1. Core Mechanics ntawm MBBR Kev Kho Dej Num
CovMBBRtxheej txheem leverages mbbr biofilm cab kuj - cov khoom yas me me (feem ntau 10-25mm) nrog thaj tsam siab (500-1200 m² / m³) - uas ncig dawb hauv mbbr tso tsheb hlau luam. Raws li cov dej khib nyiab ntws los ntawm lub reactor, cov kab mob microorganisms colonize cov cab no, tsim cov biofilm tiv thaiv uas zom cov organic pollutants, ammonia, thiab nitrogen. Tsis zoo li cov tshuab ua yeeb yaj kiab, cov txheej txheem txav txaj bioreactor ua kom muaj kev sib cuag tsis tu ncua ntawm biomass thiab cov khoom paug los ntawm kev tswj aeration lossis sib tov.
2. Kauj Ruam -los ntawm - Kauj Ruam MBBR Kev Ua Haujlwm
Theem 1: Biofilm Development
Tsis pub dhau 2-4 lub lis piam, cov kab mob txuas mus rau mbbr cov xov xwm, tsim cov biofilms. Kev ntxhib los mos ntawm biochip mbbr cov neeg nqa khoom nrawm nrawm.
Theem 2: Lub voj voog kho dej khib nyiab
Influent nkag
Cov dej tsis huv nkag mus rau mbbr bioreactor.
01
Media Fluidization
Aeration systems tshem tawm mbbr lim xov xwm, ua kom dej khib nyiab ntau tshaj -kev tiv tauj biofilm.
02
Pollutant Degradation
Biofilms nqus thiab zom BOD / COD (txog 95% kev ua haujlwm zoo).
03
Kev tshem tawm cov zaub mov
Nitrifying kab mob hloov NH₄⁺ rau NO₃⁻; anoxic aav pab kom denitrification.
04
Theem 3: Kev sib cais ntawm cov dej ntws tawm
Cov dej kho tau tawm los ntawm cov ntxaij vab tshaus sieve ( khaws cov xov xwm ), thaum cov khoom siv biomass ntau dhau los rau kev ua cov sludge.
3. Cov Cheebtsam Ua Haujlwm Ua Haujlwm Pabcuam MBBR
Cov lus: Cov ntsiab lus tseem ceeb ntawm MBBR System rau Kev Kho Dej
| Cheebtsam | Muaj nuj nqi | Specifications |
|---|---|---|
| Biofilm Carriers | Microorganism nyob | HDPE / PP, 500-1200 m² / m³ cheeb tsam |
| Aeration Grid | Oxygen supply & media suspension | Zoo- npuas diffusers, 0.3-0.5 Nm³/h/m³ |
| Retention Screens | Media ntim | Perforated SS304, 1-5mm qhib |
| Mixers (Anoxic Zones) | Media ncig tsis muaj oxygen | Tsawg-Speed submersible agitators |
4. Hybrid Configurations Txhim khu kev ua tau zoo
Anaerobic MBBR
Rau siab - muaj zog muaj effluent; ua haujlwm tsis muaj oxygen.
IFAS Systems
Muab tshem tawm biomass nrog mbbr thev naus laus zis los txhawb nqa nitrification.
MBBR-MBR kev koom ua ke
MBR membranes polish effluent for reuse (>99% turbidity tshem tawm).
5. Vim li cas MBBR Outperforms Conventional Methods
Adaptability
Tuav cov khoom hloov pauv (txog li 3x peak flows) yam tsis muaj biomass washout.
Hneev taw
50-70% me dua li cov nroj tsuag sludge.
Kev kho qis
Tsis muaj sludge recirculation lossis clarifiers xav tau.
