Qhov zoo thiab qhov tsis zoo ntawm MBBR biological media

Cov tsos mob thiab cov qauv ntawm cov khoom siv roj ntsha sim zam lossis tiv thaiv cov roj tsis ua haujlwm luv luv hauv cov khoom siv deodorization, thiab qhov ntim ntawm cov khoom siv roj ntsha tuaj yeem muab qhov chaw sib cuag txaus thiab lub sijhawm sib cuag txaus rau kev ua haujlwm zoo. Nws tseem yog nruab nrog cov as-ham tsim nyog thiab buffers kom ua tiav cov txiaj ntsig xav tau, thiab tsis tas yuav ntxiv cov kab lis kev cai nruab nrab thaum lub sijhawm thov. Cov khoom filling muaj qhov ntsuas thiab muaj peev xwm los kho tus nqi pH yam tsis ntxiv cov kua qaub thiab alkali. MBBR muab tub lim ua tshuab yog thawj zaug siv txawv teb chaws, tab sis feem ntau nws yog ib qhov me me thiab nruab nrab-qhov loj qhov kev kho dej khib nyiab. Ob peb 50,000- tuj dej ua haujlwm siv MBBR ua tshuab. Txawm li cas los xij, nrog kev txhim kho cov kev cai ntawm cov dej khib nyiab hauv kuv lub teb chaws nyob rau xyoo tas los no, MBBR kev siv tshuab siv hauv cov dej phwj tuaj. Kev siv cov chaw ua haujlwm hloov khoom dua tshiab tau dhau los ua ntau dua, thiab ntau cov duab ntawm cov khoom siv feem ntau siv. Los ntawm plaub lub xyoos dhau los, qhov zoo ntawm cylindrical fillers yog pom tseeb dua, thiab cov tub ntxhais siv tshuab yog qhov zoo tshaj plaws. Cov txheej txheem MBBR tsis tsuas yog muaj cov txheej txheem lom neeg ntawm kev cuam tshuam, tab sis kuj muaj cov av nkos ntev. Qhov zoo thiab qhov tsis zoo ntawm kev tawm ntawm cov sludge tsawg, thiab qhov tseeb thiab kev sib koom ua haujlwm muaj peev xwm ntawm cov txheej txheem activated sludge. Piv nrog rau lwm yam kev siv thev naus laus zis, MBBR ua tshuab muaj qhov zoo thiab qhov tsis zoo hauv qab no: Cov khoom sib xyaw ua ke feem ntau siv rau cov kab mob hu rau huab cua Cov zaj duab xis dai rau hauv lub tank oxidation thiab aeration tank. Yog tias muaj qee qhov seem hauv dej, nws yuav ua rau muaj kev phom sij ntau dua rau kev pabcuam lub neej yog tias muaj cov seem seem tsawg dua hauv cov dej, thiab qhov tawg ntawm huab cua oxidation kuj muaj teeb meem heev. Kev teeb tsa biomass composite muab tso rau hauv lub tank aerobic ntawm kev kho dej khib nyiab tuaj yeem ua rau kom biomass thiab tau txais txiaj ntsig zoo COD tshem tawm.
1. Cov nyhuv denitrification tau zoo Cov kab mob ntawm lub plasmid carrier muaj lub hnub nyoog sludge ntev thiab txoj kev loj hlob ntawm adhesion yog yooj yim rau kev loj hlob ntawm cov kab mob nitrifying. Lub concentration ntawm nitrifying kab mob yog siab, yog li lub peev xwm nitrification thiab denitrification yog pom tseeb.
2. Muaj zog carburizing muaj peev xwm thiab siab-concentration flora yuav muaj ib tug ntev COD dissolving muaj peev xwm, thiab COD muaj peev xwm load yuav siab heev. Tsis tas li ntawd, cov tsiaj muaj nplua nuj nyob hauv plasmid cab kuj nce lub peev xwm los kho nyuaj Solubility ntawm yaj cov organic tebchaw.
