CovMBBRtxheej txheem muaj qhov yooj yim rau kev khiav lag luam, thiab ntau hom pas dej ua ke siv tau yam tsis muaj kev cuam tshuam rau kev ua haujlwm ntawm cov txheej txheem; Nyob rau tib lub sijhawm, qhov sib txawv ntawm qhov chaw muab tub lim thiab qhov sib txawv ntawm qhov muab tub lim tuaj yeem xaiv tau yooj yim. Thaum qhov kev khiav dej num tiag tiag lossis dej ntim hloov pauv, tsuas yog los ntawm kev nce tus nqi ntawm cov muab tub lim, tus qauv tsim ntawm lub pas dej lom neeg muaj peev xwm tuaj yeem lav tau kom ua tiav lub hom phiaj ntawm lub cev nthuav dav, ua tiav ob qho tib si kev kho mob thiab kev nthuav dav mus ntev. qhov ntsuas kev kho mob. Tsis tas yuav tsum tau nce lub peev xwm ntawm pas dej ua ke.
Vim lub cim av nkos symbiosis system ntawm MBBR txheej txheem, activated sludge method thiab biofilm txoj kev yuav ua tau organically ua ke, thiab nws muaj qhov zoo ntawm cov av nkos membrane symbiosis technology. Cov txheej txheem activated sludge thiab cov txheej txheem biofilm yog ingeniously ua ke ua ke.
Lub hom phiaj tseem ceeb ntawm lub kaw lus yog siv cov txheej txheem biofilm nrog qhov ntsuas kub tsis zoo los txhim kho kev tshem tawm cov organic teeb meem thiab ammonia nitrogen nyob rau hauv seem aerobic, kom lawv tshem tawm tus nqi ntau tshaj qhov sib npaug ntawm cov tshuaj tov ib leeg.
Muaj cov kab mob nitrifying hauv biofilm tsim hauv MBBR tshem tawm muab tub lim. Lub exfoliation ntawm biofilm yuav inoculate cov tov tov. Piv nrog rau tib txoj kev activated sludge nyob rau hauv tib lub sijhawm nruab nrab ntawm tes nyob ntawm cov khib nyiab pov tseg hauv tib cov tshuaj sib xyaw, qhov biofilm exfoliation thiab Inoculation no yuav ua rau muaj txiaj ntsig zoo ntawm cov kab mob nitrifying hauv cov tshuaj tov. Yog li ntawd, lub xub ntiag ntawm biofilm nqa tuaj yeem pab ua kom cov nitrification ntawm ib chav tsev ntim ntawm lub pas dej, txhim khu lub peev xwm nitrification ntawm cov txheej txheem kev kho mob thib ob, thiab txhim kho kev tshem tawm ntawm ammonia nitrogen ntxiv.
