1. Kev tswj cov MBR qhov tshwm sim
Hauv daim duab membrane BorkSactor, kev ua haujlwm ntawm daim nyias nyias kev sib sib cais tau zoo ib yam li cov kev ua yeeb yam sib cais. Cov ntsiab lus tswj tau muaj zog yog cov khoom siv tsis zoo, cov membrane tau daws, ntsuas kub, kev khiav hauj lwm zoo, MLSS, thiab lwm yam.
1) kub
Daim duab membrane Berioactor system yuav tsum tau ua haujlwm ntawm 15 degree -35 degree. Feem ntau, daim nyias nyias flux nce nrog kev nce ntawm qhov kub, uas yog feem ntau vim tias lub cawv sib xyaw ua ke tom qab qhov kub nce ntxiv, yog li txo cov kev tso cai.
2) Kev khiav hauj lwm siab
Thaum cov yam ntxwv ntawm kev ua kom zoo li cov cawv sib xyaw ua ke tsis tau hloov pauv, Daim duab membrane Flux nce nrog kev nce siab; Tab sis thaum lub siab nce rau qee tus nqi, uas yog, kev pom zoo ua rau lub siab ua kom pom kev zoo, tab sis ua rau lub ntsej muag txuas ntxiv mus, tab sis ua kom tsis txhob ua rau lub ntsej muag ua kom tsis txhob muaj qhov tseeb Lub transmembrane siab qhov txawv ntawm cov submerged MBR yuav tsum tsis pub tshaj 0. 05mpa.
3) DUAB XWV PASYGEN
Duav oxygen yog ib qho tseem ceeb cuam tshuam rau kev tshem tawm cov nyhuv organic. Tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv phosphorus tshem tawm thiab nitrogen tshem tawm, kev tswj hwm lub siab ntawm cov pa oxygen yog qhov tseem ceeb. Hauv cov txheej txheem sib txawv Bieteactor, cov kua ua kua roj ua kua aerobic, anoxic thiab anaerobic seem hauv cov bioreactor hauv ntau hom. Kev tswj hwm ntau yam ntawm kev ua nyob rau hauv txhua ntu ntawm tshooj yog: {{{{}}}. 2mg / l thiab 0.5mg / l, Thiab cov oxygen conctration conctration yuav tsum tsis pub tsawg tshaj 2mg / l.
4) Membrane Kev Sib Tw Ntaus
Qhov cuam tshuam ntawm Membrane nto Flow tus nqi thiab siab rau Membrane Flux muaj kev sib cuam tshuam. Thaum lub siab yog tsawg, Daim membrane Flain Flow tus nqi muaj qhov siab me me, thiab thaum lub siab Flux txaus tus nqi muaj cov nyhuv nto cuam tshuam rau daim nyias nyias. Raws li daim membrane Flow Flow tus nqi nce, daim nyias nyias flux kuj nce, tshwj xeeb tshaj yog thaum lub siab yog qhov siab. Qhov no yog vim tias qhov nce hauv membrane cov dej ntws tawm hauv dej ntws thiab txo cov dej tso tawm ntawm cov pa phem rau ntawm daim nyias nyias; Ntawm qhov tod tes, qhov nce ntws mus tus nqi tuaj yeem ua kom muaj kev yooj yim hloov pauv, txo cov tuab ntawm cov ciam teb txheej, thiab txo cov kab zauv polarration. Tsis tas li ntawd, kev txiav txim siab ntawm kev cuam tshuam ntawm daim nyias nyias kev tshaj tawm rau ntawm daim nyias nyias qab cov khoom siv. Thaum lub sludge concentration yog tsawg, tshuaj membrane permication nce linearly nrog membrane Doocity. Txawm li cas los xij, thaum sludge concentration yog siab, tom qab daim ntawv me me ua kom tsis muaj nqis, thiab tus nqi ntawm kev nce ntawm daim nyias nyias flux txo qis. Rau cov mbr sab nraud, cov kev ua haujlwm yuav tsum tau tswj hwm ntawm qhov qis qis thiab txaus siab npaum li ntau tau, thiab daim nyias nyias muaj zog yuav tsum tau tswj hwm thaum 3m / s. Qhov no tsis yog tsuas yog pab kom tswj tau cov dej siab ua rau kev saib xyuas thiab saib xyuas cov ntaub nyias nyias thiab hloov ntawm daim nyias nyias.
