The treatment of pharmaceutical effluent using an appropriate technology has become so important. Anaerobic packed bed reactor is an efficient method for pharmaceutical effluent treatment because of the high organic content present in it. In this study, a heavy-polluted pharma effluent is treated using an anaerobic packed bed reactor. The performance of the anaerobic reactor was identified with respect to chemical oxygen demand (COD) removal, methane yield, and gas production. The results showed that COD was reduced from 73% to 60% for an organic loading rate (OLR) of 0.6036-1.7487 kg COD m·d. As the OLR increases, the removal efficiency of COD decreases gradually to around 52% for an OLR of 2.34 kg COD m·d.
使用适当的技术处理制药废水变得非常重要。由于其中含有高浓度的有机物，厌氧填充床反应器是处理制药废水的有效方法。本研究采用厌氧填充床反应器处理高浓度制药废水。考察了化学需氧量（COD）去除率、甲烷产量和产气量等方面来评估厌氧反应器的性能。结果表明，在有机负荷率（OLR）为 0.6036-1.7487 kg COD m·d 时，COD 去除率从 73%降低至 60%。随着 OLR 的增加，COD 的去除效率逐渐降低，当 OLR 为 2.34 kg COD m·d 时，COD 的去除效率约为 52%。
