Taw qhia rau SBR
TusSubncing Batch Reactor (SBR)yog cov txheej txheem lim dej ua kom haum siv cov txheej txheem roj ntsha (aeration, sterling, thiab decanting) hauv aib tanklos ntawm timed mus txog. Tsis zoo li chang-ntws lub tshuab, sbr ua haujlwm hauvcov pob zeb, muab cov khoom siv tau yooj yim thiab ua tau zoo.
Kua khawbLub Peev Xwm Kho Vaj Tsev:
(1) BOD & COD TSHWJ XEEB
(2) Cov khib nyiab (SS) tshem tawm
(3) nitrification & denitrication
(4) phosphorus tshem tawm
Cov Txheej Txheem Tseem Ceeb
(1) Hybrid hydraulic tsoom fwv
- Sib txuasPlug-Flow(Sijhawm-raws cov kev xav tau) thiabTiav-Sib tovzoo.
- Tswj tausiab suprude conctrationnrogCov Khoom Siv Hluav Taws Xob Rog Organic, enabling:
✓ Hnyav Hnyav-thau khoom tiv thaiv
✓ Siv kho kom zoo ntawm kev lom / high-zog muaj dej khib nyiab
(2) Ncua Sij Hawm Tsawg Hnub nyoog & microbial yooj yim
- Ntev sludge hnub nyoog txhawb pab ntau haiv neeg microbial.
- Hloov tauaerobic / anoxic / anaerobic phasesHauv ib qho tank tso cai:
✓ Ib txhijN tshem tawm(nitrricification-denitricalification)
✓ P muab tshem tawmntawm Paos (phosphorus-accumulating muaj sia)
(3) Built-in extor nyhuv
Tsis kam lees ua kom meej meej supient + hloov redox tej yam kev mob:
✓ Txhawb nqa filamentous bulking (Svi ~ 100)
✓ Ua kom ruaj khov kho slude daws
(4) Zoo tagnrho li qub
- Tsis muaj qhov ua kua rau / aeration thaum lub sijhawm ua kom tiav →Piav kom meej-dawb.
(5) Kev Cog Lus & Nqi-Ua Tau
- Sib xyaw ua ke Aeration / qhia meej →30-50% Cov hneev taw me meCov tshuab hluav taws xob.
- Txuag:
✓ 20-40% cov nqi peev(Tsis muaj cov twj tau hais meej / hloov dua twj)
✓ Cov nqi ua haujlwm(Tsawg heev pretricement yuav tsum tau)
(6) ANDATION AUTTER
- Khoos phib tawj-tswj kev ntsuas computer (sau / kev sib tw / decant) ntawm:
✓ Lub Cev Muaj Zog Li Qub
YEFENTRENS QIB
✓ Flowers
- Pab kom txhijKev ua haujlwm tsis saib.
Cov yam ntxwv ua hauj lwm
(1)Muaj zog tsis kam mus poob siab- Tus nqi kho tau kom haum rau kev yoog raws kev hloov pauv zoo hloov pauv.
(2)Zoo sludge bulking tswj- Cov kev xaiv siab los ntawm kev sib txawv ntawm cov organic sib xyaw nrog kev sib txawvAnoxic / Oxic mob suppresses filamentous bacentia kev loj hlob.
(3)Kev ua cov microbial siab rau kev ua haujlwm refractory degradation- Kev hloov kho lub sijhawm ua haujlwm tsim cov allicic tseem ceeb class thiab cov pa oxygen hloov kev ua haujlwm thaum lub sij hawm sib tw.
(4)Cov txheej txheem yooj yim nrog cov peev txheej qis / ua haujlwm ua haujlwm- Tshem tawm thawj lub ntsiab lus meej, kev tso tsheb hlau equalis, thiab theem nrab clarifiers thaum xav tau tsis muaj sludge rov qab system.
(5)Kev lag luam yooj yim thiab kev tswj hwm- Nta qib siab siab.
(6)Yooj Yim Sludge Kev Kho Mob- Mus txuas ntxiv sludge hnub nyoog pab txhawb kev ruaj khov tsis muaj cov zom.
(7)Effluent zoo heev- Cov kev ua haujlwm tau kho ua tiav ua tiav cov kev tshem tawm nitrogen thiab phosphorus tshem tawm.
Txawv ntawm hloov kho sbr thiab classical sbr
Tus txheej txheem SBR system siv cov haujlwm ib zaug reactor hauv kev tsim cov theem-reass-decant-decant phases. Cov kev ua tiav no yuav tsum tau ua ntau reactor units rau kev kho kom nruj nruam kev kho, nce cov txheej txheem kev nyuaj, ua haujlwm nyuaj, thiab hneev taw.
Txhawm rau hais txog cov kev txwv no, hloov cov txheej txheem SBR tau tsim kho. Cov lus hauv qab no sib piv cov ntsiab lus tseem ceeb ntawm lub tswv yim sbr variants piv rau classical sbr.
