Hluav taws xob cua sov tube biochemical kho txoj kev

Hluav taws xob cua sov tube biochemical kho txoj kev

Nws yog ib qho ntawm cov txheej txheem tseem ceeb tshaj plaws hauv cov txheej txheem dej khib nyiab organic. Hauv kev kho dej khib nyiab ntawm kev lag luam khoom noj, cov txheej txheem kev kho mob lom neeg tuaj yeem muab faib ua cov txheej txheem aerobic, txheej txheem anaerobic, stabilization cov pas dej, kev kho av, thiab ntau yam kev sib xyaw ua ke tsim los ntawm kev sib xyaw ua ke ntawm cov txheej txheem saum toj no. Cov dej khib nyiab pov tseg yog cov dej khib nyiab organic, thiab cov txheej txheem lom neeg yog cov txheej txheem kev kho mob thib ob kom txo qis COD thiab BOD5. Cov txheej txheem aerobic biological kho yog muab faib ua activated sludge txheej txheem thiab membrane raws li txoj kev loj hlob ntawm cov kab mob uas siv. Cov qub suav nrog cov txheej txheem ua kom cov sludge, theem aeration txoj kev, lom adsorption txoj kev, ua kom tiav txoj kev sib xyaw, ncua aeration txoj kev, oxidation ditch, intermittent activated sludge method (SBR), thiab lwm yam. Cov tom kawg muaj xws li biofilters, ntauwd biofilters, biological rotating discs, activated. biofilters, tshuaj lom neeg kev sib cuag oxidation txoj kev, aerobic fluidized txaj, thiab lwm yam. Feem ntau, kev kho aerobic muaj txiaj ntsig zoo rau cov dej khib nyiab tsawg. Cov txheej txheem kho anaerobic lom yog tsim rau cov khoom noj khoom haus cov dej khib nyiab, feem ntau vim tias cov dej khib nyiab muaj cov ntsiab lus siab ntawm biodegradable organic tebchaw thiab tsis muaj tshuaj lom. Tsis tas li ntawd, kev kho anaerobic muaj kev siv hluav taws xob tsawg, ua rau biogas ua lub zog, tsim cov sludge tsawg dua, thiab cov txheej txheem kho anaerobic tau kaw tag nrho, uas yog qhov tsim nyog rau kev txhim kho ib puag ncig kev nyiam huv. Nws tuaj yeem ua haujlwm raws caij nyoog lossis ncua sijhawm, thiab cov sludge tuaj yeem khaws cia rau lub sijhawm ntev.
