Tom qab kev ua haujlwm
Kev Kho Mob Hauv Nroog Kev Kho Mob (WWTP) npog thaj tsam 35,000 M² thiab tau xub tsim tsa nyob rau thaj chaw deb ntawm cov ntses ntses thiab chaw qhib. Nrog rau kev txhim kho ntawm lub nroog loj, nws yog tam sim no nyob hauv cov neeg muaj cov nplaim hluav taws xob ntau nyob hauv chaw thiab thaj chaw ua lag luam. Cov ntxhiab tsw ntawm cov dej phwj tuaj thiab lub suab nrov los ntawm cov nroj tsuag ntawm cov nroj tsuag cuam tshuam rau cov neeg nyob ze.
Cov nroj tsuag tau tsim los kho cov dej phwj tuaj ntawm 140,000 m³ / hnub. Nws qhov zoo tshaj plaws zoo yuav tsum tau ntsib chav kawm 1b ntawm Tuam Tshoj "cov pa paug tawm" cov kuab paug rau cov nroj tsuag kom loj hlob "(GB 18918-2002).
Ua ntej tau muab tso mus rau chav kho mob, cov dej khib nyiab tsis muaj kev kho mob ua ntej los ntawm cov tshuaj ntsuam coarse, thiab lub vijtsam nruab nrab, thiab lub vijtsam zoo. Kev Kho Mob Koom Haum Thawj suav nrog kev kho mob grit, ua raws li kev kho mob thib ob los ntawm cov tshuaj oxidation thiab cov lus qhia yooj yim. Thaum kawg, cov dej phwj tuaj rau sab nraud kom zoo los ntawm 1-meter txoj kab uas hla kev, ntawm qhov chaw nws ntws mus rau hauv lub thawv kaw culplill.
Kho Dua Cov Qauv Tsim
Nplai thiab effluent zoo hom phiaj
Raws li cov kev tshawb fawb nyob hauv: Cov nroj tsuag m³ nyob ntawm 140,000 milling nyob ntawm 140,000 m³ / hnub, nrog dej wastewater tau hloov mus rau lwm qhov chaw nres tsheb kom hloov mus rau lwm cov nroj tsuag kev kho. Lub effluent tsis tsuas yog tso tawm rau hauv cov dej ntws tab sis kuj rov ua kom dej nyob hauv cov pas dej nyob ze. Yog li ntawd, lub effluent yuav tsum ua raws li ob chav kawm 1A ntawm GB 18918-2002 thiab cov khoom siv hluav taws xob ib puag ncig ib puag ncig "(GB / T 18921-2002). Tsis tas li ntawd, los tiv thaiv Eutrophication hauv pas dej, tus qauv hauv chav kawm nyob hauv "Sab saum toj Cov Qauv Dej Zoo" (GB 3838-2002).
Txheej Txheem Flow Tsim
Qhov kev xaiv xaiv "AAO + MBR" txheej txheem rau cov nroj tsuag hloov kho. Cov txheej txheem kev kho mob sludge siv lub tshuab hluav taws xob txuag hluav taws xob kom txo cov ntsiab lus noo nyob rau hauv qab no 80%, thiab sludge tau xa mus rau lub nroog lub nroog sludge sludge chaw kho mob.
Txhawm rau txiav txim siab qhov kev ua tau zoo thiab cov kev khiav haujlwm, kev hloov kho tshiab tau ua rau cov qauv siv biowin software raws li kev ua kom tiav cov qauv zom (ASDM), nrog kev siv hluav taws xob ua kom zoo thiab siv tshuaj lom neeg.
Zuag qhia tag nrho tsim
Tus nroj tsuag muaj tsawg cheeb tsam ntawm kwv yees li 33,000 m². Peb khaws nws cov qauv uas twb muaj lawm xws li cov tswj hwm thiab tswj lub tsev. Cov qauv ntau lawm uas tsis tau ntsib cov kav dej lim dej lossis cov qauv tsim kho, oxidation ditch, sludge dewatering cheeb tsam thiab chav tswj hwm, tau hloov kho mus rau ntau qib sib txawv.
