| Abstract |
This study was conducted to characterize the microbial growths on media in aerobic and anaerobic fixed-film processes upon the variation of organic loading rates. It appears that the growth on media became more likely to be suspended rather than attached as organic loading rate reached around 3 ㎏ COD/㎥/d. At an organic loading rate less than around l㎏ COD/㎥ /d the microbial attachment became stronger in aerobic than in anaerobic condition. As the organic loading rate increased, the effluent quality became poorer. However, at the same loading rate, the effluent concentration varied little, even influent concentration greatly increased. The maximum F/Mv (㎏ COD)/㎏ MLVS/d)ratio measured from anaerobic condition was about 1 which is lower than that of activated sludge process. The computed minimum SRTs were respectively 7.6 days for anaerobic and l.ldays for aerobic condition. |
