Abstract :
Filled the divisional influent anaerobic baffled reactor (DIABR) with stuffing and the activated sludge of the secondary settling tank was inoculated for attaching bio-film to train anaerobic microorganism. The wastwater inpoured the reactor with ratio of 4:3:2:1 in the four compartments, the experiment compared with the single influent anaerobic baffled reactor (SIABR). The two reactors ran under the conditions of HRT=8 h and ORL=0.8 kgCOD/m3ldrd for 15 days. Then the running parameter was modulated with HRT of 4h. The removal efficiency of COD in the DIABR was higher than the single influent under the same conditions after 23 days,the average removal rate of COD was 35% when reactor ran for 60 days. Under the same conditions, start-up on DIABR has been successful. Through the examination studied showed that the DIABR had stronger adapted to the different conditions of influent manner and waterpower load and organic load. So through properly changing the running manner of ABR could be improved water quality of effluent.
