Kev daws teeb meem: Khoom noj khoom haus Additives Wastewater Solution 300 m³ / d Peev Xwm
Kev daws teeb meem:Khoom noj khoom haus Cov dej khib nyiab
Pib:Peb Hlis 2014
Muaj peev xwm: 300 m³/d
Qhov project Overview
Unilever lub hauv paus yog nyob rau hauv Holland, Rotterdam thiab London, UK, nws yog ib tug multinational tuam txhab uas muag koom nyob rau hauv cov khoom noj thiab tshuaj ntxuav tes.
Unilever Tianjin Industrial Park theem ob yog nyob rau hauv Tianjin tshav dav hlau Economic Zone, cov khoom muaj xws li nqaij qaib hmoov, thiab zaub xam lav, thiab txhua xyoo muaj peev xwm ntau tshaj 100 txhiab tons.
Cov nroj tsuag tsim muaj peev xwm yog 300m3 / d, Nws yog siv los kho cov dej khib nyiab uas tawm los ntawm cov txheej txheem tsim khoom, thiab cov dej ntws tawm tuaj yeem nce mus rau hauv cov qauv hauv zos.
Kev sib tw
Qhov Inlet thiab qhov hluav taws xob qhov tseem ceeb ntawm WWT cog raws li hauv qab no:
| Parameter | Chav tsev | Inlet Values | Qhov hluav taws xob muaj nuj nqis |
| COD | mg/L | 3000 | 50 |
| BOD 5 | mg/L | 1500 | 10 |
| NH4-N | mg/L | 92 | 1 |
| N (tag nrho) | mg/L | 173 | 10 |
Kev daws
Ob-theem A / O MBBR biofilm txheej txheem rau kev kho cov dej ammonia siab, thawj theem aerobic, cov kab mob nitrifying hloov cov ammonia nitrogen rau nitrate nitrogen. Tom qab ntawd cov kua ntawm O1 lub tank yuav tsum tau xa rov qab mus rau A1 txheej txheem, denitrification siv cov pa roj carbon monoxide los ntawm cov influent. Tom ntej no, ntxiv carbon qhov chaw nyob rau hauv lub tank A2 rau denitrification. Cov pa roj carbon residual tuaj yeem ua oxidation ntxiv hauv O2 tank.
Flow Chart ntawm tus txheej txheem:
Cov txiaj ntsig
Ob-theem A/O MBBR biofilm txheej txheem tau pib ua tiav nyob rau nruab nrab lub Tsib Hlis 2014. Kev ntsuas kev ua tau zoo yog qhov ua tau zoo, Biolfilm qhov chaw nyob hauv BioCell media tau loj hlob zoo heev. Thiab lub kaw lus ua tau raws li cov txheej txheem tsim tawm.
