%X Experiments on organic acids conversion in methanogenic phase of the two phase anaerobic process were conducted. The results showed that when the acidogenic phase was in mixed acids fermentation and its load was 41.5 kg/(m3·d), the load of methanogenic phase was 6.05 kg/(m3·d), the substrate conversion velocity of bacteria inhabited at the same height of UASB reactor as follows: acetic acid>ethanol>butyric acid>propionic acid; ethanol utilized microbial had the same pH range as methanogenic bacteria; ethanol type fermentation was the optimal acidogenci type fermentation for the two phase anaerobic process; the conversion of acetic acid was rather high, but the others organic acids will be convert to acetic acid make it the rate limiting step for anaerobic degradation.
