Lub txaj txav biofilm reactor (MBBR), raws li kev kho lim dej lim dej ua haujlwm, cia siab rau cov neeg nqa khoom uas haum. Cov khoom lag luam zoo tuaj yeem txhim kho cov kab ke ntawm cov organic thauj khoom muaj peev xwm thiab kho effecticiency thaum ua kom muaj kev ruaj khov ruaj khov. Cov kab lus no qhia txog cov qauv kev xaiv rau MBRR cov nqa khoom thiab muab cov ncauj lus kom ntxaws ntawm tsib lub teb chaws ntawm aquat MBR cov neeg nqa khoom.
I. Kev xaiv cov qauv rau MBRR cov neeg nqa khoom
1. Biofilm Symptomment Performance
- Nto Roughness: ntau dua qhov chaw roughness pab cov organic teeb meem khaws cia, txhawb kev loj hlob microbial thiab biofilm tsim.
- Hydrophilicity: Hydrophilic chaw yog qhov tsim nyog dua rau microbial txuas thiab kev loj hlob.
- Electrostatic kev sib cuam tshuam: Txij li cov kab mob me nyuam feem ntau tsis zoo them, cov neeg nqa khoom nrog cov chaw zoo tau them ntau dua rau cov microbial.
2. Cov yam ntxwv Hydraulic
- Ntsej zog: Yuav tsum ze rau ntawm cov dej (zoo tshaj plaws: {{}}. 97-1.03 g \/ cmÃ}. 973 g \/ hack) kom ntseeg tau yooj yim txav nrog dej ntws.
- Thaj chaw thaj chaw tshwj xeeb: thaj chaw loj tshwj xeeb txhawb nqa cov biomass tuav tseg.
- Cov qauv thiab qhov loj me: tsim kom zoo rau kev ua tiav kom ua tiav cov dej zoo ntws dynamics.
3. Kev kho tshuab lub zog thiab tshuaj ruaj khov
- Puas Ua Ntej: Muaj Kev Ntsuas Siab Txhua Yam Kom Ua Tau Zoo Lub Neej.
- Tshuaj lom neeg inertness: Yuav tsum yog-biodegradable thiab corrosion-resistant.
Ii. Tsib Qhov Zoo Tshaj Plaws ntawm Aquatrasust MBR cov neeg nqa khoom
A. Optimized cov qauv txheej txheem saum npoo
- Tshwj xeeb tsim cov npoo roughness tseem ceeb ceev nrawm nrawm nrawm.
- Txhim kho cov pa tsw qab tshem tawm kev ua tau zoo, ua kom tau txais kev kho kom zoo dua.
- Muab cov chaw txuas ntxiv rau cov microorganisms, nce biomass.
B. Scientific Tus Nqi Kev Kawm Tau Zoo
- Zoo them cov nplaim hluav taws xob txhawb kev txuas ntawm cov kab mob sib piv.
- txhim kho cov nqi tiv thaiv biochemical, txhim kho kev kho kom tau zoo.
- Txo qhov tsim cov microbial flocs, txo qis sludge cov kev pheej hmoo ntau lawm.
- Pab tswj cov txheej txheem kev ruaj khov, txo cov zaus kom tu thiab cov nuj nqis.
C. Zoo Hydrophilicity
- Hydrophilicity zoo tshaj plaws yog qhov zoo rau microbial kev loj hlob thiab biofilm tsim.
- Cov dej saum npoo ua yeeb yaj kiab txhim kho kev hloov oxygen, txhim kho cov oxidation oxidation efficiency.
- Hloov tau rau ntau yam dej ua kom zoo, suav nrog:
- High-concentration organic wastewater
- oily wastewaterater
- Wastewater nrog cov khib nyiab loj
D. Qhov Porosity Tsim
- Porosity ranges los ntawm 70% txog 95%, ntsib kev kho mob ntau yam kev kho mob.
- High porosity muab ntau thaj chaw thaj chaw ntau rau Biofilm txuas, ua rau nws haum tshwj xeeb rau:
- high-concentration organic wastewater kev kho mob
- Cov ntawv thov yuav tsum muaj cov biomass
E. Ua kom ceev ceev tswj
- Qhov ceev ceev yog nruj me ntsis tswj nyob rau hauv qhov kev pom zoo ntawm 0. 97-1.03 g \/ cm³.
- kom ntseeg tau qhov zoo tshaj plaws buoyancy nyob rau hauv dej rau kev ua kua tau zoo.
- Txo kev siv hluav taws xob thiab cov nqi ua haujlwm thaum txuas tau yooj yim.
III. Tag
Qhov ntsuas tseem ceeb tshaj plaws rau kev xaiv cov tsheb MBR zoo MBR yog biofilm thiab cuam tshuam nrog kev kho mob biofilm thiab kev kho mob.
Aquattust MBR cov neeg nqa khoom, los ntawm tsib tus qauv txheej txheem kev txhim kho-muab kev tswj hwm, ruaj khov, ruaj khov, thiab cov nqi kho tau zoo rau kev kho kom tiav. Cov Nta no pab tau kev yoog raws li ntau cov xwm txheej ua haujlwm nyuaj thaum txo cov nqi kev ua haujlwm thiab tu ua haujlwm, ua rau lawv xaiv qhov zoo tshaj plaws rau niaj hnub MBBRY.
