Tus txheej txheem MBBR tshiab yog cov txheej txheem kev kho dej huv uas tau ua tiav raws li cov kev ua yeeb yam anoxic-aerobic. Cov txheej txheem no tsis tsuas yog khaws cov ntsiab lus zoo ntawm cov txheej txheem qub, tab sis kuj ntxiv rau cov teebmeem qub anoxic los txhim kho qhov cuam tshuam ntawm endogenous den endogenous tshem tawm.
Qhov kev txhim kho no ua rau cov txheej txheem MBR tshiab kom tau txais cov pa paug tshiab xws li cov organic, nitrogen, thiab phosphorus thaum muaj kev kho kom muaj pov tseg. Nyob rau tib lub sijhawm, cov txheej txheem kuj tseem qhia MBBR thev naus laus zis, uas yog thev naus laus zis uas siv cov biofilms txuas rau kev txav chaw kom zoo. Los ntawm cov thev naus laus zis xws li cov organic, nitrogen, thiab phosphorus nyob rau hauv dej lwg tuaj yeem ua rau muaj kev ntxhov siab thiab raug tshem tawm cov kab mob ntawm cov microorgan.
Cov Ntsiab Lus Txheej Txheem
1. Lub ntsiab cai ntawm cov txheej txheem tshiab:
Tus txheej txheem tshiab yog cov txheej txheem kev kho kom zoo rau kev kho kom zoo. Nws tau txais ib qho peb-theem anoxic-aerobic-aerobic-aerobic-aerobic-a Lub pov tseg thawj nkag mus rau hauv thawj anoxic tank, qhov chaw ib puag ncig yog minducive rau kev loj hlob thiab luam ntawm cov kab mob tsis kam lees. Denitreferrificate cov kev tshuaj tiv thaiv yog nqa tawm ntawm no, siv cov organic muaj teeb meem nyob rau hauv lub pov tseg yog ib qho hluav taws xob pub rau nitrogen roj av, yog li tshem tawm nitrate nitrogen.
Tom qab, cov dej lwg nkag mus rau lub tank anoxic thib ob (lossis lub tank log tsheb). Ib puag ncig hauv lub tank no yog anaerobic nruj me ntsis, uas yog qhov txaus siab rau kev loj hlob thiab luam ntawm cov kab mob anaerobic. Anaerobic hydrolysis thiab acidification cov kev tawm tsam yog hloov ntawm soluble organic teeb meem, thiab tib lub sij hawm molecular organic, muab cov teeb meem mabicic organic ntau, muab cov teeb meem kho hluav taws xob me me rau kev kho mob aerobic.
Thaum kawg, cov neeg pov tseg nkag mus rau hauv lub aerobic tank. Ib puag ncig hauv lub tank yog aerobic, uas yog conducive rau kev loj hlob thiab luam cov kab mob nitrified thiab aerobic heterotrophic. Nitricification cov tshuaj tiv thaiv no yuav tshwm sim ntawm no los hloov ammonia nitrogen rau hauv nitrate nitrogen. Nyob rau tib lub sijhawm, dhau ntawm kev ua ntawm aerobic heterotrophic cov kab mob yog ntxiv rau cov khoom siv dej zoo ua tau raws li cov qauv kev tshem tawm.
2. MBBR cov ntsiab cai:
Tus txheej txheem MBRB yog hom tshiab ntawm cov txheej txheem tua hluav taws xob tshiab. Nws nce cov biomass thiab hom tsiaj nyob rau hauv tus reactor los ntawm kev ntxiv qee cov nyiaj ntawm cov khoom lag luam, polypropylene npas, thiab lwm yam) rau hauv lub reactor. Qhov saum npoo ntawm cov neeg tshem tawm no yog ntxhib, uas yog conducive rau cov txuas thiab kev loj hlob ntawm cov microorganisms, yog kev sib sau ntawm biofilm.
Cov kab mob me me ntawm Biofilm siv cov organic teeb meem hauv cov dej khib nyiab hauv kev loj hlob thiab cov metabolism, yog li saib tsis taus thiab tshem cov pa paug. Piv nrog cov kev ua haujlwm tsoos ua kom zoo nkauj, MBRB cov txheej txheem tau muaj ntau dua biomass thiab muaj zog dua kev ua haujlwm thiab muaj zog dua mus rau kev poob siab.
Thaum lub sij hawm muaj kev npau taws, cov buoyancy tsim los ntawm kev nce ntawm cov tub lim dej kom ntws, nce thaj tsam ib puag ncig thiab cov pa thiab cov pa oxygen. Nyob rau tib lub sijhawm, cov dej ntws no tseem txhawb nqa cov khaub ncaws sib xyaw thiab cov txheej txheem hloov pauv ntawm cov tshuaj hauv cov tshuaj ntsuab hauv cov nyhuv kho. Yog li no, MBBR cov txheej txheem muaj qhov dav thov cov kev cia siab thiab kev loj hlob muaj peev xwm loj loj hauv thaj teb ntawm kev kho dej kom huv.
