Piv nrog rau cov txheej txheem sludge thiab hom tsau-xyaw biofilm txoj kev, MBBR tsis tsuas yog muaj qhov ua tau zoo thiab kev ua haujlwm yooj yim ntawm cov txheej txheem sludge, tab sis kuj muaj cov yam ntxwv ntawm kev cuam tshuam kev thauj khoom, ntev sludge hnub nyoog thiab tsawg dua sludge hauv tsoos. biofilm txujci.
(1) Cov yam ntxwv ntim
Cov tub lim ua feem ntau ua los ntawm polyethylene, polypropylene thiab lawv cov ntaub ntawv hloov kho, polyurethane ua npuas, thiab lwm yam. Lub zog nqus tau ze rau ntawm cov dej, feem ntau yog cylindrical thiab kheej kheej, uas yooj yim rau dai ntawm zaj duab xis, tsis muaj agglomeration, tsis muaj blockage, thiab yooj yim tev tawm.
(2) Muaj peev xwm ua kom zoo txaus ntseeg
Cov khoom noj muaj txiaj ntsig zoo, anoxic thiab anaerobic ib puag ncig yog tsim nyob rau pob, thiab nitrification thiab denitrification tshua tuaj yeem tshwm sim hauv ib qho reactor, uas muaj cov txiaj ntsig zoo ntawm kev tshem tawm ammonia nitrogen.
(3) Muaj txiaj ntsig zoo ntawm kev tshem tawm cov organic
Qhov sludge concentration hauv cov tshuaj tiv thaiv yog qhov siab, thiab qhov dav dav sludge concentration yog 5-10 zaug ntawm cov txheej txheem sib xyaw sludge, uas tuaj yeem siab li 30-40g / L. Txhim kho txoj kev ua haujlwm ntawm cov organic, thiab muaj zog cuam tshuam thauj khoom tsis kam.
(4) Yooj yim rau kev tswj hwm thiab kev tswj hwm
Tsis tas yuav txhim kho qhov muab kauv ntsaws rau hauv qhov chaw aeration tank, uas yooj yim saib xyuas txij nkawm ntawm qhov muab tub lim thiab cov khoom aeration hauv qab ntawm lub tank, thaum txuag kev nqis peev thiab hauv pem teb.
