Dab tsi yog activated sludge?
Nws yog cov sludge uas muaj qee yam tseem ceeb thiab cov dej phwj huv huv uas muaj cov kab mob micelles, protozoa, metazoans thiab lwm pawg microbial thiab organic thiab inorganic tshuaj nyob rau hauv cov dej phwj tuaj adsorbed.
Cov txheej txheem ntawm activated sludge degrading organic teeb meem hauv dej phwj tuaj
Cov kab mob microbial uas koom nrog hauv kev kho cov dej phwj tuaj sludge feem ntau yog cov kab mob aerobic.
Aerobic Granular Sludge (AGS) yog granular activated sludge tsim los ntawm microbial self-agglomeration.
Piv nrog rau cov activated sludge tsis tu ncua, nws tsis tshua muaj sludge bulking, muaj zog cuam tshuam tsis kam, tuaj yeem tiv taus cov organic load siab, thiab sib xyaw cov kab mob ntawm cov khoom sib txawv.
Aerobic granular sludge muaj cov qauv ntom ntom thiab loj particle loj. Vim muaj kev txwv ntawm kev hloov pauv ntawm cov pa oxygen, cov granular sludge nthuav tawm thaj chaw aerobic sab nraud thiab anoxic lossis anaerobic cheeb tsam sab hauv, uas yog aerobic, facultative thiab anaerobic. Cov kab mob anaerobic muab lawv tus kheej tsim nyog nyob ib puag ncig, yog li ua rau aerobic granular sludge ua ntau yam aerobic thiab anaerobic metabolic kev ua ub no.
Piv nrog rau cov tsoos activated sludge flocs, aerobic granular sludge muaj qhov zoo hauv qab no: cov duab tsis tu ncua, compact thiab compact qauv, zoo settling kev ua tau zoo, siab biomass, thiab tib lub sij hawm, nws muaj ntau yam microbial zog, thiab cov nyiaj ntau tshaj sludge. yog me me. Nws tau dhau los ua ib qho kev cog lus zoo tshaj plaws hauv kev kho dej khib nyiab pov tseg vim nws ua siab ntev rau cov co toxins thiab cov organic load hloov pauv.
