MBBR: Modular Workhorse
Daim duab lub tank uas muaj ntau txhiab lub hnab yas me me-txhua qhov loj ntawm ib npib lossis ib thooj pob zeb- tsis tu ncua los ntawm dej. Qhov ntawd yog MBBR. Aeration lossis mechanical mixing ua rau cov neeg nqa khoom txav mus, thiab biofilm loj hlob ntawm lawv qhov chaw sab hauv. Cov dej khib nyiab ntws mus tas li; microorganisms noj cov pa phem. Tsis muaj sludge rov qab. Tsis muaj backwashing. Tsuas yog cov neeg nqa khoom, huab cua, thiab biology ua haujlwm.
Dab tsi ua rau MBBR qhov kev xaiv zoo rau ntau cov nroj tsuag:
• Retrofit-npaj.Koj tuaj yeem tig lub sludge phiab uas twb muaj lawm mus rau hauv MBBR los ntawm kev ntxiv cov cab kuj thiab hloov kho cov aeration- tsis muaj kev tsim kho tshiab. Qhov no yog ib qho laj thawj loj tshaj plaws uas cov nroj tsuag xaiv MBBR: nws tso cai rau koj hloov kho lub peev xwm hauv koj cov hneev taw uas twb muaj lawm.
• Tus neeg teb xov tooj-tus phooj ywg.Tsis muaj fluidization tswj. Tsis muaj recirculation twj tso kua mis kom sib npaug. Cov neeg nqa khoom tus kheej - faib nrog aeration. Yog tias tus neeg nqa khoom tawg lossis xav tau hloov, koj ntses nws tawm thiab ntxiv ib qho tshiab.
• Tsawg sludge ntau lawm.Txoj kev txuas nrog - txoj kev loj hlob ua rau kwv yees0.15-0.25 kg tshaj sludge ib kg COD tshem tawm, ho tsawg dua li cov pa activated sludge. Tsawg sludge txhais tau tias cov khoom siv dewatering me me thiab cov nqi pov tseg qis dua.
• Ua pov thawj ntawm qhov ntsuas.Ntau txhiab ntawm tag nrho - nplai MBBR kev teeb tsa ua haujlwm thoob ntiaj teb- los ntawm cov chaw dej phwj hauv nroog mus rau cov chaw tsim tshuaj lom neeg mus rau cov chaw ua zaub mov. Tsis muaj leej twg raug rho tawm haujlwm vim xaiv MBBR.
• Carrier yooj. Different carriers optimize for different jobs. A high-surface-area carrier like Juntai's MBBR 04 (>900 m² / m³) maximizes nitrification nyob rau hauv tsawg tank ntim. Ib tus neeg nqa khoom loj dua li MBBR 37 ua haujlwm ntau dua cov khoom organic nrog kev pheej hmoo qis dua.Cov neeg nqa khoom xaiv yog ib nrab ntawm MBBR tsim kev sib ntaus sib tua.
MBBR cov kev txwv yog tsim nyog paub ua ntej: nws muajme ntsis siab kam rau ua kom muaj kev cuam tshuam sai saipiv rau FBBR. Qhov tshwm sim sai sai los yog pH viav vias loj tuaj yeem cuam tshuam kev ua haujlwm biofilm ib ntus - rov qab tau siv sijhawm ntau hnub, tsis yog teev. Thiab cov neeg nqa khoom yas tuaj yeem nkag siab rau cov roj thiab roj, uas lub tsho tiv no thiab thaiv biofilm txuas.

FBBR: Tus Hnyav-Lifting Specialist
FBBR siv txoj hauv kev sib txawv kiag li. Es tsis txhob ntab yas nqa, nws siv lub txaj ntawmntom granular media- xuab zeb, activated carbon, los yog ceramic particles- uas yog fluidized los ntawm kev nce siab ntawm cov dej khib nyiab thiab huab cua. Cov khoom tseem raug tshem tawm hauv lub reactor, txhua lub lis piam coated nrog biofilm. Qhov tshwm sim yog ibextraordinarily siab biomass concentration ib chav tsev ntim: thaj chaw zoo tuaj yeem ncav cuag 3,000-4,000 m² / m³, kwv yees li 4-5 npaug ntawm cov khoom siv yas zoo tshaj plaws.
Qhov twg FBBR rub ua ntej:
• Superior shock load kuj.Cov pej xeem biofilm ntom ntom hauv FBBR ua raws li cov khoom siv roj ntsha loj heev. Thaum COD muaj zog tam sim ntawd muab ob npaug los yog cov tshuaj lom neeg nkag mus rau hauv cov kwj deg, qhov ntau ntawm biomass absorbs qhov cuam tshuam. Qhov no yog vim li cas FBBR feem ntau teev rauchemical, tshuaj, thiab petrochemical cov dej khib nyiabqhov twg influent muaj pes tsawg leeg yog unpredictable.
• Ntau dua degradation tus nqi rau recalcitrant compounds.Qhov chaw siab heev txhawb nqa tshwj xeeb microbial consortia uas rhuav tshem cov organics cov txheej txheem kev sib tw nrog. Rau siab -lub zog muaj peev xwm muaj peev xwm nrog COD ntau tshaj 10,000 mg / L, FBBR tsis tu ncua ua haujlwm zoo MBBR hauv ob qho tib si tshem tawm tus nqi thiab kev ruaj ntseg.
• Tsis tshua muaj sludge tawm los.Tshaj tawm sludge yields rau circulating FBBR configurations yog tsawg li0.12-0.16 kg VSS ib kg COD tshem tawm-kwv yees li 75% tsawg biosolids dua li cov pa activated sludge. Rau cov nroj tsuag uas them cov nqi sludge pov tseg, qhov no ib leeg tuaj yeem ua pov thawj rau kev siv tshuab.
• Cov hneev taw me me.Vim hais tias FBBR ntim ntau yam biology rau hauv ib lub ntim me me, qhov ntau thiab tsawg reactor yog me dua li qhov sib npaug MBBR lossis cov tshuab ua kom cov sludge. Hauv qhov chaw-cov chaw txwv tsis pub- qhov xwm txheej tshwm sim hauv cov nroj tsuag qub qub- qhov no tseem ceeb heev.
Tab sis FBBR los nrog kev lag luam tiag -offs. Nwsxav tau lub zog ntau duakom tswj tau cov kua dej- cov dej ntws rov tuaj yeem ncav cuag 10-12 npaug ntawm tus nqi ntws zoo. Nws thovntau tus neeg ua haujlwm txawj: fluidization tshaj tawm, lub txaj nthuav dav, thiab biofilm tuab yuav tsum tau ua haujlwm zoo los tiv thaiv kev tawm xov xwm lossis txaj txaj. Carrier particle kev paubattrition thaum lub sij hawm, xav tau kev tshaj tawm xov xwm raws sijhawm. Thiab muaj yooj yimtsawg dua tag nrho - nplai FBBR cov ntaub ntawvthoob ntiaj teb piv rau MBBR- yog li kev nrhiav cov neeg ua haujlwm paub txog thiab kev pab daws teeb meem tuaj yeem nyuaj dua.
