[Study on running efficiency of more spots divisional influent of anaerobic baffled reactor]

The experimentation studied running efficiency of divisional influent mode to anaerobic baffled reactor (ABR) compared with single influent anaerobic baffled reactor that had four compartments. The results showed that the average soluble COD removal rate of single influent was 30%, but divisional influent anaerobic baffled reactor was 35%, and the highest value might reach to 45%, the removal rate of COD was improved over 5% than single influent anaerobic baffled reactor. The main biological processes were micro-aerobic hydrolysis and acidification, at the same time the methane-producing bacteria existed too. The means of divisional influent could avoid high organic loading in the first compartment that led the volatile fatty acids (VFA) to accumulate overly and might improve the fact of lacking organic substance at the back compartment and let reactor to have high microorganism activity and improve ability of reducing contamination.
