Yuav ua li cas xam cov diffuser kom muaj nuj nqis hauv lub tank terration?

Hauv kev kho dej phwj tuaj, lub Aerer tank yog ib qho ntawm cov kev kho mob loj hauv cov txheej txheem kev kho mob biochemical.Aeration DiffusersYog ntsia rau hauv qab ntawm lub tank, uas ua kom pom huab cua (oxygen) rau hauv dej los ntawm kev rhuav tshem cov khoom siv hauv cov dej phwj tuaj hauv cov dej phwj.

Thaum peb tsim kho cov lej ntawm cov diffusers zoo, peb tuaj yeem tswj hwm cov kev ua haujlwm nyob ruaj khov ntawm cov txheej txheem kev kho mob biochemical thiab kom ntseeg tau tias cov dej ua kom zoo dua cov qauv. Yog li, peb yuav ua li cas thiaj ua tau qhov no? Kab lus no yuav qhia kom meej yuav ua li cas los xam cov diffusers uas xav tau nyob rau hauv lub tank lub tsev muag khoom, muab cov kev taw qhia rau koj thaum tsim qauv lossis kho dua tshiab rau lub Aeration Aeration.

Hauv kev kho dej phwj tuaj, kev teeb tsa ntawm cov diffusers yuav cuam tshuam rau kev ua haujlwm ua haujlwm thiab kev nqis peev ntawm cov kev kho mob tag nrho. Qhov no yog tshwj xeeb nyob hauv cov hauv qab no:

1. Txhawb txoj kev loj hlob ntawm cov microorganisms:Nyob rau hauv cov txheej txheem dej phwj teb, cov kab mob me me ua kom dawb huv cov dej tsis zoo los ntawm decomposing organic paug hauv cov dej phwj. Tus txheej txheem no yuav tsum muaj txaus oxygen, uas feem ntau muab los ntawm txhaj cua (oxygen) npuas rau hauv dej los ntawm cov lej tsim nyog ntawm cov diffusers.
2. Zam kev siv cov khoom pov tseg:Tsim kom muaj cov qauv ntawm cov diffusers kom muaj peev xwm tswj tau qhov ntau npaum li cas ntawm Aeration, sib ntsib cov kev kho mob thaum tsis txhob siv lub zog tsis tsim nyog. Nyob rau hauv kev qhib cov txheej txheem sludge, yog tias cov pa oxygen (ua) hauv dej qis dua 0. 5mg / l, nitrification cov tshuaj tiv thaiv nyob rau hauv lub dej phwj tuaj. Thaum nws tshaj 4mg / l, nws yuav ua rau muaj cov khib nyiab ntawm oxygen.
3. Tiv thaiv sludge tso nyiaj:Kev sib txuam ua ke tuaj yeem ntseeg tau tias cov oxygen yog tusyees faib rau hauv lub tank ua haujlwm kom muaj aeration, zam kev hypoxia hauv zos lossis hypoxia. Nws tseem tuaj yeem txhawb nqa tus neeg raug tshem tawm thiab sib xyaw ntawm kev ua haujlwm sludge, tiv thaiv nws los ntawm kev tso rau hauv qab ntawm lub tank thiab tig mus rau hauv "tuag sludge".
4. Lub neej ua haujlwm lub neej ntawm lub system:Thaum tus naj npawb ntawm cov diffusers tsis yog teeb tsa kom zoo, qee qhov sib txawv tuaj yeem ua rau muaj kev thauj ntau dhau. Txawm li cas los xij, yog tias peb ua rau peb raug faib cov lej ntawm cov diffusers, txhua tus kws kho mob tuaj yeem ua haujlwm nyob hauv kev ua haujlwm ib txwm muaj. Thiab peb kuj tuaj yeem txuag tau tus nqi ntawm cov khoom siv hloov nyiaj.

1. Kev txiav txim siab cov pa oxygen (O₂ thov, kg / h)

Cov pa oxygen yog lub hauv paus rau xam tus naj npawb ntawm cov diffusers. Feem ntau, nws tuaj yeem xam raws li lub bod (biochemical oxygen thov) lossis cod (tshuaj lom cov tshuaj oxygen) ntawm cov dej qias. Ntawm no peb pom zoo kom siv cov mis phem:

Cov pa oxygen=bod * 1.2(1.2 yog qhov kev nyab xeeb, uas tuaj yeem hloov kho raws li cov txheej txheem tiag tiag).

