Study on the effect of hydrolysis acidification for divisional influent ABR

The experimentation adopted anaerobic baffled reactor (ABR) which has four compartments, and the reactor with influent ratio of 4:3:2:1. The effect of hydrolysis acidification was studied by divisional influent that compared with the single influent of the anaerobic baffled reactor. The results show that the effluent of divisional influent were more formic acid and acetic acid than single influent, and the divisional influent may improve the COD removal efficiency and increase the ability of hydrolysis acidification of ABR.
