1. system were similar, at 22.04% and 22.27%, respectively. The TN removal efficiency of the 0.5-PAC/PES and 1.0-PAC/PES systems increased rapidly at 48 h. The TN removal rate of the 0.5-PAC/PES system reached 72.19%, which was nearly 50% higher than 24 h and was 2.5-2.8 times faster than PES;systems were much higher than the third-ranked 0.5-p(MMA-AAM)/PES system (62.73%)
2. %, respectively, which were mainly attributed to biodegradation. When treating SGFPW, the removal rate of TN and TOC by the 0.5-PAC/PES system was 1.5 and 1.33 times than that of the SGWN8 system, respectively. Consequently, it is feasible to use 0.5-PAC/PES monolith immobilized microorganisms for water treatment;The biomass increment of the 0.5-PAC/PES system was 18.86% higher than SGWN8 system after 96 h. Furthermore, its removal of NO 3and TN was 97.28% and 99
