upflow anaerobic sludge txaj reactor (UASB)
UASB yog ib lub zom zom kom nrawm dua, uas yog pom los ntawm cov dej hauv qab ntawm cov dej phwj mus los ntawm kev nthuav dav ntau ntau lub txaj. Tus zom zom tau muab faib ua peb cheeb tsam, namely sludge txaj, sludge txheej thiab peb-theem kev sib cais. Lub tshuab hluav taws xob cais tawm ntawm cov roj thiab tiv thaiv cov khib nyiab ntawm kev ntab thiab ntws tawm, kom MRT zoo heev piv nrog HRT, thiab qhov ua tau zoo dua rau cov methane zoo dua. Thaj chaw sludge tsuas suav rau 30% ntawm cov lej zom zom nruab nrab, tab sis 80 ~ 90% ntawm cov organic teeb meem ntawm no.
Kev sib cais peb-theem yog qhov tseem ceeb ntawm cov khoom siv UASB anaerobic digester. Nws lub luag haujlwm tseem ceeb yog roj-kua sib cais, kua-kua sib cais thiab sludge reflux, tab sis lawv txhua tus muaj cov roj foob, thaj av lim thiab thaj chaw tsis sib haum.
Cov txheej txheem zoo
Lub zom zom muaj cov qauv yooj yim thiab tsis muaj cov cuab yeej sib xyaw thiab cov muab tub lim (tshwj tsis yog peb-theem separator).
② Sau ntev SRT thiab MRT ua kom nws ncav cuag qhov siab thauj khoom.
Kev tsim cov granular sludge ua rau cov kab mob microorganism immobilized lawm thiab ua rau kev ruaj khov ntawm cov txheej txheem.
Content SS cov ntsiab lus ntawm effluent tsawg tsawg.
Cov txheej txheem ua tsis tiav
①. peb theem hluav taws xob cais yuav tsum muab ntsia.
Yuav tsum muaj cov xa dej xa tawm kom zoo rau cov xa cov dej.
Cov ntsiab lus ntawm SS yuav tsum tsawg.
Thaum lub hydraulic load siab los yog SS load siab, nws yog qhov yooj yim kom poob cov khib nyiab thiab cov kab mob me.
⑤ Muaj txuj ci siab rau kev khiav haujlwm.
