MBBRuas feem ntau hu ua tsiv txaj biofilm reactor yog ibniaj hnub kho dej technology thiab txheej txheem.Nws tau tsim thawj zaug thaum xyoo 1980s los ntawm tus xibfwb Hallvard ntawm Norwegian University of science thiab technology.
1. Ceev ceev cov cab kuj biofilm tsim mechanism
Specific trace element vector mus rau hauv thiab tshwj xeeb nto kho txheej txheem,cov microorganisms nyob rau hauv dej ntawm cov cab kuj txuas nrog ceev ceev thiab ceev propagation ntawm kev loj hlob, biofilm tsim nyob rau hauv txawv dej tej yam kev mob, thiabbiofilm sij hawm sib txawv, feem ntau, cov ntaub ntawv biofilm xav tau 3-15 hnub.
2. Super decarburization, ammonia nitrogen tshem tawm muaj peev xwm
Carrier muab qhov chaw nyab xeeb thiab xis nyob rau kev yug me nyuam microbial, lomntau yam, vim tsis muaj sludge hnub nyoog txwv, nitrifying kab mob kuj tau loj-scalebreeding, microbial pejxeem loj yog yaj organic tebchaw thiab ammoniadecomposition.
3. Kev ua haujlwm zoo heev rau kev ua haujlwm poob siab
Muaj peev xwm ua tau zoo, nws muaj peev xwm tshem tawm cov organic teeb meem 2-5 zaug siab duauas ntawm lwm cov kev cai ib txwm muaj, siab concentrations ntawm biomass thiab ntau haiv neeg ntawm biological fungus, muaj zog tiv thaiv tej yam load peev xwm.
4. Daim ntawv thov ntawm kev hloov pauv thiab ntau txoj kev
Cov theem sib txawv tuaj yeem siv rau kev ua kom zoo nitrogen, anaerobic, anoxic txheej txheem, nkaus xwbyuav tsum tau ua cov nyhuv los ntawm kev ntxiv Juntai MBBR lim xov xwm tuaj yeem tau txais qhov txiaj ntsig zoo.
5. Kev ua haujlwm yooj yim thiab kev saib xyuas
Tsis muaj kev txhawb nqa, muab Juntai MBBR lim tawm hauv lub pas dej ncaj qha, thiab nws tuaj yeem txuag taurov qab sludge, zam sludge bulking, tuaj-up, thiab poob, yooj yim rauua haujlwm thiab tswj xyuas.
6. Lub neej ua haujlwm ntev
Los ntawm kev hloov kho cov txheej txheem tshwj xeeb, Juntai MBBR lim xov xwm muaj qhov zootsis kam, UV tsis kam, muaj zog toughness, tsis yooj yim rau kev laus thiab embrittlement,thiab nws muaj lub neej ua haujlwm ntev.
7. Deoxidation thiab phosphorus tshem tawm cov nyhuv yog qhov zoo
Vim tias cov yeeb yaj kiab lom neeg muaj peev xwm digestive muaj zog, dej ammonia nitrogentuaj yeem hloov pauv mus rau hauv nitrate thiab ammonia, qhov denitrification tuaj yeem ua taumuab tag nrho ua si rau qhov siab tshaj plaws, denitrification ntau dua. Meanwhile, biofilmloj phosphorus phosphate khoom flora dej kom huv si absorbed, thiablos ntawm cov yeeb yaj kiab lom neeg tawm mus rau hauv lub tank sedimentation thiab nws thiaj li mus rau qhovsludge tso tawm system, phosphorus tshem tawm cov nyhuv pom tseeb dua.
