Studies on the effects of different bio-media on bio-contact oxidation reactor

摘要

Bio-media was one of the major factors that affect the performance of bio-contact oxidation. Two kinds of Bio-medias were compared from the effects of different bio-media on bio-contact oxidation reactor. The results showed that, the dosage impact on web-like filler was bigger than combined filler, for web-like filler, when the dosage rate was optimum, the oxygen transfer rate increased with the dosage rate increasing, the value of KLa(20℃) increased 90 percents compared with black test at the most; the filming speed of combined filler is more quickly than web-like filler; the ability of loading shock of combined filler reactor is better than web-like filler reactor, the major reason is that the quantity of the membrane is different in reactor.
