Study on enhancement of granulation and microbial community of floc sludge by electrolytic iron-carbon filler
Utilizing an external power sequenced batch reactor (SBR) at a high aspect ratio (RH/D) of 7.5 and incorporating activated sludge and iron-carbon fillers (at 0.6 kg), synthetic wastewater served as the influent. The research examined sludge morphology, pollutant removal performance, microbial community shifts, and coupled process mechanisms during operation
