Abstract


In order to enhance the degradation of Di-n-octyl phthalate (DOP).One bacterial strain was inoculated in SBR. Bioaugmentation by inoculating DOP-degrading bacteria effectively shortened the start-up of SBRs and significantly enhanced DOP degradation in bioreactors (p<0.05), 92.3% DOP removal rate was achieved in consortium bioaugmented SBR, which was double of control SBR. The DOP removal in control reactor was only 37%. The results from this study
suggest bioaugmentation is an effective and feasible approach for DOP waste water treatment in practical engineering.
