txhab chaw, nyiaj txiag, thiab sijhawm thaum muab cov peev txheej kho dej zoo heev.