3. Muaj peev xwm tiv taus kev cuam tshuam kev thauj khoom. Cov yam ntxwv ntawm high-concentration biomass thiab nws adhesion thiab kev loj hlob ua rau cov tshuaj tiv thaiv pas dej ua ke muaj cov concentration ntawm cov kab mob siab, uas tuaj yeem tiv taus qhov kev hloov pauv ntawm cov dej nkag, dej ntws, thiab qhov kub thiab txias, ua kom cov dej tso tawm ruaj khov.
4. Kev poob dej me me Tom qab kev tsim qauv nruj, cov txheej txheem MBBR ntawm kev tsim kho vaj tsev yuav tsis raug txhaws, thiab tsis tas yuav tsum tau tu kom tas mus li.
5. Cov hneev taw me me nyob rau hauv cov xwm txheej ntawm kev ua tiav tib lub peev xwm thiab ua tiav cov txiaj ntsig, kev noj cov tshuaj lom neeg lom neeg tuaj yeem txo lub peev xwm thiab kev ua haujlwm hauv av, thiab kev ua haujlwm hauv av tuaj yeem txuag tau li 80 feem pua ​​​​piv nrog cov txheej txheem activated sludge.
6. Tsawg sludge ntau lawm Cov roj ntsha sludge ntawm cov khoom siv roj ntsha floating muaj lub hnub nyoog sludge ntev, thiab cov theem lom neeg muaj ntau thiab ruaj khov. Tsis tas li ntawd, cov kab mob microbial nws tus kheej yog oxidized thiab decomposed, yog li lub kaw lus tsim cov sludge tsawg thiab kuj txo cov nqi dej khib nyiab.
7. Kev siv hluav taws xob qis dua Qhov kev faib ua feem ntawm kem-hom floating biological muab tub lim yog tswj tau zoo, thiab qis qis txo qis kev siv hluav taws xob thiab txhawb kev hloov pauv cua sov. Cov tshuaj tua kab mob hauv cov tshuaj tua kab mob tuaj yeem tig tau yooj yim thiab du hauv dej, txhim kho kev sib tsoo thiab laser txiav ntawm cov pa npuas me me hauv dej, ua kom lub sijhawm tos ntawm cov npuas me me hauv dej, thiab ua kom cov pa oxygen siv tau los ntawm {{2 }} hli, uas tsim nyog txo cov khoom siv hluav taws xob.
8. Txoj kev tswj kev ua haujlwm yooj yim tau hais txog cov txheej txheem tsim qauv nruj. Txoj kev ua haujlwm ntawm MBBR txheej txheem ntawm kev tsim kho vaj tsev yog qhov zoo ib yam li cov txheej txheem activated sludge, tab sis cov sludge bulking ntawm cov txheej txheem activated sludge tsis tuaj yeem pom, Sludge nce thiab sludge outflow thiab lwm yam teeb meem, yog li nws tsis yog. tsim nyog los saib xyuas cov xwm txheej sludge ntawm lub pas dej ua ke thiab hloov cov kev ua haujlwm tsis tu ncua, kom txoj kev tswj xyuas kev ua haujlwm txhua hnub yog qhov yooj yim dua.
9. Kev tu thiab kho tsawg dua Lub columnar floating biological muab tub lim nrog cov khoom siv ruaj khov (tsis yog ua los ntawm cov khoom siv raw khoom) tuaj yeem ua kom ntseeg tau tias tsis tas yuav hloov nws li 20 xyoo. Kev siv lub sij hawm ntev ntawm cov roj tawg uas siv rau hauv cov chaw txhawb nqa yuav tsum muaj kev saib xyuas, uas txo cov nqi tu ib txwm thiab ua kom lub sijhawm ua haujlwm tsis tu ncua ntawm qhov system. Daim ntawv thov teb: Nws yog qhov tsim nyog rau kev kho dej haus thiab dej phwj tuaj, thiab cov nyhuv tiag tiag yog qhov zoo heev. Nws kuj tseem siv tau rau cov pas dej anaerobic, cov pas dej aeration, thiab cov txaj dej lom neeg ntawm cov khoom siv kho dej khib nyiab. Tus nqi yog siab dua, thiab tus nqi kev ua tau zoo yog siab dua.
