Tseem muaj anaerobic MBBRS uas tau siv tau siv rau kev kho kom muaj dej khib nyiab. [5] Ib tsab xov xwm 2019 piav txog kev sib txuas ntawm anaerobic (Mthanogenic) MBR nrog Aerobic MBR uas tau thov kev kho mob hauv nroog kom muaj kev lag luam hauv biogas.
Biofilm cov cab kuj tuaj yeem thauj khoom ua tiav Bioractors ntawm qhov tsawg kawg nkaus ntawm 25% V / v rau tag nrho ua haujlwm ntim ntawm lub tank. Yav tom ntej nthuav ntawm biofas ™ MBBRA MBLAS ™ MBBRAs tuaj yeem ua tiav los ntawm cov biomass cov nqa khoom muaj li 75% v / v thiab nce cov cua mov.
Tau txais MBRB med daim ntawv sau tag nrho, koj tau txais tus nqi tsawg kawg nkaus hauv kev nqis peev nws, thaum lub sijhawm ua haujlwm, nws txij nkawm, thiab suav nrog nws hloov pauv thaum ua tau. Cov khoom tiav MBRR cov khoom siv muab cov txheej txheem txhim khu kev qha ntau thiab muaj zog ruaj khov ua haujlwm txheej txheem.
Raws li peb tau sib tham saum toj no, tus qauv tsim thiab cov duab ntawm MBRB Bio Media Cov tsheb thauj khoom yuav ua rau cov khib nyiab puas efficiency thiab ua hauj lwm. Media cov cab kuj nrog cov duab sib txawv, txiav cov duab ua kom zoo li muaj ntau thaj tsam hauv kev ua kom muaj kab mob kab mob thiab txhawb nqa biosolid tawg.
Muaj ib sab cib ntawm qhov hluav taws xob ntawm lub tank yuav ntxiv kev ua tau zoo dua thiab yog qhov tsim nyog tau muab tso rau hauv cov cable yas los ntawm kev rhuav cov txheej txheem ntawm kev npau taws.
Muab nyob rau hauv 1 m3 super sacks thiab xa khoom ntawm pallets kom yooj yim ntawm kev thauj mus los. Cov cab kuj tuaj yeem thauj khoom rau hauv cov pob thiab tso tsheb hlau luam ntawm ib lub tsheb ciav hlau lossis lub crane.
Siv MBRB me me yog qhov zoo tshwj xeeb vim tias cov me me ua qhov chaw tsawg, yog ib qho yooj yim los tswj thiab zom zom kom zoo. Cov kab mob me me ntawm cov xov xwm kuj tseem tuaj yeem hloov kho kom hloov pauv ntawm cov nyiaj thiab hom pov tseg hauv dej. Txawm hais tias MBBBREY yuav tsum muaj qee qhov kev soj ntsuam, lawv muaj kev lom zem rau tus kheej txaus.

1. Muab cov khoom tso tawm
-Thaum tus muab tub lim ntxiv, saib seb puas muaj tsub zuj zuj zus, thiab nres pub mis thaum nws tshwm sim. Tos rau hnub tom qab mus txuas ntxiv saib ua ntej ntxiv.
-Thaum txhaws cov muab tub lim, siv cov kev sib tham, thiab a cateration tuaj yeem txuas ntxiv thaum hmo ntuj, tab sis lub caij nplooj zeeg lub suab yuav tsum tau txo.
-Thaum khiav rau 24 teev, txuas ntxiv mus pub dej rau 2-3}}}}}}}}}}}}}}}}}}} Tom qab khiav rau 48 teev, saib xyuas zaj duab xis ntawm kev muab tub lim rau cov tub lim dej, thiab kuaj cov pa oxygen yaj hauv pas dej. Nws yog qhov zoo tshaj plaws kom nws nyob ib ncig ntawm 1. {5-2. {{Mg / l. Tom qab 72 teev ntawm kev ua haujlwm, hu rau lub inlet dej thiab maj ntxiv nws rau cov qauv yuav tsum tau ua. Raws li cov kev tshuaj xyuas cov dej tsis zoo ntawm cov inlet thiab qhov hluav taws xob, nws yuav tsum tau ua kom cov dej num ua haujlwm zoo li 7 hnub.
