Kev kho dej khib nyiab anaerobic ua haujlwm li cas?
Kev kho dej khib nyiab anaerobic yog kev kho cov organic uas siv cov kab mob anaerobic los decompose thiab tshem tawm cov pa phem hauv cov dej khib nyiab. Txawm hais tias cov qauv kev kho anaerobic tuaj yeem siv ntau hom, lawv feem ntau muaj qee cov duab ntawm bioreactor lossis cia khoom uas tuaj yeem ua kom tsis muaj pa oxygen nyob ib puag ncig xav coj cov txheej txheem anaerobic digestion.
Cov txheej txheem kho cov dej khib nyiab anaerobic muaj ob theem: theem acidification thiab methane manufacturing theem, txhua yam nyob rau hauv ib tug dynamic equilibrium xeev. Nyob rau hauv lub preliminary acid tsim theem, anaerobic microorganism decompose nyuaj natural compounds rau hauv tsawg nyuaj short-chain txaus ntshai tej yam ntuj tso acids. 2d theem, lub npe hu ua methane manufacturing theem, muaj ob kauj ruam: acetic acid ntau lawm, anaerobic microorganism synthesize ntuj acids kom zoo li acetate, hydrogen thiab carbon dioxide; thiab methane ntau lawm, thiab tom qab ntawd cov kab mob anaerobic ua rau cov qauv tshiab tshiab, tsim cov roj methane thiab carbon dioxide. Cov khoom siv los ntawm cov khoom siv no tuaj yeem siv los ua cov roj, thiab cov dej khib nyiab tuaj yeem siv los kho ntxiv thiab / lossis tso tawm.
Raws li cov khoom siv hluav taws xob tshwj xeeb thiab cov tseev kom muaj, cov qauv kev zom zaub mov anaerobic tuaj yeem tsim los ua ib-theem lossis ntau theem, uas muaj peev xwm lawv tuaj yeem tsim nrog cais cov kua qaub tso dej thiab cov khoom siv bioreactor.