Cov ncauj lus kom ntxaws piav qhia ntawm cov txheej txheem cov yam ntxwv
1. High efficiency: Tus txheej txheem tshiab yog ib hom dej phwj tuaj tshiab uas ua rau cov txheej txheem qub thiab MBBR Technology. Nws muaj qhov zoo ntawm ob qho tib si thiab muaj kev ua tiav hauv cov organic teeb meem tshem tawm, tsis kam lees thiab phosphorus tshem tawm. Los ntawm cov qauv tsim qauv thiab kev tswj kom meej, cov txheej txheem tuaj yeem ua rau cov kuab lom tawm hauv lub sijhawm luv luv xws li nitrogen thiab phosphorus hauv dej.
2. Lub zog tsis kam rau kev poob siab thauj: cov kev kho mob biofilm los ntawm cov kab mob roj biologic yog siv cov kab mob roj ntsha tau tsim los ntawm cov kab mob roj ntsha muaj teeb meem los ua kom tsis muaj teeb meem organic thiab tshem cov nitrogen thiab phosphorus thiab phosphorus thiab phosphorus thiab phosphorus thiab phosphorus thiab phosphorus thiab phosphorus thiab phosphorus thiab phosphorus thiab phosphorus thiab phosphorus thiab phosphorus thiab phosphorus. Vim tias Biofilm txuas nrog kev poob siab zoo rau cov kev ua haujlwm hauv cov organic, thiab cov txheej txheem siab muaj peev xwm tswj hwm tau zoo thiab ua kom tiav cov dej tsis zoo yog ruaj khov thiab ua tau raws li cov qauv.
3. Muaj siab yooj yim: nws muaj qib siab ntawm kev hloov pauv tau zoo thiab tuaj yeem hloov kho cov haujlwm sib txawv ntawm kev hloov kho (xws li kev sib xyaw ua ke, thiab lwm yam). Qhov kev hloov pauv no ua rau cov txheej txheem kom tau siv dav hauv nroog dej phwj tuaj thiab lwm qhov chaw ua kom tiav cov kev kho mob hauv ntau yam kev ua haujlwm nyuaj.
4. Cov hneev Me: piv nrog cov bietactors tsoos, nws muaj peev xwm muaj peev xwm ntau dua. Los ntawm kev txhim kho tus tsim thiab txhim kho kev kho mob, cov txheej txheem tuaj yeem ua tiav lub peev xwm siab dua thaum ua tau zoo dua ntawm effluent, yog li txo qhov chaw yuav tsum muaj cov chaw kho. Qhov no yog undoubtedly ib txoj kev pab loj rau cov nroog thiab thaj tsam nrog cov av ruaj khov.
Kev tswj thiab kev tswj hwm yooj yim: lub zog txhaws thiab kev npau taws ntawm MBRBR technology yog yooj yim ua haujlwm thiab tswj hwm. Vim tias muaj cov biofilms txuas nrog, lub microbial concentration nyob rau hauv lub reactor yog qhov siab thiab kev ua yog muaj zog, yog li txo lub aeration lub sij hawm thiab cuam tshuam kev siv zog. Nyob rau tib lub sijhawm, cov biofilm txuas kuj muaj peev xwm kho tus kheej thiab kho tus kheej, ua rau kev saib xyuas txhua yam yooj yim thiab yooj yim dua.
Kev Ua Haujlwm Kev Lag Luam MBBR
1. Cov tub sau xaiv: Hauv cov lej MBBR, cov yam ntxwv ntawm tus muab tub lim yog qhov tseem ceeb rau kev ua haujlwm thiab kev ua haujlwm ruaj khov ntawm cov txheej txheem. Qhov tshwj xeeb nqus, qhov tshwj xeeb thaj tsam thaj tsam, kev siv zog siv tau, kev ncua thiab ncua ntawm tus muab tub lim rau kev tsim ntawm Biofilm thiab kev kho cov txiaj ntsig kev kho mob. Yog li ntawd, thaum xaiv cov fillers, nws yog qhov tsim nyog los ntsuas thiab kho raws li cov kev siv ua kom tau raws li cov kev xav tau ntawm cov txheej txheem, txhim kho kev kho mob thiab txo tus nqi ua haujlwm.
2. Aerer System Tsim: Hauv Aerobic Tank ntawm MBRBRIC txheej txheem, yog li ua kom cov khoom siv tsis zoo, ua kom muaj kev sib xyaw ua ke, thiab txhawb nqa txoj kev tsim thiab rov ua haujlwm ntawm biofilm. Yog li ntawd, tus qauv tsim ntawm cov txheej txheem AERERERT system yuav tsum tsim nyog tau thiab muaj peev xwm hloov kho raws li cov dej tsis zoo thiab ntim cov txheej txheem.
3. Los tiv thaiv kev ntsuas nruj: Hauv cov roj ntsha ntawm MBBR cov txheej txheem, tus muab tub lim yog yooj yim rau kev ua kom muaj teeb meem. Txhawm rau kom tsis txhob muab cov tub lim, cov khoom siv xws li gratings lossis sob yuav tsum tau teeb tsa ntawm qhov hluav taws xob. Txawm li cas los xij, cov cuab yeej no tseem yuav tsum tau ntxuav kom huv tsis tu ncua los tiv thaiv txhaws. Nyob rau tib lub sijhawm, cov xwm txheej ntawm cov muab tub lim thiab kev ua haujlwm kom paub tsis tu ncua thiab cuam tshuam nrog cov teeb meem hauv lub sijhawm ntawm kev ua haujlwm MBBR.
