摘要：This study used a bioelectrochemical system (BES) to produce H2O2.Seven cycles after the addition of microorganisms,the BES started successfully and entered a stable operation period.During stable operation,the voltage was 581 mV,the COD removal efficiency at the anode was 85.39%,and the H 2O 2 mass concentration at the cathode was 0.5%.After the addition of 10% of graphite particles in the reaction chamber,the H2O2 production increased by 13%.After loading Pt-containing carbon black catalyst on the cathode,the H2O2 production increased by 34%.The mass concentration of H2O2 was 0.67% under the optimum process conditions of a cathode loaded with Pt-containing carbon black catalyst,pH=7,and dissolved oxygen of 8 mg/L.
