An AOPs of Fe/C micro-electrolysis (FCME) and Fenton oxidation (FO) was combined with anaerobic granular sludge (AGS) to treat recalcitrant pharmaceutical wastewater in this study. The AOPs showed significant COD reduction during both FCME and FO. For influent COD=9000∼11000mg/L, the pretreatment effluent COD could reach below 5500mg/L under 0.6% H2O2 adding condition. And the B/C of pharmaceutical wastewater was improved from 0.11 to 0.37. The subsequent AGS treatment in EGSB got a COD removal rate of 87.1%. The extracellular polymeric substance (EPS) and mean diameter detection demonstrated high stability of EGSB. AOPs with AGS is supposed to be a better option for recalcitrant wastewater treatment process.
