In this study, anaerobic biodegradability of high strength pharmaceutical wastewater from six main departments in a pharmaceutical manufacturer was firstly evaluated by a series of batch experiments. Based on the experimental data, two stage-UASBs were applied to treat the wastewater containing effluent from all manufacturing departments. The influence of organic loading rate (OLR) from initial 1.0 g COD/(L·d) to maximum 12.0 g COD/(L·d) on the performance of reactor was investigated through step-decreasing HRT. Influent COD was diluted to 10 000 mg/L with the adjustment of pH to 6.8~7.1. Total COD removal efficiency of 73.5% with the effluent COD of 2 600 mg/L was noticed at OLR of 6.0 g COD/(L·d) (maximum OLR for practical engineering application). Satisfactory organic compound removal efficiency during the long term run indicted the feasibility of two-stage UASBs for treatment of this kind of pharmaceutical wastewater effluent.
