Anaerobic biological treatment of sulphate - laden wastewater has been proven to be a feasible approach. However, it encounters formidable challenges when applied under nutrient poor conditions. The efficacy suspended fillers in augmenting microbial concentrations and enhancing the removal contaminants had empirically validated. there is limited research on enhancement by fillers, mechanism remains unclear. Thus, fill anaerobic bioreactor systems were established investigate its feasibility nutrient-poor conditions, mechanisms further explored. findings demonstrated that presence enabled achieve efficiency approximately 68.9%, even organic load rate was as low 0.08 gCOD·(L·d)-1. Principal Coordinates Analysis results clearly differences community composition between sludge filler samples at each stage (R > 0, P < 0.05). Further analysis revealed Desulfobulbus Desulfobacter, which closely associated with removal, exhibited higher relative abundances compared samples. Furthermore, functional genes found exhibit more pronounced expression sample fillers. These suggested creates favourable environment for certain microorganisms, particularly some sulphate-reducing bacteria, activity increasing efficiency.