2. Txiav txim siab cov pa oxygen hloov kev ua haujlwm (sote,%)

Cov pa oxygen hloov efficiency (sote) yog hais txog lub peev xwm ntawm tus autator los hloov cov pa rau hauv cov dej ua ke, feem ntau qhia raws li feem pua. Cov mis yog:Sote=× (×} s - /}}} θ ece}}})

Parameter piav qhia:

: Cov yam ntxwv zam tsis zoo rau kev kho cov coefficient (0. 6 - 0. 9)

: Supinity correction coefficient ({0}}}}}. 0)

θ:Kub coefficient (1.024)

C_: Cov pa oxygen ntawm cov dej huv ntawm 20 degree (9.08 mg / l)

C_L: Qhov tseeb yaj oxygen concentration (1. 0}} mg / l)

T:Dej Kub (5 ~ 35 Qib)

Hauv kev siv cov kev siv, ntau yam yuav cuam tshuam rau cov Sote, qhov loj me thiab kev teeb tsa kub, txaus, huab cua siab thiab qib cua.

3. Xam cov naj npawb ntawm cov diffusers

Cov khoom muaj pa oxygen ntawm ib tus aerator ib txwm muab los ntawm cov chaw tsim khoom (kg o₂ / h). Tom qab txiav txim siab cov pa oxygen thiab cov pa oxygen hloov kev ua haujlwm, tus naj npawb ntawm cov diffusers yuav tsum tau muab suav tau. Cov lej suav yog:

Tus naj npawb ntawm cov diffusers=pa oxygen / (oxygen thov ntawm ib tus aerator ib leeg * oxygen hloov kev ua haujlwm).

Piv txwv tias cov khoom muaj pa oxygen ntawm ib tus aerator

4. Layout thiab cua ntim faib

(1) Tusyees Layout Diffusers Diffusers:Tom qab xam cov lej ntawm cov diffusers, peb kuj yuav tsum paub meej tias cov diffusers yog tusyees faib nyob rau hauv lub tank rau kev siv cov pa oxygen. Qhov no tuaj yeem tsim raws li daim phiaj lossis nplhaib qauv.

(2) laij tag nrho cov cua ntim kev xav tau:Nyob rau lub sijhawm no, peb yuav tsum xam cov cua ntim tag nrho raws li tus naj npawb ntawm cov diffusers thiab huab cua ntim xav tau ntawm ib tus aerator. Tom qab ntawd, raws li tag nrho cov cua ntim kev xav tau thiab lub siab poob ntawm cov kab ke, thiab lwm yam, xaiv lub cleuple zoo. Thaum kawg, peb tsim cov raj xa hluav taws xob kom ntseeg tau tias cov cua sab nraud tuaj yeem hloov tau thauj txhua tus aerator.

1. Tsim kev txhawb nqa rau AERERATER system:AQuareust muaj pab neeg txuj ci tshaj lij uas tuaj yeem suav cov lus qhia tsis zoo rau cov neeg yuav khoom raws li cov neeg siv khoom raws li cov neeg yuav khoom raws li cov neeg siv khoom raws li cov neeg yuav khoom raws li cov neeg siv khoom raws li cov neeg yuav khoom raws li cov neeg siv, xws li Bod, Cod, Ammonia nitrogen cov ntsiab lus thiab lwm yam kev ntsuas.

2. Kev Ntsuam Xyuas thiab Kev Ntsuas:Peb yuav ua cov ntawv tshawb fawb thiab kev ntsuas ntawm kev ua kom muaj Aerer tiag tiag ntawm cov neeg siv khoom thiab cov haujlwm ua haujlwm ntawm cov khoom siv tsis muaj kev txwv. Los ntawm kev kuaj hauv thaj chaw thiab cov ntaub ntawv tshawb xyuas, peb tuaj yeem hloov kho cov phiaj xwm kom ua tau zoo rau cov kev npaj ntawm lub aeration aeration kom txhim kho cov pa oxygen hloov kev ua haujlwm.

