Txawm hais tias ib txwm siv SBR thev naus laus zis muaj ntau qhov zoo, nws muaj kev txwv tsis pub muaj kev cuam tshuam txuas ntxiv, cov dej ntws tsis tu ncua, thiab loj - daim ntawv thov engineering. Yog li ntawd, cov kws tshawb fawb thiab cov kws tsim qauv tau tsim cov txheej txheem SBR txhim kho kom zoo dua qub rau cov kev xav tau sib txawv ntawm cov dej khib nyiab. Kab lus no qhia txog tsib txoj haujlwm tseem ceeb ntawm SBR txhim kho.
I. ICEAS Txheej Txheem – Nruam Cyclic Extended Aeration System
ICEAS (Intermittent Cyclic Extended Aeration System)
Cov yam ntxwv ntawm tus txheej txheem: Ib cheeb tsam ua ntej - cov tshuaj tiv thaiv (tseem hu ua cheeb tsam xaiv) yog ntxiv rau qhov kawg ntawm SBR ib txwm muaj, hloov cov kev ua haujlwm los ntawm kev cuam tshuam cuam tshuam mus rau qhov cuam tshuam tsis tu ncua thiab cuam tshuam tsis sib xws.
Kev txhim kho: Qhov ua ntej- thaj tsam tshuaj tiv thaiv zoo txhim kho sludge daws kev ua tau zoo, thiab hom kev cuam tshuam txuas ntxiv yog tsim nyog rau kev kho mob nrog cov dej loj.
Main Disadvantages:
(1) Lub sijhawm tuav hydraulic yog qhov ntev, thiab kev kho mob yuav tsum tau ua kom zoo dua qub;
(2) Cov txheej txheem sedimentation cuam tshuam los ntawm kev cuam tshuam txuas ntxiv, uas tuaj yeem ua rau muaj kev cuam tshuam hydraulic yooj yim; Yog li ntawd, lub influent ntim yuav tsum tsis txhob loj heev.
II. CAST txheej txheem - Cyclic Activated Sludge Technology
CAST (Cyclic Activated Sludge Technology)
Cov txheej txheem CAST, tseem hu ua CASS lossis CASP, yog ib qho ntawm cov txheej txheem SBR uas tau siv dav.
Cov yam ntxwv ntawm cov qauv: Lub reactor muab faib ua peb thaj chaw ua haujlwm:
(1) Biological Selective Zone (anaerobic lossis facultative anaerobic mob);
(2) Facultative anaerobic Zone;
(3) Aerobic Zone.
Kev khiav hauj lwm Mechanism: Thaum lub sij hawm influent thiab aeration theem, sludge los ntawm aerobic cheeb tsam yog xa rov qab mus rau ib tug biological xaiv cheeb tsam, tag nrho siv cov sludge los txhim kho sludge settling kev ua tau zoo. Lub facultative anaerobic zone ua raws li qhov tsis zoo rau cov dej zoo thiab kom muaj nuj nqis.
Cov txiaj ntsig tseem ceeb: Qhov chaw xaiv lom neeg muaj txiaj ntsig zoo inhibits sludge bulking, txhim kho kev ruaj ntseg, thiab txhim kho sludge daws teeb meem.
III. DAT- txheej txheem IAT – Nruam Aeration-Intermittent Aeration Series Process
DAT-IAT (Thov Aeration Tank - Sib Nqus Aeration Tank)
Txheej Txheem Txheej Txheem: Muaj ob qhov txuas txuas hauv series: DAT (Nruam Aeration Tank) thiab IAT (Intermittent Aeration Tank).
Kev Ua Haujlwm Mechanism: Dej ntws tsis tu ncua. Cov dej khib nyiab ua ntej nkag mus rau hauv lub tank DAT rau kev kho mob ua ntej, tom qab ntawd ntws mus rau hauv IAT tank, qhov twg aeration, sedimentation, kua dej, thiab tshem tawm cov sludge ntau dhau ua tiav. Ib feem ntawm cov sludge ntau dhau los ntawm IAT tank rov qab mus rau DAT tank.
Lub ntsiab zoo:
(1) Ua haujlwm siab rau kev poob siab;
(2) Kev siv siab ntawm cov tshuaj tiv thaiv tank;
(3) Muaj zog adaptability, yooj yim khiav lag luam, thiab tsis tshua muaj infrastructure peev.