Piv txwv li, peb tau tsim cov MBR chav tsev los hloov cov kev tso tsheb hlau luam ntxiv, kev tso tsheb hlau luam yeeb yaj kiab, cov chav siv tshuaj txhuam hniav, nrog rau kev siv tshuaj khib nyiab. Cov cuab yeej siv no coj nws cov dej phwj tuaj rau cov qauv coj kom muaj dej rov qab.

Cov khoom siv submersible tau nruab rau sab hauv lub tank kom ntseeg tau tias qhov kev ua tau ruaj khov ua haujlwm los ntawm kev sib xyaw thaum lub sij hawm sludge dewatering. Lub tank yog tseem nruab nrog ultrasonic sludge theem meter '6} Lub sij hawm teev cov sludge chav nyob hauv chav nruab nrab ntawm chav nruab nrab thiab thaj chaw dewatering. Cov pub rau sludge twj tso kua mis tuaj yeem nres thaum lub sludge qib yog dhau lawm, thiab cov khoom nres ua haujlwm thaum qib qis.
Sludge dechening regenation
Yav dhau los, lub tshuab ziab muaj sia tau siv rau kev kho kom zoo. Tom qab kev txhim kho siv lub tshuab ua kom zoo dua qub tau ntsib qhov kev xav tau, tab sis cov teeb meem tsw cuam tshuam nrog sludge tsis tuaj yeem tsim nyog tau hais. Yog li ntawd, centrifugal dewatering tshuab yog cov hau los hloov lub tshuab ziab khaub ncaws siv. Plaub lub ntsej muag tav kev teeb tsa dewatering tshuab yog tsim, nrog peb hauv kev siv thiab ib qho ua haujlwm rov qab, ua haujlwm rau 12 teev nyob rau ib hnub. Txhua lub tshuab muaj lub peev xwm (q) ntawm 60 m³ / h thiab lub zog (n) ntawm 66 kW.
ODOR tswj system
Vim tias muaj av qeeg ntawm qhov kev kho kom dej huv, txoj haujlwm saws rau ntawm - lub tsev kawm ntawv tsw qab, nrog rau 6 qhov chaw raug xaiv:
1. Cov ntxhiab tswj System 1: Hom phiaj tsis muaj ntxhiab los ntawm qhov chaw ua hauj lwm, siv tsob ntoo-
2. Cov ntxhiab tswj System 2: Tsim los ntawm sludge dewatering chav thiab sludge cia tank, nrog ib tsob nroj-
3. Cov ntxhiab tswj tau 3: Lub hom phiaj tsw ntawm Anaerobic / anoxic tso tsheb hlau luam. Txhua lub tank muaj qhov muaj peev xwm tag nrho ntawm 13,000 mp / h. Vim tias qhov chaw txwv nyob hauv chav tso tsheb hlau luam, ob qho muaj peev xwm ntawm 6,500 m³ / h, tau nruab rau hauv ob chav sib cais hauv chav dej. Ob lub units qhia ib qho kev tso tawm ib qho kev tso tawm thiab tuaj yeem ua haujlwm ywj pheej.
4. Kev siv tshuaj lom neeg tswj hwm 4: Tsim rau ob MBR cov kev tso tsheb hlau luam, kho cov tso tsheb hlau luam me me, kho cov pa roj ntsha
Kev sib tham txog cov ntsiab lus ntsuab tsim hauv cov nroj tsuag kom muaj dej tsim
1. AQuantion siv ntau yam nroj tsuag kom tsim multi {1} {{2} {{2} {{2} {{2} {{2} {{2} {{2} {{2} {{2} {{2} {{2} {{2} {{2} {{2} {{2} {{2} {{2} {{2} {{{2} {{2} - Filling ecological cuam tshuam los ntawm zej zog.
