Lub ntsiab
MBBR (Tsiv Phaj Biofilm Reactor) yog cov dej photical txuag tau zoo heev. Nws siv cov kev ywj pheej tsiv tawm media li cov neeg nqa khoom rau cov microbial. Cov xov xwm no feem ntau yog ua los ntawm kev txhim kho corrosion - resistant cov ntaub ntawv xws li high - ntom polyethylene (HDPE), uas tuaj yeem nqa biofilms thiab kho cov kuab paug hauv dej. Tab sis li cas ua tau cov xov xwm no ua haujlwm, thiab nyob rau hauv daim teb twg uas lawv siv tau? Niaj hnub no, peb nrhiav cov lus teb rau cov lus nug no.
Dab tsi yog cov ntsiab cai ua haujlwm ntawm MBRB media?
(1) Microbial Connectment:Saum npoo ntawmMBRB MBRyog feem ntau ntxhib thiab ntxig. Thaum cov dej phwj tuaj los ntawm, cov kab mob me me xws li cov kab mob thiab fungi tuaj yeem txuas rau saum npoo ntawm cov xov xwm, sib sau biofilms.
(2) Kev qias neeg tsis zoo:Tom qab cov ntaub ntawv biofilm ntawm nws cov npoo av, cov kab mob me tsis dhau ntawm cov neeg muaj kuab paug, xws li cov organic (cod / bod) thiab ammonia nitrogen (NH₃ - N) n).
(3) ib txhij nitrification thiab denitricification:Nyob rau hauv ib puag ncig uas muaj micro - aerobic thiab anaerobic zones nyob sab hauv tshaj tawm (nh₃ → tsis muaj nitrogen los ntawm cov dej phwj tuaj.
2. Kev txav zuj zus ntawm kev tshaj xov xwm
(1) Aeration - Dr.Thaum lub sijhawm ua haujlwm, hauv qab qhov chaw ntawm kev kho mob tank txhaj tshuaj ntau ntau rau hauv cov dej phwj. Qhov no ua rau bioflms rau ntawm MBRB media kom nkag tau tag nrho nrog cov dej phwj tuaj.
(2) Anti - Clogging Mechanism:Lub pob metight yuav raug tshem tawm thiab txav mus los dawb nrog cov dej los ntawm me ntsis co hauv biochemical tank. Clogging tsis tshua muaj tshwm sim.
(3) Biofilm Rov Ntxiv:Thaum biofilm ntawm cov xov xwm nce mus txog qhov tuab tuab, nws yuav tog rau hauv qab ntawm lub pas dej. Lub siab cuam tshuam rau hauv qab ntawm ib cheeb tsam Aerer tuaj yeem ntxuav kom sai li sai tau cov seem ntawm cov xov xwm, cia nws nce rov qab mus rau thaj tsam aeration.
Cov ntawv thov tseem ceeb ntawm MBRB media
MBRB med yog siv nyob rau hauv kev kho dej huv, tshwj xeeb yog rau kev tshem tawm cov organic (bod / cod) thiab nitrogen sib xyaw xws li ammonia. Lawv feem ntau yog siv hauv kev lim dej hauv lub nroog, kev lag luam xws li khoom noj thiab dej haus, kev tsim khoom, thiab txawm tias cov tshuab pov tseg tsis zoo. Cov ntsiab lus yog raws li hauv qab no:
Dej phwj yog lub neeg khib nyiab tsim los ntawm cov neeg lub neej txhua hnub, feem ntau yog los ntawm chav ua noj, chav dej, thiab khaub hlab. Nws muaj ntau cov tshuaj organic, nrog rau cov as-hamients xws li nitrogen thiab phosphorus. Lub biofilm nyob rau saum npoo ntawm MBRB media muaj ntau cov kab mob me, suav nrog cov kab mob, fungi, thiab protozoa. Cov kab mob no decompose cov pa paug nyob hauv cov metabolism hauv tsev los ntawm cov metabolism hauv tsev, txo nws cov tshuaj oxygen xav tau (COD). Nws thiaj li, cov neeg kho dej khib nyiab raug rho tawm mus rau hauv cov dej hauv nroog thiab tuaj yeem siv rau cov qoob loo irrigating thiab tswj hwm lub neej dej.
Lub tshuab MBBR MBBR tuaj yeem tshem cov nitrogen los ntawm cov dej khib nyiab. Thaum nyob rau hauv kev siv, ib qho kev tsim nyog micro - ib puag ncig yog tsim nyob rau hauv tus reactor, suav nrog kev tswj kev mob xws li yaj oxygen thiab pH nqi. Nitrifify cov kab mob thiab kho tus kab mob tuaj yeem ua kom tiav thiab loj hlob ntawm biofilm ntawm MBBR me me. Tus qub oxidizes ammonia nitrogen rau nitrite thiab tom qab ntawd txuas ntxiv mus rau nitrate. Cov kab mob tom ntej nitrate rau cov pa roj nitrogen nyob rau hauv anoxic tej yam kev mob thiab tso nws mus rau hauv cov huab cua. Thaum kawg, cov ammonia cov ntsiab lus nitrogen nyob rau hauv cov neeg khib nyiab yog txo qis.
Cov xov xwm no tseem tsim nyog rau kev kho cov dej khib nyiab los ntawm kev ua zaub mov, tshuaj lom neeg, pulp thiab cov ntawv mills. Piv txwv li, zaub mov noj kom muaj dej khib nyiab muaj cov tshuaj organic ntau xws li cov lactose, protein, thiab rog, nrog ib tug heev cod conferration. Cov kab mob me me ntawm MBRB media tuaj yeem hloov kho kom haum rau cov qauv hluav taws xob hauv dej, thiab yuav siv cov qauv organic hauv dej, thiab yuav siv cov qauv tshuaj organic, thiab yuav tsum tau siv cov qauv tshuaj organic, thiab yuav siv cov khoom siv ntsuab thiab dej hauv thaj chaw Hoobkas.
Nyob rau hauv thaj teb ntawm Aquaculture, MBRBult Technulture, lub tshuab txiav MBBR yog siv los tswj cov dej zoo thiab tiv thaiv kab mob. Txwv tsis pub, nrog kev nce hauv aquaculture ceev, cov dej ntas nyob hauv ntses pas dej yuav ua rau Eutrophic, ua rau cov ntses ntses lossis tuag. MBRB med tuaj yeem txuas nrog cov ntses - pas dej dej ncig ua si. Los ntawm kev Aeration, cov dej ntas dej ntws hauv cov reactor, uas tuaj yeem nce cov pa oxygen hauv cov dej thiab decompose qee cov ammonia nitrogen thiab nitrite hauv dej.
Txhim kho koj txoj haujlwm kev kho dej nrog MBRB media
Hauv tsab xov xwm no, peb tau tshawb txog cov qauv kev ua haujlwm ntawm kev kho dej haus dej thiab kawm txog lawv cov ntawv siv dej loj, suav nrog kev kho dej nyab xeeb, thiab aquaculture.
AQUEsust yog dej - Kev Kho Mob Khoom Siv thiab Chaw Tsim Tshuaj Hauv Suav. Peb tuaj yeem muab cov dej ntau ntau - Cov khoom siv kho mob thiab khoom siv ntxiv raws li cov kev xav tau ntawm koj cov dej - kev kho mob. Yog tias koj xav kawm cov ntaub ntawv cuam tshuam lossis tau txais kev cai MBRR media, nyem "no"Hu rau peb cov kws paub.