IV. UNITANK Txheej Txheem - Integrated Activated Sludge System
UNITANK (Unified Tank)
Cov Txheej Txheem Txheej Txheem: Lub kaw lus muaj peb txoj kev sib tshuam sib txuas, txhua qhov nruab nrog lub tshuab cua lossis qhov chaw aeration thiab kev sib xyaw ua ke.
Kev khiav hauj lwm Mechanism: Peb txoj hauv kev hloov pauv ua haujlwm raws li lub tank aeration thiab sedimentation tso tsheb hlau luam ntawm ob qho kawg. Lub kaw lus ua tiav cov khoom siv hluav taws xob txuas ntxiv thiab txuas ntxiv effluent. Txawm hais tias kev ua haujlwm tag nrho yog tas mus li, ib tus neeg tso tsheb hlau luam ua haujlwm sib cuam tshuam nrog cov khoom siv hluav taws xob thiab cov dej ntws tawm.
Core Advantage: Los ntawm kev hloov pauv ntawm ntau lub tso tsheb hlau luam, nws daws qhov teeb meem ntawm kev cuam tshuam tsis tu ncua thiab effluent nyob rau hauv cov tsoos SBRs, ua rau nws tshwj xeeb tshaj yog haum rau loj - cov dej khib nyiab kho cov dej num uas yuav tsum tau muaj cov dej ntws mus tas li.
V. MSBR Txheej Txheem – Hloov Kho Sequencing Batch Reactor
MSBR (Modified Sequencing Batch Reactor)
Txheej Txheem Txheej Txheem: Ua haujlwm ib zaug - tank, ntau- qauv tsim kom ua tiav kev ua haujlwm tsis tu ncua ntawm cov dej tsis tu ncua.
Cov Qauv Txheej Txheem: suav nrog lub tank anaerobic, lub tank anoxic, lub tank aerobic, thiab ob lub SBR tso tsheb hlau luam (lub tank tshuaj tiv thaiv thiab lub tank effluent).
Kev Ua Haujlwm Kev Ua Haujlwm: Kev sib xyaw cawv rov ua haujlwm tshwm sim nyob rau hauv lub tank aerobic, thiab muaj txiaj ntsig txuas ntxiv txawm tias thaum lub sij hawm effluent, ua tiav qhov kev ua haujlwm tsis tu ncua thiab kev ua haujlwm tsis tu ncua.
Core Advantage: Zoo heev nitrogen thiab phosphorus tshem tawm efficiency, thiab kev khiav dej num tas li kom tsis txhob muaj teeb meem poob taub hau tshwm sim los ntawm cov dej hloov pauv hauv SBRs ib txwm muaj.
VI. Cov ntsiab lus ntawm Cov Txheej Txheem Txhim Kho
Tsib txoj kev txhim kho SBR tau hais los saum toj no txhua tus muaj lawv tus kheej lub hom phiaj:
ICEAS - Ua kom muaj kev cuam tshuam tsis tu ncua los ntawm thaj chaw ua ntej - cov tshuaj tiv thaiv, haum rau kev ua haujlwm me me rau nruab nrab- teev;
CAST - Txhim kho sludge daws kev ua tau zoo los ntawm thaj chaw xaiv lom neeg, siv dav tshaj plaws;
DAT-IAT - Txhim kho kev tiv thaiv kev poob siab thiab kev siv lub tank los ntawm kev sib txuas ntawm ob- tank series;
UNITANK - Ua tiav cov khoom siv hluav taws xob txuas ntxiv thiab cov dej ntws los ntawm kev hloov pauv ntawm ntau lub tso tsheb hlau luam;
MSBR - Ib lub tank nrog ntau qhov sib txuas, ua haujlwm tsis tu ncua dej, zoo tshaj plaws rau kev tshem tawm nitrogen thiab phosphorus.
Qhov tshwm sim ntawm cov txheej txheem txhim kho no tau ua rau SBR cov txheej txheem thev naus laus zis ua tiav, muaj peev xwm hloov kho rau ntau yam kev kho dej khib nyiab los ntawm me me mus rau qhov loj, los ntawm qhov yooj yim mus rau qhov nyuaj.
