MBBR ua haujlwm teeb meem
Raws li kev paub txog kev ua haujlwm thiab kev tsim qauv tsim qauv ntawm MBBR txheej txheem, muaj ntau yam teeb meem uas yuav ntsib nyob rau hauv tag nrho cov txheej txheem MBBR, xws li clogging ntawm lub feed tube / tso tshuaj ntsuam, tsis yog-uniform mixing, clogging ntawm cov cab kuj. tsis muaj dab tsi, kev rhuav tshem cov cab kuj, cov cab kuj tsim tawm ntawm lub vijtsam tso tawm, thiab cov cab kuj dhau los ntawm lub reactor. Cov no tuaj yeem tiv thaiv tau los ntawm kev tsim qauv, raws li kev paub txog qhov project thiab kev ua haujlwm.
Nyob ntawm cov yam ntxwv ntawm cov dej khib nyiab, cov teeb meem xws li tshuaj scaling ntawm cov cab kuj tuaj yeem tshwm sim, tshwj xeeb tshaj yog rau cov dej khib nyiab uas muaj cov calcium ntau, ammonia thiab lwm yam minerals, xws li cov dej khib nyiab los ntawm kev zom zaub mov anaerobic thiab cov dej khib nyiab. Mineral nag lossis daus tuaj yeem tshwm sim thaum cov dej khib nyiab oversaturated nrog cov ion concentration. Qhov sib xyaw ntawm cov ntxhia scaling txawv thiab tej zaum yuav muaj garnet, hematite, hydroxyapatite, magnetite, thiab lwm yam. Scaling ntawm biofilm carriers cuam tshuam tsis zoo rau reactor kev ua tau zoo vim nws txo qhov zoo ntawm thaj chaw, cuam tshuam loj hloov mus, thiab yuav tsum muaj zog ntau ntxiv kom cov cab kuj raug ncua. Cov neeg nqa khoom uas teev ntau dhau los ua hnyav dua thiab nyob rau hauv qab ntawm lub reactor, yuav tsum tau hloov. pH thiab ion concentration yog lub ntsiab tseem ceeb cuam tshuam rau cov tshuaj precipitates ntawm cov cab kuj. Minerals nyiam precipitate ntau dua pH; Yog li, pH tswj tuaj yeem txo qhov fouling. Tsis pub ntxiv, txo cov pa hauv CO2stripping thiab alkalinity tshem tawm tuaj yeem pab cuam tshuam cov nqi fouling. Oxyfuel aeration yog ib qho kev xaiv kom tsis txhob ua pa tawm ntawm cov pa roj carbon dioxide kom tsis txhob pH nce. Pretreatment los ntawm tshuaj los nag lossis daus, xws li ntxiv cov txiv qaub kom tshem tawm calcium thiab magnesium, kuj yog ib qho kev xaiv.
Kev hloov pauv ntawm cov dej khib nyiab tuaj yeem ua rau muaj kev cuam tshuam, xws li kev thauj khoom organic ntxiv thaum lub sij hawm nitrification lossis ammonia oxidation, uas yuav ua rau muaj kev sib tw ntawm cov kab mob heterotrophic thiab autotrophic. Hauv qhov no, cov kab mob heterotrophic nrog kev loj hlob ntau dua tuaj yeem maj mam tswj hwm MBBR biofilm, ua rau muaj qhov tsis zoo rau kev tshem tawm ammonia.
Tsis tsim nyog biofilm shedding tshwm sim los ntawm cov tshuaj lom los yog tam sim ntawd hloov nyob rau hauv kev khiav hauj lwm tej yam kev mob (xws li sai li sai tau nyob rau hauv aeration) yuav ua rau cov txheej txheem teeb meem thiab txawm tsis ua hauj lwm nyob rau hauv huab mob, tab sis lub puab txheej ntawm biofilm yog tiv thaiv los ntawm ib txheej txheej uas ua rau lub biofilm heev. resilient rau tej kev cuam tshuam.
