Cov txheej txheem Unitank
Lub unadank system ua haujlwm zoo sib xws rau aTriple-Ditch Oxidation Ditch, Featuring peb qhov kev sib txuas ua ke nrog cov khaub ncaws uas muaj kev sib xyaw nrog cov pa thaiv thiab sib xyaw ua ke. Wastewater tuaj yeem nkag mus rau ib lub tank, thaum lub sijhawm sab nraud tso rau ob qho ntxivaeration / sedimentation zones(nruab nrog weirs / decanters thiab sludge tso cov khoom siv). Lub chaw nres tsheb thauj mus los tas li.
DhauSpatiotemporal tswj, cov txheej txheem ua tiavaerobic, anoxic, thiab anaerobic tej yamHauv ib lub voj voog ib zaug thaum tswj hwm qhov taub tas mus li. Tsis zoo li pa sbr, unitankifies ua haujlwm nrog:
- Kev ua haujlwm ruaj ruaj ua haujlwm txuas ntxiv (tsis muaj dej ntws ntawm cov qib dej)
- Tsis muaj sludge recirculation yuav tsum tau
- Kev hloov kho cov khoom noj muaj txiaj ntsig zoo ntawm inlet muab

1.Cov yam ntxwv tseem ceeb ntawm unadank
Hybrid Tsim Cov Lus Zoo
- Hydraulic Ruaj Khwv: Qib dej tas mus li txo cov kav dej / li qub, txo tus nqi ua haujlwm.
- Compact hneev taw: 1 / 3-1 / 2 qhov chaw ntawm oxidation ditches (tsis muaj thawj / theem nrab clmifiers lossis ras tshuab).
- Saj zawg zog aeration: Txhawb cov aerators saum npoo (tsau weirs txaus, tshem tawm cov ntab ntab).
- Kho kom meej cov khoom noj muaj txiaj ntsig: Qhia meej sib cais ntawm anaerobic / anaerobic / ntsuas anaSes (vs. SBr's sib tshooj sib tshooj).
2.Cov Nyiaj Tau Los
- Sib txuas zog ntawmSBR, kev pab cuam ua haujlwm, thiabOxidation PlhuavThaum kov yeej lawv cov kev txwv:
- Nruam taub (vs. sbr txoj kev sib quas ntus)
- Kev sib sib zog nqus-tank tsim kev ua haujlwm siab
- Puv Automation nrog cov cuab yeej siv tsawg kawg (1 / 6-1 / 4 cov neeg ua haujlwm thiab cov neeg oxidation)
- Nqi txuag: Peev peev peev ≈50% ntawm oxidation ditches.

Cov txheej txheem dat-hiat
Cov txheej txheem dat-itia (thov Aerüritt Tank-sensmittentent aerator tank) yog ib qho kev hloov kho ntawm SBRisty, muaj ob qho kev sib tw ua ke:
- DAT (thov kom muaj Aeration Aeration):: Pub dawb txuas ntxiv thiab aerated.
- ITO (COUNDITTENTENTENT AFERT TANK): Ua tau Cyclic li cateration, kev sib luag, decranting, thiab sludge nkim.

1.Cov yam ntxwv tseem ceeb ntawm dat-iat technology
(1) txhim kho ruaj khov & load tsis kam
- DAT muabKev sib koom tes sib luag hydraulicLos ntawm nruam inflow / aberation, txhim kho kev ruaj khov.
- SiabMLSS kev siabthiabKev Ncua Sij Hawm NcaujHauv ob qho tib si dat thiab Iotia bast resilisence rau cov organic / toxic poob siab.
- Media tau hloov kho tauPab txhawb kev ua kom tsis txhob muaj cov koom haum.
(2) Compact & Screified Tsim
- Sib xyawAeration-sedimentationtshem tawm thawj / theem nrab clmary thiabslude rov qab tshuab.
- Aerobically ruaj khov sludgeYuav tsum muaj tsuas yog thickening / dewatering (tsis muaj cov zom).
(3) Kev hloov kho cov khoom noj kom haum
- Kho ITiaAeration / kaw lub sijhawmtsim kev hloovaerobic / anoxic / anaerobic tej yamrau kev ua tau zooN & p tshem tawm.
(4) nqi & ua haujlwm ua haujlwm
- Faib phab ntsaNruab nrab ntawm dat-hiat txo cov nqi kev cai lij choj thiab hneev taw.
- Tsawg dua decantersxav tau vs. pas rau sbr.
- Txo Kev Xav Tau: Nruam dat aation txiav blower muaj peev xwm ~ 30% vs. sbr.
- Yooj Yim TEEB: Tsis muaj qhov tso rau li qub

MSBR cov txheej txheem
TusHloov Seastring Batch Reactor (MSBR)Ua ke ntawm cov txiaj ntsig ntawm kev ua kom tau zoo sludge thiab sbr tshuab. Nws ua haujlwm ntawm aKev Siv Dej DejNrog ib leeg-tank, ZOV-comporter sib tsim, tshem tawm qhov xav tau rau interconnecting kav dej, twj, thiab li qub ntawm ntau cov tso tsheb hlau luam.
