摘要: In this study, pharmaceutical wastewater with high total dissolved solids (TDSs) and chemical oxygen demand (COD) content was treated through a sequential anaerobic–aerobic treatment process. For the anaerobic process, an up-flow anaerobic sludge blanket (UASB) was applied, and a COD removal efficiency of 41.3±2.2% was achieved with an organic loading rate of 8.11±0.31 g COD/L/d and a hydraulic retention time of 48 h. To evaluate the salinity effect on the anaerobic process, salts in the wastewater were removed …