3. Cov lus qhia rau kev txhim kho cua cua thiab kev siv hluav taws xob:Raws li cov ntaub ntawv ua haujlwm tiag tiag, peb muab cov neeg siv khoom nrog cov lus qhia rau kev ua kom zoo ntawm kev ua tau zoo. Qhov no suav nrog kho tus naj npawb ntawm cov diffusers hauv kev ua haujlwm thiab ua kom zoo ua haujlwm ntau zaus ntawm cov kiv cua. Tag nrho cov ntawm no yuav tau ua raws li kev ua ntej ntawm kev kho cov nyhuv kho thiab txo kev siv hluav taws xob.

4. Txhim kho thiab commissioning kev taw qhia:AQUsasust tseem muab kev teeb tsa kev txhim kho thiab cov lus qhia. Peb yuav pab koj kho cov ntsuas thiab txheej txheem ntawm cov diffusers kom cov khoom lag luam ua haujlwm hauv qhov kev mob zoo tshaj plaws.

5. Tom qab kev pab muag khoom txhawb:Los ntawm cov chaw taws teeb saib xyuas, peb muab cov neeg siv khoom lag luam uas muaj cov neeg siv khoom lag luam ntev tom qab kev soj ntsuam kev ua haujlwm thiab kev kuaj mob ntawm kev npaj kho vaj tsev. Thaum cov khoom siv ua tsis tiav, peb yuav teb sai sai kom ntseeg tau cov haujlwm ruaj khov ntawm koj lub enteration system.

Kev ua kom zoo ntawm lub aeration system hauv lub nroog dej phwj dej kho tsob nroj

 

Tom qab:Cov kev kho mob ntawm qee lub hauv paus lim dej tua yog 10, 000 m³ / d. Tus thawj Aeration system ntawm cov nroj tsuag muaj qhov roj oxygen tsawg thiab siv hluav taws xob siab, thiab tsis tuaj yeem kho cov dej phwj tuaj.
• Tshuaj:Raws li cov dej muaj xwm txheej zoo, peb tau muab cov kev thov oxygen. Tsis tas li ntawd, peb tau txais ntau duadisc diffusersthiab ua kom zoo rau txheej txheem ntawm cov diffusers.
• tshwm sim:Tom qab rov kho dua tshiab, cov oxygen hloov kev ua haujlwm nce los ntawm 30%, kev siv hluav taws xob tsawg zuj zus los ntawm 15%, thiab effluent tau ua rau cov qauv txo cov qauv.

Aeration Scheme rau cov kev siv hluav taws xob siab-siab rau kev siv cov nroj tsuag kom huv

 

Tom qab:Lub Cod ntawm cov dej khib nyiab hauv cov nroj tsuag tshuaj tau ntau dhau, thiab lub cev tsis muaj pa tsis tuaj yeem muab pa oxygen txaus. Qhov no tau coj mus rau qhov kev txwv tsis pub muaj kev ua haujlwm ntawm kev ua haujlwm sludge, thiab kev kho dej khib nyiab tsis ruaj khov.
• Tshuaj:Peb sawsRaj diffusersRau nws thiab kho kom zoo rau tus kiv cua configuration. Qhov no tau siv los txhim kho cov nyhuv ntawm cov pa hauv dej.
• tshwm sim:Tom qab rov kho dua tshiab, cov pa oxygen nyob rau hauv lub aerer tank tau muab faib rau 20%, thiab lub kaw lus yuav ua haujlwm tau ntau dua.

Raws li tus kws tshaj lij hauv kev kho dej phwj tuaj, peb muaj kev nkag siab tob ntawm cov txheej txheem pov tseg kom tob thiab muab koj cov kev paub dav dav. AQUANUP tau cog lus rauCustomizing ua tau dej kho cov dej kho tau zooRau koj raws li koj cov kev xav tau tiag tiag, ua kom koj lub cev ua haujlwm ntau dua.

Tiv Tauj PebTam sim no xav paub ntxiv txog yuav ua li cas peb cov kws tshaj lij cov kws tshaj lij tuaj yeem txhim kho koj cov txheej txheem kev kho kom muaj kev kho kom zoo.
