Abstract

Abstract

As an advanced treatment process, biological activated carbon process can effectively remove organic pollutants from wastewater. In order to investigate the advanced treatment effect of biological activated carbon process on pharmaceutical wastewater, the effect of high-efficiency composite bacteria on wastewater treatment performance of biological activated carbon process was studied, and the influence of the operating parameters was discussed. The results showed that addition of composite bacteria could significantly improve pollutant removal effect. The high-efficiency degradation bacteria coupled with biological activated carbon process had an average removal rate of 38.2% for COD, 77.8% for ammonia nitrogen, and 84.3% for AOX under conditions of packing filling degree of 80% and hydraulic retention time of 10 h. The effluent was superior to the third-level limit value of China's Integrated Wastewater Discharge Standard (GB 8979-1996)。
