IC anaerobic reactor yog qhov ua tau zoo thib peb - tiam anaerobic kho tshuab. Nws cov ntsiab lus yog nyob rau hauv kev ua tiav high volumetric loading, muaj zog poob siab tsis kam, thiab ruaj khov effluent los ntawm ib tug nyob rau hauv lub cev. Nws yog dav siv nyob rau hauv kev kho mob ntawm siab -concentration organic wastewater los ntawm kev lag luam xws li npias, starch, papermaking, thiab tshuaj.
IC (Internal Circulation) anaerobic reactor yog thib peb - tiam siab -efficiency anaerobic reactor tsim los ntawm Dutch tuam txhab PAQUES nyob rau nruab nrab -1980s raws li UASB. Nws ua ke cov qauv ntawm ob lub UASBs thiab tus kheej-tsav cov txheej txheem hauv kev ncig, ua kom muaj txiaj ntsig zoo ntawm kev hloov pauv huab cua thiab cov khoom siv organic tshem tawm, thiab muaj txiaj ntsig zoo hauv kev kho dej khib nyiab.
Lub ntsiab lus tseem ceeb
Kev ua haujlwm ntawm IC ntauwd yog ua raws li "sab hauv kev ncig" mechanism: cov dej khib nyiab nkag mus rau hauv qab thiab sib tov nrog granular sludge, qhov twg nws yog degraded nyob rau hauv thawj cov tshuaj tiv thaiv chamber los tsim ib tug loj npaum li cas ntawm biogas; cov biogas nqa cov kua sib xyaw los ntawm cov riser mus rau sab saum toj roj-kua cais, qhov twg cov pa tawm thiab cov kua rov qab mus rau hauv qab los ntawm txoj kab rov qab, ua kom muaj kev sib txuas sab hauv. Cov txheej txheem no intensifies loj hloov thiab txhim kho cov tshuaj tiv thaiv efficiency.
Hauv IC reactor, tiam thiab kev sib cais ntawm biogas tshwm sim raws li hauv qab no:
Biogas tiam: Nyob rau hauv thawj thiab thib ob cov tshuaj tiv thaiv chambers ntawm lub reactor, anaerobic microorganisms decompose organic teeb meem los tsim biogas (feem ntau yog methane thiab carbon dioxide) thiab cov tshuaj tiv thaiv kua. Raws li cov biogas nce, nws nqa cov kua sib xyaw hauv thawj cov tshuaj tiv thaiv chamber mus rau cov pa roj saum toj kawg nkaus -kua cais ntawm lub reactor.
Gas-kua sib cais: Tom qab nkag mus rau hauv cov pa roj- kua cais, cov biogas, vim qhov sib txawv ntawm qhov ntom ntom ntawm cov pa thiab cov kua, txav mus rau sab saud, thaum cov tshuaj tiv thaiv cov kua dej ntws mus. Cov pa roj- cov kua cais tawm yog tsim los nrog cov pa roj hood thiab cov yeeb nkab tso tawm biogas. Cov biogas raug cais tawm thiab nkag mus rau hauv cov pa roj- cov kua cais los ntawm cov yeeb nkab sau cov pa, thiab thaum kawg tau tso tawm los ntawm cov yeeb nkab biogas sab saum toj.
Ua kua rov qab: Cov kua dej sib cais tawm hauv qab ntawm cov pa roj - kua cais thiab rov - nkag mus rau sab qis ntawm lub reactor los koom rau hauv cov txheej txheem anaerobic tom qab.
