In this study, impact of a rice straw-derived biochar on the anaerobic digestion of piggery wastewater was investigated under different ammonium "stress levels". The results showed that the biogas yield was decreased from 1293.27mL to 402.31 mL and the COD removal rate was decreased from 70.68% to 38.13% with the NH4+-N concentration increasing from 900mg/L to 3500 mg/L. At no ammonium "stress level", the COD removal rate was increased from 70.68% to 83.75%, and biogas yield was increased from 1293.27mL to 2306mL with the increase of biochar dosage from 0g to 15g. While with the addition of bi...
