AO——MBBR Process for Treatment of Low--concentration Municipal Sewage
Abstract AO—MBBR process was used to treat lOW—concentration and lOW CN municipal sew—
ageThe influence of carrier dosing point and temperature on nitrification and denitrification was investi—
gatedUnder normal water temperaturesthe average removal rates of anunotlia nitrogen by dosing cam—
ers at the front-end and back—end of the aerobic tank were 957and 926respectivelyThe C01Te·
sponding average removal rates of TN were 224and 91respectivelyThese results were obtained
when the hydraulic retention time in the biochemical system was 1 2 hreflux ratio was 300DO in aer—
obic tank was 27 to 70 mgLand dosage of K3 suspended biological carrier was 1 1of aerobic tank
volumeThe resistance to ammonia nitrogen shock loading by dosing carriers at the front—end was higher
than at the back—end of the aerobic tankUnder low temperatures of 63 to 1 05森the system still
maintained a high ammonia nitrogen removal rateThe average removal rate of ammonia nitrogen by do—
sing carriers at the front—end of the aerobic tank was 829which was 8higher than at the back—end
