AbstractAn integration of two processes, magnetic coagulation (MC) and short-cut biological nitrogen removal (SBNR), coupled with a sequencing batch membrane bioreactor (SMBR) controlled by an automatic real-time control strategy (RTC), was developed to treat different characteristics of high strength wastewater. The treatment efficiency and microbial community-diversity of the proposed method was evaluated and investigated using swine wastewater and food waste (FW) digestate. The MC showed high removal of TSS (89.1 +/- 1.5%, 92.21 +/- 1.8%), turbidity (90.58 +/- 2.1%, 95.1 +/- 2.1%), TP (88.5 +/- 1.9%, 92.1 +/- 1.5%), phosphate (87.76 +/- 1.6%, 91.22 +/- 1.5%), and SMBR achieved stable and excellent removal of COD (96.05 +/- 0.2%, 97.39 +/- 0.2%), TN (97.30 +/- 0.3%, 97.44 +/- 0.3%) and NH4+ -N (99.07 +/- 0.2%, 98.54 +/- 0.2%) for swine wastewater and FW digestate, respectively. The effluent COD and NH4+ -N concentrations were found to meet their discharge standards. The microbial community comparison showed similar diversity and richness, and genus Diaphorobacter and Thaurea were dominant in denitritation, and Nitrosomonas was dominant in nitritation treating both swine wastewater and FW digestate.