5) mlss
Lub ntsej muag ci ntsa iab hauv cheeb tsam aerobic (tank) ntawm submerged MBR yuav tsum tau tswj hwm ntawm 3000mg / l ~ 20000mg / l. Feem ntau hais lus, ntawm ib qho kev sib cav sib ceg hauv lub cev, thaum sludge concentration, vim yog qhov yooj yim tso rau ntawm daim nyias nyias txheej los tsim cov txheej sludge tuab, ua rau muaj kev nce siab kev tawm tsam thiab txo qis hauv membrane Flux. Txawm li cas los xij, qhov sludge conctration nyob rau hauv cov kua pub tau tsis tshua muaj, thiab kev tsis muaj zog, uas yuav ua rau muaj zog tsis muaj zog, uas yuav ua rau muaj zog ntawm cov organic cov teeb meem Nyob rau hauv supernatant ntawm cov kua sib xyaw thiab yooj yim adsorbed los ntawm membrane nto, ua rau muaj kev tiv thaiv flux tsis tshua muaj. Yog li ntawd, ib qho kev xav tsis thoob rau hauv cov kua pub yuav tsum tau tswj hwm. Siab dhau los yog qis dhau yuav txo cov dej flux.
6) PHEEJ NQI
Tus nqi ntawm tus nqi ntawm daim membrane bioractor yuav tsum yog 6-9.
2. MBR Biochemical Cov Txheej Txheem Tswj
Thaum lub inlet dej kub yog qis dua 8 degree, kev ua haujlwm ntawm kev ua haujlwm sludge yog cuam tshuam rau qee yam. Nyob rau lub sijhawm no, chav ntim effluent yuav tsum yog txo kom paub tseeb tias cov organic muaj teeb meem nyob rau hauv cov dej phwj tuaj hauv cov tshuaj tiv thaiv tank, yog li ua kom zoo dua qub. Qeeb rau cov membrane thaiv.
Nyob rau hauv lub caij thaum qhov kub hloov dheev, nws yog qhov tshwj xeeb tshaj yog qhov pom tau zoo. Yog tias cov khoom siv effluent zoo, qhov tsim nyog effluent ntim yuav tsum raug txo thiab lub sijhawm Aeration yuav tsum nce ntxiv.
Thaum lub sijhawm ua haujlwm qub, cov tshuaj tua kab mob thiab cov tshuaj tua kab mob uas inhibit cov metabolism hauv cov kab mob me me yuav tsum raug zam los ntawm kev sib xyaw ua ke rau hauv Bioreactor. Tiv thaiv txoj kev siv roj ntsha ib txwm muaj ntawm cov microorganisms hauv cov khoom siv los ntawm kev puas tsuaj, ua rau tsis zoo ntawm effluent.
Thaum cov dej phwj muaj ntau cov hluavtaws hluav taws xob lossis lwm cov tshuaj foaming, muaj cov ua npuas dej loj yuav tshwm sim hauv daim nyias nyias bioreactor. Lub sijhawm no, cov dej txau siv tuaj yeem siv los daws cov teeb meem, tab sis tsis txhob ntxiv defoamers muaj cov tshuaj oily rau cov tshuaj tiv thaiv tank tshem tawm cov npaus. Silica gel series defoamers kuj tsis pub siv. Silica gel series defoamers yog adsorbed ntawm daim nyias nyias, uas yuav ua kom nrawm dua qhov nce ntawm cov nyias nyias thiab ua rau tus kheej los thaiv. Nyob rau lub sijhawm no, nws yog qhov nyuaj kom rov qab lub siab sib txawv txawm tias cov kua siv rau kev ntxuav, thiab daim nyias nyias yuav tsum tau hloov.
Lub pob zeb MBR cov txheej txheem yuav tsum tawm qee qhov nyiaj ntawm cov seem uas tsis tu ncua. Tus nqi ntawm sludge tso tawm tuaj yeem txiav txim siab raws li slude daws cov cawv, cov organic thauj khoom ntawm cov hnub nyoog ua haujlwm lossis lub hnub nyoog sludge.
3. Tswj MBR MRBRANE POB ZAUB THIAB TU
Membrane pa tau qias neeg yog qhov tshwm sim uas raug tshem tawm cov lus thiab cov colloids hauv cov ntses membrane, ua rau tus membrane pores thaiv. Thaum daim nyias nyias los ntawm kev sib cuag nrog cov kua muaj kuab lom, thiab kev kos duab ntawm lub solute thiab tus membrane pib hloov pauv cov khoom plig membrane. Rau microfiltration membranes, cov nyhuv no tsis pom tseeb, feem ntau ntawm kev sib cav sib ceg thiab pore thaiv ntawm cov nplais; Rau ultrafiltration, yog tias cov khoom siv membrane tsis raug xaiv, qhov cuam tshuam yog loj heev, thiab nws tuaj yeem raug txo los ntawm 20% rau 40% piv nrog thawj cov dej ntshiab flux. Tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej ntawm kev ntws tsawg thiab ntau dua cov txheej txheem solubility rau ntawm daim nyias nyias, ua rau muaj kev ywj pheej, ua rau muaj kev ywj pheej, ua rau muaj kev txo qis nyob rau hauv daim nyias nyias permeability. Yog li ntawd, daim nyias nyias ua haujlwm hauv lub xeev no yuav tsum tau ntxuav tom qab siv los kho nws qhov kev ua tau zoo.
