In order to explore the feasibility of simultaneous CO2 sequestration and N/P nutrients recovery in sludge anaerobic digestion coupled with mineral carbonation, different ratios of Mg2+/Ca2+ were added in the anaerobic digestion systems with sludge hydrolysate as substrate, to investigate the performance of simultaneous CO2 sequestration and nutrients removal. The results showed that the addition of Mg2+/Ca2+ of (20mmol/L)/(0mmol/L), (10mmol/L)/(10mmol/L) and (0mmol/L)/(20mmol/L) could promote the degradation of organic matters, so that the biogas production increased by 16.97%, 21.56% and 23.99%, and the CO2 content was reduced from 27.27% to 24.81%, 22.06% and 21.98%, respectively. The phosphate concentration was reduced by 63.46%~66.47% with Mg2+/Ca2+ addition of different ratios. However, ammonia nitrogen concentration was reduced only in the digesters with Mg2+/Ca2+ added at (20mmol/L)/(0mmol/L) and (10mmol/L)/(10mmol/L). XRD analysis revealed that struvite and magnesium carbonate, struvite and calcite, calcite and monetite were respectively formed in the digesters with Mg2+/Ca2+ added at (20mmol/L)/(0mmol/L), (10mmol/L)/(10mmol/L) and (0mmol/L)/(20mmol/L). The combined addition of Mg2+/Ca2+ in equimolar amount achieved the best simultaneous CO2 sequestration and N/P nutrients recovery.
