摘要
本文从厌氧消化体系是对大气封闭的体系观点出发，指出在大气中测定的pH值不是体系的真实pH值，并在建立消化液电荷平衡方程的基础上，阐述了气相CO2分压对pH值的影响。
Based on the anaerobic digestion system is regarded as a closed system. it is pointed out that the pH value measured in atmosphere is not the true pH value of the anaerobic digestion system. After it is established that the electroneutral formula of digestion solution. shows the effect of CO2 partial pressure on pH value.
