In electrocatalytic anaerobic digestion, the methane content in biogas can be enhanced. With acetic acid as the substrate, this study investigated the kinetics of biogas production and substrate degradation in an electrocatalytic anaerobic digestion system. Experimental results showed that with the addition of different initial acetic acid concentrations (8.3, 10.0, 11.7 g/L), the methane content in biogas increased with increasing acetic acid concentration. When the acetic acid concentration was 11.7 g/L, the average methane content reached 80.6% in batch experiments. Based on the carbon balance relationship in the electrocatalytic anaerobic digestion process, kinetic studies were conducted using both the first-order kinetic model and the Gompertz model. The study revealed that acetic acid conversion efficiencies at the three concentrations were 85.6%, 97.2%, and 97.4%, with biomass growth accounting for 22.1%, 29.9%, and 28.5% of the carbon distribution, respectively. The correlation coefficients (R2) for both models in fitting the biogas production process were greater than 0.99, and those for the acetic acid degradation process were above 0.90, with the first-order kinetic model demonstrating a better fit for acetic acid degradation.

在电催化作用下,厌氧消化可以提高沼气中的甲烷含量。文章以乙酸为底物,研究了电催化厌氧消化体系的产沼气动力学和底物降解动力学。实验发现,投加不同质量浓度(8.3,10.0,11.7 g/L)的乙酸后,沼气中的甲烷含量随着乙酸质量浓度的增加而上升,当乙酸质量浓度为11.7 g/L时,批次实验的平均甲烷含量达到80.6%。基于电催化厌氧消化过程的碳平衡关系,利用一级动力学模型和Gompertz模型进行了动力学研究。研究表明:3种质量浓度下的乙酸转化效率分别为85.6%,97.2%和97.4%,其中生物质增量占比分别为22.1%,29.9%和28.5%;两种模型对产沼气过程拟合的相关性系数R2均大于0.99,对乙酸降解过程拟合的相关性系数R2均大于0.90,其中一级动力学模型对乙酸降解过程的拟合效果更优。

在电催化作用下,厌氧消化可以提高沼气中的甲烷含量。文章以乙酸为底物,研究了电催化厌氧消化体系的产沼气动力学和底物降解动力学。实验发现,投加不同质量浓度(8.3,10.0,11.7 g/L)的乙酸后,沼气中的甲烷含量随着乙酸质量浓度的增加而上升,当乙酸质量浓度为11.7 g/L时,批次实验的平均甲烷含量达到80.6%。基于电催化厌氧消化过程的碳平衡关系,利用一级动力学模型和Gompertz模型进行了动力学研究。研究表明:3种质量浓度下的乙酸转化效率分别为85.6%,97.2%和97.4%,其中生物质增量占比分别为22.1%,29.9%和28.5%;两种模型对产沼气过程拟合的相关性系数R2均大于0.99,对乙酸降解过程拟合的相关性系数R2均大于0.90,其中一级动力学模型对乙酸降解过程的拟合效果更优。

In electrocatalytic anaerobic digestion, the methane content in biogas can be enhanced. With acetic acid as the substrate, this study investigated the kinetics of biogas production and substrate degradation in an electrocatalytic anaerobic digestion system. Experimental results showed that with the addition of different initial acetic acid concentrations (8.3, 10.0, 11.7 g/L), the methane content in biogas increased with increasing acetic acid concentration. When the acetic acid concentration was 11.7 g/L, the average methane content reached 80.6% in batch experiments. Based on the carbon balance relationship in the electrocatalytic anaerobic digestion process, kinetic studies were conducted using both the first-order kinetic model and the Gompertz model. The study revealed that acetic acid conversion efficiencies at the three concentrations were 85.6%, 97.2%, and 97.4%, with biomass growth accounting for 22.1%, 29.9%, and 28.5% of the carbon distribution, respectively. The correlation coefficients (R2) for both models in fitting the biogas production process were greater than 0.99, and those for the acetic acid degradation process were above 0.90, with the first-order kinetic model demonstrating a better fit for acetic acid degradation.
