Tom qab ua tiav kev kho dej khib nyiab, kev tsim kho bioreactor debugging feem ntau yog tsim nyog. Cov txheej txheem no pib nrog sludge inoculation. Yog li, pes tsawg tus sludge npaum li cas xam? Concurrently, qhov sib ntxiv ntawm tshwj xeeb cov dej khib nyiab kho kab mob yog yuav tsum tau rau cultivation. Yuav tsum ntxiv kab lis kev cai kab mob ntau npaum li cas?
Bioreactors siv activated sludge cultivation feem ntau siv cov sludge qhuav, activated sludge, los yog concentrated sludge. Rau cov kab mob kab mob, cov khoom xws li Gando Composite Bacteria, Nitrifying Bacteria, thiab Denitrifying Bacteria feem ntau yog siv. Ua ke ob txoj hauv kev no tuaj yeem nthuav tawm sai sai ntawm biofilm lossis biological flocs.
Sludge Debugging Methods:
1. Dried Sludge Inoculation Method (Siv Sludge los ntawm Lim Presses)
Qhuav sludge feem ntau muaj cov dej noo ntawm li 75% -80%, lub ntsiab lus ntawm cov khoom yog kwv yees li 20%.
Lub hom phiaj Mixed Liquor Suspended Solids (MLSS) concentration hauv bioreactor feem ntau yog nyob ib ncig ntawm 3000 mg / L (los yog 3 kg / m³).
Yog li ntawd, qhov tsawg kawg nkaus ntawm cov sludge qhuav yuav tsum tau ib lub cubic meter ntawm aeration tank ntim yog 3 kg / m³ / 20%=15 kg / m³.
Piv txwv:Rau 100 m³ bioreactor, qhov xav tau cov sludge qhuav yuav yog 15 kg / m³ × 100 m³=1500 kg.
Qhov tseem ceeb yuav tsum tau muab rau kev siv cov sludge qhuav tsis muaj flocculants.
Qhov zoo: Tsawg kom muaj nuj nqis, kev thauj mus los yooj yim.
Qhov tsis zoo: Feem ntau muaj flocculants, uas tuaj yeem cuam tshuam kev cog qoob loo microbial hauv bioreactor.
2. Kev cog qoob loo microbial siv cov sludge uas twb muaj lawm
Siv lub tshuab nqus tsev los thauj cov sludge- dej sib tov los ntawm cov chaw kho dej khib nyiab uas twb muaj lawm lub sludge tuav lub tank.
Feem ntau, qhov ntim ntawm cov sludge twj tso kua mis- cov dej sib tov yuav tsum yog li 60% ntawm lub tank debugged lub ntim.
Piv txwv:Rau 100 m³ tank, kwv yees li 60 m³ sib tov yuav tsum tau. Thaum lub tank ntim rau 100% muaj peev xwm (nrog dej ntxiv / muaj zog), lub hom phiaj sludge concentration yuav tsum nyob ib ncig ntawm 3000 mg / L.
Qhov zoo: Tsis muaj tshuaj nkag mus rau hauv bioreactor; ceev acclimatization.
Disadvantages: Cov ntim loj yuav tsum tau, cov nqi thauj mus los siab, lub sijhawm cog qoob loo ntev dua.
3. Kev cog qoob loo siv cov sludge siab
Qhov ntau npaum li cas yog feem ntau 5-10% ntawm tag nrho bioreactor ntim. Ib qho pib taw qhia yog ntxiv 5% (v / v) concentrated sludge, ua rau thawj zaug sludge concentration sawv cev txog 5% ntawm cov dej khib nyiab tom qab sau. Qhov no yog hais txog ib txwm nyob, concentrated sludge nrog noo noo cov ntsiab lus ze rau 100%.
Piv txwv:Rau 100 m³ bioreactor, qhov yuav tsum tau ntim ntawm concentrated sludge yog 100 m³ × 5%=5 m³.
4. Kev Siv Dej Siv Tshuaj Kho Kab Mob Kab Mob
Microbial inoculants muaj cov kab mob ua ntej -activated, siv tau.
Qhov ntau npaum li cas ntawm 500 mus rau 800 grams ib lub cubic meter ntawm qhov zoo ntawm bioreactor (xws li aerobic thiab anaerobic zones).
Cov koob tshuaj tshwj xeeb tuaj yeem sib txawv nyob ntawm cov khoom siv thiab yuav tsum tau kho raws li qhov tseeb.
Qhov zoo:Lub sijhawm cog qoob loo luv dua, tus nqi- ua tau zoo, rov ua dua tshiab, thiab tsim cov biofilm sai.