2. Lub Sij Hawm Quav Los Ntawm Biofilm
Qhov thiaj li sau qoob loo ntawm biofilm yog tsim kom muaj qee qhov me me ntawm cov tub lim dej uas tsuas yog muaj cov kev cog qoob loo uas tsuas yog suav nrog cov kev cog qoob loo zoo li qub thiab kev cog qoob loo zoo.
* Zoo li qub qoob
Qhov thiaj li hu ua cov kab lis kev cai zoo li qub yog: Txhawm rau tiv thaiv cov kab mob tshiab ntawm cov khoom noj khoom haus ntawm cov khoom noj khoom haus, kom ua tau kom muaj kev sib tiv tauj cov tshuaj tua dej, yog li muaj peev xwm ua kom nrawm nrawm ntawm cov tshuaj ntsuab sasttrates xws li ura, Therine thiab qab zib. Ua ntej, inoculate sludge (10% biochemical ntim) thiab khib nyiab dej rau hauv biochemical tank, thiab tom qab ntawd pib kev coj noj coj ua. Cov cuab yeej ntim ntawm cov muab tub lim rau hauv totchemical tank yog 35% -40}% ntawm cov tshuaj tiv thaiv tank. Cia sawv ntsug rau 4-5 h yam tsis muaj qhov ua kom cov tub lim, ces areer rau 1h, ces aອງ rau 1h, thiab rov ua haujlwm. Tom qab {4-5 hnub, saum npoo ntawm cov muab tub lim txhua tag nrho tau npog nrog biofilm. Nruam cov dej me me ntws tau pib los ntawm 6 hnub.
* Dynamic Kev Kawm
Tom qab 6 hnub ntawm kev ua kab lis kev cai, ib qho nyias nyias ntawm cov pa roj hmab uas tsis sib haum, thiab tswj cov pa roj hmab tas li, yog li nws tau hloov kho cov pa oxygen yaj cov pa). Tom qab li 15 hnub, muaj qee cov kab thiab cov kab ncig ua ke (saib nrog cov tshuaj tua hluav taws xob (thiab cov tub lim dej muaj cov nplaum thiab nplua thaum kov tau los ntawm tes. Tom qab 20 hnub, protozoa xws li flagellates, bellworms, thiab paramecium dawb tus kab mob tshwm sim. Tom qab 20 hnub ntawm kev cog qoob loo, cov metazoans xws li rotifers thiab nematodes tshwm sim, uas qhia tias biofilms tau loj hlob. Tuaj yeem pib kev lag luam kev lag luam tas mus li.
3.Qhov kev ua neej ntawm biofilm
Lub hom phiaj ntawm kev sib raug yog los xaiv cov kab mob me, tshem tawm cov kab mob uas muaj cov kab mob uas muaj cov haujlwm ntawm kev kho mob thiab phosphorus tshem tawm. Cov qauv tshwj xeeb yog los tswj kev ua haujlwm ib txwm ntawm cov txheej txheem ua ntej, thiab tom qab ntawd nruj me ntsis tswj cov txheej txheem tswj. Qhov nruab nrab ua yuav tsum tau tswj nruab nrab ntawm 2 ~ 3mm / L, thiab lub sijhawm Aeration ntawm Aerobic Tank yuav tsum tsis pub tsawg tshaj 5 teev. Thaum lub sijhawm tus txheej txheem no, ua nws txhua hnub rau kev txiav txim siab ntawm ntau qhov kev ua kom tiav, kom txog thaum lub biofilm kev ua tiav, kom txog rau thaum muaj lwm yam qhia tau raws cov cai tsim.
Cim npe nrov: Cov ntses zoo zoo ua liaj ua teb bio lim rau dej phwj mus rau dej phwj tuaj, Suav teb, chaw tsim khoom, pheej yig, hauv Tshuag, qauv dawb
