Shale gas flowback and produced water (SGFPW) pose significant challenges to biotechnology due their high salinity. In this study, we explored a novel method utilizing an amphiphilic copolymer of methyl methacrylate acrylamide (p(MMA-AAM)) powdered activated carbon (PAC) modify poly(ether sulfone) (PES). We prepared series monoliths for microorganism immobilization using both thermal-induced phase separation non-solvent-induced separation. Characterization the via FTIR, SEM, BET analysis revealed improved hydrophilicity in p(MMA-AAM)-modified increased specific surface area (SSA) with PAC addition. Particularly, highest SSA was observed 0.5 g (0.5-PAC/PES) monolith at 235.1861 m2/g. Wastewater treatment experiments demonstrated that 0.5-PAC/PES system exhibited superior pollutant removal performance. It enhanced microbial efficiency promoted growth, thereby boosting biological efficacy efficiency. The achieved nearly 100% NO3- total nitrogen (TN) simulated SGFPW. Besides, rates TN organic (TOC) actual SGFPW by were 1.5 times 1.3 higher, respectively, than those suspended microorganisms. This work introduces new approach immobilize microorganisms, enhancing activity under salinity conditions.
