Kev daws teeb meem:Cov dej khib nyiab
Pib:Peb Hlis 2016
Muaj peev xwm: 10,000 m³/d
Sembcorp Industries yog lub zog ua haujlwm, dej, dej hiav txwv, thiab pab pawg txhim kho nroog ua haujlwm thoob tsib lub tebchaws thoob ntiaj teb. Nrog cov chaw nyob ib ncig ntawm 11, 000 megawatts ntawm tag nrho cov hwj chim muaj peev xwm thiab ze li ntawm 9 lab cubic meters ntawm dej ib hnub twg nyob rau hauv kev ua hauj lwm thiab nyob rau hauv kev tsim kho, Sembcorp yog ib tug ntseeg siab muab kev pab cuam ntawm lub tseem ceeb zog thiab dej daws rau ob qho tib si industrial thiab hauv nroog cov neeg muas zaub. . Nws tseem yog tus thawj coj hauv ntiaj teb hauv kev lag luam offshore thiab marine engineering, nrog rau lub npe tsim khoom lag luam hauv nroog loj. Hauv Suav teb, cov khoom siv hluav taws xob Sembcorp tau nthuav tawm ntau dua 12 lub xeev, lawv tau tsim kaum tawm cov chaw kho dej hauv cov chaw ua haujlwm tshuaj lom neeg, thiab muab cov kev pabcuam dej khib nyiab rau cov tuam txhab tshuaj.
Sembcorp Qidong Dej Lub Tuam Txhab yog BOT qhov project hauv Suav teb, muab cov txheej txheem ua tiav ntawm cov dej phwj tuaj kho thiab cov kev pabcuam muaj nqis ntxiv rau cov tuam txhab roj, tshuaj, thiab tshuaj hauv chaw ua haujlwm. Cov cuab yeej siv dej phwj zoo thiab cov cuab yeej siv tau txais yuav hauv txoj haujlwm no tom qab ua tiav, Lub Nroog Dej ib puag ncig tau txhim kho zoo heev thiab nws tseem tiv thaiv cov dej hauv zos dej zoo thiab kev sib npaug ntawm ecological.
Kev sib tw
Lub peev xwm tsim yog 10,000m3 / d, qhov muaj txiaj ntsig thiab muaj txiaj ntsig ntawm kev kho mob lom raws li hauv qab no:
| Qhov project | Chav tsev | Muaj hwj chim | Cov dej ntws tawm |
| COD | mg/L | 450 | 90 |
| BOD | mg/L | 330 | 16.5 |
| TN | mg/L | 70 | 14 |
| NH4-N | mg/L | 45 | 4.5 |
| TP | mg/L | 5.5 | 3.3 |
| SS | mg/L | 360 | 30 |
| PH | -- | 6-9 | 6-9 |
| Kub | degree | 10-40 | -- |
Kev daws
Cov txheej txheem tseem ceeb ntawm cov dej phwj tuaj kho tau txais cov thev naus laus zis uas ua ke nrog kev kho mob lom neeg thiab tshuaj lom neeg ozone oxidation, cov txheej txheem ntws tau qhia raws li hauv qab no:
BioCell MBBR Media
MBBR Media muab ob txoj haujlwm tseem ceeb: Qhov chaw tiv thaiv sab hauv qhov chaw tso cai rau biofilm txuas thaum txhawb nqa cov kab mob heterotroph / autotroph. Qhov thib ob, ntau lab daim ntawm MBBR media ua raws li cov cuab yeej shearing ntawm chav kawm huab cua npuas kom ua kom cov pa oxygen hloov mus.
Aeration Grid
Lub tshuab stainless hlau ntxhib npuas aeration yog ua haujlwm los muab cov xov xwm tshem tawm sib npaug thoob plaws hauv lub reactor thaum muab lub zog sib xyaw uas yuav tsum tau ua kom cov laus biofilm los ntawm thaj chaw sab hauv ntawm cov xov xwm thiab tswj cov pa oxygen uas xav tau los txhawb txoj kev kho mob lom.
Cov txiaj ntsig
Tom qab 2 lub hlis ntawm kev ua haujlwm thiab kev ua haujlwm, cov dej ntws tawm tuaj yeem txhawb nqa cov txheej txheem, cov dej phwj tuaj kho tau nkag mus rau kev lag luam ua tiav.
Kev daws teeb meem 2: Kev daws cov dej khib nyiab 28,800 m³ / d Muaj peev xwm
Kev daws teeb meem:Cov dej khib nyiab
Pib:Lub Xya Hli 2014
Muaj peev xwm: 28,800 m³/d
Hais txog MBBR Technology
Lub ntsiab yam ntxwv ntawm Moving Bed Biological Reactor (MBBR) configurations yog tias tsis muaj sludge recycle los ntawm ib tug thib ob clarifier. MBBR yog qhov tseem ceeb ib qho yooj yim, ib zaug dhau los ntawm cov txheej txheem, qhov twg tag nrho cov kev ua lom neeg muaj nyob rau ntawm cov khoom siv biomass. MBBR feem ntau yog ua raws li cov khoom sib cais xws li cov lus qhia thib ob lossis DAF, kom cais cov khoom siv bio-solids uas ua rau hauv cov txheej txheem los ntawm qhov kawg effluent. Qhov txiaj ntsig tseem ceeb ntawm MBBR yog qhov muaj zog thiab yooj yim txo cov kuab paug (soluble BOD lossis COD, NH4 +, thiab lwm yam), nrog cov txheej txheem tsawg tsawg, siv cov hneev taw me me thaum piv rau cov qauv kev kho mob aerobic. MBBR feem ntau yog siv rau cov ntawv thov kev lag luam siab lossis rau cov chaw yooj yim-rau-ua haujlwm hauv nroog.
Kev sib tw
Lub peev xwm tsim ntawm WWTP yog 1,200m3 / h, cov ntaub ntawv hauv qab no qhia tau hais tias muaj kev cuam tshuam thiab cov dej tsis zoo ntawm cov nroj tsuag:
| Qhov project | Chav tsev | Muaj hwj chim | Cov dej ntws tawm |
| COD | mg/L | 1200 | 60 |
| BOD | mg/L | 400 | 10 |
| CI- | mg/L | 16500 | -- |
| Ca2+ | mg/L | 6000 | -- |
Kev daws
Tom qab MBBR txheej txheem, rau kev degradation ntxiv ntawm cov organic teeb meem refractory.
Cov txiaj ntsig
MBBR Influent COD 80 ~ 100mg / l, Effluent COD 50 ~ 60mg / l, tshem tawm tus nqi ntau dua 30%.
