Lub taub dej tau zoo ntawm lub tank rau Aereration thiab nws cov cawv txiv neej rau kev kho cov tshuaj lim dej
Cov laj thawj rau kev xaiv cov dej ntws ntau:
1. Aeration efficiency: Within the water depth range of 4.0m to 6.0m, the bubbles stay in the water for a long enough time to fully contact with sewage and improve the oxygen transfer efficiency.
2. Pem Teb Chaw: Nce dej kom zoo ntxiv yuav txo qis hauv pem teb ntawm lub Aerer Tank thiab txuag cov chaw pab rau lub aeration thiab khaws cov av.
3. Cov khoom siv ua tau zoo: Kev kho cov khoom siv rau (xws li cov kws saib xyuas hluav taws me, submericible ua kom muaj kev ua haujlwm nyob rau hauv qhov tob tob tob.
4. Tus nqi tsav khiav: Cov dej tsim nyog yuav pab txo hluav taws xob kev siv thaum ua haujlwm ruaj khov ntawm lub system.
5. Cov Ntaub Ntawv Tshwj Xeeb:
(1) Oxidation Ditch: Thaum Oxidation Ditch tus txheej txheem yog saws, cov dej ua tau zoo yuav tau nce ntxiv rau 3.5 rau 4.5m.
(2) aerated roj ntsha: rau aerated roj ntsha lim, cov dej ua tau zoo yog 5m txog 7m.
Thaum tsim lub tshuab ua kom muaj Aeration, nws kuj tseem yuav tsum muaj los sib txuas ua ke cov txheej txheem tshwj xeeb, cov khoom siv geological rau kev txiav txim siab.
Qhov tob npaum li cas ntawm cov dej tob ntawm 4. {1}} m rau 6.} M muaj nyob rau hauv cov dej phwj dej?
Hauv dej phwj tuaj, cov dej ua haujlwm tau zoo ntawm lub Aerer tank feem ntau yog nruab nrab ntawm 4. {} M thiab 6. {} M. Qhov dej ntws hauv cov ntau no muaj ntau yam rau kev kho cov dej phwj dej:
1. AERATER HEEV
- Oxygen loj hloov efficiency: nce cov dej tob tuaj yeem txuas lub sijhawm nyob hauv dej, yog li kev txhim kho cov oxygen huab cua hloov kev ua tau zoo. Piv txwv li, thaum cov dej tob nce ntxiv los ntawm 0. 5m rau 4.6m, lub peev xwm oxygenation yog ho txhim kho.
- Kev Siv Zog: Txawm hais tias nce cov dej tob tuaj yeem txhim kho cov oxygen loj hloov efficiency, nws tseem yuav nce zog siv zog. Yog li ntawd, nws yog ib qho tsim nyog los nrhiav qhov sib npaug ntawm oxygen huab cua tau hloov ua haujlwm thiab kev siv zog.
2. Av nyob hauv av
- Txuag thaj av: Nce cov dej tob tuaj yeem txo cov chaw ua haujlwm ntawm lub chaw lim dej Aeration, uas yog tshwj xeeb tshaj yog rau cov cheeb tsam uas muaj av nruj.
3. Kev Kho Mob
- Cov kuab paug tshem tawm: nyob rau hauv qhov tob tob ntawm 4.} M,} m,} m,} m,} m,} m,} m,} m,} m, li kev txhim kho lub hnub nyoog tshem tawm.
- Sludge sedimentation: Qhov tsim nyog dej kom tsim nyog pab cov sedimentation thiab sib cais ntawm sludge thiab txo qis ntawm sludge.
4. Kev Ua Haujlwm ruaj khov
- Poob siab Kuj: nyob rau hauv cov dej tob ntawm 4.} M rau 6.} M, lub puab tsaig muaj zoo dua nrog kev hloov pauv dej zoo thiab ntim dej.
5. Tsim yooj yooj yim
- Kev yoog raws li cov txheej txheem sib txawv: Qhov tob tob ntawm ntau npaum li cas yog tsim nyog rau ntau yam kev kho dej phwj tuaj, oxidation ditch txoj kev, thiab lwm yam.
Tshwj Xeeb
- Oxidation Ditch: Thaum Oxidation Ditch tus txheej txheem yog saws, cov dej ua tau zoo yuav tau nce mus rau 3.5 rau 4.5m.
- aerated biological lim: rau aerated roj ntsha lim, cov dej ua tau zoo yog 5m txog 7m.
Dej Phwj Txhua Tus Qauv Tsim
1. Kev ntsuam xyuas sib txawv
(1) Lub vijtsam lub vijtsam nyob rau pem hauv ntej ntawm cov taub dej yuav tsum txiav txim siab raws li cov kev xav tau ntawm cov taub dej.
(2) Lub vijtsam vijtsam sib tw nyob rau hauv pem hauv ntej ntawm kev kho kom haum rau cov yuav tsum tau ua raws li: Qhov siab tshaj plaws yog rau kev siv tes ntxuav thiab 16 ~ 25 hli yog rau kev tu tshuab. Wastewater kev kho cov nroj tsuag kuj tseem teeb tau teeb ntxhib thiab cov ntxaij vab tshaus zoo, nrog cov ntxhib ntxaij vijtsam ntawm 50 ~ 100 hli.
(3) Cov khoom siv dej khib nyiab loj loj tuaj yeem tsim cov coarse, nruab nrab thiab cov ntxaij vab tshaus.
(4) Yog tias qhov sib txawv ntawm lub twj tso kua mis nyob pem hauv ntej ntawm lub twj tso kua mis tsis siab tshaj 25mm, tsis muaj kev tshuaj ntsuam yuav tsum tau ua ke ntawm kev kho kom zoo.
2. Vijtsam cov seem
(1) Tus nqi ntawm cov kab hlau uas muaj feem xyuam rau ntau yam
Screen Gap 16 ~ 25mm; {{2 {2}}. 1 {{{}}} ~ 0.05m3 \/ 103m3 (raptewater \/ wastewater).
Qhov screen sib txawv yog 3 {{0 ~ 5 {{4 {4 hli; 0.03 ~ 0.01m3 \/ 103m3 (Ntsuam xyuas cov khoom seem \/ Wastewater).
(2) Cov neeg noo noo ntawm cov chaw seem ntawm cov khoom seem yog feem ntau 80%, thiab cov ntom ntom yog li 960kg \/ m3.