Thib ob, cov nroj tsuag nyob rau hauv qhov chaw nruab nrab ntawm thaj chaw kawm, thiab peb tau teeb tsa cov dej ceramic dej ntawm nws lub ntsiab nkag. Cov dej kho tau rov qab siv rau kev tsim kho kom zoo rau cov neeg muaj kev paub txog kev txuag dej thiab kev tiv thaiv ib puag ncig.
2. Nyob rau hauv cov nqe lus ntawm toj roob hauv pes thiab ntsuab chaw tsim qauv, peb lub ntsiab lus ntawm "txuag cov khoom siv" kev tsim kho cov ntsiab lus ntawm "daim txhuam cev nroog". Aquastens txoj kev tshaj tawm tshiab xws li cov ru tsev ntsuab, ntsug ntsuab thiab ib puag ncig cov phooj ywg chaw nres tsheb ntau.
Peb kuj tau them rau oxidation ditch nrog av los tsim ib qho chaw hauv nroog "Mini Park" uas qhia txog tus txiv neej thiab xwm. Tus "Daim txhuam cev nroog" lub tswvyim tuaj yeem siv los ua cov khoom siv thermal rwb thaiv tsev rau cov tsev thiab tshuaj tua hluav taws xob thiab ua qias tuaj.
Dej Zoo Kho Kom Zoo
Tom qab txoj haujlwm txhim kho kom zoo dua qub, kev kho kom zoo dua qub ua haujlwm tau pib ua haujlwm thaum lub Kaum Ob Hlis 2017.
Cov ntsiab lus ntawm Kev Tshawb Xyuas Qhov Kev Ntsuam Xyuas
Nyiaj txuag tsaws
Qhov project npog tag nrho cheeb tsam ntawm 54,991.54 m², nrog rau lub teb ∙ / (hnoos qeev ntawm cov av thiab kwv yees li 170 lab CNny.
ZIAB TAWM
Qhov project kho hluav taws xob kev siv hluav taws xob yog 0.46 kWh / m³, piv rau cov txheej txheem ntawm daim nyias nyias muaj kev kho mob uas twb muaj lawm, sawv cev rau cov kev siv hluav taws xob uas tsim nyog. Lub Zog Zog Txuag Nyiaj tsawg kawg 2 lab KWH, nrog tus nqi hluav taws xob txuag tau kwv yees li 1.6 lab CNny.
Kev tiv thaiv dej
Qhov project lub project effluent, tom qab kev kho siab, tuaj yeem xaiv tau rov qab ua pas dej dej thaum lub caij nplooj zeeg thiab lub caij ntuj no, txo kev cia siab rau cov kais dej. Qhov no txoj hauv kev tuav tau txog 4 lab mais ntawm cov dej txhua xyoo.
Cov Khoom Txhuam Khoom
Qhov qauv tsim tawm qhov hloov chaw uas twb muaj lawm (piv txwv li, lub tsev tseem ceeb, oxidation cheeb tsam, thiab txuag ib puag ncig 80 lab CNY hauv kev nqis peev. Kev siv PAC thiab cov pa roj carbon thiab cov pa roj nyob qis dua 30 mg / l, piv rau ib puag ncig 50 mg / u nyob rau hauv cov phiaj xwm zoo sib xws, txuag tau kwv yees li 20 mg / l. Cov nyiaj khaws txhua xyoo nyob rau hauv PAC thiab cov pa roj teeb tag nrho ib ncig ntawm 1,000 tons lossis 2.5 lab CNY.
Cov txiaj ntsig ib puag ncig
Qhov kev nce qib zoo tau txo cov kuab paug paug tawm mus rau hauv cov dej ntws. Ntawm kev kho mob nplai ntawm 140,000 moll / d, nws tau kwv yees los ntawm cov pa paug tshiab: codcr los ntawm 4,740 t, s, tn los ntawm 960 t, thiab tp los ntawm 140 t.
Cov Kev Pab Cuam Tshuam Ecepor
Qhov project muab tag nrho cov kev ua kom tiav- Cov suab nrov tsw qab thiab hloov nws mus rau hauv lub neej zoo heev rau cov neeg nyob ze.
