文摘

Biogas scrubbing enhanced TN and P-PO43− recovery via biomass assimilation. Nitrification was limited by IC in the absence of biogas supply. Biogas scrubbing maintained pH below inhibitory levels during the light period. Biogas upgrading supported an efficient nitrification-denitrification process. Biomass recycling resulted in unialgal cultures with high settling rates.
