Tam sim no, tsis muaj lub teb chaws raug cai lossis txheej txheem kev lag luam rau kev siv rau kev tsim qauv thiab suav ntawm MBBR txheej txheem hauv cov kav dej phwj tuaj.
Qhov thib peb ntawm" Cov Khoom Siv Dej thiab Cov Dej Tsim Dej Qhia&"; Volume 5 muab qhov tsis sib xws
(1) CovLub tank MBBR cov tshuaj tiv thaivyog tsim nrogtsis pub tsawg tshaj 2 lub cell.
(2) Sau ntimyog xam rawsntim ntimthiabnruab nrab txhua hnub cov dej phwj tuaj.
Rau cov dej phwj hauv tsev lossis cov kav dej hauv nroog uas muaj cov kav dej phwj hauv tsev, MBBR ntim tau tuaj yeem yog 1.0 ~ 1.4kgBOD5/(m3 · d).
(3) Rau lub hom phiaj ntawm kev tshem cov pa roj carbon monoxide nkaus xwb, kev thauj khoom siab tuaj yeem txiav txim siab. Thaum muaj cov txheej txheem nitrification tom ntej, yuav tsum siv lub nra qis:
Thaum lubthauj khoom siab(75 ~ 80% BOD tshem tawm tus nqi), BOD thauj khoom ib chav ntawm tus neeg nqa khoom tuaj yeem yog> 20g/ (M2 · d)
Hauv qabib txwm thauj khoom(80 ~ 90% BOD tshem tawm tus nqi), chav tsev nto BOD thauj khoom ntawm tus nqa khoom tuaj yeem yog 5 ~ 15g/(m2 · d)
Hauv qabtsawg load(ua ntej nitrification), chav tsev BOD load tuaj yeem yog 5g /(M2 · d).
(4) Thaum sivrau denitrification
Covua ntej-denitrification tus nqi feem ntau yog 0.15 ~ 1.0g/(m2 · d),
Covncej-denitrification, thaum cov khoom siv carbon tau ntxiv ntau dhau, qhov siab tshaj plaws nitrate cov khoom thauj thaj chaw tshem tawm cov pa roj carbon sab nraud tuaj yeem ntau dua 2g/(m2 · d).
(5) Qhov tshwj xeebthaj chawntawm qhov xaiv cov muab tub lim yog feem ntau 200 ~ 600m2/m3, thiab qhov ntim feem ntau yog 35%~ 60%.
(6) Feem ntau, covncov ntws tshaj tawmtsis ntau dua 35m/h, txwv tsis pub cov ntim yuav sib sau ua ke.
(7) HRT ntawmhypoxic tshuajMBBR feem ntau yog 1.0 ~ 1.2h,
HRT ntawmaerobicMBBR feem ntau yog 3.5 ~ 4.5h.
(8) Nyob rau hauvdenitrificationMBBR, ualub zog ntawm agitatortuaj yeem xam raws 25 ~ 35W/m3.
