摘要
在对产酸相产酸发酵反应体系中可能存在的氧化-还原电偶分析基础上,确立了以H+ H2为主的氧化还原体系,从动力学角度分析了体系的氧化还原电位与pH值和氢分压的关系,并通过实测实验对确立的相应的动力学模型进行了验证分析.结果表明,该动力学模型对于氢分压较高的产酸相反应系统是适宜的,理论值与实测值之间有较好的符合性,可在实际工程中直接应用.
Based on analyzing the oxidation-reduction couples in the acidogenic phase, deduced H+/H2 to be dominant. Described the relationship of oxidation-reduction potential and pH of the mixed liquor and partial pressure of hydrogen in the acidogenic reactor with a kinetic model and demonstrated by an actual measurement experiment. The results showed that the kinetic model was applicable to the acidogenic phase reactor and could be used in engineering practice.
